Update: Please post new comments in the latest HPMOR discussion thread, now in the discussion section, since this thread and its first few successors have grown unwieldy (direct links: two, three, four, five, six, seven).

As many of you already know, Eliezer Yudkowsky is writing a Harry Potter fanfic, Harry Potter and the Methods of Rationality, starring a rationalist Harry Potter with ambitions to transform the world by bringing the rationalist/scientific method to magic.  But of course a more powerful Potter requires a more challenging wizarding world, and ... well, you can see for yourself how that plays out.

This thread is for discussion of anything related to the story, including insights, confusions, questions, speculation, jokes, discussion of rationality issues raised in the story, attempts at fanfic spinoffs, comments about related fanfictions, and meta-discussion about the fact that Eliezer Yudkowsky is writing Harry Potter fan-fiction (presumably as a means of raising the sanity waterline).

I'm making this a top-level post to create a centralized location for that discussion, since I'm guessing people have things to say (I know I do) and there isn't a great place to put them.  fanfiction.net has a different set of users (plus no threading or karma), the main discussion here has been in an old open thread which has petered out and is already near the unwieldy size that would call for a top-level post, and we've had discussions come up in a few other places.  So let's have that discussion here. 

Comments here will obviously be full of spoilers, and I don't think it makes sense to rot13 the whole thread, so consider this a spoiler warning:  this thread contains unrot13'd spoilers for Harry Potter and the Methods of Rationality up to the current chapter and for the original Harry Potter series.  Please continue to use rot13 for spoilers to other works of fiction, or if you have insider knowledge of future chapters of Harry Potter and the Methods of Rationality.

A suggestion: mention at the top of your comment which chapter you're commenting on, or what chapter you're up to, so that people can understand the context of your comment even after more chapters have been posted.  This can also help people avoid reading spoilers for a new chapter before they realize that there is a new chapter.

Slightly edited the original post to avoid giving away what my readers have finally convinced me is, in fact, an undesirable spoiler. I also hope you didn't mind my removing the mention of FAI, because I feel fairly strongly about not mixing that into the fic. "A fanatic is someone who can't change their mind and won't change the subject"; if we can't shut up about FAI while talking about Harry Potter, we may have a problem.

8TobyBartels8y
Well, you kept it out for a long time.
1Eliezer Yudkowsky8y
A ShoutOut is not the same as contaminating the plot.
2TobyBartels8y
ETA: Spoilers for chapters in the early 100s. Very true, and I don't agree with some comments that I've seen lately (and probably they've been around all along) complaining about all of the shout outs. But we may have more of a shout-out here: there's a strong implication that the Mirror of Noitilov was created by Atlanteans attempting to create an honest-to-goodness FAI to avert an existential threat. Since Atlantis may have created magic entirely, and since there is already a lot of speculation among the fans that the existence of magic implies that MOR is a simulation run by an AI, this would put FAI and the existential threat of UFAI into the background of the world at a deep level. Of course, only you know if this implication and speculation are correct. And either way, I'm not complaining!
5NihilCredo12y
As someone who's often creeped out by LW, I approve.
4Unnamed13y
That's fine. I'm actually not that into AI, so I wasn't thinking about that problem, but you're probably right. I also made a slight edit to your slight edit so that it still sounds like me.

Here's my take on what actually happened in the dojo incident described in chp 19.

Voldemort went there in disguise to learn the valuable martial art. He reacted badly to losing so they put him through the ordeal he described. He went along with it because he wanted to learn the martial art. The ordeal did teach him valuable lessons about losing, and he vowed to learn to control his temper and master tactics of ingratiation and supplication to better manipulate others. But he felt angry and humiliated by it (as he expected Harry to be), and also vowed to return and fulfill his revenge fantasies. So after he mastered the martial art and left the dojo, he came back openly as the Dark Lord and killed them to live out his revenge fantasies and to prevent others from learning the skills (keep science secret). He spared one student who had befriended him (and who probably stood up for him during the ordeal, like Draco to Harry), and he had that student spread the version of the tale that he wanted told (to maximize fear while hiding some of his true powers, and to deflect attention away from the value of that martial art).

For me the most natural explanation of the dojo incident is that Quirrell/Voldemort pulled a Verbal Kint. The setup is just too similar to be accidental. If you haven't seen The Usual Suspects (you should), that means ur vzcebivfrq gur fgbel ba gur fcbg gb znxr rirelbar srne uvz naq gb uhzvyvngr Uneel. I'll be quite disappointed if Eliezer's eventual explanation isn't as good as this one.

That's certainly possible, but we know Q/V does have elite martial arts skills, which he had to have learned somewhere, and studying at the world's best dojo, followed by destroying it to make sure no one else ever got training as good, seems like an entirely plausible thing for a Dark Lord to do.

8Strange713y
My understanding was that the story was true as stated: Voldemort showed up, destroyed the place, then calmed down and realized Quirrell now had the only remaining copy of the information he was looking for, so he set up some contingency to eventually put himself in Quirrell's body with the martial-arts skills intact.
4NihilCredo12y
Is there any hint in MoR that Quirrel was already a total badass before Voldemort's body-snatching job, as this interpretation would require ("I was a prodigy of Battle Magic even then [at the times of the dojo]")?
2Strange712y
I think 'last surviving student of the greatest martial-arts teacher' counts as a hint, yeah. Why would Quirrel's battle-magic skill, or lack thereof, be relevant in Voldemort's choice of host? Magic is at least partly a function of the mind, and judging by the descriptions of zombie-like behavior when off-duty, the body-snatching didn't do Quirrel's mind any favors. Rather, the point would be to combine Voldemort's lifetime of rationality and Battle Magic practice with Quirrel's sixth-dan hand-to-hand combat skill, resulting in a single individual with two lifetimes' worth of powers, without the expense and possible side-effects traditionally associated with magical life extension. Speaking of which, isn't there a prefabricated, ready-to-use Alchemist's Stone somewhere on campus?
4Alicorn12y
Philosopher's Stone, or in the American version, Sorcerer's Stone. Although it does belong to an alchemist.
4dclayh13y
Agreed, except there's no particular reason for a Dark Lord to actually leave a survivor when he can just have his minions disseminate it. (Or do so himself as Quirrell; we have no knowledge of how long this story has been around.) ETA: Actually I should say my first thought was that Voldemort destroyed the dojo not out of anger, but simply to make sure that no rival wizard ever got the awesome martial arts training that he did. This seems strongly implied when he says: "You are wondering where this marvelous dojo is, and whether you can study there. You cannot."
2thomblake13y
As pointed out in the recent Dr. Who series, you occasionally let one go so you can live with yourself.

The fic now has a hate blog dedicated to it.

Congrats Eliezer! Now you've really made it.

The writing style seems to go for similar overkill as in XKCDSucks-blog, that is, every tiny detail is taken out of context and twisted until it is made look bad. Plain honest deconstruction and critique would be fun, as there are many things I think are quite awful with MoR, mostly I dislike the unnatural feeling every single human relationship has and how many speeches about science seem to be a bit unrelated and be there just for lecturing the reader without justification from story, and how Harry seems to be Mary Sue so very much it's actually annoying. MoRSucks however seems to go drowning real bad points into a sea of motivated cognition. It seems bad. Weird and untruthful, strawman-like, as far as I can tell, portrayal of MoR fans doesn't help.

6Democritus12y
That's a really good analysis of the problems with MORSucks. Unfortunately, people who only slightly dislike a work, or acknowledge that has some flaws but enjoy it anyway, seldom form blogs devoted to deconstructing it. In general, you have to choose between overwhelming praise and overwhelming hate.
7Jack13y
So maybe it's just me but my reaction to the fanfic was something like "Eliezer is writing rationalist Harry Potter fanfiction. That's pretty awesome. And educational!" I check it every so often to see if there is a new chapter and I've shared it with a couple people. That's pretty far from: It seemed like most people had similar reactions to mine, but maybe Less Wrongers have been making a bigger deal out of it elsewhere? We didn't even have this thread until a couple of chapters ago. Similarly: My sense was that we had almost nothing to do with the popularity. It didn't get linked to from LW until like chapter 12 or so, if I remember correctly. I know a couple people here made image macros but Eliezer's following isn't nearly large enough to generate this kind of popularity by itself, right? As for the rest of it: it reads like my mother critiquing MTV, the author doesn't understand where the author is coming from or who he is writing for and as a result totally misses his target. For example, the fact that Harry has three last names clearly isn't Eliezer making sloppy feminist statement. If anything, he's laughing at himself and the subculture he's a part of. I laughed out loud when I read it because obviously rationalist-Harry would have a compounded name. It's exactly the right amount of PC-vanity for the family of an Oxford professor with a kid too smart for his own good.
4JoshuaZ13y
I was referred to initially to it by two people who are not LW readers. The individual writing the blog may be suffering from a bit belief overkill (one of my favorite cognitive biases. Someone should do a top-level post about it at some point. Many different cognitive biases can be thought of in a belief overkill framework).
2Jack13y
Is belief overkill different from confirmation bias (which is what comes up when I google)?
5JoshuaZ13y
They're related. Some argue that confirmation bias is an example of belief overkill. Belief overkill is basically the tendency for people to accept all arguments that support their opinion even if it is only in a peripheral fashion. Thus, for example, people who think that using fetal stem cells for medical purposes are moral are much more likely to think that stem cells will be really medically helpful than people who think that such use is bad. Essentially, people compile arguments for why X is Good/Bad rather than dividing questions properly. There are some posts that touch on this issue (such as those discussing why politics is a mind-killer) but I'm not aware of any post discussing this issue in detail (although given how extensive the archives are I estimate a high probability that I've simply missed the relevant ones).
6Unnamed13y
Sounds a lot like the halo effect [http://lesswrong.com/lw/lj/the_halo_effect/].
3RobinZ13y
Policy Debates Should Not Appear One-Sided [http://lesswrong.com/lw/gz/policy_debates_should_not_appear_onesided/] is related to belief overkill, I'd say.
3NancyLebovitz13y
Motivated cognition would also be a special case of belief overkill-- it's being too ready to develop and accept arguments what you want to believe. Belief overkill is the same process applied to arguments from both yourself and other people.
1JoshuaZ13y
Well, so far I'm not impressed by the criticism of chapter 1. I've been meaning at some point to write something about where I think Eliezer's gone wrong, but now I think it might be more interesting to wait and see if this individual produces anything interesting. Given that the individual is a fan of the xkcdsucks blog, I'm a bit skeptical that I'm going to see much of interest. Judging from the chapter 1 review it looks like the writer is having some of the same problems as those people (One major one is assuming that setups or characters are necessarily ideals just because they are sympathetic or protagonists)
1dclayh12y
The Chris Christie joke was excellent, however.
1NancyLebovitz13y
That site does seem like a bad case of motivated cognition, but I'm going to read a little more of it to see whether the author comes up with something interesting. One thing that's mildly interesting is a criticism of MoR as being humanities-deficient. It would be interesting to see someone (possibly not Harry Potter-- he's too young) coming into the wizarding world with a strong humanities background.
4JoshuaZ13y
I read a fanfic a while ago involving a journey to afterlife (set after 5 and written before book 6 had come out) involving a journey to the underworld to try to get Sirius back. Hermione had apparently read enough mythology and other works to become genre savvy about what to expect. The end involved dealing with a creature that had been promised a pound of flesh from Harry and she then used the standard trick from The Merchant of Venice to deal with it. When the others are impressed she explicitly stated where it was from and gave a brief rant about how wizards should read more Muggle writing.
2dclayh12y
I would think using magic you actually could extract a pound of just flesh...
1JoshuaZ12y
Yes, in the story it went slightly differently than it occurs in Merchant of Venice. Hermione waited until after the flesh had been torn from Harry to tell the underworld spirit that it had violated the deal and then negotiated back the restoration of everything as an appropriate penalty for it violating the deal.

That was a hard swat at "The Ones Who Walk Away from Omelas".

As for why Harry has such an exaggerated sense of responsibility, it might be that growing up on science fiction thing. A lot of science fiction is set up so that the hero can have a huge effect in a satisfying way. Perhaps Harry should have balanced it with reading history. On the other hand, he's living in fiction, so maybe he's right for his situation.

Lois McMaster Bujold has described sf as fantasy of political agency [1], and I think she's on to something.

I assume that shutting down Azkaban has a political solution rather than a magical or violent solution. This will be interesting to watch.

Why would Snape ask Harry for his take on Snape's past? One of the underlying premises of the story is that the smarter characters (possibly with the exception of Hermione) always have a deeper plan. Did Snape actually expect to get good advice? To be told that all his choices were correct? To have a reason to be angry at Harry? None of these make huge amounts of sense (to me, at least-- I have trouble keeping track of all the scheming), even though the scene was very emotionally effective.

This is basically my review posted to fanfiction.net-- let me know if there's a problem with reposting such here.

[1] The link goes to quite an interesting speech

Lois McMaster Bujold has described sf as fantasy of political agency [1], and I think she's on to something.

Thanks for that link. To rephrase: unlike romance or detective stories, many SF/fantasy stories are carefully rigged to give the "underdog" protagonists huge power over the world. It's scary how much this pattern fits.

8RobinZ12y
I think he was testing the differences between Harry and his dad, and was surprised enough at the contrast to keep asking questions.
7thomblake12y
Quite the opposite. I was tempted to respond to the review but had been left without an appropriate forum. I had to go back and figure out where you thought the Omelas reference was. Harry's observation just seemed obvious to me. Personally, I don't even see anything to explain. Billions of people are suffering, and at least billions are going to die, and most people are observably doing nothing about it. Harry seems to have good reason to think he's the only one that can do anything, if only because he's the only one (or one of just a few) who noticed and/or cares. Harry is right to take responsibility for the universe's troubles, as we all should. I think Harry was just using Azkaban as an example, and there will turn out to be more of a general solution to the world's problems unless Harry finds himself dealing directly with Azkaban.
-2wedrifid12y
Harry's problem seems to be not that he has decided to do something about it but that he takes pride in feeling guilt over the suffering of everyone (even obscenely evil people). It is on thing to prefer to take over the universe and allow the evil people to live freely in a way that can't hurt others, but it is quite another to be all emo about it. That achieves nothing except allow harry to feel self righteous.
8EStokes12y
IMO he's not all emo about it. He is also aware of his feeling guilty about it and agrees with Neville when he says he's silly. And correct me if I'm wrong, but I don't recall him feeling proud of it.
6Blueberry12y
I also wonder why Snape got offended. Harry's answers were extremely supportive of Snape's situation back then: which makes me think Snape wasn't really offended, just pretending to be. Maybe the whole point was just for Snape to tell Harry the unpleasant truth about his parents in an emotionally powerful way, as a way of getting back at Harry because of his parents.

Snape still loves Lily and was upset about hearing her insulted, was my interpretation.

1Blueberry12y
Awww... but that puts Harry in an impossible position. There's nothing he could have said that would have worked. If he had said Lily made a good choice, that would have directly insulted Snape. And Snape must have known that Harry would be in an impossible position, so he must have wanted to trap Harry into thinking he had done something wrong.

It's not quite impossible. He could have roundly blamed everything on James, casting Lily as a pure, victimized, agency-less casualty of his manipulations. That seems to be what Snape does.

8wedrifid12y
It is possible to respond in a less direct way. Competent social skills would suggest putting very little actual content into his answer. I am less cunning than Harry and not known to be particularly conservative in my expression of potentially provocative positions but even so I do not think I would have all that much trouble responding with tact. Snape would still make a hostile reply but he does that to answers to potions problems anyway. He probably wouldn't be tempted to kill me.
8NancyLebovitz12y
I don't know about you, but having someone tell me I should give up something I've been overfocused on for a long time can be quite painful.

Assuming Snape was genuinely hurt by Harry's interpretation of Lily, I would expect to see a fraying between Snape and the Dumbledore faction as Snape questions why he is so faithful to Lily.

8ShardPhoenix12y
Yes, I suspect that was the point of that scene - to make things harder for Harry by taking away a (secret) ally. That would align with Eliezer's stated philosophy of fanfiction.

Furthermore, the major event in Aftermath 2 is that Snape reads students' minds again-something he agreed not to do under his agreement with Dumbledore. Which is further evidence that he has "gone rogue."

2red7512y
Ch. 18 In Aftermath 2 it seems reasonable that safety of Alissa requires reading her mind. Edit: Thus, the change is that he directly addressed cause of her distraction.
0[anonymous]12y
Seconded. That's what I wrote [http://lesswrong.com/lw/2ab/harry_potter_and_the_methods_of_rationality/27i1] right after Ch. 27 came out: "Nice job turning Snape dark, Harry."
5wedrifid12y
What is most interesting to me is how Snape handles being offended. Snape has been portrayed in this FanFic as being extremely shrewd and self controlled. Harry even made observations along those lines himself, upgrading his respect for Snape considerably. Snape (quite rightly) downgraded his trust in Harry's cunning. I wonder if Harry downgrades his respect similarly. If Severus had the cunning of even the 11 year old Malfoy he would not 'never talk to Harry again". Any benefit that he could hope to extract from Harry is still there and Severus is enough of a political agent to work past some offence when given a few months to cool down.

It seems like the spells in the HP universe are complicated and abstract enough that they must have been designed (programmed?) by wizards long ago, who added them to the laws of the universe and left them there.

Now, if I were designing a spell like the Killing Curse, I would include a little easter egg/safety mechanism: after a thousand castings, it backfires. Choose a number large enough that only a major dark wizard like Voldemort will encounter it, so it doesn't hit some minor villain and spoil the surprise. (Alternatively, rather than counting kills, count evilness, with killing a baby counting for more evilness points than an adult. That would explain why it backfired on Harry Potter, rather than some other victim.)

This is the most sensible explanation I can come up with. Or it could be that it backfired because the third through fifteenth places of the decimal expansion of the local humidity were a prime number, or something similarly arbitrary. But I would be disappointed if it was something like that. (I would also be disappointed if his parents came up with a spell that reflected it, because everyone seems convinced that no such spell is possible.)

9CronoDAS13y
You'd think that, but in the series there are references to people inventing spells of their own. The series implies that the "science" behind spells does exist, but Rowling never explains any of it.
7Larks13y
'Inventing' might mean 'discovering'.
5Eliezer Yudkowsky13y
Not to mention, the ancient wizards made the levitation spell be called "Wingardium Leviosa"?
1NihilCredo12y
Well, the word 'wing' does date back to the 12th century [http://www.etymonline.com/index.php?search=wing], a little earlier than halfway between us and Merlin, and a time in which learned people did know Latin but were also starting to mangle it up pretty badly (not quite that badly IRL, but if we assume wizards were always a bit more eccentric than Muggles...). Unfortunately, that particular fan-wank completely breaks down when you consider that the pronunciation (let alone spelling) of 'wing' was nowhere near the same back then. Although you could save it by suggesting that, just as spoken language evolves really, really slowly, so did the spell-marks imprinted on reality as the spell got cast a million times over a thousand years, a wee little bit differently every time.
6blogospheroid13y
I haven't thought about this idea completely, but a karma system can actually be maintained in a magical society. I mean actual karma, the way Hindus and Buddhists think about. What goes around, comes around. Violate it badly enough and the universe will make an exception just to get you out of the way. As another commentor put it, somebody would have tried to protect another while they were being avara-kedavra'ed, earlier than lily protecting Harry. But voldemort's karma credit really ran out. So, whoopsie, there goes the body. But of course, he had his horcruxes. But if making people realize that we have to wake up in this hostile universe is one of the goals of this fic, the above wouldn't be true in HP&MOR. Another speculation, maybe true prophecies only come when there are serious thresholds crossed.
3rastilin12y
Or maybe it just doesn't work on children? No one knows because no one's ever tried it. If you could program a slaying weapon, what is the one group of people that no-one in their right mind could possibly ever want to kill? I'd say that group would be children too young to speak. Anyone going after them is certainly an absolute psycho.

I just read Chapter 27. My thoughts:

"Mr. Bester" - great reference.

Harry is firmly on the 'get absolute power' path. Probably he still thinks he's being cute or knowing when he talks about becoming God. His resolution not to become the next Dark Lord doesn't look too healthy now, though.

Harry seems incapable of seeing the flaws in a moral system he apparently acquired by reading science fiction and fantasy, barring almost being Sectumsemprad by a very angry wizard. Why does he think that having read books with monomyth plots is sufficient reason to try to act like the heroes of such books - what is he, eleven years old? At the same time, he understands and can nervelessly put to use Quirrell's very subtle lesson in levels of deception. Very odd, that.

Is one of the reasons Quirrell set up those Occlumency lessons that Harry would discover for himself "how reproducible human thoughts were when you reset people back to the same initial conditions and exposed them to the same stimuli" - and thereby come to treat humans as simple machines that one can use like puppets? As a strategy to bring someone over to the Dark Side, that's brilliant.

Then we get to Harry being placed in the same conditions as Lily Potter, and reacting differently - more humanely. Because he reads science fiction! That's outrageous. Surely this kind of narrative based morality, where you imagine what the good protagonist would do and then do that, is going to be a piece of cake for Quirrell to subvert.

7gwern12y
Indeterminate at this point. (By which I mean, even if Eliezer didn't intend Quirrel to have those reasons, he could easily make Quirrel have had those reasons.) The reasons given earlier are quite enough to justify the lessons: Quirrel doesn't want Harry to be easily scanned by either Snape or Dumbledore for obvious reasons, and once he threw his hat in the ring, a neutral third party was the only viable option - and such a neutral third party can only remain neutral by being Obliviated since anyone in the know about Voldemort is, eo ipso , a member of one faction or another.
0cousin_it12y
Just read Chapter 27. Haven't read the original books, but Wikipedia says Snape was a secret agent of good because of his past love for Lily. Nice job turning Snape dark, Harry. Considering your friendships with Draco and Quirrell, I don't see what you're doing out of Slytherin. Also, the chapter reads a lot like Sword of Good. It's not a bad thing per se because a good story needs to be retold several times before it comes out right, but in this iteration the hero's epiphany that "woah, the world contains a lot of pain, gotta do something about it" came out quite a bit weaker. The protagonist in Sword of Good had a device that relayed the world's pain to him, but Harry has to settle with imagining other people in unfamiliar situations. Eliezer could make this plot point hit harder next time by making his protagonists actually see pain and suffering up close.
3wedrifid12y
No, no, this mistake suggests the opposite. No Slytherin with Harry's preferences, intellect and level of development would ever make such an idiotic mistake. A Ravenclaw might. Harry gave the wise, or at least what he considered to be the correct answer, given very little regard to what he was trying to achieve. Self absorbed know it all. Don't even let me start on the pretensions crap about knowing what is good, and more importantly what is wise, by reading it in a fantasy book. Even Hermione isn't that much of a git.
0wedrifid12y
My take: That part reads like a fairy tale that we tell children. It doesn't really convey the difference between Harry being naive, having terrible boundaries and generally being emotionally weak and Harry recognizing 'simple on the other side of compexity' that could apply to constructing value systems. Some of cousin_it's suggestions would help in this regard.
2NancyLebovitz12y
Also, I've been trying to come up with science fiction that has forgiveness as a primary value, and I can't think of anything.
5RichardKennaway12y
Ursula Le Guin, "Four Ways To Forgiveness" [http://www.amazon.com/Four-Ways-Forgiveness-Ursula-Guin/dp/006076029X]
0wedrifid12y
That too. For stories instilling forgiveness I must look to those generated for the purpose of religious indoctrination.

