HPMOR (discussion & meta)
Personal Blog

Update: Discussion has moved on to a new thread.

The load more comments links are getting annoying (at least if you're not logged in), so it's time for a new Harry Potter and the Methods of Rationality discussion thread.  We're also approaching the traditional 500-comment mark, but I think that hidden comments provide more appropriate joints to carve these threads at.  So as of chapter 67, this is the place to share your thoughts about Eliezer Yudkowsky's Harry Potter fanfic.

The first 5 discussion threads are on the main page under the harry_potter tag.  Threads 6 and on (including this one) are in the discussion section using its separate tag system.  Also: one, two, three, four, five, six.  The fanfiction.net author page is the central author-controlled HPMOR clearinghouse with links to the RSS feed, pdf version, TV Tropes pages, fan art, and more, and AdeleneDawner has kept an archive of Author's Notes.

As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.

Spoiler Warning:  this thread is full of spoilers.  With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13.  More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it's fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that "Eliezer said X is true" unless you use rot13.

Today I met a relative of mine named Eliezer Yudkowsky. First words out of his mouth: "Oh, it's you! You're the one who ruined my life!"

I also met Avi, who (I was told) used to come over to babysit me, and I would do his math homework for him.

And I was told that at one point during my distant youth, I was holding a camera and kept tilting it, and Uncle David kept telling me "Hold it steady!" without effect, and then Dad said "Hold it in a plane perpendicular to the floor" and that worked.

Just in case anyone was still claiming that my eleven-year-olds are unrealistic.

Just in case anyone was still claiming that my eleven-year-olds are unrealistic.

People still won't buy your character, because reality is unrealistic (TVTropes). Orson Scott Card got the same reactions to Ender (although I can't find the reference now).

It's in the introduction to (later printings of) Ender's Game, starting on page XIX:

For some people, however, the loathing for Ender's Game transcended mere artistic argument. I recall a letter to the editor of Isaac Asimov's Science Fiction Magazine, in which a woman who worked as a guidance counselor for gifted children reported that she had only picked up Ender's Game to read because her son had kept telling her it was a wonderful book. She read it and loathed it. Of course, I wondered what kind of guidance counselor would hold her son's tastes up to public ridicule, but the criticism that left me most flabbergasted was her assertion that my depiction of gifted children was hopelessly unrealistic. They just don't talk like that, she said. They don't think like that.

And it wasn't just her. There have been others with that criticism. Thus I began to realize that, as it is, Ender's Game disturbs some people because it challenges their assumptions about reality. In fact, the novel's very clarity may make it more challenging, simply because the story's vision of the world is so unrelentlessly plain. It was important to her, and to others, to believe that children don't actually thi

1TobyBartels10yThanks!
8CarlShulman10yWhich particular effects were annoying him?
4Eliezer Yudkowsky10yGoogle shadow, of course.
8Nominull10ySome eleven-year-olds might be that way, but if your sample consists mostly of relatives of geniuses, it's going to be pretty skewed, I would think. There's no causal link between Harry and Draco and Hermione and Blaise and... I dunno who else people are claiming is unrealistic. Still, four unrelated genius-level children out of the, I don't know, one hundred first year Hogwarts students? It's not entirely unfair to see that as statistically unlikely, even if theoretically possible.

Keep in mind that Blaise's plan was Dumbledore's.

5Desrtopa10yI don't get the impression that Draco is especially brilliant (for a real eleven year old, he would be, but Eliezer's characters don't act eleven in general,) but rather that he's especially well trained. He might be a one-in-a-hundred intellect, but he's had an education that not one muggle in millions gets. Blaise is clever, but likewise learned from an exceptionally duplicitous mother, and had Dumbledore passing him notes.
3hairyfigment10yHermione of course has great scholarly talents in canon. Harry -- I've seen people argue that he would have been a genius in canon if the abuse didn't warp him, and here he obviously had an excellent environment for developing mental abilities. But Harry does see himself as an anomaly. Some people here (apparently not believing nurture can explain that much) have a theory to account for him. As for Draco and Blaise, we know for a fact the former had extensive training. On a meta level, increasing Harry's intelligence required a smarter Voldemort and thus a smarter Dumbledore. Lucius Malfoy then needed smarts in order to produce a more-or-less canonical starting point for the story. And his erstwhile (?) Lord would not pick an idiot as a servant (not if he could find a way to control a smart minion.) Notice this means that, if MoR!Voldemort affected Harry's intelligence, three out of the four names you mention would have an indirect causal link in-story as well as in reality.
1Vladimir_Nesov10yThey have magic, and they are physically sturdier than Muggles. Maybe they are also on average smarter than Muggles. Which constitutes evidence for Terry Tao being a wizard.
9Desrtopa10yTheir being smarter on average than Muggles doesn't seem particularly well supported by the story so far, except insofar as the average intelligence of characters in the story is raised by virtue of being written by Eliezer.
[-][anonymous]10y 39

Ch. 68 I thought was particularly strong. I find I really enjoy parts of the story that dip into Hermione or Draco's POV, so I'm glad to see more of that.

Ch. 68 also mitigated a negative reaction I'd had to the previous chapter -- watching Harry and Neville wipe out all of Sunshine by themselves, my reaction was a reader was an exasperated "Okay, must we really be bludgeoned with evidence of Harry's manifest superiority to all the other canon characters? It's getting to be a bit much." So for the next chapter to dip into Hermione's head when she's having the exact same thoughts--it helps a lot to counter my objection, because it shows a self-awareness in the text. It seems to promise we're going somewhere with all this.

I also think it's kind of interesting to contrast MoR!Hermione with the canon character. Canon Hermione was pretty much totally okay with her part as a supporting player in Harry's quest. There's this exchange in the first book:

'Harry — you're a great wizard, you know.' 'I'm not as good as you,' said Harry, very embarrassed, as she let go of him. 'Me! Books! And cleverness! There are more important things – friendship and bravery and – oh Harry – be careful... (read more)

Good comment. Upvoted.

I've been wary of the way Hermione was presented so far. A month ago I was involved in a feminist discussion of literature, and more than one person expressed an explicit lack of interest in stories about "white dudes being responsible for saving the world." Upon reading it I thought back to MoR. I know there are constraints on the story that Eliezer doesn't control, except for choosing to have written the story in the first place. Harry's already a white dude responsible for saving the world, and adding SuperRationalist to his resume is going to inherently blow Hermione out of the water in her own sphere of influence.

At the time of the conversation about feminist literature (or lackthereof) we were at chapter 63. Hermione had yet to do anything significant. There were enough hints that Eliezer was aware of the issues facing her, both as a character in general and as "the Girl™" in particular, but those issues had merely been mentioned, not addressed. She had attempted to regain her personhood by becoming the general, and then lost everything she gained when she kissed Harry.