I'm reading MOR with considerable interest and enjoyment-- and recommending it-- but.....

There's a big emotional difference between HP and MOR. In the original, Harry has no friends or allies at the Dursley's. In MOR, his family life isn't great and he doesn't seem to have any friends or anyone he's expecting to miss, but he isn't under constant attack.

Part of the emotional hook in HP is that Harry is almost immediately in a circle of friends and acquires a family in the Weasleys.

In MOR, his best emotional connection is to McGonagle, but it's complicated by his intellectual dominance. None of his close friends from HP are worth being close to (or did I miss someone?). His nearest approach to a friend his own age is Draco, and that's very much complicated by Draco having been raised to be a sociopath, and by Harry's need to manage Draco.


Part of the charm of HP was that Hermione's memory, intelligence, and conscientiousness are presented as more valuable than annoying, though the annoyance for the other characters is still there. This is a rationalist feature of HP which seems to be lost in MOR-- Hermione is interested in getting things right for the sake of status.

Her delight at ... (read more)

that's very much complicated by Draco having been raised to be a sociopath

I need to object pretty strongly to this particular phrase. Draco is not being raised to be a sociopath; he's being raised to be a high-status member of a hierarchical society. Draco and his father very much love each other, and are perfectly capable of making real emotional bonds with people that they have identified unequivocally as 'pack'. EY has actually done very well at showing Draco as what a perfectly normal child becomes in that environment.

This is an important distinction, because we need to remember that 'sociopathy' is a comparatively rare (and usually inborn) condition, while high-status machiavellian narcissism is a natural consequence of human evolutionary psychology.

5NihilCredo12y
I think it's more a matter of approaching romance with the maturity and self-reflection abilities of an eleven-year-old.
2wedrifid12y
In fact Harry himself doesn't seem particularly worth being particularly close to. He'd be a pain in the ass to be around and he's probably going to become a demi-god and care about what you want no matter what you do.
1rastilin12y
I agree to an extent. He does remind me of people I've known in the rationalist movement. It's worth pointing out that him blurting out the wrong thing at the wrong time isn't just an annoying character trait, it's probably symptomatic; I'd speculate he doesn't really consider other people as fellow actors in his decision making. If there was someone who did not make efforts to bond with people around him, would you be willing to trust him with power over their happiness? That's a non hypothetical question, I'd love to hear a rebuttal.
2LucasSloan13y
Hermione?
1NancyLebovitz13y
I should reread, but the most recent chapter with Hermione presents her as a person who's at least much less worth spending time with than the HP Hermione.
3JoshuaZ13y
Really? It seemed that she's just a bit genre savvy. She's an 11 year old who's main understanding of how the world works is from distilling tropes.
0GeorgieChaos9y
The reverse halo effect you describe is called the horns effect.

The hate that the Dark Lord Potter forum has on MoR is getting more than a bit amusing.

Also, perhaps it's me, but I see the story as a thinly veiled commercial for the author's blog/institute, which breaks the "doing this for pleasure and not profit" fanfiction model (as well as being a subtext that breaks the fourth wall for several readers). The author is almost certainly deriving commercial benefit from J. K. Rowling's intellectual property and his exploitation of the popularity of her fandom by routing eyeballs to his site and building his own personal fame as a voice in the field of AI. I wouldn't be surprised if his story has bumped traffic to his blog/website by an order of magnitude or two. In many regards, this practice is worse than a Cassandra Clare or Jim Bernheimer pitching their original fiction novels on their fanfiction sites, since neither author makes a living off their writing.

This story isn't parody in the traditional sense, so it's possible that a court would consider it as not falling within this protected class of derivative works. Indeed, if the legal hammer were to fall on this story, it could have fallout: consider that a single CAD letter, if

That thread is an interesting read. Fun to see people taking this so seriously. Personally I just like that it is educational material presented in a fun to read fashion that pokes fun at a rather silly story / fictional universe that has been forced upon us all by the engines of cultural osmosis. I have no problem with HP used as a cheap mnemonic device to memorize and illustrate a set of concepts that everyone should know but most people don't. I also don't have a problem with using it as a cheap advertising gimmick to get people to pay attention to matters that they should be paying attention to but don't. The annoyance of DLP folks at this is understandable, but somewhat hilarious from a perspective that thinks of there as being more important nerdy things to obsess over in life.
4thomblake12y
Yes, it seems to work great for that. I find myself saying things like, "As Lucius Malfoy would say, that sounds like the sort of plot that would work in a story but not in reality." or "That's like the time Harry Potter..."

What happened to the Harry from Chapter 6?

"Um," Harry said, "can we go get the healer's kit now?"

McGonagall paused, and looked back at him steadily. "And if I say no, it's too expensive and you won't need it, what happens?"

Harry's face twisted in bitterness. "Exactly what you're thinking, Professor McGonagall. Exactly what you're thinking. I conclude you're another crazy adult I can't talk to, and I start planning how to get my hands on a healer's kit anyway."

A time turner is a superior to a healer's kit in very nearly every way and by a huge margin. Yet all Harry does when he loses free access to his time turner he sulks a little and that's all. He doesn't plan at all! I don't even recall one line of introspection on the subject! It takes very little ingenuity to to react:

"Harry, give me your time t..."

shit. shit. shit. Activate time turner. Escape. Then, he can spend five minutes and think up a dozen ways to retain time travel capability. Let me see...

  • Create a fake...
    • Lie to Hermione to get assistance?
    • Transfiguration not likely to work, given the teacher responsible.
  • assume that wizarding security is crap and guess (corre
... (read more)

First, Harry discovered a gag beverage that he thought could be a key to power, although he quickly realized the Comed-Tea wasn't as powerful as it seemed. A few days later he fell in love with a device that is sometimes given to students who want to take extra classes, although he has since discovered some limits to its powers. If he goes rogue over his Time-Turner's crippleware, then who knows how much other cool and useful magical stuff he will miss out on, and how much trouble he'll be in.

Plus, McGonagall had him cornered when she confronted him about returning the Time-Turner - whatever he tried to do, she'd see it. Also, McGonagall had earned some degree of trust & respect from Harry, she's correct about Harry repeatedly misusing the Time-Turner, and she'd already warned him that they'd take it away. So it's not unreasonable to go along with the punishment, and try to earn her trust back so that his Time-Turner can be restored later on.

6Eliezer Yudkowsky12y
...don't take this the wrong way, but even Harry knows better than that. If you genuinely think this is a smart thing to do in real life, it makes me seriously worry about your safety and the safety of people around you.
4wedrifid12y
There is NO DOWN SIDE! It may be best to hand over the time turner but you do so after having a chance to think it through. Time turner. Plan. Decide that it is better to hand over the device for now. Write your analysis down. Give it to yourself at the appropriate time. (And give it to yourself again to make the loop stable.) I have offended you by questioning the rationality of your fictional persona. My own safety is not in any danger. Every other exceptional use that Harry put the device to is risky and I would not do any of them. But giving himself a chance to think through his options in a way that would not be detected by anyone else is the trivially correct strategic option. My own safety is secure in the short term, and medium term (human life span) but for the long term the threats to my life are human mortality and existential risk. And that's kind of what I've been counting on you to take care of (with any contribution that I could hope to make purely financial). That being the case, this conversation is quite literally scaring me. I'm not quite there yet, but the key quote from Snape is at least springing to my mind: "And I no longer trust your cunning." Examples of stupid things to do with a Time Turner: * Throw pies at people through misguided altruism. It would be better to let them break your finger. You're at Hogwarts... a 5th year Luna could fix it. * Have a dramatic stand off over a rememberall. If it is so important... use the time turner to find and or steal the thing beforehand and leave it somewhere Neville will find. I mean seriously... using a time turner in a way that is detectable is for emergencies! * Disappearing acts from a class room. Of all the things to do with a Time Turner in that situation making a bigger scene is not one of them. At the very least, if you must refuse to be bullied, write yourself a note telling yourself to not attend potions and make another arrangement. It would be much easier
6Sniffnoy12y
You seem to misunderstand how the time-turner works (or at least, how it's been suggested it works). You don't get to overwrite anything; the universe doesn't "end up in" a stable state that results from using it; there isn't any meta-time (or at least, we've seen nothing to suggest such). If he were going to use the time turner to give himself advice, he would have already gotten the advice. And having used the time-turner right there and visibly, he couldn't use it "later not use it there" and have his going back in time undetectable. A possible way he could use the time turner to help himself in this case would be to ask to go to the bathroom or somesuch, use the time turner, use the extra time to think, and then return to the room shortly after he left having thought about things. (Edit: But this would be pretty obvious, and McGonagall probably wouldn't let him leave the room with the time turner in any case.)

You seem to misunderstand how the time-turner works (or at least, how it's been suggested it works). You don't get to overwrite anything; the universe doesn't "end up in" a stable state that results from using it

My interpretation of the "DO NOT MESS WITH TIME" incident was that you can try setting things up so that temporal consistency implies the result you want, but actually ruling out every other possibility whatever, including vast classes of outcomes you never even imagined, is next to impossible, at least for an 11-year-old boy, however smart. It hadn't even occurred to him that there was a problem in his reasoning when he tried the experiment that gave him "the scariest result ever in the history of science". Temporal consistency in the presence of time loops is another blind idiot god, far more swift and powerful than evolution.

Anyway, he still has the Time-Turner. All that stands between him and it is a magical lock. How difficult can that be for him to get around? No, actually what stands between him and it is the author's necessity not to unbalance the plot by giving him a get-out-of-jail-free card.

6Vladimir_Nesov12y
Harry's error in the experiment was responding to "DO NOT MESS WITH TIME" with the same. If he didn't have the property of responding to that message with the same, that message wouldn't appear. Actually, this whole consistency-based time travel seems to be an extremely expressive thought experiment infrastructure for thinking about Newcomb-like problems and decision theories able to deal with them. Maybe I should do a top-level post on that (I don't have a sufficiently clear picture of the setting, so I might be wrong about its potential)... Though I consider that happening unlikely, so other people who understand UDT [http://lesswrong.com/lw/2di/poll_what_value_extra_copies/26vb] are welcome to try.
1wedrifid12y
I was thinking exactly the same thing. After getting my head around the implications it seems to be an extremely intuitive way of handling such problems. I didn't write a post myself since I have yet to look close enough at UDT to be able to explain the difference between UDT and TDT.
3wedrifid12y
I think you summed that up perfectly. I would have liked to see a little more of that explanation in the Fan Fic. It would make the story feel more natural and also be a perfect excuse to include the 'blind idiot god' kind of message. Without Hermione backing him up? I think he'd struggle. Harry just isn't that smart! He really should be spending more time sweet talking her. Well intentioned genius with ambition that doesn't involve gaining power... just the kind of ally Harry needs. Uh huh. It's even worse than if Harry had actually gone and made himself rich on day 1!
2LucasSloan12y
He has been rich since day 1, it just that all his money is tied up in a variety of non-liquid "investments."
0wedrifid12y
I should say "insanely rich", not merely 'well off heir'.
3Eliezer Yudkowsky12y
Time travel in this universe has a consistent single line; once McGonagall sees Harry disappear, he can't undo it.

once McGonagall sees Harry disappear, he can't undo it.

Sounds like UDT might be applicable here. Here's a time-traveling version of Counterfactual Mugging:

Harry appears to McGonagall and tells her, "If you give me 1 Galleon now, I'll go back in time and hand you 100 Galleons an hour ago." Suppose McGonagall does not recall being handed 100 Galleons an hour ago. What should she do?

Here's my analysis. Suppose McGonagall decides not to give Harry 1 Galleon, then there are two possible consistent timelines for this universe. One where McGonagall gets 100 Galleons, and one where she doesn't. How does the universe "choose" which one becomes reality? I don't know but let's say that the two possibilities have equal chance of being true, or get equal amount of "reality juice".

Given the above it seems clear that McGonagall would prefer to have pre-committed to "give 1 Galleon even if not handed 100 Galleons an hour ago" since that would make the "not get 100 Galleons" timeline inconsistent. I think that's also UDT's output (although I haven't written down the math to make sure).

ETA: I didn't follow the previous discussion closely, so this might not apply at all to it. Hopefully, in that case the above is of interest in its own right. :)

6topynate12y
Seems straightforward to me. McGonagall knows that she does not recall being handed 100 Galleons an hour ago, so the three states of the world with high probability are: 1) She is not in a universe where she will hand Harry 1 Galleon, 2) She is in a universe where she hands Harry 1 Galleon and Harry breaks the agreement, or 3) She is in a universe where she hands Harry 1 Galleon and Harry keeps the agreement in a way that leaves her unable to recall this happening. By not handing Harry a Galleon, she will ensure that she is in universe 1. By handing Harry a Galleon, she will find herself in universe 2 or 3. She should therefore give Harry a Galleon if she judges it less than 99 times more likely that Harry will break the agreement than fulfil it in a way consistent with her experience. As Harry has access to a time machine, he doesn't need to decide to give her 100 Galleons before he gets the 1 Galleon, so the situation is quite different to one based on predicting her actions, as Omega does in the Counterfactual Mugging. Rather it has most of the properties of the forward-time version of the gambit: "If you give me 1 Galleon now, I'll hand you 100 Galleons in one hour", except that McGonagall has a big piece of evidence that the promise will be broken, namely that she doesn't remember it being kept.
0wedrifid12y
Vladmir and I agree with the applicability of UDT and have suggested time-travel-with-consistency is a good way to consider Newcomblike problems and the the decision theories that can handle them.
-1Blueberry12y
Precommit, give him the Galleon, then reach in her bag to get the 100 Galleons. (She must have been Obliviated; otherwise, she would remember.) You can actually get around a lot of the problems with time travel by taking advantage of the difference between observation and reality. For instance, if you see one of your friends die, you can go back in time, save him, then plant a fake double so you still have the same observations.
-4Vladimir_Nesov12y
You can never know consistency, can never rely on it, otherwise you are inconsistent (2nd incompleteness theorem).
4Blueberry12y
Though Godel was interested in time travel loops [http://en.wikipedia.org/wiki/G%C3%B6del_metric], that's not the type of consistency that his Second Incompleteness Theorem discussed (it's limited to formal axiomatized systems that can describe arithmetic).
0wedrifid12y
I suspect Vladmir is considering the system in question here in a way that meets that description.

3Alicorn12y
McGonagall went a fair way towards earning Harry's respect, with her behavior about the med kit among other things; he is inclined to tolerate (with however much whining) her authority, particularly on school grounds.
6wedrifid12y
Respect is all well and good... sure, maybe he will do some detention some time. But this is a matter of survival and something that can help him in a broad manner to achieve just about all his goals. This is compared to Snape who.... said some things that might hurt Harry's feelings. Harry isn't acting like a rationalist. He's acting like a nerdy ape.
5CronoDAS12y
He's eleven years old.

He is a week older than he was a week ago. So again I wonder what happened to the Harry from chapter 6?
2CronoDAS12y
I think he doesn't want to become a criminal by stealing the Time Turner.
2wedrifid12y
This doesn't warrant one sentence worth of inner dialog? Seriously not buying it. It's a different Harry hacked together for a different parable and as a plot hack to get rid of the Get Out Of Jail Free Card of Awesomeness +4.

He can't have inner dialogue during that section, it's in Minerva's point of view!

5wedrifid12y
That's a good reason. So are you saying that Harry actually did do a thorough analysis of his optimal strategy for securing the benefits of time travel for "actually 5 minutes" at some stage but we just don't hear about it? This would make the situation credible.
4Eliezer Yudkowsky12y
No, Harry's experimental result scared the hell out of him and he decided not to do any more clever experiments until he was fifteen. This is actually more rational than what you are advocating.
5wedrifid12y
Are you sure you understand what I'm advocating? Your claim here suggests to me that you do not. The most probable outcome of the thought process I outlined, and I say most probable because this is what my reasoning concluded but Harry is smarter than me, is that he will go and earn enough enough money to buy a time turner just in case. I aren't advocating the use of the time turner to make reckless experiments or any of the non-authorized uses that Harry had previously used the device for. I actually made it quite clear [http://lesswrong.com/lw/2ab/harry_potter_and_the_methods_of_rationality/27u3] what I thought of clever experimentation when explaining the note I would send myself. "Arrogant git" was the key phrase if I recall. What kind of usage is sane? Emergency usage. For example, I would advocate the use of a time turner when locked in a room being tortured and at a high risk of suicide if I do not prevent it. (I liked the touch with the destroying all sharp objects too.) I would also advocate the use for saving lives (including his own depending on circumstances) with minimalist interventions, many of which would be not at all experimental given what he has already safely gotten away with. It would also be extremely valuable in the reduction of risk to have an extra 36 hours available for emergency use. Many threats to Harry's world optimisation plans will come with some warning. Impending attack of some sort, etc. Having a turner on hand means that he would be able to take more time to make preparations or give th device to McGonnagal in the emergency situation and allow her to prepare. As far as either myself or Harry know she isn't wise enough to have one on hand herself. A time turner is a device that is massively useful and it is massively useful even if you use it conservatively and take no risks with it. Having one on hand does not make bad things happen unless you know you will be unable to control your foolish impulses. This is not Harry's reas
1CronoDAS12y
That's a good answer.
0red7512y
Timeturner awesomeness for jail escape is pretty much discounted, when jailers know that one has it. And Harry risks being put under constant supervision because of his apparent disability of infancy.
1wedrifid12y
It never occurred to me to consider it a literal way to escape from jails. That's nearly useless. Instead, I consider it, among other things, as a nearly universally more effective med. kit. If someone just fell off the roof would you rather be able to bandage them up a bit or go back and tell them to watch their step? ... a good reason to not do things that are infantile... and when you do slip up you go back and give yourself a scolding so that you never do the infantile thing in the first place (but still give your past self the scolding note).
9Eliezer Yudkowsky12y
Good heavens, Mr. Wedrifid, you can't change time! Do you think students would be allowed Time-Turners if that was possible? What if someone tried to change their test scores?
7wedrifid12y
Good heavens Mr. Yudkowsky, I thought the inventor of Timeless Decision Theory would have a better grasp on how being the kind of person who would make a certain decision can determine what happens, even when that decision never needs to get made, whether that be with Omega and his boxes or in the stable resolution of time loops. In all the previous time related events, things worked out how they did because the situation in which Harry did not use the time turner was not stable. If Harry was different (for example, by being Hermione or by not having a Time Turner) then the stable, 'final version' given by the universe-time-loop-processor would be the simple one where he doesn't go mess with stuff. But it wasn't. But lets say that for some bizarre reason Harry never found a note warning him about a stumbling risk and he didn't think to send one back later. At the very least we should find out a few seconds later that the friend fell off the building and landed on a great big padded mat.

Good heavens Mr. Yudkowsky, I thought the inventor of Timeless Decision Theory would have a better grasp on how being the kind of person who would make a certain decision can determine what happens

I do indeed.

I've written unpublished fiction about it.

From before TDT was invented, actually.

Harry has not worked all that stuff out yet.

He did work out one important principle so far.

It is called DO NOT MESS WITH TIME.

And considering that he got that result, you seem to have missed some of the implications for how time travel works in that universe which would make it potentially dangerous to try and blackmail reality.

Time travel was the first optimization process I considered which was truly alien enough to deanthropomorphize my thinking; evolutionary biology didn't do the job, but the unpublished story I was writing about time travel did.

What you're suggesting is a bit more potentially incredibly dangerous than you seem to think.

2wedrifid12y
I think you are mistaking me for straw-wedrifid here. I saw the problem with trying to blackmail reality before he went ahead and actually tried it. But then I'm not eleven and while I am arrogant I am not nearly as arrogant as Harry seems to be.
5Vladimir_Nesov12y
Exactly. To make certain situations impossible, you have to be the sort of person that makes the correct actions in the impossible situations, the actions making those situations impossible. (This is also at the core of bargaining.) You are not to take the money from two boxes in the Open Box Newcomb's problem, even if you clearly see that money is there in both of them (and if you have that property, then the situation will never arise).
1CronoDAS12y
Harry tried "being the kind of person who would make a certain decision" when using the Time Turner. The result was DO NOT MESS WITH TIME.
3thomblake12y
He was trying to create a stable time loop, which had consequences along the same lines as the Outcome Pump [http://lesswrong.com/lw/ld/the_hidden_complexity_of_wishes/] - there's no way to know which stable time loop you'll get. However, if he was using a "being the kind of person" strategy, we might expect he'd avoid being the sort of person who would pass along "DO NOT MESS WITH TIME".
3Sniffnoy12y
Yes, to repeat what I said earlier, this seems easy to avoid by replacing his "blank paper" condition with a more general "anything other than a pair of numbers in the given range" condition. I have to suppose Eliezer had him get that specific message because it wouldn't be good for the story if Harry noticed this fact. Though even if he does take that approach, as with the outcome pump, there's still other possibilities, because they can screw with Harry's ability to execute his intended algorithm.
3Vladimir_Nesov12y
Yes, like it turning out that he was predetermined to die at the time of the experiment, and never complete it.
1wedrifid12y
He did the same thing every time he used the time turner. I mean every time, even the times when he was being a good boy and using it to manage sleep. the universe doesn't care whether it is a conversation with McGonnagal, juggling bullies and pies, someone falling off the roof or just bed time. What does matter to the universe is whether the agent in the time loop is interacting with the time loop in a way that is complex and improbable. That is, factoring large primes should give unpredictable outcomes, long detailed tricks like throwing pies and playing with bullies should be slightly safer, giving yourself a time out simpler again and pre-sheduled study and sleep breaks right down at the bottom of the scale. I argue that all the instance of time turner differ use differ only in degree. There are many things to do with a time turner that are far, far less disruptive, complex or unstable than what Hermione did when attending multiple classes. Given her interaction with other people who would be encountering her other self there are butterfly effects that would need to be resolved by the system. If Harry set up a smart system to communicate with himself unobtrusively things may be simpler to predict. He could send himself SMS messages (when outside Hogwarts) or use one of those coins to send messages.
4Vladimir_Nesov12y
This "scale" sounds extremely anthropomorphic.
-3[anonymous]12y
An artifact of human language. The easiest way to describe most things (right down to basic forces) tends to be anthropomorphic.
-1red7512y
As Eliezer said already, timeturner can't change the past. One generally can't even calculate probability of desired outcome of timeturning... Ouch. This is discussed already.
2NancyLebovitz12y
If anyone wants some sf on the subject, I recommend Leiber's The Big Time and "Try and Change the Past". They're both based on the same premise. The timeline is changeable but highly resistant. Humans can't change it (that's the short story) but there are two superhuman sides (called Snakes and Spiders, but never seen onstage) which recruit humans who are willing to be cut out of their timelines just before they die.
2Vladimir_Nesov12y
Probability is in the mind. It is the thing that is being calculated.
0red7512y
And the thing is "DO NOT MESS WITH TIME".
0wedrifid12y
That is a significant quote from the FanFic but I am having difficulty seeing it as relevant to Vladmir's statement.
-1red7512y
I found Vladimir's utterance (I'm not sure of word's connotations, I use it in pragmatics sense) incomprehensible on my current level of understanding his intentions and his ways of expressing toughts. So I've took literal meaning of his words into current context. However, beside joke part my message points on difficulties in dealing with stable states of closed time loops (the thing).
2wedrifid12y
This is not an unusual occurrence. V thinks clearly, and thoroughly but presents his conclusions in a way that assumes a similar thinking style and a lot of shared prior knowledge [http://wiki.lesswrong.com/wiki/Inferential_distance]. Petty things like 'intermediate steps' are not necessarily included.
0wedrifid12y
I disagree with this statement. See earlier discussion of 'idiot god' by Richard.
0red7512y
Those closed time loops are weird. I considered timeturing before outcome, but, yes, even in that case one can be told by one's timeturned twin, that all is set up for good outcome. And timeturing after desired outcome... should be done unconditionally, as you can't know it is not you who caused this outcome. Weird.
2wedrifid12y
Definitely weird. A related consideration is that I would always give reasons for any advice I give my former self. That cuts off a large swath of potential stable loops that consist of me giving myself advice for absolutely no reason at all except that it happens to be stable. The better the reasons I have been given myself the less likely it is that the self perpetuating cycle is a completely arbitrary cycle. For example, I wouldn't have sent back "Don't mess with time". I would have sent "the universe doesn't particularly care about your rules and plans you arrogant little git! What's more likely, guessing your way through 128 bit encryption or something seriously nasty that distracts you from your games, such as ? That's right. Think." (Yes, I'd include the 'arrogant git' part. That is information I would clearly need to be reminded of!) Now, not all scary situations give me the chance to write an explanation but a large swath of the probability mass does. While I would still follow the hastily written directive I would also know that to write that particularly message something really bad must be happening. Without having a predetermined policy for giving details I would have no idea whether the message meant something bad almost happened or not. (It also means that I am far less likely to get such a message - I'll probably get one of the many possible detailed messages.)
-1red7512y
The problem is that you aren't source of advice, you are one of constraints to be satisfied. Any message, that you will reproduce with picometer precision and that will create stable state, will do. Precision isn't a problem in deterministic world, and maybe in quantum one too (if our neurons are sufficiently classical), but I'm hesitant to estimate influence of one's preferences on stable state.
0wedrifid12y
I am both. The advice that I will choose to give is determined by the same physics that allows me to breath. Regarding quantum effects - the uncertainty effects can be amplified based on the elimination of unstable loops. Most obviously when my behavior is determined by a quantum coin. The way that plays out looks seriously when pictured in 4 dimensions.

Wait a second, you will not choose an advice. You will reproduce the advice (consistency constraint!). And for the advice to be advice you choose, it must be physically impossible to you to reproduce anything you think is not of your origin. I envy your self-esteem. Edit: Given condition is sufficient, but not necessary.
2Vladimir_Nesov12y

David Brin is apparently now a fan of MoR.

I just finished reading the Russian novel "Lena Squatter and the Paragon of Vengeance" by SF author Leonid Kaganov. It's not exactly a Harry Potter fanfic, but it's very similar to MOR in that it tries to present an explicitly rationalist hero, and IMO Kaganov has handled the task better than Eliezer.

The protagonist is an unattractive and immoral woman whose only strength is extra rationality, which she applies to the sordid and corrupt world of Moscow corporate politics. Using the familiar LW intellectual ammunition - from Pascal's Wager to evolutionary psychology - she gets people fired for talking back to her, gives and takes bribes, blatantly manipulates men (driving one to attempted suicide), and then in the end when she's found the perfect boyfriend her plans neatly backfire, forcing her to kill him and then herself. Lena's exploits are shown with a lot of detail and believability, and overall the book has punched me harder than anything Eliezer wrote. Unfortunately it's unlikely that it will ever be translated into English.

5radical_negative_one13y
Given that one of the catchphrases around here is "rationalists should win", i'm curious why the main character of this story loses in the end. Why would her plans "neatly backfire" in the end, or is it enough for us to admire her rationality that she almost achieved her goals, despite her lack of obvious assets?

4listic12y
Thanks for trying. Please keep us updated. I was thinking to introduce some English-speaking audience (represented by i.e. Less Wrong and Hacker News) to Leonid Kaganov for quite some time. I absolutely don't feel able to translate a whole novel (and I haven't read Lena Squatter yet, as it's quite recent) but I think I can pull off translating a short story or a blog post. The best story of him that I've liked so far is Predator's Epos (2001) which depicts a dramatic incident in space and tries to analyze human ethics through the eyes of an alien studying human epos and comparing it to other species'. The short story, as author noted in his blog, was written on a crunch for a short story competition, which had a theme "a knight quests for saving a princess from a dragon" and, would I say, the author had his fun with the theme. To my mind, the story remains one of his best to date. Definitely best of short stories; I haven't read the more recent of his novels; he might have improved in the recent years, but as of several years ago, I had an opinion that Kaganov is the kind of author for whom the short story format and good crunchtime is an optimum format; the longer stories I read feel watered down. I appreciate that it takes more work and skill to forge a novel while maintaining reader immersion and the pace of the story, and everyone has to start somewhere, but still - I liked his short stories and some of the blog posts best. Which brings me to the topic that Kaganov raised that I wanted to translate and link to on Hacker News. At the time when he finished Lena Squatter he wrote a very detailed blog post where he said he is at the turning point in his career where the sales of his new book (Lena Squatter) will determine whether he will be able to support his family by starting to write novels full-time or will have to earn money the other way (programming) and have little time for writing. So he asked everyone who would consider reading his books to go buy Lena

It looks from my casual observations like the difference between pirated and not pirated (as opposed to plagiarized and not plagiarized, which is a different matter) isn't whether something is in the public domain, but whether it is freely available. As long as it is easy to get a work for free from the author's preferred distribution method, there's little to no incentive to get it with more hassle from a different distribution method. So putting his prior works in the public domain probably isn't getting this author many bonus points, compared to an author who retains copyright or Creative Commons licensing but still makes the work freely readable.

There is no way that he addressed every possible concern to the satisfaction of his audience while charging money for his book. Money is a concern, and while his book might be inexpensive, adopting a general policy of buying inexpensive books when someone asks nicely isn't, and making many individual decisions about when to buy them and when not to isn't either. To an audience accustomed to getting reading material for free, a demand that they shell out money for a new book feels like extortion, and that provokes negative affect ind... (read more)

Incidentally, some online content creators [http://en.wikipedia.org/wiki/List_of_self-sufficient_webcomics] have been able to support themselves through means other than selling their work directly.
4CronoDAS12y
Yeah, things like that happen in the rest of the world, too. Creators of software are hit pretty hard, as do people who make things that are easily converted to digital format. (Printed books are kind of hard to pirate, because you have to put every single page into a scanner, one at a time, instead of just sticking a CD or DVD into a drive, but it still happens.)

Given the generally awful quality of translations into English done by Russians, I hope the eventual translation will be by a native English speaker who knows Russian, not the other way round. That was actually one of the reasons I refused.

Reply to this comment if you found LW through Harry Potter and the Methods of Rationality!

A survey for anyone who cares to respond (edit: specifically for people who did find LW through HPMoR):

  1. Had you already registered an account before seeing this? (Edit: That is, had you already registered an account for a reason other than to reply to this comment?) If not, had you been planning or expecting to?
  2. Have you been reading through the sequences, or just generally looking around and lurking?
  3. What new rationality skills that you learned from HPMoR or LW have you found most useful? Most interesting? Most change-the-way-you-look-at-everything-ly?
  4. Have you referred anyone else to HPMoR? Have you referred anyone else to LW?
9Elizabeth12y
1. Yes, I had registered an account, and had managed ten whole karma points as of this post, of which I am rather proud. 2. I have been reading through the sequences. 3. I've found a lot of the biases fascinating, particularly when it comes to testing a hypothesis, and I just finished a sequence on words and definitions, which I quite enjoyed. 4. I've attempted to refer a couple people, but found that my brother had already found Less Wrong independently (and hadn't told me about it!).
4alethiophile12y
I knew of LW's existence before HPMoR, through the same source that referred me to HPMoR (ESR). 1. I registered mostly to comment on this post. 2. I've been reading the Sequences. 3. More stuff about Bayes' Theorem (my extent of knowledge before I read the Intuitive Explanation was the idea that there will be many false positives on searching for rare events). 4. No.
4fraa12y
1. Yes, I made an account shortly after I read HPatMoR. 2. I've been taking peeks here and there. I mean I was aware of Less Wrong existing before. I've read stuff by Eliezer before, specifically the first contact story, and I found it fun if extremely formulaic and didactic. It was a pleasant surprise for me, that I could find something so stilted so fun. 3. I haven't noticed anything I haven't heard of before. 4. I've referred people to HPatMoR but not LW.
4JoshuaZ13y
I don't exactly fit your set since I had seen LW before, but there's some good reason that I should be included in your sample. Explanation follows: I had read most of the sequences before (and frankly didn't learn that much from them. A handful of cogsci and psych classes along with a fair bit of phil sci gives one a lot of the same material) and had previously read some of Eliezer's fiction. I hadn't really taken that detailed a look at LW as a whole, until HPMR. That was partially due to a conversation with a friend that went something like Friend: So who is the author of this stuff? JZ: He's Eliezer Yudkowsky who is an all around very bright guy. He has some a bit off ideas about the Singularity. Friend: What evidence do you have of that he's bright and not just a good fiction writer? The one thing you've mentioned is something you disagree with. JZ: Um, let me get back to you. Then when reading I felt a need to register an account to make a comment, and then it has been downhill from there (I just linked an LW post to a friend who said that she refused to read it because "I'm not sure I'm willing to let myself -oh god oh god- be sucked into Less Wrong. I have heard it wastes time like tvtropes on crack." I'm not sure if that's a good or a bad thing). I've linked HPMR to a fair number of people, and it seems to be having some impact on some of them. Indeed, it seems that it is quite effective at getting through defense mechanisms that some people have against being more rational, because the arguments aren't being coached in an obvious way of trying to just present what is wrong with their thinking processes. I'm running into concerns about whether linking HPMR to people without telling them about that is ethical or not.

That which can be destroyed by the truth should be.

(On the other hand, Michael Vassar often claims that this quote is as disingenuous as a strong man saying "That which can be destroyed by lions should be.")

7Blueberry13y
I'm not sure I understand. Lions can destroy any human, no matter how strong, right? Is the implication that truth is a weapon? Or that the only people who support truth are the ones who think they're right? But people frequently think they're right when they're not.
2RomanDavis13y
If you are rational, you both are already more likely believe things that are true (or less wrong than your competitors) and more able to defend your false beliefs using knowledge of argument and cognitive biases. Substitute well armed for strong if you like.
2Blueberry12y
"Well-armed" makes a little more sense, but I still don't think it's a good analogy. Lions destroy people who aren't well-armed, so it's disingenous for a well-armed person to say that a fair procedure for who lives is to let the lions attack and see who survives. Truth destroys false ideas, not people, and people frequently don't know in advance which ideas will be destroyed by the truth. People, even rational ones, are often wrong in their predictions, unlike the well-armed man. A precommitment to letting experiments and truth decide what ideas will survive doesn't stack the deck in your favor, unlike in the lions example. The whole point is that you are willing to take the chance of having your ideas die, as long as the true ideas survive.
5RomanDavis12y
I think you could say that the truth does destroy people. You can't be the same person once you've really accepted an entirely new, important idea, and rejected an old belief. When someone says "that which should be destroyed by the truth should be" and he's talking to a Christian or a white supremacist or thousand other people defined by the silly idea they take very seriously, you are often asking them to do something a lot more scary than go up against a lion. If you've already seen the truth and accepted it, the deck is as stacked as it could be. And if you haven't but are otherwise making your bet rationally, while the other is not, then you've still got a lot better chance.
1JoshuaZ13y
And if that destruction itself requires withholding information? In most contexts I'm pretty sure most people here would think that something of the form "I know I'm right, but they'll more likely to not believe the truth if I don't tell them X" is not good rational behavior.
3MadBoat12y
1: No. Most of my time I was lurking. Lot of stuff on LW. 2: Following links, like I was on TVtropes 3: Nothing yet. Eliezer has a distinct way of expressing himself, which is why I enjoy HPMoR, but most of the ideas he is expressing I have heard before. 4: Yes to HPMoR, no to LW.
3BohemianCoast13y
You're not very rational for a bunch of extreme rationalists, are you? It's only possible to answer this survey if you register for the site, so excluding nearly all possible commenters (there is science on this) and presumably an even greater proportion of those who are uninterested in the ideas in LW. So that's a Big Old Fail. So, here goes: 1. No, I have registered purely for the purpose of replying to this comment. 2. I started to read through the Sequences, but they rapidly set off my nutcase detectors. So you might want to do something about that. But I was interested in who had written the fan fiction; and quickly found this thread. 3. I have learnt that there is a community of extreme rationalists who believe that humanity will soon use science to cheat death. Actually, I already knew that. But I have found one of their websites. I was already familiar with most of the philosophical tropes explored in HPMoR; I don't think it would be anything like such a good story otherwise, and I think most of the readership will be people who are already relatively rational. So in terms of 'raising the sanity waterline', an endeavour which seems to be entirely worthwhile, I am not sure it will do that. 4. I have and will referred people to HPMoR. I have not referred anyone to LW.
9Jack13y
You really think we've never talked about selection bias here? It is constantly a concern every time we do a survey. This is why ata's questions were directed at those who had registered and not at the entire group that read the fanfiction. If you know of some way we could poll everyone who read the fanfiction without response bias by all means tell us. Something about us rubbed you the wrong way. Which is fine, things about us rub me the wrong way. But I'd much rather you articulate what that was than go searching for random things to criticize us about just because you want us to be irrational. What specifically?
3CronoDAS13y
Please Elaborate.

Are you asking because you don't know, or because you want to know which ones BohemianCoast noticed?

Most of the world is wrong. Formal education is overrated. The world as we know it is may cease within a century. Lots Of Math. Simultaneously mentioning the word quantum and talking about psychology. For that matter, mentioning the word quantum.

Those are just the ones off the top of my head, and I'm not BohemianCoast. But a lot of stuff written here (and in the "Sequences") is true despite setting off nutcase detectors, not without setting them off.

9Risto_Saarelma13y
There Isn't That Much Math, Really. And none of the cargo-cultish use of mathy writing as impressive-looking gibberish that tends to mark nutcase stuff. Agree with the rest though. Oh, and also: The scientific method is poor and needs to be improved. A central notion on physics held by most practicing physicists is fundamentally misguided.
5Perplexed12y
I've seen plenty of nutcase-stuff in which the math wasn't gibberish - it was correct as math but was simply window-dressing for the nutcase argument. Sometimes, it seems that EY is just using it as garnish for his arguments as well. So, I think that there is a kernel of truth in what GuySrinivasan said about the mathiness of the site. It fits the pattern. Which is not to say that EY is a nutcase. Those nutcase detectors may be returning false positives. But that doesn't mean that the nutcase detectors are defective.
0[anonymous]13y
CronoDAS definitely knows that Eliezer is not a nutcase. He's very rational and well-informed.
2TheOtherDave12y
1. Yes. I went from LW to the OB archives, I created an account to comment on an old post there. 2. I've been ignoring the Sequences as such, but have been working my way through the OB archives chronologically, which I gather covers the same material. 3. Hard to answer that question. The cognitive bias stuff is fairly old hat. The timeless-physics stuff is new to me, but isn't really a skill. I'm currently working my way through the metaethics stuff, which I'm not finding particularly convincing but haven't finished thinking about. 4. One friend, to both HPMoR and the OB archives. Not so much LW per se, which (sorry) seems to have a higher noise:signal ratio than the old stuff. I've been paying a little bit of attention to recent posts, but not a lot; mostly I've been "time-travelling" through the archives. I've been responding to posts here and there when I have something to say I don't see in the comments. I do this even though I don't expect anyone is reading old comments (though sometimes they get upvoted or responded to, so it's not a complete vacuum), mostly because I often don't really know what I think about something until I've tried to formulate a response to it.
0[anonymous]12y
In my observation, replies to old comments and comments on old posts frequently get a fair amount of activity. I think that many users (including myself) operate largely from the "recent comments" list, so we stand a good chance of noticing new material wherever it is.
1FrancesH12y
1. Yes 2. Reading through the Sequences. Well, I say reading through...you read through and then there's a link, and then there's another link, and another and another...So yes, reading through, but not in exact order. 3. I suppose...not necessarily have yet found useful, but am anticipating finding most useful in the future: the planning fallacy, the bit about believing the way Spinoza thought you did and not Descartes, and the conjunction falllacy. 4. Yes. And yes.
1NancyLebovitz13y
1. Yes. 2. More towards looking around and lurking, but I've been reading LW long enough that I've read a fair number of important articles. 3. I'm not sure-- to some extent, I've been working on this sort of thing anyway. I'll post later if anything comes to mind. 4. Yes to both, mostly in conversation and on my livejournal [http://www.nancylebov.livejournal.com].

I think that, in the first few chapters, Harry did not give enough credence to the hypothesis that he was simply insane and hallucinating. I think, given the observations he had at the time (his mom claimed her sister was a witch; he got a letter implying the same; a woman levitated his dad and turned into a cat), he should have at least seriously considered it. Certainly those pieces of information are some evidence for magic, but considering what that hypothesis entails — existing scientific knowledge about physics (even at the level of abstraction that we experience directly) is so completely wrong that it's actually possible to make the universe understand human words or intentions, or there's this incredibly advanced technology that looks like it's violating the laws of physics, and it's existed for thousands of years and apparently everyone has forgotten how it works — I think an honest rationalist would have to look into the "I'm cuckoo" hypothesis.

I'm not sure what one is supposed to do upon concluding that one is quite that cuckoo. Upon getting that far gone, what can you do? Can you even assume that your actions and words will leave your brain and impact reality in roughly the way you intend? If you are that crazy, and you try to walk across the room, will you get there? Are you in a room? Do you have legs? It might be that being as insane as all that is so game over that, whatever one's epistemic position is, one has to operate as though the observations were correct.

It would be a good idea to consider the hypothesis that one is crazy in a conventional way, such as schizophrenia. One can try to test that hypothesis. But the "anything goes"-crazy hypothesis isn't really useful.

5RobinZ13y
Oh, you're right - and what's more, it doesn't take much to make the "anything goes"-crazy hypothesis more ridiculous than magic. We know that human brains have limited processing power and storage capacity, so if you can produce sensations which the brain should be unable to fake, you can reduce the probability mass of the hypothesis significantly.
4DSimon12y
How can you use your brain to test if a sensation your brain is experiencing cannot be faked by your brain?
6RobinZ12y
How long would it take you to factor the number 495 967 020 337 by hand? And how long would it take you to multiply two numbers, both less than 1 300 000 [http://oeis.org/classic/a000040.txt], together? Some operations are much easier to verify than to execute.
4DSimon12y
I wrote out a long response involving an analogy to a CPU self-test program, but at the end I realised that I had arrived at the same conclusion you stated. :-) So I'm voting you up and wish to extend you an Internet high-five. However, on this topic, it seems like there's no good approach for handling the scenario where your brain messes with your internal tests in such a way as to point them invariably at a false positive, i.e. anosognosia [http://lesswrong.com/lw/20/the_apologist_and_the_revolutionary/]. I agree that a good self-test of the sort you describe would reduce the probability for most kinds of anything-goes insanity, but what sort of test could be used to check against the not-insignificant subset of insanity that specifically acts against self-tests and forces them to return false positive at the highest level?
2RobinZ12y
It's always possible to produce insane minds [http://lesswrong.com/lw/rn/no_universally_compelling_arguments/] that cannot fix themselves - the interesting question is how big a diff can be bridged at what price. And that's a bit more difficult to answer. I wonder, however, whether a sufficiently educated anosognosiac could determine that the sources informing them of their paralysis were more reliable than their firsthand observations. It seems unlikely, of course.
3rastilin12y
The answer appears to be no. There were a few articles in Scientific American: Mind about it a while back. Experiments show that the flaw causing stuff like people denying they can't move their arms is part of their logic processing; they proved this by figuring out they could reset their thinking for a short time, at which point people were able to clearly state that they were paralyzed and they were surprised at their earlier thinking. After a minute, the effect wore off and the patient returned to an earlier state. So the effect appears to short circuit the decision making process on a hardware level.
4ata13y
True. Even if upon witnessing such absurdities he had immediately assumed he was seeing things and demanded to be checked into a mental hospital, he couldn't even be sure that there was really anyone around him to hear, or that he was really saying what he thought he was saying, etc. But then, if he's that far removed from reality, whatever he's really doing must appear crazy enough to draw the attention of those around him. Maybe he's already in a mental institution... which he imagines to be a school of wizardry! From the inside, he already sort of feels (and acts) as though he's the only sane person in a madhouse... while in reality, he's just another patient.
6simplicio13y
I think David Hume said something more or less like this when discussing the likelihood of miracles; that if you witnessed a miracle, you ought to conclude you were insane. I am not sure I buy into this. For one thing, I see a problem with falsifiability. If there is nothing that I could see to convince me that magic might work, I am not objecting to the reality of magic on rational grounds, but as a sort of knee-jerk. It's like the doubleplus loony creationist types who think the devil planted archaeopteryx. There are reasons I think magic in the Harry Potter sense is not true, reasons that could be argued against (e.g., show me a plausible medium for magic to be carried in). I don't think it would be very rational to make it sort of... axiomatic that magic is false. That seems to in fact be the attitude Eliezer is criticizing in the character of Harry's father. So yeah, some probability mass goes to the "hallucination/insane" hypothesis, but not very much. Most goes to the "I don't know what's going on here at all, but she did just apparently turn into a cat" hypothesis.
1dclayh13y
Miracles are one-time events, whereas magic spells are repeatable (in every fictional universe I've seen, anyway).
6simplicio13y
True; but where does that factor come in? I mean, hallucinations can presumably be repeatable too. "I tested Monday, Tuesday, Wednesday, Thursday and Friday - and I am still Napoleon!"
5gwern10y
If he was having completely full-blown auditory, visual, and tactile hallucinations (note that this is fairly unusual, for example schizophrenia apparently usually only manifests hallucinations in one modality), then what exactly could he do about it or even how would he test it?
0ata10y
Yes, me[2010-05] did not think of that :) I agree now
4ata13y
Addenda: 1. From the reader's perspective, it doesn't appear that that's what we are supposed to believe (though I'm still wondering...), so I'm tentatively guessing that the mechanism of magic is some kind of technology, and that the in-story universe has the same laws as this one. It does seem implausible that an ancient civilization could have invented technology advanced enough to be indistinguishable from this kind of magic, but that could be different in an alternate history, and it still seems less implausible than any set of physical laws that would actually make this kind of magic a normal, natural thing that a non-industrial civilization could invent/discover. 2. We are supposed to be wondering why magic works at all, right? It doesn't seem like Eliezer to expect us to be satisfied with an Inherently Mysterious phenomenon at the center of the story, even if it's a story based on someone else's fictional world that already had that feature... but I don't know, maybe it's a demonstration that, no matter how ridiculous the rules are, rationality will still allow you to win. But I'm still hoping that magic will be explained at some point, and I'm still looking for clues about it.
3simplicio13y
I think magic will be explained as an addition onto physics: a new "force" is involved, but still behaves in an intelligible way. I can't imagine how the MoR series would explain the magic exhibited thus far as coming from current physical understanding. Unless the magicians control quantum wavefunctions directly, or something like that. Or Harry is a brain in a vat.