I had a vague faith that Eliezer would eventually address it someh... (read more)

9Eliezer Yudkowsky10yHigh probability this comment had something to do with the surprise creation of SPHEW.
2Raemon10yHeh. As I noted elsewhere, whatever your exact motivations were, I thought it was pretty awesome.
8Eliezer Yudkowsky10yOh, it's a critique all right, but it's not a feminist critique. One free karma point if you can guess what it's a critique of.
[-][anonymous]10y 24

I have no idea if this was intended, but reading the chapter reminded me strongly of these two posts.

On the one hand, it is possible that Harry has simply gone on to a level where Hermione cannot follow. This suspicion, naturally, is devastating to her ego, but it's part of what she's grappling with now. And that moment is completely part of the archetypal Nerd Journey--for a lot of us it happens in college. All our lives we've always been the smartest kid at school, but suddenly we go to a much bigger school and we're confronted for the first time with the reality that we are maybe not the colossal geniuses our high school teachers and our parents always told us we were. We realize there is a level above our own. That moment can be very difficult.

But at the same time, as Hermione grapples with this realization, she's wondering if she can go any higher, and she's being told: No, because you don't have the aura of destiny.

Of course this is a fantasy story, a world with magic, and there is a special prophecy that names Harry and does not name Hermione. But I think she's right to object when Dumbledore and McGonagall refuse to give her the kind of help they're giving Harry, merely because it's not her name on the title of the story.

7[anonymous]10yThe hero archetype?
8NancyLebovitz10yI think it's something like that-- it's a critique of the idea that a hero accretes followers, and the followers didn't have anything else they wanted to do with their lives. It may also be a critique of the idea of wanting to be an individual in a fairly loose context when sometimes it's necessary to get more involved to do what's important.
4David_Gerard10yHumans accumulate followers. It's disconcerting to realise just how easy it is to accumulate followers - even from those who'd make quite good leaders themselves - just by telling people to do things and looking vaguely like you know where you're going. This is some sort of human universal.
3NancyLebovitz10yFair point. On the other hand, Sam Gamgee following Frodo is probably an oversimplification of the process, and Hermione:MOR is a good counterbalancing image.
4Raemon10yHa. I have no idea what's intended to be critiqued here, but Society for the Promotion of Heroic Equality for Witches is hilarious. Perfectly works alongside Canon Hermione (It even spells out S.P.H.E.W, I assume intentionally). And whatever your intentions, I think it does a decent job of accomplishing the actual goals of feminism while lampooning some of the more ridiculous efforts. Props to Dumbledore.
4Raemon10yI'm assuming that "bad writing" is too broad an answer, whether or not the more precise answer happens to fall within it. The obvious answer is a tendency (both in writing and among humanity in general) to latch onto figureheads/heroes and give them disproportionate amounts of praise and expectations. But that seems too obvious. For the record, I'm defining feminism in a fairly broad "women should generally be treated equally to men, for the same reason that people should generally be treated as equal" sort of way. Not that men and women are completely identical or any other specific policies that you might or might not agree with. I know you have some concerns about gender politics, although I don't know what they are. (If the answer was a critique against "objectification of people in general", I'd consider feminism a subsidiary of that)
3benelliott10yMy guess, its about the other side of the Tsuyoku Naritai coin. An obvious implication of "run your fastest, you shouldn't have to feel bad if get ahead of other people" is "if other people run their fastest and get ahead of you, don't resent them for it". The same point is also made briefly by Draco's internal narration in Ch67.
3ArisKatsaris10yA meritocratic critique of egalitarianism?
3Barry_Cotter10yAgency; the idea that one person really can make a massive difference, whether that be all by their lonesome, or by setting things in motion or leadershio.

Eliezer's stories are full of people who make a massive difference. That'd be a weird thing for Eliezer to criticize.

7Eneasz10yI think it's more a critique that EVERYONE can be that one person. Obviously they can't. Not necessarily just because the aren't the best either. Support staff is critical. Logistically it's impossible for everyone to be the hero because a hero without a support staff is just a dude waving a lightsaber around on his uncle's moisture farm.
1LucasSloan10yThe concept of the "chosen one."
0tondwalkar8yA satirization of the mahou shoujo genre? Complete with costumes! An aside, they way you used "feminist critique" isn't the standard meaning of the phrase. A feminist critique would be a critique from a feminist framework, not a critique of feminism, much like a Bayesian critique of something would argue that it's fallaciously reasoning about probabilities.
3Eliezer Yudkowsky8yThat is what I mean; HPMOR's Hermione represents a critique of something, but not a "critique from a feminist framework" of that thing.
0[anonymous]10yThe idea that heroism is intrinsic, rather than something that people can be prodded into or pushed out of?
0wedrifid10yJumping in from the future... it looks like Harry has grown out of this! It kind of freaked Hermione out. :S
0[anonymous]10yCanon!Hermione is so much stronger than canon!Harry that she has to encourage him, yes. Calling this "yielding gracefully" strikes me as exaggeration.

If you want to figure out the James' Rock thing yourself, you should probably stop reading now.

I read this in ch58

Luckily - well, not luckily, luck had nothing to do with it - conscientiously, Harry had practiced Transfiguration for an extra hour every day, to the point where he was ahead of even Hermione in that one class; he'd practiced partial Transfiguration to the point where his thoughts had begun taking the true universe for granted, so that it required only slightly more effort to keep its timeless quantum nature in mind, even as he kept a firm mental separation between the concept of Form and the concept of substance.

And the problem with that art having become so routine...