Or if Harry figures out that he's in a story.

1Oscar_Cunningham13y
What kind of evidence would convince you that you were in a story?

If something totally crazy seemed like it was about to happen and the world was at stake, like a technological singularity was about to occur or something, and I was called to work for the team of great minds that were trying their hardest to stop the destruction of the entire universe, dropping out of high school in the process, and meeting a beautiful girl who had been living literally a few houses down from me for the last 4 years without my knowing about it, who just so happened to be doing an essay on transhumanism for her English class and would just love to interview someone who was doing work for the Singularity Institute.

Oh wait...

9Nisan13y
The events in a story fit into a narrative. If I were in a story, I might be able to make especially accurate predictions by privileging hypotheses that make narrative sense. Dumbledore did this on an intuitive level, and it is the reason for his success.

This is basically an attempt to formalize genre savviness [http://tvtropes.org/pmwiki/pmwiki.php/Main/GenreSavvy].
1Desrtopa12y
And of course, if you really were in a story and tried it, story logic dictates that you would almost certainly end up being wrong genre savvy [http://tvtropes.org/pmwiki/pmwiki.php/Main/WrongGenreSavvy]

Then again, if your predictions are part of the narrative, the narrative might go on to explicitly falsify your predictions. And if you except it to falsify your predictions... well, two can play that game.

I'm not sure, considering the number of different kinds of story there are even in our world, and especially considering that entities which could create our world will probably have sorts of fiction we haven't thought of, and may have sorts of fiction we can't think of. However, Eliezer may come up with something which would plausibly convince Harry.
4gjm13y
I think something like "brain in a vat" is the best inference from observing magic. [EDITED to add: of course I mean after getting very good evidence against deception, insanity, etc.] More precisely: if you find evidence that something deeply embedded in the universe is best understood at something like the level of human concepts -- it matters what words you say, whether you really hate someone else as you say them, etc. -- then you should assign more probability to the hypothesis that the-universe-as-it-now-is was made, or at least heavily influenced, by someone or something with a mind (or minds) somewhat like ours. That could be a god, a graduate student in another universe with a big computer, superintelligent aliens or AIs who've messed with the fabric of reality in our part of the world, or any number of other things. In a manner of speaking this is obviously correct for the Potterverse (either Rowling's or Yudkowsky's): in that universe, magic works; and indeed that universe was designed by an intelligent being or beings, namely Rowling or Rowling+Yudkowsky. It probably doesn't work "internally" for the original Potterverse -- I've no idea whether Rowling has any particular position on whether within the stories the world should be thought of as created by intelligent beings -- but I'm guessing that it does for Eliezer's.
2JoshuaZ13y
I'm not convinced that concluding one is in a simulation is really the best bet here. A simulation would have a terrible amount of trouble specifying these effects. If for example, I have a simulation for say just our local system, how the heck are the people running the simulation easily going to be able to specify emotional states or the like? The only possible explanation I can have for this is that the simulation was originally started with humans having certain (simulated) brain structure and that structure is the type of structure that wizards have. Other humans can't do it because their structure isn't of the type the simulation recognizes to trigger magic.
2Qiaochu_Yuan10y
I agree. This is why I think the Hogwarts letter is charmed to make itself sound more plausible than it should be (which would be a sensible way to ease the transition for muggleborns). Harry explicitly wonders where his own certainty that magic is real comes from and doesn't get an answer via introspection. That sounds like the effect of a weak charm to me.
1Alicorn13y
Oh, and you're forgetting the bit where Mrs. Figg just randomly knows magic exists. That would be pretty jarring.

Several speculations/thoughts/questions:

First, did baby!Harry actually in fact survive the killing curse? ie, perhaps the curse successfully detached baby-Harry's-soul (presuming that something like "souls" exist in MoR... given the presence of Horcruxes, I'll tentatively assume yes), but the body was immediately made into a Horcrux... so Voldemort-soul-shard effectively inhabited that body. Essentially Rationalist!Harry is actually more like what Voldemort would have been like if raised in a loving and sci-fi and science loving family.

The Hat did say that if there was bits of the Dark Lord's mind there in addition to Harry, it would have noticed the extra "passenger"... But in this case there really is only one mind/soul/whatever. The catch is that mini-mort is all that's there.

This brings up the possibility of if this was an accident or deliberate. Perhaps Voldemort actually deliberately planned/faked his apparent "death"?

(Possible related, well, possibility: How do "we"/they actually know Voldemort even used the Killing Curse that night, as opposed to doing some other thing? ie, how is it known that he is the Boy Who Survived the Killing C... (read more)

4Unnamed13y
This is awesome. Probably not where the story's actually headed, but it would create a cool Vader-Skywalker kind of relationship and explain what Voldemort is trying to accomplish with Harry. If he wants his Harry-shard to finish the job of becoming Dark Lord, then it makes sense to come to Hogwarts to be Harry's mentor (and to be disgusted by Harry's ambition to be a scientist).
3CronoDAS13y
In canon, before he became Lord Voldemort, Tom Riddle demanded that Dumbledore give him the Defense Against the Dark Arts position, and the "jinx" on the position came about when Dumbledore refused. So teaching at Hogwarts is, indeed, something Voldemort has always wanted to do.
4PeterS13y
That's a good point... though if I recall, he is just known as The-Boy-Who-Lived. In canon, it's not revealed until book 4 that he is the only one to have ever survived the killing curse, in particular, and it's Znq-Rlr Zbbql who says this (though, in truth, it was Onegl Pebhpu We.). Onegl Pebhpu is a highly loyal Death Eater who had been in contact with Lord Voldemort, so maybe the dark lord just told him? Though it's probably more likely that everyone just assumed Voldemort had used his favorite curse. What bugs me is how they know that Harry is the first and only person to have ever survived that curse. I mean surely, sometime in the entire history of wizards and witches, somebody has sacrificed themself for a loved one who was then Abracadabra'd (i.e. did just what Lily did). /shrug edit: Redacted a name.
6taw13y
Wizards are far less numerous than Muggles - in world like that it's easy to be the first at something.
4Psy-Kosh13y
Oh yeah, forgot that it's not revealed until then. But given that he has the title of "The Boy Who Lived", that suggests that it's known or widely believed in the wizarding world. ie, It's not "They Boy Who Lived Through a Mild Flu", right?

I'm guessing that Blaise will shoot himself in the name of Sunshine, tying all the scores. That seems like the kind of thing Dumbledore would plot. It makes the most sense from Eliezer's point of view too, in terms of leading the story in a more interesting direction.

And I think that would make Blaise the quadruple agent, with Dumbledore as the fourth faction, and Quirrell aware of the entire thing, masterminding his own little stanford prison experiment [http://www.prisonexp.org/] in order to achieve whatever ends he's ultimately aiming for. It was interesting to see how deeply Harry got into his "General Chaos" role in this light. (Also, I think Ch. 32 was the first time I've laughed out loud over the story in a while. It was getting pretty serious and this was way more fun. The "vader/emperor voices"... I was busting up! I think this kind of hilarity at the beginning is part of why the story took off the way it did.) Plotwise, I've been wondering lately if Eliezer might be laying the groundwork for Voldemort to turn out to actually be the good guy and maybe Harry's true challenge as a protagonist will be to recognize that rationalist!Voldemort will actually turn out to be good for the world, and deserves to be supported. I could image the army lessons turning out to have a positive global outcome if they ended in the right way, which would add a bit of support to this theory.
6gwern12y
This is how one of Eliezer's early stories turned out: "The Sword of Good" [http://lesswrong.com/lw/169/the_sword_of_good/]. (There are some traces of that story in MoR - Harry early on not engaging in moral relativism is similar to the hero's final understanding of the evil of the status quo of the fantasy world. But ultimately I think Quirrelmort will be evil. Voldemort killing the entire dojo and sparing only his friend is a mortal sin and Quirrel does not exhibit the kind of heroic remorse necessary to make up for mass & serial murder. Which reminds me, we don't know who Voldemort killed to get the Horcrux on Pioneer. A security guard, probably.)

Chapter 30-31: Was there a more sophisticated basic idea than appearing to be incompetent, then playing possum? I'd have expected one of the other two armies to expend a second (double tap) sleep spell on the downed, given that Neville came up with the same tactic later on.

Also, nice touch writing Neville as Bean without using a sledgehammer on the parallel.

ETA: It took me a bit to understand Draco's particular revelation: that Quirrell made sure to place all the other smartest students (and the other candidate generals mentioned in Ch. 29) on Sunshine.

Well, Hermione wasn't just appearing to be incompetent in the sense of "too stupid to calculate the correct solution;" she was appearing to be irrational in the sense of "too self-righteous to want to calculate the correct solution."

Also, note that Hermione actually did stay true to her goals: her possum tactic allowed her to avoid "unfairly" choosing who to attack first. By waiting until most other players had been sleepified, she was able to attack only the strongest or luckiest survivors, rather than the soldiers controlled by someone that she personally disliked. She was able to both win the game and stay true to her values because she (somehow) was much better at working in groups than Draco or Harry. One wonders how a girl who had no social skills in Chapter 3 suddenly became so socially adept -- has she been reading books on how to get along with people?

7sketerpot12y
It's more that both Harry and Draco were mentally handicapped here. Draco has the glamorous dream of being the dark overlord who controls everything from the top, his orders unquestioned and his name spoken in hushed tones. Harry has the habit of trying to think up an ingenious plan by himself, and it just didn't occur to him to get other people in his army to do strategy planning. Tactics, sure, but not strategy. Hermione, in contrast, is perfectly used to learning from others, and doesn't have particularly grandiose ambitions. And maybe Quirrell casually hinted that some of the people in her army were good at planning things. It seems the sort of thing he'd do, to make his plan less brittle.
5gwern12y
As I argue in the reviews for chapter 31 [http://www.fanfiction.net/r/5782108/31/1/], Hermione herself was surely not playing possum, and likely neither were her 6 soldiers. That was not their idea. (Whether Nevile is smart enough to tell Harry, or whether one of the other armies will think of it in time for battle 2, is a question for the future.)

There were 24 people per army, and 11 of Sunshine came at Harry and 12 at Draco. And Harry & Draco had their realization of what happened when they remembered that Sunshine's soldiers went down immediately at the first shot. They were playing possum (all but Hermione, who didn't want to risk it).

The 6 soldiers left is after the battle of Sunshine's return, after they've already taken Potter hostage.

3Eliezer Yudkowsky12y
I increased the number of soldiers Hermione had left to help make this clearer.

Harry has been learning an Evil Overlord List [http://tvtropes.org/pmwiki/pmwiki.php/Main/EvilOverlordList] (warning: tv tropes), but apparently he had to figure out #13 the hard way.

Read up to Chapter 21, commenting on chapter 2. Prediction about the physics of HP:MR.

Harry is mistaken about McGonagall's transformation into a cat breaking conservation of energy; indeed, it seems to me that he is not really putting a lot of effort into finding an alternative explanation, but jumping straight to "Everything I thought I knew was wrong". (Perhaps Lord Kelvin's not the only one who gets a charge out of not knowing something; after all Harry has been wanting to do Something Big, and the more laws of physics are broken, the better!... (read more)

6cwillu13y
I think the "it's bigger on the inside" phenomenon is a better foundation to build such a spell on.
4RolfAndreassen13y
Ah yes! You can store the whole human body in a cavity of the cat's body, and vice-versa; lightspeed is no issue - indeed you could run the whole thing at ordinary neural speed. This might even solve the problem of how to order a cat's body around; the Animagus in effect has a cat as an ordinary part of her body, and has learned to operate it the same way she learned to operate her human body. One problem is the carrying-over of wounds from the animal to the human body, and vice-versa; this does not seem implied by the model, and requires additional explanation. Psycho-somatic damage? Since there a requirement for conscious control of which shape one is in, the opportunities for unconscious failure seem strong.
5RolfAndreassen13y
In fact, come to think of it, wasn't there an experiment recently with remote-controlled rats, using plain Muggle science and electrodes in their brains? Extrapolate that forward fifty years and add those direct-to-brain conputer interfaces, and we could do something rather similar, given lots of training to get the feedback right. "When I think like this the rat goes that way..." An Animagus might learn this almost as a child learns to control its body.
2Blueberry13y
Switching the material still violates conservation of energy. You could make a perpetual motion machine by creating a heat engine and switching hot water with cold water located elsewhere on the planet, for instance.
7Baughn13y
Without external input such a machine would eventually make the entire planet lukewarm, and run out of steam. No violation there. You're also assuming that the switching doesn't require energy.
2Blueberry13y
Yeah, you're right, that that would just increase entropy faster. But what about using gravity to get the hot air or water to rise? Hmm. If the switching requires no energy, it still seems like something is violated, but I'm not sure I know enough physics to determine what. What about conservation of momentum? Do the switched objects keep their current acceleration and speed?
2Baughn13y
The concept of switching in itself violates all kinds of fundamental assumptions in physics, so trying to think about it mostly results in nonsense. That's if the switch doesn't actually involve moving A to B and B to A by some path, though; if it does, you naturally pay the relevant costs to maintain conservation laws while switching.
1RobinZ13y
Still FTL, but that's a violation that's turned up explicitly many times already.
6RolfAndreassen13y
It doesn't have to be FTL. You could store the cat body in Magical Britain and run the communications link at lightspeed. It would look instant to a human - the speed of neuron processing would still be the bottleneck.
7Psy-Kosh13y
Although, given that there's already stuff like time turners, it's kinda a bit late in the game to be worried about FTL.
1RobinZ13y
You're right - and the speed-of-light delay in a straight line even through the diameter of the earth is only 42.55 milliseconds. That might be small enough not to be noticed.
1[anonymous]13y
Though through the diameter of the earth is not an easy way to transmit messages.
1ShardPhoenix13y
Neutrinos! However by the time you're postulating teleportation and time travel and so forth, I don't think it's necessary to insist on (obvious) conservation of energy in the first place.
1RobinZ13y
Taking a great circle route increases lightspeed time to approximately 66.8 milliseconds. That might still be small enough to miss if you're teleoperating from Britain a body in New Zealand, but it's pushing the boundary. Wikipedia suggests 50 milliseconds [http://en.wikipedia.org/wiki/Latency\_(engineering\] #Latency_in_simulators_and_simulation).
1dclayh13y
Getting light to follow the curvature of the Earth without a fiber-optic cable or some other specialized medium seems difficult. Probably better to go straight through and just use a wavelength to which the Earth is transparent. Of course the Muggle solution is a network of satellites...

I really enjoyed the series and hope it continues. I have a few comments.

Eliezer had already stated that one intention of his was to make writing fun again, while writing his rationality book. Hence, I guess once that boost is achieved, this litlle jewel will probably lie around unattended for a while.

If the other, more important, purpose was to raise the sanity waterline, then regular updates might be expected as this would be a serious attempt at reaching people through other means.

5Unnamed13y
I think any big contributions are likely to come from HPMoR readers who are attracted to LW, become a part of this community, and then go on to do good stuff. HPMoR is just the gateway drug. Then there's the more diffuse sanity waterline effect of lots of HPMoR readers becoming somewhat more rational, and more receptive to big important ideas wherever they encounter them. Sci-fi has had that kind of effect on the development of a lot of people here, and this story can extend that kind of influence to a new audience via Harry Potter. Plus, in this case Eliezer got to fill the story with the ideas and themes that he considers most important.

The idea of promoting Less Wrong (and rationality in general) via Harry Potter fanfiction is so outside the box that I really shouldn't be surprised that it exists! What a great way to tap into a particular group of people that may not have necessarily found their way here otherwise. I wonder if we'll get any users to come out of the woodwork and say they've found LW through the fanfic?

I hope we see more projects like this (from anybody here) in the future!

wave Hello! Brand new, just discovered the site through the fanfic, and still in the looking-around stage... but yes, it does work.

It definitely helps that it is totally frelling awesome fanfic. Admittedly, I'm biased; I'm writing a Potter live-action role-playing game one of whose goals is to figure out how the heck that tacked-together universe could possibly make sense, and what would explain the observed evidence... ;)

It's already happened - I don't have a link, but I've seen at least one comment to that effect.

I can also report that I have at least two friends who started reading the sequences after encountering HPMR.

Here's what I think will happen:

Zabini stuns himself in the name of Sunshine to create a tie. And here's why:

1) The rest of the school is very partisan about their favorite army, so it's not likely that many are betting on a tie. Zabini (through a proxy or otherwise) put all of his chips on "tie." So he will return to Hell a much richer Prince of Darkness.

1[anonymous]12y
Predictions? Regarding the note of confusion Harry feels in Chapter 3: the Killing Curse "strikes directly at the soul", but in Voldemort's case it burned his body. More likely he never cast it at Harry Potter, and the burnt hulk they found wasn't him. He learned about the prophecy and, being smart, changed his plans rather than risk fulfilling it. And the Source of Magic is a UFAI that optimizes the world into stories. I hope all my predictions turn out wrong. What I want most from this story is to go on being surprised.

Another point in chapter 32 that could use some explaining: Why are Harry, Draco, Hermione the only ones in the running for the Christmas wish? Do Quirrell points from battles tend heavily towards the generals? (Though I guess they were all doing especially well in the class anyway...) That, and there's only one Christmas wish, for all seven years; obviously the other years are a bit outside the scope of the story, but with no explanation it still seems a bit strange that noone from those years would even come close.

Yes, that was stated in a previous chapter.

Chapter one, when Petunia is talking about how she wanted Lily to use magic to make her prettier:

"And Lily would tell me no, and make up the most ridiculous excuses, like the world would end if she were nice to her sister, or a centaur told her not to - the most ridiculous things, and I hated her for it.

Chapter 28: I wonder what happens if Harry realizes he's living in fiction, and everything he's dealing with is made of concepts rather than atoms.

Which leads me to think about the people who say that if they found they were living in a simulation, they'd try to get out. Unless the simulation is very similar to the substrate, would it be possible to get out while remaining yourself in any sense?

7red7512y
It will be weak move on Eliezer's part. As it will effectively make him the god of Harry's universe, which mean that Harry's universe cannot exist without him, that it is not self-sufficient and self-contained.
5gwern12y
Sure. Escape into another simulation. More seriously, obviously it's not guaranteed that an organism in a simulation can just create a copy in the outside world. How would a Game of Life organism, made out of glider guns and flashers and whatnot, made an atom-based form of itself? What it could do is create something isomorphic. Whether this is possible is pretty much the same question as whether humans can make uploads. (Which is the inverse, actually - going from 'reality' to 'simulation'.)
4NancyLebovitz12y
Alternatively, you keep living in your simulation, but you get enough of a handle on the substrate that you can make changes in your simulation, protect it, or duplicate it.

Absolutely. It'll just take a superintelligence and some nano-tech.

3wedrifid12y
And this seems to be exactly what Dumbledore himself does. That is a lesson I hope we see Harry take on board for future experiments.
1wedrifid12y
An interesting thought... I think Harry should actually be pleased with that discovery. Given everything he knows about fictional realities and his observations thus far about the HP universe he should be more confident in his ability to achieve godhood. DND is a system that has gone through versions, with a strong motivation for making it ungamable, but there are still loopholes.

Since around Chapter 20 this is actually my guess for the entire basis of magic that Eliezer is working from. That is... there's a jumble of ideas and tropes that are invented and sequentially stolen by one author after another. Someone tells stories of Vlad Tepis, Bram Stoker comes along... and N iterations later you've got Twilight with vampires having extra chromosomes and clairvoyance.

To understand a magical universe at the deepest level is to see the hands of previous authors influencing your physics and history (and possibly your future if you are in a prequel) plus a "current author" who has a measure of finer grained control over things like plotting and characterization - limited by the audience's willingness to play along.

If this theory of magic is right, rationality in a magical universe should lead you to to become genre-aware, and then the next obvious(?) thing is to go meta genre-aware and start trying to "genre hack" your universe and see if you can "tunnel" into the derivative works (or maybe just get the author to fall in love with you or something).

My current working theory is that Dumbledore as figured out a rough outline of these ... (read more)

Yes, well, you may have to write yourself the work you always wanted to read.
6JenniferRM12y
Cryptic, with a dash of sass :-) Is that a denial plus an exhortation to write it myself? Or is it a smug admission that you're writing what you wanted to read which is something in the ballpark of my guess? I'm also curious if you have plans to bootstrap out of our present situation? I've run some minor "metaphysical experiments" in the past to see if the world is as strictly "object level" as it seems to be, and I've recently tried a couple micro tests inspired by your HP story to see if "this world's story has started yet" with me as a character who can break the fourth wall and get feedback, and so far they've all come back with boring results.

You'd probably enjoy "Sophie's World" and "Godel, Escher, Bach" if you haven't already read them. (One of the dialogues in GEB features pushing-potion and popping-tonic; pushing-potion moves you down a level into a work of fiction or art, and popping-tonic takes you back up a level.)

I like your explanation, because it seems that the logical endpoint of your hypothesis would be my prediction [http://lesswrong.com/lw/20w/open_thread_april_2010/1uiq] that rationalist!Harry becomes Harry in the universe of the The Finale of the Ultimate Meta Mega Crossover [http://www.fanfiction.net/s/5389450/1/The_Finale_of_the_Ultimate_Meta_Mega_Crossover] . If you have not read The Ultimate Meta Mega Crossover, you probably should, because it is genre-aware of its genre awareness, maybe a few more levels of meta-ness, or that kind of infinitely recursive meta-ness of this kind of selfawareness taken to the insane logical conclusions. The spoilers for Permutation City are total -- Meta Mega Crossover contains an explanation of the ending of Permutation City. The Fire Upon the Deep spoilers aren't nearly as complete.