...was that Harry could think about other things while he was doing it.

and (putting my contrarian nature to good use) thought, the other reason he was good at it was, he concentrated on maintaining his transfigured ring stone all the time. Then I realized that's all thanks to Dumbledore and I started to wonder if it was intentional. In search of clues I reread ch17, specifically the part where Harry got the rock, and then went on to read the Lily's potion book part because it seemed related. That's w... (read more)

7rdb10yIf there is a training effect in increasing magical strength, and or improving concentration, keeping the rock transfigured works that way too, without being Transfiguration specific. Quirrel's armies help too - would normal classroom activity exhaust magic that much? Harry could try a controlled experiment over the Easter holiday if he thinks about it. With McGonagall's permission, ask his classmates to keep a loop of cord transfigured into an unobtrusive platinum toe ring (or more than one) over the holiday when they're not otherwise allowed to use magic. Then compare deltas in transfiguration scores on the next test between those who did & didn't attempt it. Is Harry getting letters back from his parents? He doesn't yet seem to be thinking about measuring magical strength, but a tool to compare would permit some kind of scale - if it could use embodied magic in magic items as markers. That could argue for faster access to later year charms. Similarly of pre-electronic tech that may be useful, that his parents may remember. (Slide rules, Curta calcs, Microfiche & hand held readers, ...)
0bigjeff510yThe toe ring test probably wouldn't fly, the Ministry detects underage magic outside of the vicinity of Hogwarts and responds harshly.
1wnoise10yIn canon, the detection spells can't even tell the difference between Dobby's use of magic and Harry's. Telling the difference between a kid's magic and his parents' would appear to be even harder. For the wizarding kids, if their use of magic can't be told apart from their parents, there would be no way to sanction them. At that point the detection spells are only effective for muggle-borns. I'm not aware of any in-canon detection of children living with magical parents. (This would also let the wizarding families train their kids even when not at school, as a convenient way to bolster their status).
0TobyBartels10yI'm pretty sure that I read somewhere that Wizarding families themselves are expected to keep an eye on their children when at home.
1orthonormal10yPlausible, but that can't be the only reason for the rock; too big a deal [http://tvtropes.org/pmwiki/pmwiki.php/Main/ptitlexn9xzsjd5fif] was made of it at the time.
0bigjeff510yYou do have to bear in mind that Dumbledore is quite crazy (in a purposeful sort of way). It wouldn't surprise me if he simply found a rock that James Potter had kicked around for a while, and on that basis claimed it was "James's Favorite Rock". Then the rock became a way to force Harry to improve his Transfiguration skills in a huge way. Also, as rdb notes below, that kind of concentration simply must have bleed over into other types of magic.
0thomblake10yYes, several people I know in-person had the same take-away from the rock transfiguration exercise when it was first introduced.
0major10yGood, I'm probably no crazier then them, than. Did they also guess Quirrellmort's endgame plans before the hiatus? (Well, in retrospect, it was guessable way before that.)

As of 4:17am PDT, HPMOR is the #1 most-reviewed Harry Potter fanfiction on the entire Internet.

8cultureulterior10yHow did the pair writing go? I'd be interested in trying something like that myself.
3Psy-Kosh10yCongratulations! (Now, you must aspire to make it the fanfic for which the reviews themselves are most reviewed!)
1wedrifid10yCongrats! How far to go until it is the most reviewed fanfiction on the entire internet?
1Eliezer Yudkowsky10yThere was a Twilight fanfiction with 55,000 reviews but it seems to have disappeared off FF.net; I don't know what was #2.
0LauralH8y...and that Fanfic is now 50 Shades of Gray.
0Nisan10yHooray!

Hi Eliezer, one minor issue I have with this (awesome) story is the punctuation. In particular, you often use commas when other punctuation might read better. Here are a few examples from chapter 68:

1.

Hermione wasn't feeling very nice right now, or Good either, there was a hot ball of anger...

Would read better as:

Hermione wasn't feeling very nice right now, or Good either. There was a hot ball of anger...


2.

Would read better as:

Hermione began speaking. Despite her newfound resolution, her voice still stumbled a little with nervousness as...


3.

"That -" Harry's voice said urgently, she wasn't looking at him but his voice sounded like he had his head turned toward her. "That was...

Would read better as:

"That -" Harry's voice said urgently - she wasn't looking at him but his voice sounded like he had turned toward her - "that was...


I get the impression that you often do this in order to create a sense of rushing/urgency, and it mostly works, but other times it reads awkwardly. It's particularly noticeable at the beginnin... (read more)

4TobyBartels10yI'm no expert, but I'm confident in my own knowledge here; your edits are more correct by the prescriptive standards of English. They also read better to me too, although may I suggest some semicolons sometimes?
6Manfred10yI agree that semicolons are awesome, and one would probably be the best choice for sentence two.
1free_rip10yBoth colons and semi-colons are known to break the flow of writing. Dashes generally flow better than semi-colons. This is something I've found after writing many pieces (often with lots of semi-colons, which my natural style has a lot of) on a peer review writing-site and having reviewers tell me - 'x sentence doesn't flow well' for basically every sentence with a semi-colon. They work better in non-fic writing, where the flow can be more formal.
1syllogism10yA substantial disadvantage of semi-colons is simply that they're rare. If a small but significant portion of your readers don't read them as you intend you're better off finding another way. It's a pity though, because if I were writing for perfect clones of me, they'd often be the best choice.
1TobyBartels10yI use semicolons a lot more when writing on Less Wrong (and other places where intelligence is high) than on many other places.

Ch. 68:

Hermione wears makeup? On a regular basis?! Has this been mentioned before, in MoR or canon? Seems somewhat-to-very out of character to me.

ETA: Eliezer has now removed the reference.

8Sheaman377310yI was also surprised when I read this line. I wouldn't have thought it typical of her at all.
[-][anonymous]10y 12

Yeah, I blinked a bit at that too. In canon she can't be bothered to use hair product (even though she likes the effect on her frizzy hair) because it takes too much time to put on, so it seems probable that makeup is in the same category. I could maybe see a light lip gloss, if Hogwarts is dry and her lips tend to chap.

On the other hand, Emma Watson obviously wears makeup, so perhaps this is movieverse Hermione.

Lastly, I know this opinion makes me, like, ninety years old and Amish to boot, but twelve is too young for make-up.

7free_rip10yI'm 16, female, atheist and don't wear make-up. There's nothing old-fashioned about it - it's just practical for the school years.
8[anonymous]10yIt's the notion that twelve is too young that I suspect is out-of-date, not the notion that makeup is generally impractical -- lots of women of all ages don't wear any. I don't in my everyday routine, although I do if I'm dressing up.
1Eneasz10yI agree. Isn't the primary purpose of make-up the attraction of a mate? I know many kids start experimenting around that age, but that kinda weirds me out.
2David_Gerard10yWe have teenagers who've worn makeup since 14, but that's because they had the Kevyn Aucoin [http://en.wikipedia.org/wiki/Kevyn_Aucoin] books and learnt it as a form of dressing up well. Aucoin's books are the books on how to do makeup well and should be regarded as standard texts on the subject.
2Unnamed10yShe's already kissed a boy and gone on a date.
0bogdanb10yIt’s the “primary purpose” in the sense that it’s also the primary purpose of jewelry and pretty clothes. Which I kind of doubt in general, although of course it could be true in particular cases.
3ArisKatsaris10yYeah, that was weird for me too. Seems both uncanonical and out-of-character.
3Raemon10yAdd me to this list of reactions.

Upvote this if you think neither.

Given the number of people struggling with the "Azkaban Saturday" timeline, I thought I'd have a go at mapping it out and uploading the result to Google Documents. If anyone's got any corrections, feel free to say so.

Something I've mentioned before, but usually as part of a reply to something else: I strongly believe that the work would benefit from being officially divided into different books. Chapter 63 was incredibly cathartic to read, partly because it was a very intense chapter that resolved a lot of stuff, but partly because at the time, we knew a hiatus was coming and that it was the End™ of a particular section. That, in combination with the fact it touched upon every single plot thread, made it feel more potent. And the PDF version, at that time, was a little over 1000 pages, which is about right for a Harry Potter book.

It's also a daunting to get new people to read something when there's a bajillion chapters. I don't know if you're planning for two parts or three, but presumably there will be at least 120 chapters when this is done, if not 180+. I had better luck getting new people to read it when I specifically said "book 1 just finished, I can give you the PDF of that," and I think that's in part because "one book" is a friendlier way of measuring length than some large number of pages.

Fanfiction.net might have specific rules, or you might want to just keep thin... (read more)

3benelliott10yFunny, I have the exact opposite reaction. I quite enjoy getting into a story by reading through a long archive and I'm often put off by small page-counts, since I know that even if I like it I'll just hit a frustrating stop in the near future.
1Raemon10yMy personal criteria is "likelihood of being finished" regardless of how long it is. Part of what I like about book 1 being a separate PDF is that no matter how long it is till the next part is done, you have one section that you can point to and say "finished."
0benelliott10yI also try to judge by that, although its not always easy to do so. I also like the idea of Book 1 being separate, for many of the other reasons you gave.
2humpolec10yTo go with the TV series analogy proposed by Eliezer, maybe it could be an end of Season 1?
6Raemon10yYeah, that's exactly how I'd think about it. I actually think that usually, books should be turned into TV shows, not movies. A thousand pages of book translates into approximately a thousand minutes, so making a movie requires you to gut the book down to the equivalent of 200-300 pages, whereas making a tv series would allow you to actually flesh things out further, giving the director time to actually do something interesting with the material. I firmly believe Harry Potter should have been a TV show, not a movie. At least from an artistic, if not economic standpoint.
2hairyfigment10yBack when the story ended with the "Humanism" arc, I told someone that a hypothetical publisher could reasonably treat it as the end of Volume One. If we can actually agree on possible ending points, then it makes sense to at least note these at the end of the chapter (somewhat like the sub-books within The Fellowship of the Ring etc.)

Ch 69

"Excuse (gasp) me," she said, "can you (gasp) Unjellyfy my legs?"

I can't believe I couldn't figure out the countercurse was just "Unjellify!" (ETA: Act I, Part 4, 9:07, if anybody cares). (Edit June 17: link changed to be more precise; it used to be this.)

0trlkly9yAnd what does some people eating donuts on a string have to do with anything you said? Is YouTube reusing hashes from removed videos or something?
0TobyBartels9yI believe that I was intending to link to a playlist, whereas I actually linked to the YouTube user who posted that playlist, and this user is now featuring an unrelated video. Here's a link to the playlist: https://www.youtube.com/playlist?list=PLC76BE906C9D83A3A [https://www.youtube.com/playlist?list=PLC76BE906C9D83A3A]
0Manfred10yIf only I could vote this up twice.
2TheOtherDave10yWell, you certainly can... just create another account. I don't recommend it, though.

Ch. 69:

Currently she was being referred to as the Sparkly Unicorn Princess of the Noble and Most Ancient House of Sparklypoo.

Reference.

Animate armor.

As Dumbledore demonstrates in Order of the Phoenix, any spell, even Avada Kadavra, can be blocked by a temporarily animate statue (the spell "kills" the statue instead). Which actually annoyed me when I read it, since that implies wizards could imbue each layer of their clothing with intelligence before a battle, and gain a bunch of extra lives.

(Having your breastplate shout taunts at your enemy also frees you up to focus on fighting.)

It wasn't the animatedness of the statue that made it block Avada Kedavra, it was that it was a huge block of solid stuff. Voldemort in the same sequence crafted a physical shield for himself, though he didn't need to block any Avada Kedavras (as Dumbledore didn't cast any).

Of course, imbuing your clothing with intelligence so it will absorb killing curses has some truly horrifying moral implications.

8sketerpot10yDoes Avada Kedavra require that its victim be intelligent, or just alive? If it's the latter, then a wizard could presumably turn a leather jacket into a flesh golem or something. It's gruesome enough that there would probably be an old book giving detailed instructions, with horrible illustrations.
8FAWS10yI believe Bartemius Crouch Jr. demonstrates the curse by casting it on a spider so intelligence is not required in the books, but this seems like something that might be changed in the fanfic.

Quirrell distinguished himself early on in the fic as saying that the Killing Curse was a spell that solved many problems. He also said (ch 16):

The Killing Curse is unblockable, unstoppable, and works every single time on anything with a brain.

1benelliott10yDidn't think of that. I suspect that the exact requirement amounts to having a 'soul', whatever that means.
7DanielLC10yOnly if you're death-averse. I figure intelligence for a little bit is better than no intelligence at all. Besides, you cease to be intelligent every time you fall asleep. People never seem to worry about the moral implications of that. I admit Harry is death-averse. I suppose he just never thought about sleep.

Comparing sleep to death for intelligence is like comparing a screensaver to dismantling for a computer. The brain is still very active during sleep, external stimuli can still be recognized, and sleep isn't a permanent condition. I don't see how such a comparison is meaningful for discussing intelligence.