0JoshuaZ12y
It was strongly implied that Snape is familiar with Lord of the Rings to the point where he recognizes what the word "Nazgul" means. And it also is implied that Snape finds Harry comparing him to a Nazgul to be amusing. If Snape knew he was in a fictional work I doubt he'd find this as funny.
2EStokes12y
Wouldn't he just be amused that Harry's got it wrong?
0Strange712y
Chapter 28 aftermath 2 could be considered evidence in support of that hypothesis.
1Blueberry12y
Wait, how? I didn't fully understand the implications of the end of chapter 28 and aftermath 2, but it seems that Harry's discussion with Snape has changed Snape in some strange way (hence his comment to Dumbledore), and the aftermath was evidence of this change, the new Snape now turning down students going after him.
3Eliezer Yudkowsky12y
Okay, if no one on LW got Aftermath 2, even after working out that the aftermath was supposed to display a change in Snape, then it was too subtle.

My hypothesis is that thus far he's considered poor Alissa to be the most inconsequential thing ever to intrude on his thoughts; and having thought more deeply about what happened with him, Lily, and James when he was a kid, he now decides he ought to her to nip her affections in the bud for clearly stated reasons, rather than letting them fester without suitable closure for, perhaps, an unduly long time as his have. His only closure was that he insulted Lily and felt guilty about it forever (as apparently, from his perspective, this was the only thing standing between him and getting to be with Lily); Alissa's could be the end of school, without the issue ever being directly addressed.

The problem with this hypothesis is that it has Snape thinking that student crushes on teachers are persistent sorts of things, and this isn't typically the case.

3Sniffnoy12y
Well, he could well be generalizing from one example [http://lesswrong.com/lw/dr/generalizing_from_one_example/]...
2red7512y
How do you interpret emphasis on "bad idea" here? It doesn't seem to fit in "more care from prof. Snape" hypothesis.
3Alicorn12y
The part of her that wants to do that is the part that's fantasizing about special detentions; the instinct that says "bad idea" is the part that doesn't think this is one of those.
0red7512y
Ok. I should think about it.
1Alicorn12y
No, I had it mixed up before. It is fixed now.
1erratio12y
That seems a little too compassionate for any version of Snape My own take is that he's finally realised what an idiot he was for crushing so hard on Lily despite her lack of reciprocation. He's now being extra harsh on Alissa as a kind of substitute for going back in time and telling his younger self to get over it.

Will we get a hint?

Well... we don't have much of a baseline to compare this version of Snape to.

8pjeby12y
Yes, but what part was the change? That he dislikes student affections? That he tells them about it? That they have affections? That he's previously been taking advantage of students in slashy ways? If anything, I would've expected it to be him actually taking advantage, if he were taking Harry's advice to... oh. Wait. Maybe he is taking Harry's advice and has started looking for deep instead of pretty? If so, it was definitely too subtle. ;-)
2Eliezer Yudkowsky12y
I'm getting a pretty sharp lesson in unintended ambiguity here. Although some of your suggestions are not compatible with a straight reading of the text.
7jimrandomh12y
Given the number of theories so far, I'm surprised no one has suggested this one: Aftermath 2 is in fact meant to demonstrate that Snape's behavior has not changed, by displaying behavior that is entirely typical and expected of him; but now that Harry, Minerva, Dumbledore and the readers are all primed to look for changes, they will find them even where they shouldn't.
6Nisan12y
Whatever it is, it must have something to do with this:
5orthonormal12y
He may have had his mental discipline upset by the events of the previous chapter, causing him to be less in control of his Legilimency in some fashion. I did note the significance of the command to "restrain your eyes henceforth". But yeah, even if I'm on the right track I don't feel confident of it. Too subtle for this reader.
5Blueberry12y
Harry told Snape that Lily only liked James because of his money and looks. So is it that Snape now thinks his students only like him because of his position and power, whereas before he thought they liked him for who he was? Has he become even more cynical? More inclined to reject people? ETA: Some reviewers thought it was a reference to Snape performing Legilimency, but of course it doesn't take a mind reader to notice a dreamy-eyed girl.
5Tyrrell_McAllister12y
This is what I figured. And there was the comment by Dumbledore (or Minerva?) that Snape wouldn't hurt Harry because Snape loves Harry's mother. So I'm now assuming that Harry managed to convince Snape that Harry's mother is not love-worthy, which means that Harry is now stripped of that protection.
2[anonymous]12y
He tells her to stop staring at him, and doesn't look at her when she comes to see him after class. Perhaps this was because he no longer needs to read her mind, because he's decided to stop reading students' minds, because he was doing so at the headmaster's bidding and he's broken with Dumbledore. Wildly conjunctive and supported by a hair's breadth of evidence, but I don't have a better guess. Nothing else seems likely to have a dramatic effect on Harry's story.
3Psy-Kosh12y
Hrm... So far best I can come up with are two possibilities, one more charitable and one less charitable toward Snape: First: From his conversation with Harry, he perhaps concludes that making one's feelings (or lack theirof) to someone that may have feelings for you absolutely clear rather than leaving it ambiguous may be a good idea. (ie, in his own way, he wanted to protect his student from ending up in a situation similar to himself) Second: He was sufficiently POed at Harry that he's no longer keeping his agreement to not legilimens the students. I'm not really assigning all that high credence to either of those hypotheses, but they're more or less all I could come up with so far. So... give us a hint? :)
3red7512y
Analysis of Harry's conversation with Snape in ch. 27. Possible Snape thoughts: "He implies that I wasn't even a friend of She. How dare he!?" ... consideration of different ways of mutilation ... then "Oh! He can't possibly be like his mother. She had a very high standards for Her friends. Maybe his stepparents taught him this indiscrimination of friends." "SHE was shallow!? ... But She married that brat Potter. Was Her standards high after all? Maybe not. And I gave all the power I could have for her..." So I think Snape became misogynous. Thus Alissa's affection became irritating for him. I don't know what implications it will have for storyline however. Edit: Analysis is done by Type 1 processing with Type 2 postselection, so no justification is given. :) Edit: This hypothesis seems to be insufficient for explanation of emphasis on "wrong" in Aftermath 2, maybe there's something more. Edit: 1. "Wrong" can mean, that she was aware, that Snape isn't kind of person young woman is supposed to crush on. I'm not sure that this is true for Slytherin. Anyway Snape isn't handsome guy, it's not deserve emphasis to hint that. 2. "Wrong" can mean, that she feels it's bad for her to show affection now. Fits my hypothesis, but not wording "There was probably something really wrong with her...", which imply that she knew it all the way. Some part of puzzle seems to be missing.
6pjeby12y
The "wrong" is presumably that the wizarding world isn't much familiar with, or accepting of, urges tending towards BDSM. A student of her age would be unlikely to be familiar with the idea of such a thing not being "wrong", given their lack of internet access. ;-)
1red7512y
Um, yes, I find out what special detentions mean after I wrote last part.
2DanielVarga12y
My interpretation was that he gets a kick out of giving students love potions, reading their minds for kinky thoughts, and then refusing them in a humiliating way. It's a sort of safe sex. Obviously, this is not what you had in mind, as this has nothing to do with changing.
6JoshuaZ12y
It seems like both you and Gabriel (below) have constructed hypotheses which make sense in isolation from certain relevant facts. In particular, there's a large fraction of the HP fanfic world consisting of females who write things with BDSM aspects and a dominant professor Snape. For example a dominant Snape with submissive Hermione pairing is not uncommon. Presumably whatever is going on here is in part making fun of that segment of fandom. (I dated a girl at one point who's very much involved in the HP fanfic community and might not have picked up on this point otherwise. ) If not for Eliezer's remarks that there was something serious in this section I'd think that that was all that was going on this section- just a Take-That! [http://tvtropes.org/pmwiki/pmwiki.php/Main/TakeThat] to the fanbase. Given Eliezer's remarks I think he intended it to be both a Take That and also something else possibly along the lines of Alicorn's hypothesis.
3CronoDAS12y
Yes, I too thought it was just a cheap joke at the expense of Snape/student fanfiction...
2gwern12y
I actually took it for Snape venting and doing a little dogkicking [http://tvtropes.org/pmwiki/pmwiki.php/Main/KickTheDog]; so yes, I guess it was too subtle. (It seemed too abrupt and cruel to reflect any good change in Snape.)

In absolute terms, it was abrupt and cruel. But by Snape's standards, it was remarkably civilized. He didn't humiliate her in front of the whole class, and he ended it quickly.
3gwern12y
That makes sense, I suppose (although I must have too high standards - it would never have occurred to me that this was a step up). I wish we had more background on how Snape treated student crushes.
2topynate12y
Given that it was called 'Aftermath', I knew it signified some change, but in what direction I don't know. My best guess is that he's not romanticising crushes anymore. So in other words, this is actually a positive change for him.
2NancyLebovitz12y
My actual interpretation was that he'd let his shields down enough that someone could find him attractive.

Ever since the start of this year she'd been having trouble listening in Potions.

This don't mix very well with your hypothesis.

3NancyLebovitz12y
Good point.
4wedrifid12y
Or, disillusionment with the one girl he found attractive has finally pushed him out of the closet.
1major12y
I don't know about subtle. I noticed it on my second read. Why call it Aftermath 2? Why not just a nameless block? How is it the result of anything? I guess I didn't fail to notice my confusion. Dumbledore messed with the girl's mind to test if Snape was still in love with Lilly. What I'm a bit uncertain about is the 'Ever since the start of this year' part. Has he been setting something like this up every year to have something ready when needed? More like, was that an intended implication? Mind, the second part only occured to me after I read the reviews re Ch29 Notes.

Hm, he did take sexual advantage of the student and then, being far above the 11-year-old-Draco-Malfoy lower bound on villain cunning, altered her memory?

0NancyLebovitz12y
I think you underestimate Harry's will to power. He was working on a cure for Alzheimer's, but are there really people with Alzheimer's in his home universe? As many as there are here?
0wedrifid12y
As far as we know, exactly the same number. But I took the "Alhimer's cure" to just be a test for an obvious exploit in the form of something that would appeal to Hermione and with approximately the desired complexity. Hang on, what which comment are you replying to here? I had assumed you were talking about questioning Harry's judgement (ie. overconfidence) regarding using Draco. But are you thinking that a concept based world has less potential for godlike power gain than a reductionist one?
2NancyLebovitz12y
I think Harry would want to have power where it could make the most difference. His ideal outcome would probably include using his magical powers to get results which can be applied in both worlds, even if his effects are less godlike out here.
0wedrifid12y
I think we must be talking about something different. I thought Harry was only in one world.
2NancyLebovitz12y
I'm heading off into wild hypothesis land. If Harry figured out that he was living in fiction, what would he want to do?
1wedrifid12y
Ahh, gotcha. And from what I can tell Harry would want to get results in both worlds. In fact, he would quickly begin to consider this world to be 'his'. It is similar to the kind of thinking he did when tranfiguring. From cognitive maps through molecules and atoms down to quantum configuration space. Just another step further. I would expect him to consider you and I with exactly the same priority as similar individuals that share his fictional emulation. Now, as for what he can do to influence our world... that's an interesting thought. Create a superintelligence and solve the AI Box problem with the added difficulty of having to explain to the outside world how to build the AI structure. It is not inconceivable (but still unlikely) that the 'author' or emulator does not, in fact, know how to build a superintelligence himself. It is possible to be able to create a fictional world with someone like Harry in it while naturally being an inferior (but faster) thinker. Say Harry found out that he was living in fiction and in the process of updating raises the probability that he can achieve godhood in his fictional universe but assigns a far lower chance to significantly influencing the base world. Would Harry be pleased or displeased by this discovery? My guess: He'd be all distraught and angsty about it. But I think that is due to him having immature emotional responses. He is, I suggest, strictly better off in the newly discovered situation than in his original scheme.
2bogdanb12y
I’m not quite sure that passing through cognitive maps, then molecules, then quantum configuration space, then timeless quantum mechanics, and then concepts in the mind of his pseudo-world ’s author quite makes sense as progression. “Seeing-through” the successive “layers of the world” helping transfiguration might make some sense in a fictional world. (Though I have a bit of trouble with why exactly only the extremes, i.e. conceptual and then timeless physics, do something interesting, rather than the intermediate steps also doing new things.) I doesn’t quite make sense when considering all those layers knowingly imaginary layers above the conceptual level of the author’s mind.
0Baughn12y
Whatever his writer wants him to? I'm uncertain in which sense someone could be said to figure that out and still have a will of their own. It's a bit beyond merely living in a simulation.

If 'free will' is compatible with physical determinism (including the quantum variety) then why can it not be similarly compatible with living in a world based on some guy's thoughts? The same principles seem to apply.

9gwern12y
I think the problem is a lack of detail. Harry isn't being simulated down to the neuronal level, or even down to the brain region. 'He' is a loose set of rules and free-floating ideas that please Eliezer or survived his theories, a very small entity indeed. And the rest of his world is even more impoverished - the rest of the world may just be a few words like 'the rest of the world'. Harry can't even execute bounded loops unless Eliezer feels like formulating them and actually executing them. If Harry discovered he were in fiction, his motivation to help the rest of the world would instantly vanish. In fact, the most moral thing he could do is to hide in his trunk forever - if a rape only happens when you go to rescue the rapee and the narration follows you, if the murders only happen because you went looking for murders, then out of sight, out of mind, out of reality. In a 'real' simulation, this would not be the case, even if the author would never permit a character to test this. (He might still want to escape into our world if the author desires him to desire this, but help his world? His world can no more be helped than J.K Rowling can help Zanzibar in canon HP. There is no there there.)
9NancyLebovitz12y
I think fictional characters can be more than that. I don't know how Eliezar experiences Harry, but some authors talk about their characters talking back to them, or resisting some plot twists. This suggests to me that some characters are similar to full human self-images, though with less memories.
7cousin_it12y
Haha, so Harry can "truly escape" by means of Eliezer going mad and imagining himself to be the escaped Harry. Or maybe they could time-share.
7Baughn12y
I believe I'm speaking for all of us in stating that I hope he isn't aiming for that end. ;)
0Kevin12y
I think that kind of thing might have to wait until Harry is 15. I'll be surprised if there isn't a many year skip ahead in the next 25 chapters of the story.

Chapters 25 & 26

Quirrell is cold. It looks like he gave Rita Skeeter a tip that something would be happening in Mary's Room so that she'd go there as a beetle and he could (literally) crush her. Is Harry going to start to figure him out (like he did with Draco after his reaction to that other newspaper headline)?

Also, does anyone know if Q/V's habit of whistling/humming a tune (appearing in both chp. 25 & 26) is based on something in canon? It sounds like a tell, when his plotting against Skeeter/Potter is going according to plan, but I'm wondering if there's anything more to it.

3[anonymous]12y
I don't know about the canon, but the narrator calls it a 'small tune' or 'little tune', so I'd guess it's the Little Fugue in G Minor which Eliezer's mentioned several times here.
6Blueberry12y
You don't think it's a canon?
8gwern12y
In fanfiction? Not likely.
2pjeby12y
Perhaps it's Pachelbel's canon in D [http://www.youtube.com/watch?v=JdxkVQy7QLM#t=2m6s]. ;-)
2Eliezer Yudkowsky12y
...I am not sure if Professor Quirrell whistles Bach. I shall have to think about it.
3[anonymous]12y
The idea appealed to me because it meant you were protesting that the villain was not an author mouthpiece at the same time as he was whistling your favourite piece of music while contemplating murder. As an act of contrariness, it would've been of a kind with writing "colder than zero Kelvin" [http://www.fanfiction.net/s/5782108/18/Harry_Potter_and_the_Methods_of_Rationality] when you were still arguing with the reviewers who didn't get the "divided by zero" joke.

If you were Harry and were trying to get from "how the hell does magic work" to "omnipotent lord of the universe" what would you do?

I think my first step would be to learn how people go about inventing spells.

I would take Rick Cook's approach - look for meta-spells and figure out how to combine them into something Turing-complete. From canon, we already know that spells can operate on spells ('priori incantatem' or something like that), and I'm almost sure that some spells do logical operations.

If that doesn't work out, start making the Philosopher's Stone. I will know that it's possible, and that's half the battle. Once I have the Stone, then the question of 'fastest method to omnipotence' loses its urgency.

(If this is simply not possible for a 1st Year, then I will set my sights lower on the felix/luck potion; Harry has enough money to finance all the ingredients he could possibly waste, and once you have a vat of luck potion, you can spend it on research in the library, random generation of possible recipes, or direct attempts at creating the Stone.)

Really, you should use it to try to discover a more powerful luck potion, then take the more powerful luck potion to try to discover a more powerful luck potion still, until eventually you get a hard-takeoff scenario where ever-more-powerful luck potions are falling from the sky into your hands by pure chance every second.

After the luck-ularity, Harry can just throw a random rock up in the air, and it will hit Lord Voldemort right between the eyes, killing him instantly at the same time the Pioneer probe crashes into an asteroid.

9novalis12y
You are assuming that the luck from a luck potion tracks the drinker's extrapolated volition, rather than just the luck potion's inventor's idea of a Nice Thing to Happen. After all, you would rather not win the Quiddich match, if doing so would lead to your defeated opponent dropping out of art school to go hang out in beer halls [http://en.wikipedia.org/wiki/Beer_Hall_Putsch]. I guess MOR's Harry hasn't realized this yet, but readers of Less Wrong should.
9gwern13y
That's already taken care of; if it's luckier to discover a luckier luck potion than the Philosopher's Stone, then that's what I would discover. And of course, by induction, then subsequent consumption will result in even luckier potions (since luck presumably compounds so any subsequent improvements will still be luckier than a PS's discovery). If there is no luckier potion or the Luckularity would hit a plateau, then I would be better off with the PS and hence the luck and preference would line up. So seeking the PS is the dominant strategy.
1red7512y
We've seen what happened when Harry tried to invoke Infinite Processing Power spell. It's plausible to assume, that each hard-takeoff setup will fail spectacularly. For example, Harry will get enough luck to enter nirvana.
2gwern12y
You say that like becoming a bodhisattva is a bad thing. 'I vow to save all sentient beings...'
2RichardKennaway12y
A bodhisattva is someone who deliberately refrains from departing into nirvana, but stays behind in order to save all sentient beings.
2gwern12y
A nitpick essential to my joke - having enough luck to enter nirvana is not the same thing as actually entering nirvana.
1red7512y
Bad thing? I can't see the implication. It's hard to imagine that peaceful mind will still be trying to hack magic even for saving all sentient beings, thus it's a failure of sorts. Does that failure imply badness? I don't think so.
1gwern12y
Indeed?
-1red7512y
Do you want to say that "fail spectacularly" has connotations I'm not aware of? I intended it to mean "fail in unpredictable and confusing way". I'm still puzzled by your reaction. Thanks, I've corrected typo.
8NancyLebovitz13y
I would look into magic detection spells and see what I could find out about magic from them-- not just studying the spells themselves, but also see if there are subtle things about magic (does it come from somewhere, how fast does it happen) which offer clues about its nature. Also, can magic be used to increase magic? Follow that with careful thought about the implications of a magical singularity.
0[anonymous]13y
Pretty much what he's trying to do: Figure out what magic is and how it fits with the rest of reality. That understanding is bound to bring up a few shortcuts to ultimate power. The difference is that I'd be more focused and more secretive. V jbhyqa'g jnfgr gvzr nggrzcgvat gb 'ghea' Qenpb, sbe vafgnapr, naq V jbhyqa'g unir gbyq Dhveeryy nobhg zl nzovgvba.

There's been some speculation on what a +4 spoon would do, so I figured I'd weigh in as an expert of sorts on D&D.

Really, it depends upon what it's being enchanted for. I think the default assumption is that it's enchanted as a melee weapon, and so functions as a diminutive one-handed weapon that does 1d2+4 damage - given the strength of such creatures, you're probably looking at 1d2 damage after the strength penalty, which is a modest improvement over the 1d2-4 (minimum 1) an unenchanted spoon would get you, for the reasonable price of 32,300 gold pi... (read more)

7jimrandomh13y
It gives a +4 bonus to the dexterity check to avoid dropping ice cream on your clothes, or others' clothes. However, due to a quantization issue in the laws of physics, exactly one-twentieth of all scoops still result in critical failures, and many of those failures lead to food fights, which is where the +4 to hit and damage comes in.
3Alicorn13y
Don't be silly, it's just a bonus to Craft (cooking) or Profession (chef).
1JoshuaZ13y
Does a dex check have a critical failure on a 1? I think that applies only to saves and attack rolls. Skill checks don't suffer that problem and I think the same rule applies to flat ability checks. (I'm going off the 3.5 rules here, I seem to remember when critical failures occur was slightly different in 3.0 which may be relevant here)
2thomblake13y
Of course not.
2JoshuaZ13y
I'm not sure most people have the rules so intimately understood that they would think the "of course" in "of course not" deserved to be there. This may be related to understanding degrees of inferential distance.
1thomblake13y
Yes, that was the joke.
3JoshuaZ13y
Ah, in that case, I must spend too much time on the Giants in the Playground Forum where a statement like that would seem perfectly natural.
0JoshuaZ13y
Would the +4 also go to the attack roll not just the damage roll?
4Alicorn13y
Yes, but it won't stack with the enhancement bonus for masterwork, if it's a weapon. Incidentally, these bonuses do stack on at least some skill enhancement items, like musical instruments, because they give different bonuses ("circumstance" and "competence", IIRC).
0JoshuaZ13y
Right, but the masterwork enhancement is just +1.
0Alicorn13y
For instruments it's +2.

From reading it, I got a sense that Eliezer actually has something in mind on how magic works in the story. That would be mindblowing because it would have to be a consistent explanation how magic works, how magicians got to use it, why they loose power over time. And why no physicists stumbled over it by accident.

Is that a shared idea, or am I the only one?

1kybernetikos12y
There's a fairly obvious answer to that stuff in my opinion. Ventus by Schroeder (scifi) covers it nicely. It would be a structure set up by the atlantians for control of nature, before they ascended probably and left Earth for the stars. Edit: It occurs to me that the other possibility would be a simulation, originally invented by the atlantians for them to upload themselves into, or perhaps muggles were supposed to be NPCs.

Thank you. At first glance I thought that I would be disappointed with that solution. But after reading the Ventus Plot description it sounded pretty neat.

See Larry Niven's "The Magic Goes Away [http://en.wikipedia.org/wiki/The_Magic_Goes_Away]" universe. He does not seem to have worked out "particle physics with magic" to explain how to cast spells exactly, but he does have a universe that makes more logical sense in terms of economics and sociology and so on. Basically all atoms in his universe had an aura of mana which functioned as a non-renewable source of "magical energy" for "everything magical you've ever heard about". Some magic can also be gimmicked out of events with emotional resonance to recharge nearby atoms but not very much, and most really huge emotions happen because of personal loss, so there is still an implicit sort of "third law of magic dynamics" at work relative to any magic that's worth acquiring. The reason physicists haven't discovered it is that there's basically none left.

May I suggest "third law of thaumodynamics"?