2DanielLC10yAll those things except permanence are true of animals, or for that matter, a computer. Permanence causes a lot of paradoxes. For example, if you "kill" someone in their sleep, they never wake up, so it was permanent. That is, unless you start using counterfactuals, and talk about if they could have been woken up. In that case, they still can. It's not completely impossible, just really unlikely. But if you were dead set on killing them once they went to sleep, it would be really unlikely for them to wake up from that. Also, if they stop being intelligent, it becomes impossible to follow what "them" is. Intelligence stops. Intelligence starts. Who's to say it's the same one?
8Vaniver10yhides face behind hands reveals PEEKABOO!
1Dreaded_Anomaly10yThat's a weak use of permanence. Nothing about the process of sleep requires that it be permanent, so sleep does not have the inherent property of permanence. Sometimes, people incidentally never wake from sleep, but that's not permanence in the way that death is inherently permanent. I don't agree that we stop being intelligent when we sleep. You continue to assert this, but without supporting it. Again: Also, if intelligence "stops" and "starts" from the same physical generator, i.e. the brain, (which isn't what happens with sleep) then it is the same one [http://lesswrong.com/lw/r9/quantum_mechanics_and_personal_identity/]. (Edited to add article link.)
3DanielLC10yWhat makes it inherently permanent? The only difference between sleep, cryostasis, and being shot in the head is how likely you are to be revived. It's never certain, and it's never impossible. Death is permanent by definition, but that just means we're never quite certain anybody is dead. Pretty much everyone's brain is made of the same quarks and leptons, so the same physical generator doesn't exactly narrow it down any. I would explain what I mean by that, but the link you have already does it.
0benelliott10yIf they have the same memories and the same personality then its still them.
0DanielLC10yBut then you're not the same person "you" were a year ago, and it's possible for you to be two people at once. Also, that means that it's impossible to ever tell if you're dead. Even without some way of working out who you were, another you could start by complete coincidence.
2bigjeff510yThe Sorting Hat disagreed. It seemed pretty pissed at Harry for accidentally making it sentient, which then meant Harry would be forced to kill it by removing the source if the hat's sentience.
1TobyBartels10yYou could imbue an item with intelligence and the desire to die gloriously in battle. In response, DanielLC seems to take it for granted that the rule of morality is "Do to others what you would have them do to you.", which is not bad as a rule of thumb, but leads to irreconcilable conflict when applied by people with different preferences (such as intelligence, even for a brief period, vs continuing to survive, once intelligence exists). The real rule should be "Do to others what they would have you do to them.". Since your clothing has no preferences before imbuing it with intelligence, anything that you do to it is (directly) morally neutral. As for the indirect effect that it's liable to be horribly killed, the morality of that depends entirely on what its preferences are after it is imbued with intelligence. All that said, I didn't read the statues in OotP as having intelligence at all. Edit: I forgot to state the correction to the Golden Rule above! Fixed. (Also minor grammar fix and removing the false reference to Dreaded Anomaly.)
0David_Gerard10yAnd noting, of course, that this precise issue comes up when Harry has accidentally made the Sorting Hat sentient.
0JamesAndrix10yWould it also be moral to genetically engineer a human so that it becomes suicidal as a teenager?
0TobyBartels10yIt would be immoral to genetically engineer suicidal depression, and it would be immoral to engineer the desire to die in this society, where it cannot easily be fulfilled. But imagine that puberty, instead of leading people to want to have sex, led us (or some of us) to want to die. While this might be as bad as puberty currently is, with new hormones and great confusion, hopefully a competent genetic engineer would actually make it better. No depression here, but looking forward to becoming an adult, with all that this entails. Presumably the engineer even has some purpose in mind, but even if not, I'm sure that society is more than capable of making one up. There must already be a science fiction story out there with this premise, but I don't know one.
-1David_Allen10yIt would be immoral to engineer the desire to die in this society, where it is considered immoral to make people want to kill themselves.
0Dreaded_Anomaly10yI haven't commented on the morality of the issue at all, just the comparison of death to sleep.
0TobyBartels10ySorry, the opposing moral viewpoint against which Daniel argues is actually Daniel's interpretation of Harry, not you. I've edited my comment.

Ch 68

feeling a lot like a sad little bug that had just been squished

Trust me, Hermione, you're still much better off than her.

I just figured out a possible bit of twisty logic while listening to the podcast that I didn't notice on first read through.

I've spoilered this entire thing even though I probably don't need to, just so that you can can figure it out yourself If you want. I think it explains Dumbledore's otherwise incomprehensible behavior in chapter 17.

I'm fairly certain that being cryptic or condescending is not really the preferred tone around here, though cryptic would be understandable if you actually have insider information that you're not free to share.

Upvote this if you think MoR has been getting better lately.

ch68:

Hermione is very much correct. If she wants to play the hero, she needs to level up.

Hermione Skills- photographic memory, high intelligence, fast learner, high level of spell casting ability. No Patronus capability (although her minions might) Minions - several capable Sunshine luitenents, Ms. McGonigal (not very forthcoming with aid) Magic items - magic bag of holding

Harry Skills - high intelligence. Natural Occlumens. Patronus 2.0 capability. Partial Transfiguration capability. Rational thinking and scientific methods. Highly intuitive with lateral thinking. Knowledge of various Muggle technologies. Parseltongue language Minions/Allies - Chaos Lieutenant Longbottom, Lesath Lestrange, Bella Lestrange, Prof. Quirrell, Prof. Dumbeldor (not very forthcoming with aid), Prof. McGonagal (somewhat forthcoming with aid), Fawkes (?), Santa (?) Magic / Items - Deathly Hallow Cloak, Time Turner, Wealth (limited access), Chest of holding, Bag of holding, various Muggle tech artifacts (batteries, arc welder, ...)

Draco Skills – high intelligence. Patronus. Learning rational thinking and scientific methods. Trained manipulator.
Minions / Allies – Lucius Malfoy, Prof. Snape, P... (read more)