4MartinB13y
So far many chapters managed to up the ante. Meaning there is way more depth than i expected initially. The story wouldnt loose much if there is no magic explanation, but well. it would be mind blowing if there is. And of course Harry will research till he hits the solution or a dead end. I made up a few trivial sounding solutions for all the patterns shown in the story (trivial for LW/OB readers) but do not want to invite too much speculation. Another thing I really liked was the depth of characterization. Usually in SF thats not too well done. Here the nice old teacher lady, Dumbledore, Harry, Hermione and so on all appear as full characters with strengths, weaknesses, insecurities and motivation. Looking forward for the next chapters!

I found this series much harder to enjoy than Eliezer's other works -- for example the Super Happy People story, the Brennan stories, or the Sword of Good story.

I think the issue was that Harry was constantly, perpetually, invariably reacting to everything with shock and outrage. It got... tiresome.

At first, before I knew who the author was, I put this down to simple bad writing. Comments in Chapter 6 suggest that maybe Harry has some severe psychological issues, and that he's deliberately being written as obnoxious and hyperactive in order to meet plot... (read more)

I think the issue was that Harry was constantly, perpetually, invariably reacting to everything with shock and outrage. It got... tiresome.

I suspect that a main inspiration for writing the story was Eliezer's constant shock and outrage over the fact that Rowling's characters show absolutely no interest in the inner workings of their weird Universe. I vividly remember how outrageous this was for me when I read the originals. Actually, I have only read the first two books, so when I read Eliezer's time-turner scene, I first believed that he invented the artifact and the situation as an over-the-top satire of this phenomenon. Giving young children time-machines so they could attend more classes, yeah right. When I figured out that the whole scene is almost literally copied from the original books, I screamed in shock and outrage just like rationalist Harry did.

Literally laughing out loud, here.

But just to be clear, this story represents my outrage at all scientifically uncurious characters everywhere, and even more than that, my unfilled need to read a story where for just once the alleged "genius" characters are actual geniuses.

I was not picking on J. K. Rowling in particular in any way.

It is a work of Harry Potter fanfiction for the following simple reason:

I knew I needed a rapid feedback loop to motivate my brain to write. That was why I was bogging down on the rationality book.

And to the best of my knowledge of the entire world of online fiction, if you were posting an incomplete story chapter-by-chapter, it would get the most reviews if...

...it were a work of Harry Potter fanfiction posted on fanfiction.net.

QED.

I think I know a place on the internet where you can post books on rationality chapter-by-chapter, and get much instant feedback.

Actually, on reviewing this remark later, it's not quite true. My brain generated an idea set in the HPverse because I'd been reading a lot of HP fanfiction, and I accepted it and stopped the search because it was also optimal for getting reviews. However, I've since read analyses showing that Twilight stories are getting more new reviews on FF.net than Harry Potter, and I don't think I'd have been the smallest bit tempted if I'd known the fact in advance.

I think a version of Twilight with a rationalist Bella as the protagonist would be hilarious.

It'd also be very short, though.

You should totally write one!

I'm tempted! And come to think of it, I suppose it wouldn't have to be short; I could draw it out by leaning on the right bits of canon...

But I loaned out my copy of the first book ages ago and it's still gone, so I would need to pirate a copy as reference.

5Blueberry12y
Hopefully Bella can join up with a few other vampires and start taking over the world. It could be very long. Sent.

All right, all right, I'll at least give this a try. In keeping with the books' title themes, what do folks think of "Luminosity" as a title? (With luminosity as a theme over HP:MOR's emphasis on science, because I don't have the background to competently pull off the science.)

I did it.

Also, I hate fanfiction.net's interface for publishing stories SO MUCH. I'm probably going to just put the rest of this on my own webspace. EDIT: I am still updating on ff.net to get readers from conventional Twilight fandom, but made the story its own website and have changed the link above.

Also-also, my only account on fanfiction.net is Alicorn24. I am not affiliated in any way with anyone else using the word "alicorn" in their username.

Also-also-also, I'm not quite as much of a review junkie as Eliezer is. However, I a) am unlikely to bother with the story if I'm the only one enjoying it, as I do have creative projects with audiences that could benefit from my attention, and b) plan to treat this as a somewhat experimental work. (For instance, the first chapter has no actual in-quotes dialogue, which I did because dialogue is my strongest suit as a writer and it was challenging to work without it.) Info on what works for readers and what doesn't would be good, as well as periodic reminders that someone's paying attention.

6RobinZ12y
Interesting. You might want to revise the description a couple chapters in, once the story has its own identity, but the character seems like someone who might be entertaining to follow. (As with Harry Potter, I'm coming in with zero knowledge of the base material - Twilight bored me no less quickly than Philosopher's Stone.)

New chapter. [http://www.fanfiction.net/s/6137139/3/] I think I'm going to update daily for a while, but no promises. I'm having trouble making Bella conspicuously luminous because fictional characters in general are more luminous than real people. (Authors have perfect access to knowledge about character minds, and since the dearth of luminosity in real humans isn't known to most authors, they don't restrict the characters' access to this information much if at all.) I've resorted to some tricks, most notably the notebooks - how do people find Bella's visible luminosity?
5sketerpot12y
I wonder if real people could become more luminous by occasionally narrating their thought processes from a third-person perspective, treating themselves like characters that they're writing. If nothing else, it'll be a cute gimmick for getting someone to examine their own motivations. I'm going to try this later today, while exercising. We'll see how this wild-ass idea fares. (I will define failure as not turning up anything surprising.)
3Alicorn12y
That could be interesting. Do report back.
6sketerpot12y
I tried out my idea, and it worked. It wasn't too spectacular, but it was well worth the effort. I decided that, in order for this to be a proper test, I would look at something that I wasn't really comfortable with: my shyness and difficulty in social situations. I figure that there had to be some obvious irrationality clunking around my skull there. I started describing this guy (myself), and laying out the reasons for his social discomfort in a straightforward exposition dump. Several times, I had to pause and ask myself if the explanations actually made sense -- was this true, or an incorrect rationalization by an unreliable narrator? The process was surprisingly adversarial! I came to two surprising conclusions. First, the deeper cause of a lot of my problems is that I have difficulty quickly finding topics of common interest with most people in most situations, so conversations with strangers tend to end quickly and abruptly, which sucks. A previous thread had advice for improving this skill; I'll see if I can find it, and give it a try. Second, there's an even deeper problem that underlies my shyness: I want to not be disliked by anyone, but that's paralyzing and leads to crippling shyness. Far better to be more open with my personality, and accept that someone is probably going to be pissed off by any sufficiently cool person. I'm going to try letting my quirkiness out more, since some people seem to find it really charming, and I enjoy it. Even though this method worked, it seemed pretty much equivalent to the introspection method where you explain something to an imaginary person, while listening to yourself carefully for anything that sounds like bullshit. I think that method is easier since it doesn't require the third-person pronoun shift, which turned out to be superfluous. Really, the most important things seem to be: 1. Come up with an explanation for something, and put it into words. Explain clearly, as if your listener doesn't know wha
1WrongBot12y
I do something vaguely similar to this: a lot of my introspective thought takes the form of imagined dialogues with someone who I think would take the other side of the argument, or at the very least need convincing. For example, in a lot of my thinking about metaethics recently, (an imaginary construction of) Eliezer gets cast in the dissenting role. This seems to help me avoid arguments I can't justify, though far from perfectly. (I may have a metaethics post in the pipeline.)

Typo fixed - thanks :) (Note that I'm fixing typos on Luminosity's own website [http://luminous.elcenia.com] only, not on FF.net due to interface hate. This one was a current typo, but if you're spotting them on FF.net instead of the Luminosity site, they may already have been caught.)

This link is dead right now. (I also got emailed it by the fanfiction.net subscription thingy.) Chapter 3 typo alert: "disintersting" --> "disinteresting".

The link works for me. I'm not sure what might be wrong with it. I will fix the typo, but FF.net takes for-freaking-ever to push adjustments to content. Here [http://alicorn.elcenia.com/luminous/] are the chapters extant on my own webspace, where they should behave. (I will continue to update on FF.net too in order to attract the attention of more conventional fic readers.)

I think she comes off as in control of her life and very insightful about other people, but not particularly insightful about herself (at least in contrast to other fictional characters - your theory about why this is makes sense to me). On the other hand, her insightfulness about other people didn't seem at all forced, so her social modeling abilities seem to be working.
0katydee12y
I'm skeptical of the claim that most authors don't know that real humans are unluminous. The authors that I have met in person haven't seemed particularly luminous to me, and I see no reason that they would think that people in general would be so. I suppose that they could all model their writing on other writing instead of on the world as it exists, and thus excess luminosity in fiction could quickly propagate, but this seems somewhat implausible.
1Alicorn12y
Being unluminous is actually not useful in determining that humans are unluminous.
1katydee12y
Why would authors model fictional minds with unusual high-level skills that they do not possess and, in all likelihood, have neither heard of from other sources nor conceived independently?
6Alicorn12y
Because the lack of skill is not transparent. By way of analogy, it takes a reasonably uncommon bit of knowledge to be aware that human vision includes blind spots and to know how they work. Even though every single human has blind spots (if indeed they can see at all), and can determine the existence of these blind spots through easy tests, many authors will not think to write fictional characters with visual blind spots, because it is not obvious to people going about their ordinary lives and looking at things that they exist. The author knows what's within visual range of the character, and if the character has his or her eyes open, (s)he can see all of those things. Luminosity is rare. Knowledge that luminosity is rare is rare. Most people trust in naive introspection. They believe the first approximations that pop into their heads when they think about themselves, in the same way that they accept what their visual cortices tell them. And they know what's in the character's mind, and if the character introspects, (s)he can see all of those things.
1katydee12y
I think I might not get it. How could someone be introspective but not luminous? I haven't put any real effort into reading the luminosity sequence because it seemed so fundamentally obvious to me. It is possible that I am low-level and deceived in ways that I am totally unaware of, but it's always been easy-- trivial, even-- for me to see through my brain's "fake explanations" and understand the actual reasons behind my thoughts or traits.
2Alicorn12y
Sounds like you're an anomaly, if what you say is true. Naive introspection is generally fallible.
2katydee12y
What are the standard failure modes that you've encountered? I need to test myself more thoroughly.
3rhollerith_dot_com12y
I am going to assume provisionally that you do not mind answers from people other than Alicorn. Situations that have probably caused me to become less aware of the true reasons for my thoughts and actions: * needing to stand up for myself, i.e., to argue on my own behalf, in what a friend of mine referred to as a "pecking situation," i.e., one where ordinary people without a strong commitment to epistemic purity constantly try to one-up me and each other; * needing to sell myself, e.g., in a long series of job interviews or dates; * living for months with chronic pain; * getting older (I am 49); * being very afraid (end of list). The changes I found myself required to make to myself over the months and years to become marginally competent in the "pecking situation" almost certainly interfered with my self-awareness though I never despaired of my eventually regaining the self-awareness with enough work. Something caused me to pay much less attention to my felt sense and my moment-to-moment emotional reactions, and my having lived for years with chronic pain is one of the most likely causes.
1[anonymous]12y
There's some "obviousness" to it, yes. I think that's not necessarily a fault; it's easy to grasp the idea of luminosity, but sometimes people don't do it. Can you do it under stress? It's simple -- but not necessarily easy.
0NancyLebovitz12y
Well, there's the joke that authors understand themselves more than anyone else does-- not necessarily better, just more. I do think it's possible to be fascinated by one's own internal processes while not noticing a few hot button areas.

katydee: Warning: bombastic (but sincere) sentence ahead. [There were two paragraphs here, but Less Wrong is better without them. It is not that I concluded that on second thought, what I wrote here is wrong, but rather that if I just assert it in a shorthand way like I did, and do not provide any arguments for why I believe it to be true, well, most are going to find it ridiculous, and I do not have time to advance the arguments or even to explain with sufficient care what my assertion is. Another factor that had a slight effect on my decision is that I have not read Alicorn's luminosity sequence.]

I would wait until we have a definite sign of interest - e.g. a conversation about something in the story on an open thread that attracts a fair amount of conversation.
5rhollerith_dot_com12y
Here goes. Since I had not read any of the books or seen any of the movies, I lacked confidence that I possessed the prerequisites for reading your fanfic. It turned out that I did possess the needed prerequisites (for reading Chapter 1) but I almost concluded otherwise and almost stopped reading when I got to the first reference to Charlie because I did not know who Charlie is. But then a few sentences later it became obvious that Charlie is Bella's father, and I read to the end of the chapter. In summary, my feedback to you is that this particular reader would have benefitted from a replacing of the first occurance of "Charlie" with "My father, Charlie." I want to know what happens next :)

In medias res this one. Start it in the middle of something interesting happening.

I wanted to do that - the original book does it - but I haven't yet gotten very well acquainted with my Bella and by the time interesting things start happening, I wouldn't expect her to let me hug so close to canon. I might go back and add something like that in a few chapters.

Have you ever read any of L.E. Modesitt's fiction?
0[anonymous]13y
What about it? (I'm looking for good fantasy fiction)

I think some of Harry's annoyingness is due to the fact that he's modeled after young Eliezer. He's a mix of wish-fulfillment for young Eliezer and an opportunity for older Eliezer to criticize his younger self. This is really apparent with the chapters involving the Sorting Hat.

Culture shock can be tiresome for the people not suffering it. I've been reading blogs and forum postings by expats in South Korea lately, and that constant perpetual shock & outrage? Par for the course for some people.

A lot of kids are obnoxious and hyperactive. Shock and outrage are IC too. (Not that I think Harry is obnoxious or hyperactive or too shocked and outraged.)

For "Harry Potter and the Methods of Rationality", I'd like to make predictions that can be eventually verified publicly in time, but won't tempt the author to change things to prevent it from coming true (as is the usual way of serial writers on the Internet). I'm therefore encrypting my prediction with the md5 hash function, so that afterwards it can be verified. (One difficulty is that I have the power to edit this comment; is there a way to make it obvious if I've done so, or store it in a less editable space?) Anyway, here goes:

When the -n flag is added to the echo command (as suggested by ata) the hash matches. So, unless orthonormal has exploited a security vulnerability on the Less Wrong server, orthonormal has expended a costly number of computing cycles to defeat the purpose of the hash function, I misunderstand the cryptographic guarantees provided by the hash function, or something equally unlikely, orthonormal really did write the following back on 25 July:

If I assign p=.99 to an outcome and the outcome turns out to be false, it is a good bet that I misunderstood the question or misunderstood some proximate cause of the outcome, and in this case, the proximate cause I am most likely to misunderstand has to do with properties of hash functions.

You can have a third party create a cryptographically signed timestamp for you. For example, secure-timestamp.org [http://secure-timestamp.org] will do this. This can only be falsified by getting the timestamping server's private key or breaking its crypto algorithm. For things more important than Harry Potter predictions, you can have multiple third parties timestamp them for you, in which case falsification requires stealing all of their private keys.

MD5 is utterly utterly broken and recommended against for any purpose. Use SHA-1.

0apophenia12y
So, we're returning to the days of math challenges? (i.e. the debate over the calculus?)
0JoshuaZ12y
I think you're confusing separate issues. The idea of having contests where two mathematicians would each issue challenge problems to the other was primarily an event in the Middle Ages. This idea then continued in some forms with people like Fermat (later Middle Ages or early Renaissance depending on how you define things) who would issue challenges to others to prove what they had already proven. What Orthonormal is doing actually more closely resembles a practice from the 19th century where when multiple people were racing to solve a problem first, they'd every so often deposit a sealed envelope with some reputable independent body to verify issues of priority.
0apophenia12y
You're right, I was confused on the dates. I'm not referring to the sealed envelopes, but rather to the practice by which an alchemist/scientist/mathematician/etc would write a succinct summary of their discovery (i.e. "to transmute gold, add salt") and write the letters in alphabetical order. They'd publish this somewhere public. Then, if someone else discovered the same thing, they would say "aha, but here's my discovery" and point out how they came up with it ten years earlier by giving the "unhashed" version.
0orthonormal12y

Pastebin maybe?

Wow. I liked 28! Well, I liked all but 1 of the previous 27 too but this one was brilliant. Just the right balance of overconfident recklessness combined with not being a stubborn fool when realizing his mistake. By right balance I mean for realism given the character. Harry being such an emotionally unstable prick was a little irritating until he started showing clear signs of being aware of his emotional foibles and the rather important ability to take care of important relationships despite his weakness.

From Ch. 7:

Draco snarled. "She has some sort of perverse obsession about the Malfoys, too, and her father is politically opposed to us so he prints every word. As soon as I'm old enough to get an erection I'm going to rape that bitch."

Is this a reference to some poorly-written slash fanfic? I'm assuming Eliezer knows that boys of any age can get erections, so it must be making fun of something, but I'm missing a reference.

Similarly with:

Harry burbled on. "I'm delighted to meet you, Mr. Malfoy. Just unutterably delighted. And to be atte

5gwern13y
The newspaper headlines are, I assure you, making fun in general (at the very least).
3pozorvlak12y
Yes, I found that sentence really jarring too. Even assuming that Draco was for some reason unable to get an erection, he'd hardly admit it.
2NihilCredo12y
That sentence actually sent me on a quick Google mission to confirm that the author was a woman.
1Blueberry12y
It would have to be; a male would know that boys of any age can get an erection. Did you find the original author of that line? I couldn't find it through Google
7knb12y
It seems plausible that Malfoy wouldn't know that. Some boys never get erections before puberty. Getting erections reliably (as opposed to accidentally) before puberty might not happen either.
2ata12y
At this rate, Draco will be a master Bayesian before he figures out masturbation... (sorry, sorry)
1pozorvlak12y
Actually, that was something about the original books that really bugged me: their sexlessness. Rowling captures the frustration and rage of being an adolescent boy very well, but not the lust - and that's probably deliberate. Sue Townsend's Adrian Mole books are much better in this regard.
1Cyan12y
Wow, I haven't thought of Adrian Mole in years. I enjoyed those books when I read them -- I should read them again and see how they stand up. Thanks for the reminder.
0Blueberry12y
Source for this? I would be very surprised if this was true, except possibly in cases of extreme sexual dysfunction caused by a severe injury.
4knb12y
If you don't believe me, do a google search. Lots of people on "ask the community" websites like Yahoo answers have asked whether prepubescent boys could get erections. Some of these people are adult men. In any case, obviously Eliezer didn't know that or he probably wouldn't have included that tidbit!
-2Blueberry12y
A google search didn't turn up anything saying that some boys don't get erections before puberty. Why do you think this? Yahoo answers isn't an especially reliable source, and it looked like most of the people asking were women, but I guess it's possible that some adult men forgot what it was like to be a kid. As I said above, my theory is that Eliezer wrote that line to make fun of fanfiction.
4NancyLebovitz12y
Alternatively, male sexual development might be more varied than is commonly believed. Or the Malfoys might put a lock on their kids' early sexuality to make them easier to control. Something like that might make arranged marriages less prone to drama. I think this might actually be feasible. Malfoys are probably not likely to have intimate enough conversations with children from other families that something odd is going on, and could write off what other children imply as just big talk. Or the children could find out the truth relatively early, and buy into a family belief that this is the sensible way to do things rather than an imposition.
2NihilCredo12y
Given how much emphasis a Malfoy education places on preserving your status and appearance of power, it's fairly silly that Draco would so openly and freely reveal such an important (at least symbolically) deficiency.
0NancyLebovitz12y

1Sniffnoy12y

0pozorvlak12y
Or we've just learned something about Eliezer's sexual development that I, for one, would rather not have known.
0Blueberry12y
That is possible but it seems less likely. He's young and sex-positive, and there are other fanfiction references in the story as well, so it wouldn't be too surprising if he included another.
0[anonymous]12y
Or he was too busy to play with himself.
2WrongBot12y
Uh, that's Eliezer's, from one of the early chapters of MoR. Unless he's making a reference I didn't get?
1Blueberry12y
I assumed it was a reference to the way young kids sometimes write slash fanfic when they don't know anything about sex, and they make all kinds of mistakes. There are other fanfic references, like Harry's line to Draco, "It makes my heart swoon". I don't know if it's a reference to anything specific, but NihilCredo seemed to suggest that e found it.
5NihilCredo12y
Actually, what I meant is that I cannot possibly conceive an eleven-year-old kid openly admitting that he cannot yet have an erection - he'd rather jump into a fire. It makes me wonder what kind of kids Eliezer hung out with. In most Western societies, boys' relation with sex moves straight from "knowing nothing" to "pretending to know everything". (Wizarding Britain could be different, but there is nothing in Rowling's or Eliezer's writings to explain that.)
3NihilCredo12y
And Eliezer has just fixed the sentence (along with a few other small tweaks to Chapter 7). Glad to see improvements!
7Furcas12y
The new sentence is a bit lacking in the original's shock value. I would have left the "that bitch" part in.
6Eliezer Yudkowsky12y
I'm not sure the Draco I've been writing for the last few chapters would use the term "bitch" in front of Harry Potter, it doesn't sound dignified enough for the heir of Malfoy. (But yes I did explicitly consider that alternative. If I get enough votes for keeping the shock value I'll put it back in, or figure out something, I guess.)

the shock value

Rape isn't nearly shocking enough. We need naughty words.

5WrongBot12y
This, unfortunately, is precisely how most people's minds work.
5Eliezer Yudkowsky12y
Correct. Do I need to point out again that no one even noticed the thing with the monastery?

It is expected that villains, even in the canon of children's books, will kill and maybe occasionally torture victims in order to establish that they are bad. It is not expected that villains, especially in the canon of children's books, will permit/condone/commit rape. Additionally, the sorts of emotions that are commonly supposed to precede murder and torture are more familiar than the sorts of emotions that are commonly supposed to precede rape, and so someone unfamiliar with the actual etiology of any of those crimes finds rape less relatable and more shocking.