9dclayh10yFor Draco, you forgot Knowledge: wizard society and Status: Noble and Most Ancient House. ETA: And Status: Boy-Who-Lived for Harry, of course.
9wedrifid10yI like this strategizing. I'd actually like to see a Hermione and the Methods of Rationality spinoff. Like the HP one only with less of Harry confusing clever and arrogant with rational (unless Harry has changed his personality in the last 20 or so chapters since I tired of him). Of course, with all Hermione's leveling up she still will not have a: Neville is badass.
7[anonymous]10yVery true. But hey, you know who Hermione does have, in her Allies column? Harry Potter. She should get Harry's help with her heroine project. He certainly wouldn't try to hold her back like Dumbledore and McGonagall. The only difficulty would be explaining her problem to him in a way that he could understand -- but once he did understand it, he'd want to help and he'd probably be good at it, too.
2endoself10yHarry doesn't exactly strike me as psychologically prepared for this particular revelation.
9derefr10yHe's quite prepared in a Hero's Journey sense, though. In Harry's own mind, he has lost his mentor. Thus, he is now free to be a mentor. And what better way to grow, as a Hero and über-rationalist, than to teach others to do what you do? Of course, Harry would say that he's already doing that with Draco—but in the same way that he usually holds back his near-mode instrumental-rationalist dark side, he's holding back the kind of insights that Draco would need to think the way Harry thinks; Harry is training Draco to be a scientist, but not an instrumental rationalist, and therefore, in the context of the story, not a Hero. (To put it another way: Draco will never one-box. He's a virtue-ethicist who is more concerned with "rationality" as just another virtue than with winning per se.) Mentoring Hermione would be an entirely different matter: he would basically have to instill a dark side into her. Quirrel taught Harry how to lose—Harry would have to teach Hermione how to win. If Eliezer has planned MoR as a five-act heroic fantasy, it will probably go like this; usually, in a five-act form, acts 4 and 5 mirror the character developments of the Hero in 2 and 3 in another character, for the purposes of re-examining the (developed, and now mostly stagnant) Hero's growth and revealing by juxtaposition what using that particular character as Hero brought to the journey. It seems more likely to be a three-act form at this point, though, with Azkaban as the central, act 2 ordeal. That's not to say the story is more than half-over already, though; Harry has just found his motivation for acting instead of reacting (to change the magical world such that Azkaban is no longer a part of it.)
7gjm10yThat must be the first time anyone has ever called Draco Malfoy a virtue ethicist. Probably the last, too.
6TobyBartels10yJust because his values don't match yours doesn't mean that he's not ethical. Whether for good or evil, evarybody in canon is a virtue ethicist. (Presumably because Rowling knows no other ethics.)
5gjm10yFor the avoidance of doubt, I wasn't disagreeing that one could categorize Draco that way. I just thought the incongruity of it was striking. (To me, canon!Voldemort doesn't seem like much of a virtue ethicist even in the relevantly expanded sense. More of a consequentialist.)
4wedrifid10yI had the same impression. I think it was Eliezer's-characaturization-of-canon!Voldemort that was the virtue ethicist. Voldemort harnessed, encouraged and exploited a form of virtue ethics in others to reinforce his own power. Tom Riddle was perhaps more of a virtue ethicist. As they say, power corrupts - it even corrupts away virtue systems that were fairly abominable to begin with. I did upvote the grandparent despite this possible exception.
3Desrtopa10yHow so?
3Desrtopa10yHermione knows how to win. She won the first mock battle quite resoundingly. She doesn't necessarily know how to hurt people for the greater good though.
3Normal_Anomaly10yI hope it plays out like this, at least in part. The bits early in the book with Harry teaching Draco were fun. Draco may have already had the instrumental rationality part; certainly he was on a higher level instrumentally than epistemically. He had already had tutors in influencing people, he didn't have an akrasia problem, and he grew up in a culture of "find out what you want and go get it". Also, did you mean "Draco will never one-box?"
1derefr10yEr, yes, edited.
1TobyBartels10yWell, he's had some lessons to clarify the difference between clever arrogance and rationality within some of those chapters.
7DanArmak10yHermoine right now doesn't have a goal. In a story, the strength of a protagonist is proportional to the importance of their goal or the power of their enemies. Tsuikou Naritai won't work if all she wants is not to be weaker than Harry.
4cousin_it10yWhy would she do all this? Just to compete with Harry? She has no sacred quest, remember.
4Sheaman377310yTo be herself in the only way she can? To get out from under Harry's shadow? To not belong to him? She has expressed a desire for all of these.
3Acrinoe10yI just thought of a potential tactical trick for any of the three acting Generals. * bringing some bludgers jinxed to target enemy Generals/Officers/fodder Also, too bad neither of the Weasley twins could have been recruited. (I'm not sure if the existence of the map is known to anyone besides the twins) The Marauder's Map would have been an ideal tool for any Army to outflank, deny ambush, and execute precisely timed manuevers.
3CronoDAS10yFreudian slip? ;)
0Desrtopa10yAcquire, perhaps, but she has fewer funds available to her than Draco or Harry, and anything she's capable of enchanting as a first year wouldn't be especially worthwhile on the scale of magical items.
-1Sheaman377310yIf you are speaking strictly of the Battle Magic armies, have you forgotten: from chapter thirty-one?
0Acrinoe10yHmmm, I did forget about that. Still, magic items would be useful for any other hero quests that might come her way. Harry has certainly made full use of all the tools at his disposal outside of the battlegrounds.

through chp 70

I'm surprised that Harry hasn't tried to learn everything he can about wizarding history, wizarding society, and everyone who's important in the wizarding world. Since before he got to Hogwarts he's thought that he would have a major role in the wizarding world, possibly very soon. He needs to learn about how the wizarding world works, what problems it has that need solving, what good things need protecting, what obstacles could get in his way, what resources there are to draw on, what traps to avoid, who his potential enemies are and how they can be dealt with, and who his potential allies are and how he can win them over.

He's destined by prophecy to fight the Dark Lord (as he learned in chp 6), so you might think that Harry would be using every method available to learn as much as possible about Voldemort, but as far as we know he hasn't been doing that. Dumbledore is one of the most important people in Magical Britain and one of the main people shaping Harry's life, but we know that Harry didn't make much of an effort to learn about Dumbledore (chp 46). He ought to be learning what he can about Grindelwald's war, the Ministry of Magic, Quirrell, Lucius Malfoy, ... (read more)

8Nominull10yHarry canonically disdains "people stuff", and while some of that may be an act for Draco, it does seem in character for him to be more interested in the sciences than the humanities, more interested in learning the rules by which magic operates than facts about the past actions of people who have operated it. As I recall, the only reason he knows so much about the historical decline of Slytherin House is that it came up in the course of his research into the Patronus Charm.

Anyways, one post someone made someone made there was kinda interesting: with the Transfiguration rules being as strict as they are, deliberately breaking those rules seems like a pretty broken combat technique if you were to use them to create biological weapon-ish things. Do wizards simply anticipate that and set up appropriate charms for defense, or what? Given how strict the rules are, it's clear that Harry would NOT be the first person to think of that sort of thing.

This chapter was fun. I'd have liked somewhat better foreshadowing in regards to "what exactly is capable of blocking a magic spell?" though.

I've wondered if it would be a good idea to transfigure some antimatter (Or about 50 kg of uranium if you can transfigure that much) if you ever end up near Voldemort and a bunch of death eaters.

Come to think of it, use Imperious to make other people become your suicide bombers.

That reminds me of wondering why nobody ever made an Imperius virus where they just have each person cast it again.

4drethelin10yAs far as antimatter goes, considering how hard it was to partially transfigure, I Imagine it would be impossible to craft something foreign to most people's understanding without a lot of practice, and anyone who tried to practice would explode the first time they succeeded. I can't recall If there's a canon limitation on Imperius curses, but I imagine they are strictly limited in MORverse simply because if they weren't the entire wizarding world would constantly be suffering from constant control of everyone by everyone.
2Raemon10yOh god I love your Imperius idea. Although the sense I get is that Imperius is very hard to cast and powerful wizards can resist, so a) it wouldn't necessarily be an effective virus, b) it might be pretty easy to notice and then counter, if you were too obvious about it.
5Sheaman377310yNot to mention, if you lost one person, then everyone they infected, and those they infected, ad nauseum, would be released. You could try to mitigate that by having overlapping vectors of infection, but I'm not sure how someone would react to having multiple Imperiuses cast on them.
9Raemon10yGranted, the way this was accomplished in the actual story was by Imperiusing people who were poor wizards but politically powerful, to effectively gain control of large swaths of the population with minimal effort. Which is probably a better idea in the first place. Still, cool concept.
5benelliott10yI'm surprised Quirrel hasn't mentioned something like that in his arguments against democracy. It's possible that rule by the strong really would be safer for wizards.
3Raemon10yHe actually did make this point to Harry.
1[anonymous]10yThe Imperius virus is a brilliant idea, although the caster of the curse has to spend at least some mental energy giving directions to the victim, so there might be a limit to how many victims could be chained from the initial casting. A direct line seems to work just fine--there are canonical instances of Imperiused characters going on to place others under the curse--but I think a tree with many branches would not work.
3Normal_Anomaly10yI think the main problem is that you'd probably take yourself out too.
8Manfred10yBubble-head charm.
2Raemon10yWas my post moderated? A chunk is gone that I don't recall editing. If so, I'd appreciate at least a notification, let alone explanation why.
0Pavitra10yIs it possible there was a bug, or that you misremembered? Edit it back in and see if it re-disappears.
1Raemon10yAt this point I think I just deleted a section by accident when I edited, but by now I don't care about it that much.

Chapter 67 was a lot of fun, but why was everyone just standing around long enough to have big speeches, watch individual duels, etc? Haven't they read their TVTropes? ;)

edit: Also, I'm not sure how it was meant, but Daphne seemed more like she was under a literal spell than a figurative one, given that her crush reached sanity-compromising levels so quickly. Or was it supposed to be a long-running thing?

From Harry's POV,

  1. becoming more serious has made him less serious about battles, so he's willing to slightly hurt their chances of winning in order to make the battle more awesome and fun
  2. he's especially willing to let Neville be awesome, since Neville's development is one of his projects
  3. Harry & Neville don't really have to defeat the entire Sunshine army, they just need to stall them while the rest of Chaos defeats Dragon (this is conveyed through Draco's thoughts), so pausing for a dramatic duel might actually help Chaos's chances

Sunshine was probably glad to have a chance to defeat half of the army that they were facing while only putting one soldier at risk.

0ShardPhoenix10yI would have assumed that the bulk of the Sunshines as whole would have at least kept trying stuff (and maybe hit one of them in the face with Somnium) rather than become passive so quickly.
7Sheaman377310yThe Knights of Chaos are covered from head to toe in the gray cloth, while the rest of the officers in Chaos are only wearing breastplates. It's probable that their faces are not protected, but Sunshine lacks the visual clues that Dragon Army has to make that leap. Besides, they're wee ickle firsties. Their magical reserves are tiny, it could be that many of them aren't attacking in hopes that someone will figure out the trick and then they wouldn't be useless because they blew all of their magic. Or they're currently scared sheep terrified of the invincible Knights of Chaos. Who knows?
5knb10yI assumed it was because none of them knew how to hit Harry, and Potter just wanted to watch a lightsaber duel. If any individual Sunny had tried to hit him with a Somnium, they knew it would probably fail, and Harry would probably curse them. Sanity-compromising? Because she cast a complicated spell during a play-fight?
2Dufaer10yAlso, everyone seems to be shouting their incantations, which seems just dumb. Harry could have also just Somniumed Daphne, after she has reflected his first Stunner and was currently cumbersomely battling Neville – it would cost him just the magical cost of a Sleep Hex itself. Instead he risks Neville getting heavily fatigued or even stunned and chats on.
8Sheaman377310yAgreed, but they're first years. Plus, I got the impression that the dueling incantations were shouted for effect, and that Stupefy was such a large spell for them that they couldn't spare the concentration not to shout, that in fact they needed to shout in order to generate the required amount of magic (I forget what it's called, but there's a concept in some martial arts that making a sharp noise as you strike increases the strength of the blow. A similar concept could apply here). Yes, he could have, and in some ways he should have. But would it have had the same effect as everyone saying that he defeated almost every Sunshine soldier by himself? Harry has already shown that he'll do what he needs to to boost his legend.
4TheOtherDave10yThe term you are looking for is probably kiai.
7benelliott10yI'm not sure of the details of the spell she and Neville were using (I don't think it appears in cannon) but I had assumed that is protected both of them from everyone else for the duration, which would make sense if its purpose is to allow two aristocratic wizards to have their own private duel.
6Dufaer10ySeems more like just a further Star Wars reference to me. Well, even if she was somehow protected, note that she was not passively protected (not like a shield spell) - she still had to move to deflect and: So she probably did not have the agility to deflect another shot - especially in the middle of a block or similarly. Also: A reflected or friendly-fired Somnium could harm neither Harry nor Neville, so there was really little harm in trying - even if Harry came to your hypothesis, he still should have tried it – right after he made sure that she wouldn’t be cut in half subsequently. As for the other Sunshine soldiers blocking it - I confess that I do not remember how exactly the first-year Contego shields work and what their limitations are (I do not think this has been elaborated upon), but Daphne seems to be out of the main Sunshine cluster here (if there still is one), wielding a sword, as is Neville (so other would tend to distance themselves - they already have, before). She should be quite hard to protect. Of course, there might not be any Sunshine cluster anymore, if Sunshine rushed in-between the enemies, as they planned. But it rather seems to me that that plan failed before it was even initiated. (Their formation is not mentioned in the chapter.)
1bigjeff510yThey were directional, not particularly large but large enough for one or two people to stand behind, could not be fired through, and had to be maintained with the wand. The larger versions expand that up to a full sphere that can be fired through and only require concentration to maintain once cast. It seemed that each hit would drain the shield caster's magic, so your shield strength depended directly upon the strength of your magic.
2HonoreDB10yI think if he'd tried to Somnium Daphne, the other sunnies would have blocked it.
2Sheaman377310yAnd now we have it. Harry Somnium'd her, but waited until the others were distracted to do so.

I was a bit sad to see today that the last bit of Chapter 1 had been changed. I really enjoyed the original.