5ata12y
Agreed. I also think the original "Which of these characters has crossed the moral event horizon?" question (in one of the Author's Notes) was a little bit misguided because, as far as most HP readers are concerned, Voldemort is already considered to have passed the moral event horizon from the outset. There's little he could do that would make us think "Wow, I didn't know Voldemort was that evil". And 11-year-old Draco, being the son of a Death Eater, might be expected to hold certain evils as justifiable or compulsory — we expect that he's been conditioned to find it acceptable to kill, torture, and exploit non-purebloods, and generally to manipulate people for his own ends. And as long as he's still young, we're inclined to be relatively lenient in judging him for those attitudes, considering he has never learned anything else, nor been allowed (or allowed himself) to reconsider it. What we don't expect is for him to talk casually about committing rape, considering that nobody in the series does, even the darkest of the canon dark wizards; it makes it seem like it's an idea he came up with on his own, like he just heard a definition of rape and thought to himself "Hey, that sounds like a fun thing to do to young female political enemies, and I bet I could get away with it, too". So I bet most of the objections were based not on thinking "that's more evil than Voldemort", but "that's way more evil than Draco is supposed to be right now".
9Eliezer Yudkowsky12y
Those are the children's books version, and MoR is not a children's book, nor is most fanfiction. If you'll pardon the size of the hypothetical: If the Death Eaters actually existed, no way in hell are the males not committing rape.
4Alicorn12y
This is true. But even among works of fanfiction, the ones that point this out tend to also be the ones that are full of sex acts in general, which MoR is not.
9Eliezer Yudkowsky12y
MoR points things out for the sake of pointing them out, by way of trying to teach the art of the awakened mind. Actually I'm not clear on what if anything we're arguing about at this point.
3katydee12y
I see no need to limit that claim to the males.
-5b1shop12y
0ata12y
I agree. My point was only that, in the context of the canon, having an 11-year-old boy talk about committing rape seems more jarringly unexpected — narratively, not inferentially — than having him talk about committing torture and murder (or having an adult Death Eater commit or talk about committing rape), relating to my point that the "Which of these characters has crossed the moral event horizon?" question was probably not relevant to people's actual objections. (For the record, I'm not arguing the line shouldn't be there, and I don't disagree at all with your rationale for including it. I'm just trying to imagine the thinking of people who did react negatively to it.)
3NancyLebovitz12y
Would people be shocked if they found out that Voldemort didn't believe in Pure Bloodism and/or didn't care whether it was true-- he was just using it as a means of getting power and an excuse to kill people?
4wedrifid12y
Huh? That was what I assumed when reading the books. I recall some 'blood purism' claims but thought they were just cheers. The sort of thing that only the low-to-mid level death eaters actually believe, before they evolve enough to actually 'get it'. I suppose on reflection that in a fantasy story I should expect the 'evil' to be blamed on something politically incorrect rather than on universals of human nature.
1NancyLebovitz12y
I'm reading this [http://www.redhen-publications.com/PostMortem.html], which goes into some detail about how carelessly built the Harry Potter universe is. Still, while blood purism is an obviously easy win for the author, it strikes me as pretty well built into human nature to have a destructive political movement based on amping up prejudice. What would you consider to be a more universal basis for evil?
8gwern12y
I have to say, for a blog (?) focused on good writing and story structure, that's a really terrible essay/brain-dump - highly repetitive, problems mostly alluded to rather than described, fact & citation-free, and very very ranty. (I suspect I'd also find a number of self-contradictions if I cared to re-read.) If it didn't have the occasional good insight, I'd never have finished reading it. I did, but I still hate essays which are intermittent reinforcement schedules. But here's one good point. By the end, the real sin of Voldemort is not being evil, but in seeking to avoid death. Rowling implicitly seems to be saying: 1) you can't live forever 2) you shouldn't avoid death 3) death is good. LWers may grudgingly accept #1 ('fine, I can't live for ∞ but can't I live for a few thousand years at least?'), but I think we all pretty much vociferously disagree with #2 & 3. And if we were put into the Potterverse, I think we would pretty quickly all go over to the Dark side. And that observation suddenly changes my interest in MoR from 'what is Quirrelmort's grand plan?' to 'how does Harry rewrite Good & Evil and fix that sordid little world?'
8JoshuaZ12y
Would we go the Dark Side? I'm not sure. I think most people here would not murder someone to get the chance at a few extra centuries of life. And it seems that making a Philosopher's Stone is not a Dark Side event, although why no one other than Nicholas Flamel makes one is never made clear. Mass produce Philosopher's Stones maybe?
0gwern12y
I'm afraid that still puts us on the Dark Side; even wise and great Dumbledore and Nicolas Flamel weren't allowed to use a single PS for, at max, more than 4 centuries. Indefinite use by any joe schmoe...
4NancyLebovitz12y
Thanks. I'd been wondering why I was having trouble focusing on the essay, and thinking the problem might be me. I kept reading it because I thought a lot of the zip in the series faded out in the later books, I hated the epilogue with a passion, and was hoping that I'd get some explanations for why. I think I got some partial explanations, though I got tired of the theories about what Rowling must have been thinking. Also, at the point when I'd mentioned the essay, I hadn't gotten to the material about accepting death nor the revolting chunk of resentment about how Rowling cheated to make her books popular by not concealing that she's pretty. "Accept death" is a cheap and easy way to add profundity to fantasy and science fiction. I think the anti-immortality stories are pretty much sour grapes, and there are a lot of those stories. Peter Beagle's built a big chunk of his career on them. Rebecca Ore's Centuries Ago and Very Fast [http://www.amazon.com/Centuries-Ago-Very-Fast-Rebecca/dp/1933500255/ref=sr_1_1?ie=UTF8&s=books&qid=1280583490&sr=8-1] is an exception-- the main character is non-aging and a time traveler, he likes his life, and he has a pragmatic ability to enjoy it.
5gwern12y
I too was tired - of his incompetence. There is a lot of value to critically sifting authorial statements over decades about multi-installment works. But his sucked. If you want to see it done right, in a way that completely revolutionizes your interpretation of the source material and gives you genuine insight, resolving all sorts of continuity issues, plot holes and whatnot, proving its case with citations and points beyond a reasonable doubt, the beau ideal would have to be The Secret History of Star Wars [http://starwars.wikia.com/wiki/The_Secret_History_of_Star_Wars]. I doubt you've read it, but take this old SW fan's word for it, it was a masterpiece that that essay comes nowhere near.

I was more interested in what he had to say about the books themselves rather than his guesses about what Rowling was thinking. I'm not likely to get around to The Secret History of Star Wars, but if there's a short answer, what happened to Lucas between the end of the first trilogy and the beginning of the second? He seemed to have forgotten most of what he knew about telling stories. "A long time ago in a galaxy far, far away" is brilliant. Starting a movie with a scrolling description of the tax(?) situation isn't.
4gwern12y
The short answer is that A New Hope had nothing whatsoever to do with any grand story about Darth Vader, who was merely a mid-level flunky of the Empire. Empire Strikes Back and Return of the Jedi frantically retcon this, but Lucas simply didn't have a decent backstory centered around Darth Vader and couldn't come up with one. The longer answer goes into the above, and also points out that Lucas's support network (of beta readers, if you will) which edited and improved his trilogy had largely fragmented or vanished by this point. For example, his wife, a very skilled film editor, had divorced him by the time of the prequels.

Me too. I stopped reading the essay because of this.

J. K. Rowling once said that Harry Potter was a story about death.
1JoshuaZ12y
Citation? I think I've read a fair number of JKR interviews and I don't remember her saying this. A quick Google search doesn't turn anything up but my Google-fu may be weak.

Your Google-fu is weak; a search like http://www.google.com/search?num=100&q=%22J.K.%20Rowling%22%20%22Harry%20Potter%22%20death%20interview [http://www.google.com/search?num=100&q=%22J.K.%20Rowling%22%20%22Harry%20Potter%22%20death%20interview] turns up Wikipedia linking to several interviews, and then some quick C-fs turn up: http://www.accio-quote.org/articles/2001/1201-bbc-hpandme.htm [http://www.accio-quote.org/articles/2001/1201-bbc-hpandme.htm]

No, because the books heavily imply that Voldemort didn't believe. He was not pure-blood himself (Adolf Hitler, incidentally, was a very bad example of the Aryan ideal). And, I think that the discussions of how Voldemort chose to interpret the prophecy as referring not to Neville (as pureblood as they come) but to Harry (who, through his mudblood mother, is impure) specifically take this tack.
5Leonhart12y
Interesting. My recollection was that as the books progressed, the plausibility of LV not caring about pure-bloodedness grew larger, but he himself didn't admit to any such thing onscreen. Then in Deathly Hallows he suddenly did care about it again, because Rowling suddenly realised that he didn't actually have a motive at all. So any old ill-fitting one would have to do, as part of the overall trainwreck. Then again, my perspective on HP has been thoroughly polluted by the brilliant essays over at http://www.redhen-publications.com/ [http://www.redhen-publications.com/].
5gwern12y
Voldemort says so little on-screen that I don't really get much out of him. His minions certainly do get more pure blood-centric as time goes on - look at Dolores Umbridge even before Deathly Hallows.
4NancyLebovitz12y
Thanks. I really should give up on having opinions about most details in the books-- I've read them at most three times (once for the last two) and have forgotten a lot of detail. Do you think the Death Eaters really care about Pure Bloodism? Is MOR's Draco being shocked to find out that Pure Bloodism isn't true just a sign that he's young and naive?
9gwern12y
Only twice here, but I have a good memory for written material, and the ideology, physics, and philosophy of Harry Potter interested me long before MoR - so this is just an old topic for me. Some do. The Blacks and Malfoys, probably. Others are in it to 'back the strong horse', and others are in it because it gives scope to their sadism. Yes. Eliezer has written about 'nonoverlapping magisteria' before: they are transparent efforts to shrink religion to something which can't be falsified, an effort at special pleading. Even though religion (especially Western ones) have made many empirically falsifiable claims - which largely have been falsified. A very young person might take those claims seriously and be shocked that they are falsified. To not know theological explanations of the theodicy (a topic recently relevant because I finally got around to reading Eliezer's Haruhi [http://www.fanfiction.net/s/5588986/1/Trust_in_God_or_The_Riddle_of_Kyon] story (which was very good)), to not 'believe in belief', to not dismiss empiricism, to lack all those sophisticated dodges and excuses that intelligent adult theists use to remain theist - this we call 'young and naive'.
1NancyLebovitz12y
Is it plausible that Lucius would allow Draco to be that much of an idealist?
8gwern12y
Sure. What would Lucius worry about disillusioning Draco? The anti-pure blood wizards don't have a leg to stand on, unlike theists and atheists. (Think back - do you recall any good arguments made against pure blood, the theory as opposed to the believers? Rowling assumes we'll instantly identify pure bloodism == racism, and that's that. If they think any harder, most people will fall into the usual trap of thinking that exceptions/brilliant-mudbloods like Hermione Granger disprove pure bloodism, which of course they don't. The history of the Wizarding world is even more consistent with pure bloodism than not!)
2NancyLebovitz12y
It wouldn't just be about Pure Blood. It would be about not having any abstract loyalties of any sort-- Malfoys want to be in charge because it's more comfortable at the top.
7MBlume12y
Were Robin here, I suspect he would point out that allowing your children to remain innocent and naive is a sign of luxury, and a signal of high status. Lucius would be embarrassed not to have his 11-year-old son appear innocent and naive. ETA: Childhood innocence is conspicuous consumption!
1NancyLebovitz12y
Yes, and note that Draco expects to spend his life catering to idiots. Harry's upbringing is clearly higher status.
4wedrifid12y
That sounds exactly right to me.
2ata12y
I'd be somewhat but not entirely surprised if I learned that about canon Voldemort. I'd be pretty surprised if Smart Science-Aware HPMoR Voldemort hasn't figured it out (not sure how likely it is that he knew all along).
2NancyLebovitz12y
My deduction was that the Malfoy family culture included rape for spite, not that it was something Draco came up with.
2ata12y
The new wording — "As soon as I'm old enough I'm going to rape her" — makes it sound, in the absence of any alleged biological limitations now, like it's some sort of traditional rite of passage in the Malfoy family. (Or at least that's what it made me think of. Probably not the intended meaning.)
0Blueberry12y
I wouldn't be surprised if it were one.

9ata12y
Was there supposed to be something after that quote, or did you cast a non-verbal Protego and deflect one of my points back at my own argument? (If that's the case, I don't quite see the significance of that line. Is it that we're supposed to have the same attitude toward Draco?)
5WrongBot12y
I suspect that Eliezer may be taking that statement as a challenge.
0wedrifid12y
I certainly hope so.
3NancyLebovitz12y
Also, murder can be presented in fiction with enough distance to be fun, but this isn't true of rape. Note that there are mystery weekends for solving murders, but not for solving rapes.
0Blueberry12y
Aren't the sorts of emotions that are commonly supposed to precede rape just extreme sexual arousal, frustration, and anger? Is that what you mean? I'm not sure how accurate that is in real life but that doesn't seem too unrelatable.
5Alicorn12y
It seems to me that people think rape is preceded by sickness, as in "he must be a real sick bastard". That's in large part because the common picture of rape is someone leaping out of the bushes at a random stranger, when a lot of rape is actually between acquaintances who know each other, and like or at least voluntarily spend time around each other.
0Furcas12y
There are few people above the age of 10 who find the word 'bitch' shocking nowadays. What was shocking about it isn't its 'naughtiness' (??), it's what it revealed about Draco's mentality, namely that it's polluted by a good amount of medieval misogyny.
2Blueberry12y
I vote for putting the shock value in. I'd also change it to "When I'm old enough, I'm gonna rape that bitch and knock her up" or "When I get a chance, I'm gonna rape that bitch." As well as being old enough to get an erection, 11-year-olds are old [http://www3.interscience.wiley.com/journal/119171327/abstract?CRETRY=1&SRETRY=0] enough [http://www.timesonline.co.uk/tol/news/uk/crime/article3285383.ece] to rape [http://www.breitbart.com/article.php?id=D8T0PI481&show_article=1], though of course this could just be Draco's bravado.
3NancyLebovitz12y
I have a notion that this bit (especially the earlier version where Draco admits to not having erections yet) was the result of story constraints. After somewhat about the Malfoys being pretty cool in ways which are important from the point of view of the story, it was necessary to shockingly remind the reader that they're also morally deficient and seriously bad news. At the same time, it was also a good idea to make this a hypothetical threat-- the story line isn't now (and perhaps not ever) about Hermione being in danger.
2Eliezer Yudkowsky12y
Read chapter 22 and 23, then look at what you just wrote. Are you sure that's the same Draco? If the passage actually does need more shock value (and I'm not quite sure that it does, especially given the wide variance in reader taste and the number who enjoyed the rest of the fic but thought that one part was too shocking) then it has to be more in-character for the later-revealed Draco. There's a simple way to increase the shock without adding vulgarities that polite young Death Eaters don't use - namely, substitute "torture and rape" for "rape" - but I already think this whole conversation is getting a bit off-topic for LW.
1gwern12y
It didn't bother me. If Malfoy was thinking about self-control and wasn't really bothered, he wouldn't be using a curse at all; once your self-control is lost, it doesn't matter whether you use 'bitch' or some amusing Elizabethanism like 'trull' or 'maculate hobbyhorse'.
6Sniffnoy12y
Can we maybe get a list of these changes somewhere?
0NihilCredo12y
Don't think so, sorry (unless archive.org or similar sites are especially zealous with ff.net). But you can do what I did and add the various chapters to the Update Scanner extension for Firefox, which will do the job for you.

Oh, I was more of hoping we could prod Eliezer into supplying us with a list of such. :)
0Eliezer Yudkowsky12y
Well, for one thing, sometimes Orwellian Retcons are there for important future reasons. It's one thing if someone reads Chapter 7 well enough, before and after, to spot the other change I made to Draco; but having a little automatic computer notifier makes my life more nervous. Also, what kind of load does Update Scanner put on FFN's servers?
5Sniffnoy12y
I was thinking more for the benefit of those of us who only saw the older versions rather than for those of us who only saw the newer versions...

Yes, a diff would be great, so we don't need to read the whole thing to get the Orwellian Retcon.
2JoshuaZ12y
Well then, please keep notes on the different versions so that future historians can look at the versions. I estimate a small chance that historians will be interested in this work (< 5%), but if one puts a high probability of a Singularity then the probability goes up a lot. So you would presumably think that it is worthwhile to keep them.

Unfortunately, which category you belong to won't be apparent from a random post, unless you happen to drop some illuminating clue (say, a screenshot of your porn folder).
9Blueberry12y
Do Singularitarians like a different type of porn than non-Singularitarians? I guess transhumanists might be more likely to like animated or photomodified porn... I'd love to see some Singularity porn. The Prime [http://www.kuro5hin.org/prime-intellect/mopi1.html] Intellect [http://www.kuro5hin.org/story/2003/5/17/212828/593] stories might be included in this genre, thought they're a lot more than just erotica.
5PeerInfinity12y
ok, I just have to reply to this comment... I am a Singularitarian, and yes, I think I do like different porn than non-Singularitarians. Porn of stuff that won't be possible until after the Singularity. Porn of nonhuman beings: furries, aliens, fantasy creatures, robots... and beings of nonstandard gender. Not just remixes of the standard male and female genders, but entirely new genders too. And yes, I also like tentacle monsters :) And that's just the sorts of images I like. There's also the role playing I do in Second Life. I do stuff that's only possible in a virtual reality. Morphing my body into whatever form I happen to find convenient, creating and manipulating virtual objects in ways I find useful, and of course defying the conventions of our universe's physics. And sometimes even directly manipulating my mental state, or doing stuff like telepathically sending out waves of pleasure and happiness. And then there's books... My favourite transhuman sex scenes are from Greg Egan's novels. He did a good job of thinking of some genuinely original ways for transhumans to have sex. Most notably in Shild's Ladder, with the aliens whose genitals form new and interesting shapes by exchanging pheremones with their partner. And also Oceanic, which featured the "bridge", which allowed the inhabitants of the planet to swap genders with their partner after they have sex. And then there's the 7-gendered society in the novel Distress. And one brief scene of virtual reality sex in Permutation City, and also a couple of his other short stories... hehe, sex positions that are only possible in 4 spatial dimensions :) I didn't like Prime Intellect though, it involved way too much pain. Actually, when I read those scenes, I imagined what they would be like if the people modified their minds to experience pain as a new form of pleasure. That... was interesting :) Sorry if this is totally off-topic for LW, I just couldn't resist replying to that comment :)

You mean the removal of "there's plenty of girls out there who deserve it", or some other change you made in the past? And why is the auto-scanner anything but good for anyone?

0Eliezer Yudkowsky12y
Oh, some other change I made in the past.

Speaking as someone who everyone rightfully believes about everything, MoR is awesome (at least up to chapter 21) and everyone should read it. It also might serve as the best introduction to the power of rationality, but we've yet to see that it really makes awesomeness happen in the real world, rather than just for those of us who are cheering on Harry's thoughts.

Hm, inconsistency: I just noticed that Quirrell says in chapter 16 that Quirrell points will determine generalship of armies. That seems to have been abandoned at some point?

Up to chapter 31 now. I don't understand how Eliezer is going to paint the central conflict. Granted, Quirrell is awesome and has had several successes already. But the main motivation of the Death Eaters is blood purism (as in canon), and Harry has already proved it to be false, and our Quirrell is rational enough to agree with the proof if he hears it. So to make the central conflict happen Eliezer has to invent something else, something secret, that makes Quirrell tick.

3NaN12y
It appears that a very large number of wizards are blood purists; Quirrel might just want power, and think that the best way to achieve that is by stirring up hatred for mudbloods.
3Baughn12y
I think he may have already done so, by way of Quirrelmort's reaction to Harry's statement that he wanted to use science. Voldemort is scared of muggles. Quite reasonably so; despite Harry, there are enough of them that they'd very likely overtake the magic-users in a matter of decades on all useful fronts, and even now a conflict between muggles could squash the wizards like a bug. Basically, I think he wants to (a) Strengthen magical society to the point where they can stand up to the muggles. Harry might be helpful here, but there's a good chance their plans would conflict. Failing that.. (b) Get the hell off this rock.

I previously criticized Eliezer's 'Ultimate Mega Crossover' fic on basically the grounds that it makes him/SIAI look bad, and didn't help out the cause much.

Reading through MoR, I made a point of reading the reviews and seeing what non-LW people were saying. I'm pleased that aside from AngryParsley's site stats, many of the reviews expressed interest in LW writings and Eliezer's ideas, and very few any disgust or general opinions of low status. Good job, Eliezer!

3NancyLebovitz13y
Have you updated any of your underlying premises? I suggest that for a lot of the people you want to attract at this stage, consuming a lot of sf is proof of normalcy. As for fanfic, I suspect that the type of fanfic matters a lot-- if it had been slash of comparable quality to the existing work, there would have been a substantial yuck factor to surmount as well as people who were enthusiastic. I don't know what the result of HPMOR is going to be if SIAI ever wants to get bank loans-- there are a lot of steep weirdness hills to climb at that point.
1gwern13y
I don't especially think I have; suggestions welcome.
3NancyLebovitz13y
I had one in my comment-- that respectability varies more between mainstream culture and the people who are likely to read HPMOR than you realized.
5gwern13y
Harry Potter fanfiction and its readers is way closer to mainstream culture than the sort of people who could read that crossover fic; keep in mind, Harry Potter fanfiction novels have been published as have entire books just predicting what would happen in book 7 or comprising dictionaries of Harry Potter-ania (you may remember the lawsuit over the latter).

It's really good. I'm on chapter 8, and so far it reads like a picaresque. I never thought anyone would turn Harry Potter into such a badass.

One more thought, this time money related stuff:

On the one hand, the magical and muggle economies are sufficiently separated that Gringots seems to not even notice the possibility of arbitrage...

But on the other hand, we're told that anyone who transfigures stuff to look like money, even muggle currency, is legally at war with the goblins. If the goblins are tracking muggle money enough to at least notice this sort of thing and care about it, that seems at odds with them being sufficiently ignorant of the muggle economy to not notice the arbitrage possibilities.

9Baughn13y
You shouldn't neglect the possibility that it's a law written because it seemed like a good idea, without any real way of enforcing it in general. There are certainly plenty of those around.
4Psy-Kosh13y
Professor McGonagall more or less explicitly said though that they have ways of finding out, that this matter isn't an abstract law but is very very enforced.
6Baughn13y
Yes, but wouldn't it be reasonable to think they only have ways of finding out when presented with the money in question?
8JoshuaZ13y
The goblins may only use that to check for Muggle currency that wizards try to turn in to the goblins. They may also have methods that just track objects transfigured to look like Muggle money. If goblins have similar cognitive flaws as humans, then they might be able to keep track of the economy for this one very specific purpose and not even realize that arbitrage was really a useful practice.
0Psy-Kosh13y
That seems plausible.
6CronoDAS13y
There might also be some laws restricting trade between the wizarding economy and the Muggle economy. In other words, if you take a bunch of Galleons and try to sell them to Muggles, you'll probably end up arrested or something. Part of the whole "Muggles can't be allowed to know about wizards, unless they're close relatives of wizards" thing.
4Cyan13y
You could avoid selling Galleons per se by melting them into bullion first. Maybe Galleons are unmeltable? Or the gold turns into leaves and gorse blossoms when handled extensively by Muggles? It seems like with magic at one's disposal one doesn't have to rely on mere law to prevent wizard/Muggle arbitrage.
7gwern13y
No, that wouldn't work. In MoR, the routineness of coining Sickles implies that it's routine to coin ordinary gold into Galleons; if the coinage were irreversible, then you would see Gresham's law [http://en.wikipedia.org/wiki/Gresham%27s_law] start to operate. Ordinary gold would be more valuable then an equivalent weight of Galleons because you could at any time turn the gold into Galleons but with ordinary gold you have all the other decorative and magical uses of gold available. As Galleons are created and not destroyed, ever more inflation of Galleons and deflation of gold would happen. (Have you ever bought funny money, like the Mickey Mouse money at Disney World? The Galleons would be like the Mickey Mouse money, and gold like regular dollars. Except worse.)
3Cyan13y
I am edified and grateful for it.
8gwern13y
(Magical) code is law [https://secure.wikimedia.org/wikipedia/en/wiki/Code_and_Other_Laws_of_Cyberspace] , but the laws of economics are more akin to laws of logic than legal laws - try to bend them, and you'll either accomplish nothing or it'll bite you somehow. You need subtler tactics than just unmeltable coins or disappearing specie.
2Psy-Kosh13y
Hrm... that's a possibility. Though when Harry asked Griphook, I think it was, about interaction between the two economies, he didn't say "no, that's illegal", but simply no. That's not proof, but I'd have thought it would come up if that was the issue. But other than that, maybe you're right.

Chapter 21

Draco's choice of subject. Expected, but unfortunate. It would be fun to know the physics of the magical universe. The biology is not completely exempt from the physics, of course. Also, there can be many fun incidents introduced when they are trying to sample people. Imagine trying to get a skin sample from albus dumbledore, the most powerful wizard around or trying to figure out why Aberforth wasn't that great.

The Dark Mark - They would have thought about it. My guess is the dark mark came around only after a certain power threshold was already... (read more)

What? Doesn't that flatly contradict what some character in Goblet of Fire said once?
5CronoDAS13y
Well, yes, death is irreversible in the HP universe, but there's definitely an afterlife of some kind or another.
7Eliezer Yudkowsky13y
What evidence exists for an afterlife in the HP universe? I haven't actually read the novels beyond 1-3, just fanfiction, and movies 4-6. EDIT: Since people have asked why: I read books 1-3 while I was still living in Chicago, and the whole family read them together. Then I moved out in 2000, and didn't get around to trying to read book 4 until it was time to write the fic... and found that I couldn't seem to read it. Maybe it was a change in the literary quality (I've heard others say that) or it was the fact that I'd already watched the movie and that got rid of the plot tension. Or (my personal suspicion) the fact that I'd read a lot of fanfiction aimed at a more grownup audience meant that the children's-book version of the Potterverse just didn't feel right to me any more. I feel guilty about not reading the later books, obviously, but my brain doesn't want to do it and one of the major points of this whole endeavor is that it's fun, not something I have to make myself do. So I've been getting along on movies 4-6, other fanfiction, and above all the Harry Potter Wikia. Mentioning this because TV Tropes is now giving me a "Did Not Do The Research" trope, which is supposed to be for people who didn't care enough to find out something they could've gotten in 10 minutes, and that stings a bit. I tried, I really did, and now I read the Wikia and try my best to get things right, but I'm just not enjoying the original Potter novels. Not every children's book, even ones that have taught millions of children to enjoy reading, ends up being enjoyable to every adult. "Harry Potter and the Methods of Rationality" is in the Potterverse because I was attracted to the universe of Harry Potter fanfiction.
7Kaj_Sotala13y
Curious - how come you haven't read the remaining books?
6ShardPhoenix13y
You're doing a good job of fanfic for someone who hasn't even read all the books! I'd recommend reading book 7 though just so you know what's up. edit: you obviously have some idea of what happens in book 7 from whatever other fanfics/spoilers, but still, it's another thing to read the original source.
6JoshuaZ13y
In the last book one of the Deathly Hallows is used to communicate with the dead. You should read 7 (among other things it helps one appreciate how utterly incoherent JK Rowling's notions of morality and heroism are).
3Blueberry13y
Can you please elaborate on this? Do you know the interpretation where Harry dies in the duel and everything after that is in his head as he's dying?
5JoshuaZ13y
I'm aware that people have tried to interpret it that way. I'm also very sure that that's not at all what Rowling intended. It simply doesn't fit with her general approach in the books. The heroism objection is that there's such a large deal made about Harry's willingness to sacrifice himself. But he's just found out that there's a happy afterlife where he'll get to be with his parents and everyone else who died in the books. Given that, the sacrifice is much less impressive.
4Blueberry13y
It's been a while since I've read the books, so forgive me if I'm missing something. But I thought Harry wasn't sure if there was an afterlife. He even expresses doubt whether the "afterlife" conversation is something he's just imagining in his head. Also, I think that argument proves too much: it would apply to every soldier, terrorist, freedom fighter, activist, and martyr who believes in an afterlife. Even if you intellectually believe there's an afterlife (or even if you intellectually believe your sacrifice is right) it's still difficult to overcome the instinct to stay alive.
3JoshuaZ13y
I'm rereading that section now. ROT13ed: Uneel guvaxf gung gur nsgreyvsr pbairefngvba jvgu Qhzoyrqber zvtug or va uvf urnq. Ohg ur qbrfa'g guvax gung gur pbairefngvba cevbe gb gung jvgu gur Erfheerpgvba Fgbar jurer ur gnyxf gb Wnzrf, Yvyl, Fvevhf, Yhcva vf va uvf urnq. Vg frrzf gb or gnxra sbe tenagrq nf erny. Gura, Uneel znxrf uvf fnpevsvpr naq gura orpnhfr bs gung fnpevsvpr vf noyr gb pbzr onpx. True, but Harry's certainty in an afterlife is much higher than that of any of those people, and his certainty about the nature of the afterlife is also much higher. Moreover, he's been specifically told that death isn't a big deal. Fvevhf says that it is a smooth transition. If someone is that certain about the afterlife and the nature of the afterlife, then it does substantially reduce the heroism of such sacrifices.
0NihilCredo12y
Heck, even if you were absolutely completely certain that a decent afterlife awaits you, martyrdom still mean getting the shaft. The afterlife and whatever it may offer will be waiting for you indefinitely and will presumably last a long, long time, whereas once you give up on your earthly life's experiences there's no getting them back.
0rwallace13y
"Found out that there's a happy afterlife"? You're reading a lot more into that scene than I did. My interpretation of it was that he had a near death experience, and like lots of other people having such experiences, he hallucinated something about an afterlife, with no reason to believe it was anything more than a hallucination; fortunately he was sane enough not to take it too seriously. He certainly did not subsequently behave like he had suddenly started placing much less value on life.
2JoshuaZ13y
Are we talking about the same scenes? Harry gets a hold of the Resurrection Stone and talks to his dead friends and relatives before the encounter with Volemort where he lets Voldemort kill him. That's not a near death experience, that's Harry walking along and talking to their forms. Then he has his confrontation with Voldemort. The only near death experience is after that, where Harry has his conversation with Dumbledore.

Oops! indeed we weren't talking about the same scenes, I thought you were talking about the conversation with Dumbledore. My memory of the resurrection stone scene is fuzzier, I thought it was understood to be just an illusion, but now I can't be certain whether Harry thought of it that way, or just me.
5JoshuaZ13y
Another reason to read the other books, you are occasionally making minor contradictions with her magic system that wouldn't occur if you read the other books. In particular, in the latest chapter where Hermione and Harry experiment together "If you didn't tell her at all what the spell was supposed to do, it would stop working" is contradicted by canon in Half-Blood Prince.

You shouldn't have said that! Now Eliezer will start reading all the books instead of updating his story!

It wasn't clear from the text whether that particular conversation actually occurred, or was just in Harry's head.

4 was the best book. You're missing out.
0RomanDavis13y
Five was the best book. It just makes the most sense to me, as an ending and as a story. Harry Potter becomes a teacher and freedom fighter. It is no longer the story of a boy, but of a man. The end. Everything afterward was just a bad dream.
1NihilCredo12y
Umbridge ruined that one for me. When you design a character by just stringing together hate-triggers without a single instant of sympathy (which even Voldemort has!), the result is worse than bad writing - it'll break my suspension of disbelief and make me start flipping pages. Something as simple as a pet would have made her fly under the "WARNING: YOU'RE READING A KIDS BOOK" radar.
4Alicorn12y
She has a lot of kitten paraphernalia. I wouldn't be at all surprised if she kept an actual cat that simply never made it into a scene of the book.
1NihilCredo12y
It's not the cat itself that I feel is needed; it's a quick scene of her petting a cat [http://tvtropes.org/pmwiki/pmwiki.php/Main/PetTheDog] (warning: TVtropes). (And it ought to not be an evil Persian, obviously).
1blogospheroid13y
You said it correctly here, CronoDAS. That is the exact meaning I wanted to convey - the transition is irreversible, but there is some sort of existence. Though according to the story of the second brother in deathly hallows, it does seem to be some kind of a diminished existence, unlike in Star Wars where Obi Wan states, "more powerful than you could possibly imagine."
1gwern13y
To be fair, in SW, the Force ghosts never do anything particularly powerful. (Even in the EU, the most powerful Force ghosts, like Exar Kun, usually must act through agents.) If Obi-Wan's statement is anything more than rhetoric (and it's never safe to just rule out 'it's rhetorical/symbolic'), it's a reference to Luke, who at least in the EU is basically the most powerful Force-user ever.

Chapter 34:

I totally think the "completely wrong ship" alluded to in the author's notes is Hermione/Griphook. It makes sense!

Chapter 33:

I'd come up, before, with the hypothesis that HPMoR Voldemort was actually Necessarily Evil after the fashion of Eliezer's proposed supervillain gambit, but I dismissed it by assuming that Voldemort had crossed the Moral Event Horizon already. This chapter, though, makes it very plausible again via an explicit motivation (and a Shout Out to Foundation, as well). On the other hand, Quirrell could just be playing one level above that explanation.

One thing, though: is it public knowledge that Lucius Malfoy had been a Death Eater? Because it seemed... (read more)

2gwern12y
I believe canon states that Lucius was tried in the post-Voldemort purges & Lucius's defense was that he had been under the Imperius curse. EDIT: The Harry Potter wikia, which ought to know, seems to agree: http://harrypotter.wikia.com/wiki/Lucius_Malfoy#First_Wizarding_War [http://harrypotter.wikia.com/wiki/Lucius_Malfoy#First_Wizarding_War]

Is there an annotated version of this anywhere? I know that the sequences cover most/all the stuff and am reading and have read a lot of the sequences but it seems like it might be fun to read this with descriptions of the maths/science/concepts alongside it as well as all the literary allusion noted.

You know, as I was reading chapter 32, I started thinking about how the three generals had their various weaknesses. Draco is savvy but weak against complexity, Hermione is bright but not exactly street smart, and Harry is clearly brilliant yet arrogant. It was only after I'd read it all that I realised each had fallen prey to their own specific weakness. Hermione was surprised by the combined 'For Sunshine!' Gambit against her, Draco didn't realise he was with the wrong Patil, and Harry encouraged earlier betrayal amongst his crew in order to protect him in the final battle, only to be surprised at the end. I figure this was probably a deliberate bit of writing on Eliezer's account, in which case I just want to say-Good job!

3NihilCredo12y
Draco -> Terran Hermione -> Zerg Harry -> Protoss ?
4gwern12y
Are you mad? You are assigning the happiness & sunshine army general to the Zerg, and the general of chaos to the Protoss? I'm starting to think you aren't actually a Starcraft player.
3NihilCredo12y
I went by frozenchicken's words rather than by my (single-player and replay-watching only) knowledge of Starcraft. "Clearly brilliant yet arrogant" is a lock for Protoss, and "bright but not exactly street smart" cannot be Terran. Now, chaotic fighting indeed doesn't fit with the Protoss at all. But Hermione's strategy is by far the one that most parallels a hive-mind, and for all we know the semi-sentient Zerg really are all happy-go-lucky on the inside.
0cousin_it12y
Not sure about the match, but this is definitely something for Eliezer to think about!

Ch. 32. I don't know what Eliezer will have Blaise do, but if I were in that position I'd flip a coin between Harry and Draco, get rewarded by the winner and counterfactually mug the loser. (Hoping, of course, that that Draco wins, since Harry is clearly more likely to pay off a counterfactual mugger.)

ETA: That is, of course, assuming that Blaise isn't working for Dumbledore (which his chapter-ending line would seem to point to).

Assume that Draco and Harry both value victory at $1000. Now if you demand $800 from the winner, the loser "would have" gained only $200 in the counterfactual case, so he will pay you $200 at most. So you could have just demanded $1000 minus epsilon from the winner. We could probably prove a theorem that says counterfactual mugging can't help you extract more of the surplus economic value that you create.

1dclayh12y
Excellent point! This is what I get for posting in haste. ETA: However you can extract more than $1000 if you assume that at least one of Harry and Draco would rather the other of them win than Hermione. No counterfactuals needed.
5Strange712y
Judging by the Author's Notes, my guess is that the final result is a three-way tie caused by Blaise self-terminating in the name of Sunshine.
-1Larks12y
You don't even need to flip the coin; just tell Harry you did. As Harry isn't actually Omega, this will work just as well (assuming you don't act differently)
0Larks12y
Request reason for downvote; Off-topic? Incorrect (e.g. not utility maximising)? Unclear? Sorry for whatever it was.
2Vladimir_Nesov12y
That you "don't act differently" doesn't protect you from an inference from your motive.
0Larks12y
But Harry's inference will be the same regardless, as the evidence he gets doesn't differ between, * I flip, get lucky, and tell Harry heads and * I lie and tell Harry I flipped and got heads or even * I flip, get tails, and tell Harry heads.
3FAWS12y
If you are the sort of person who would do that Harry will assume that you lie if presented with that evidence unless you also successfully fool Harry as to what sort of person you are (and presumably he will default to not trusting you if unsure). Otherwise you are just wasting your time.

Edit: Ah, wait, they can't change their allegiance as targets, can they? Otherwise Zabini wouldn't be able to choose the victor at the end.

Chapter 32: Why didn't they (visibly) use change of allegiance for defense in the second phase? If you turn yourself into a soldier of the enemy, then the enemy will lose a point for shooting you. Thus, everyone should hold allegiance to the enemy except for the exact moments they fire (which would be quite hard, since you'd need to find someone with enemy's allegiance who is not loyal to your team).

So, it should've bee... (read more)

620 comments is very unwieldy, especially when threaded. A new post per chapter would be less likely to cause brains like mine (that is, unlike Eliezer and Harry's, who seem to have brains built like the TARDIS) to go into terminal explosive overload.

I feel almost certain that Harry is living in a computer simulation. I know he ruled it out because he decided the existence of the Time Turner renders the universe non-computable, but how can he be sure that he's actually going backwards in time instead of the universe "simulating going back to the past and computing a different future?"

8Baughn12y
Time-travel doesn't make the universe uncomputable, is the thing. Time-travel makes certain laws of physics uncomputable, but there are any number of equivalent, far more complex sets of laws that would look the same to humans but remain computable - Eliezer's mind is running one, for starters. When writing a simulation, you would use one of those.

Chapter 23: I wonder when Harry will realize that the reason he's an idiot isn't that he doesn't have a perfect emergency kit (though that's important), it's that he doesn't have a gut level understanding that the wizarding world is very dangerous, especially the Malfoys.

0RobinZ12y
I was just thinking along these lines again when I read the July 2 update. Chapter 15: Chapter 26: Chapter 28:

How does all this exactingly correct pronunciation stuff interact with accents, speech impediments, having just been socked in the face, or otherwise having issues with getting exact sounds out?

For that matter, what do mute wizards and witches do? Do they just have to learn to cast everything nonverbally? Or can they cure muteness with magic such that it never comes up?

4alethiophile12y
There's mention in the fifth book of canon that Neville gets a fat lip and is unable to pronounce spells in battle (he ends up just stabbing someone with his wand).
2gwern12y
Wandless magic [http://harrypotter.wikia.com/wiki/Wandless_spell] presumably. (I vaguely recall mention of Eastern wizards relying on gestures and not wands/vocalization, but I'm not sure whether this is canon or fanfic.)

Have you read Harry Potter and the Nightmares of Futures Past [http://www.fanfiction.net/s/2636963/1/Harry_Potter_and_the_Nightmares_of_Futures_Past] ? It mentioned the eastern wizards doing hand gestures thing, and I don't recall the canon books ever talking about that. So if you've read NoFP, you probably got the idea from there.

I did in fact read it after it was linked in the reviews for MoR (either here or on ff.net), so I guess that's where it came from! Well-spotted.

At this point, the precision seems to just be about duration of vowels. I don't know how Harry chose that test. Afaik, spells don't have to be written in the International Phonetic Alphabet [http://en.wikipedia.org/wiki/Ipa].
1LucasSloan12y
He was testing 16 different variants. The vowel duration was only the test we saw in full.

Eliezer previously considered the idea of a cabal of physicists keeping nuclear weapons a secret in this post. The idea turns up again in this chapter of Three Worlds Collide. Any thoughts? Would you feel safer if only super-rich physicists had access to nuclear weapons?

4Baughn13y
Not particularly. Apart from uncertainty of whether that would actually reduce threats in general, in the particular case of nuclear weapons it's relatively easy to argue that their existence has reduced suffering, overall.
4simplicio13y
I'm not sure the temporary peace they bring is worth it considering how they up the ante. Sure, they probably prevented the Cold War getting hot. On the other hand, one nutcase or terrorist can erase all that utility pretty goddam fast. Hallelujah.
1Baughn13y
Right, it's easy to argue the other side too. :-)
1DanArmak13y
Yes, because there are so few super-rich physicists :-)
0JoshuaZ13y
Well, in such a world presumably more physicists would be super-rich. There would be other problems with such a world also. For example, if there are very few people with access to nukes then a first-strike attempt becomes much more plausible. Also, with only a few people knowing about something, the standard problems that come from security though obscurity will start showing up.
0DanArmak13y
In our world, there are various weapons that could be used to kill at least as many people as a nuclear bomb would. GE plague is one, and it's easy to believe that in the near future a competent biologist would be able to engineer a usable bioweapon at home. With that alternative in mind, I would love for GE bioweapons to only be accessible to super-rich biologists. There are fewer super-rich physicists than there are ordinarily rich states who possess nuclear weapons. Plus, 90% of the actual use nuclear weapons get is deterrence, and secret nuclear weapons are useless for that. OTOH, for garage-based first strike capacity nuclear weapons aren't required, there are also bioweapons etc. That's why I'd rather the physicists had a monopoly.
0CronoDAS13y
Hell no!
0DanArmak13y
Why not?
0CronoDAS13y
Who holds the physicists accountable for their actions?
6DanArmak13y
Probably no-one. And today no-one really holds nations with nuclear capabilities accountable. How are physicists any worse? Consider that physicists have fewer potential reasons to use nuclear weapons than do nations, or to go to "war" with one another. If they attacked one another, or third parties, they would not be able to protect themselves from (non-nuclear) retaliation as rulers of nations do, because they wouldn't have large territories and conventional armies. If they won the war, they wouldn't get any economical benefits; their only possible reason for using the nuclear weapons would be to kill some people. I consider that individual people, particularly those who are well-off and have a lot of money to solve problems with, are much less likely to want to kill others than are nations.

Is Harry learning how to lose?

Chp 19 is when Harry went through the ordeal with Quirrell to learn how to lose.

Chp 21 he lost the textbook reading contest with Hermione and acted like a whiny sore loser, suggesting that he hadn't really learned much. He acted like such a brat that I had to assume that he'd failed to learn some basic social skills in his solitary homeschooled childhood (e.g., you should at least act like you've lost gracefully, by congratulating the winner and not complaining).

Chp 32 Harry seems to be trying to goad Draco and Hermione into ... (read more)

2Unnamed12y
Chp 33 provides more support for this take on chp 32. Draco & Hermione threaten to cooperate against Harry if he accepts traitors, Harry openly proclaims that he'll accept traitors and challenges them to cooperate, and Quirrell is surprised by Harry's response. This makes the most sense if Harry is thinking outside the game and seeing his tactic as win-win: either he gets Draco & Hermione to cooperate (win in life), or they fail to cooperate and he has an advantage in the battle (win in the game).

Regarding the author's notes for chapter 32: I assume the complexity class you're looking for at the end there would be something like PromiseNP? Also, the trick really is more general than that, seeing as you can actually use it to do anything in PSPACE.

I should really have mentioned this back in the appropriate chapter, but..

Remember how Harry complains that adding (consistent) time-travel makes the universe uncomputable? Leaving aside how I'm not exactly convinced of that myself, I thought I should point out that such consistent time-travel has recently been experimentally demonstrated.

Have a look at http://arxiv4.library.cornell.edu/abs/1005.2219 . It was published way too late for Harry to read it, unfortunately. :P

2Sniffnoy12y
If I'm reading this right, this isn't an experimental demonstration of time travel, rather, it's a theory of time travel, the predictions of which can be determined experimentally, and an example of such an experiment, to determine what would happen in a grandfather paradox case if the theory is correct.
3Baughn12y
I interpreted it as stating that they had actually performed the experiment, and gotten a positive result. Am I misinterpreting something?
1Sniffnoy12y
As I understand it, their theory is that time travel is like postselection. Hence, to determine what would happen in the case of the grandfather paradox, they set up an equivalent postselection experiment. So if their theory is correct, the results of an actual grandfather paradox experiment would match the results of this simulated-via-postselection one.
0Baughn12y
In what sense is post-selection not time-travel? You've still got the state at time T determined by the state at T+1.
1Sniffnoy12y
Because, if I'm reading this right, they literally manually postselected the results. They didn't come up with some way to get the physics to postselect it for you.
0wedrifid12y
My interpretation matches yours.
0Douglas_Knight12y
The abstract mentions Deutsch November 1991 [http://link.aps.org/doi/10.1103/PhysRevD.44.3197], just a bit too late for Harry. Deutsch is specificaly about quantum mechanics and that the result is computable. He suggests that you could solve hard problems with a CTC, but I don't think he pursues it. I am amused by the caption to figure 5: "Network for finding a fixed point of f?"

Harry's knuckles had gone white on his wand by the time he stopped trying to Transfigure the air in front of his wand into a paperclip. It wouldn't have been safe to Transfigure the paperclip into gas, of course, but Harry didn't see any reason why it would be unsafe the other way around. It just wasn't supposed to be possible. But why not? Air was as real a substance as anything else...

Well, maybe that limitation did make sense. Air was disorganized, all the molecules constantly changing their relation to each other. Maybe you couldn't impose a new form

Shouldn't Slughorn be trying to get Harry into his social circle very soon after Harry's substantial victory over Snape?

6gwern12y
Sure, but how many days have passed? Not very many. And Slughorn is retired. Harry's exploits in books 1-5 are even more impressive than this Harry's maneuvering, and yet look how late on Slughorn is first introduced.

Definitely, especially since Harry should be looking him up and courting him early on! "I'm the boy who lived! Let's have a tea party. We'll invite Draco (not in disrepute yet) and Hermione." I wonder if Harry will start making that sort of move soon. It seems to be the kind of lesson that HP:MoR may like to impart.
2NancyLebovitz12y
It's been a while since I've read the book. I don't know whether Slughorn would be amenable to such a direct approach, or would prefer to make the first move. If the latter, Harry would need to be more subtle.</