6Eliezer Yudkowsky10yPoint 1 - it wasn't stylistically consistent with later chapters. When I wrote the original Chapter 1 I didn't realize that this story was going to be funny. The part where Harry bites a math teacher in the original Chapter 2 is the exact part where I realized this story was going to be funny. Point 2 - I got tripped up by the differences between the published SF I knew and the expectations of fanfiction. If you saw a character talking like that in a published SF novel, you would know that he was an alien or genetically engineered or that the author meant you to know something was funny about him. In fanfiction they assume that it's either the author's conceit or, more probable yet, you're just a terrible author who can't write realistic eleven-year-olds. I thought it was so blatantly lampshaded that nobody could possibly mistake it for an accident, but no, fanfiction readers just don't think like that - they don't look for clues and they do assume lousy authors. So I made Harry's intellect slightly more subtle in the first chapter and let it dawn slightly more slowly.
5BenLowell10yI think that with the popularity of the fic, most people are making their way to it with recommendations that it is already good, so they will have a different reading strategy than somebody browsing for something worth reading.
-1komponisto10yI noticed quite a while ago with considerable disappointment that you had changed to (with annoyance at the inappropriate punctuation on top of it: if you must avoid a question mark here, use an ellipsis, not a period!) ...but until seeing Eneasz's comment [http://lesswrong.com/lw/3rb/harry_potter_and_the_methods_of_rationality/3maa] I totally failed to notice that you had deleted that whole paragraph! Shame! As a regular reader of neither SF nor fanfiction, I don't really care about the "expectations" of those genres. As far as I'm concerned, Methods of Rationality is its own genre, and that paragraph was very much stylistically consistent with the rest of the story, funny parts and all, and it was particularly consistent with Harry as we have come to know him. Actually, this part (minus the phrase "unmotivated conspiracies") sounds like something out of British children's fiction: Anyway, maybe the passage could be tweaked for lightheartedness if that's what you prefer, but I was really sorry to see the point about noticing confusion disappear.
4wedrifid10yBut, but... that was the defining introductory moment! It set the tone for the entire fanfic!
-1komponisto10yI'm not sure why this was a reply to my comment, beginning with "but", since it seems to be an expression of agreement.
0wedrifid10yConversational emphasized disbelief, not directed at yourself (as implied by the subsequent words).
0komponisto10yThat's what I first thought, but then I worried that I might have misunderstood.
6JoshuaZ10yI agree. I prefer the original form.
4Raemon10yMe as well.
0[anonymous]10yAnd me too.
1NancyLebovitz10yWhat was the change?

New:

There was a long silence in the backyard. Then a boy's voice said, calmly and quietly, "What."

Previous:

Harry just stood there, stunned. That was... unexpected... The skeptical part of himself noted that he still hadn’t seen anything that violated the known laws of the universe. Surely a little conspiracy was far, far less improbable than the universe really working like that. But it was also a technique of rationality to notice when you were confused. To stop and say: wait a minute, that feels a little off, my understanding of the world didn’t predict for that to happen. Even if Harry tried to explain the day’s events by sudden insanity or unmotivated conspiracies, that didn’t put everything back to normal. It didn’t make the day’s events expected. It didn’t make him feel not-confused. There was no denying that something very, very, very odd was going on. Harry looked up at the sky, and began laughing. He couldn’t seem to help himself. This is the most improbable day of my life.

6Risto_Saarelma10yThat looks like a really good change.

I can't help but think that Harry dropped an incredible idiot ball on deciding to go to Azkaban. I don't mean his deciding to trust his Professor and Mentor. I'm having trouble reconciling Harry's timeline with either his or (more importantly Quirrel's) decision making style.

8 AM - "Well, I have a big day of breaking into Azkaban today. So much to set up, I've got to be super careful!"

3 PM - "Hmm, it seems that the failsafe Quirrel setup in case anyone believes I was involved in Azkaban was triggered. Better go through with the plan anyw... (read more)

Harry got the note from himself at around 3:10pm. He left for lunch with Professor Quirrell in the late morning, went back in time, went to Azkaban, went back in time again to Mary's Room, and was grabbed by Dumbledore and rescued at around lunchtime. Those two time-loops did not intersect; they are separate time-loops.

5TobyBartels10ySo not only did they break into the most heavily guarded prison ever, not only did they break out the[*] most dangerous criminal known to be still alive, not only did they get away with it all to boot, but they did it BEFORE LUNCH! [*] (assuming that MoR!Voldemort already killed Grindelwald) (OK, I know, they had plenty of time in their own personal timelines to eat lunch. And they didn't finish until after lunchtime. But still.)
5Xachariah10yThank you, that clears up my confusion. I am afraid that I am too used to intelligent fictional characters having supernatural powers of planning and foresight. I suppose it is much easier to have readers be impressed with intelligence if smart characters are simply omniscient rather than acting rationally at all points. Therefore, if you were to be writing Quirrel with maximum intelligence, he simply MUST have planned it all at the earliest possible moment. It didn't occur to me that they could just be making the best of a bad situation, since that doesn't maximize the illusion of cleverness. He's a very smart human; he's not L/Light. I'll try not to be so hasty to make assumptions in the future and scan for any unspoken assumptions that are coloring my view when reading MoR. On further reflection, that's a good general life lesson too.
5Vladimir_Nesov10yHe doesn't know about Azkaban in the morning.
1major10yHarry was tested (via Veritaserum) after the Daily Prophet incident. The fact that he is being tested in regards to Quirrell's illegal activity is not evidence of it's failure, it only shows that it's impossible enough to make someone suspect Harry Potter was involved. A flashback where Quirrell explains the failsafe to Harry might have helped, though. For example, he would have foresaw the hide-from-dementors nature of Patronus 2.0 as a clue for Dumbledore (which is probably what prompted him to make this particular failsafe in the first place). How much of it did he explain to Harry? It is not really important, however. The moment Harry recieved the message at 3PM, he was committed. DO NOT MESS WITH TIME! Still, your question made me notice my (possible) confusion, so... good one.
0Xachariah10yThe alarming thing about being tested isn't that they tested Harry specifically; it is that they were aware that tests needed to be performed at all. Had the plan gone successfully, nobody would have ever have known that Bellatrix was removed. Remember that the entire advantage of Patronus 2.0 (to Quirrell) was the undetectable nature of it. It allowed a person to commit a perfect crime without the guards or dementors being aware that a crime ever occurred. From the point of view of Harry, sitting with his invisibility cloak in the empty room at 3:00 PM, only a small number of possible futures could exist: No note - Either the plan will go successfully, Harry shall be captured/killed in the attempt, or they abort for some other reason. Do not mess with time note - This also should result in aborting the mission since some terrible paradox occurred and you DO NOT mess with time. Passcode note - Harry will not be apprehended, but the plan will fail in some way and Harry is a suspect. Or Harry will chose to abort the mission and send back a false passcode preserve a stable time-loop. This is the result that actually occurred and is the only one that confirms a definite partial failure. I admit it is possible that, once the message was sent back in time, Harry and Quirrell were committed via fate to perform the prison break. The problem is that both Harry and Quirrell act as if No Note was received. In the TPSE chapters, we do not see characters who are aware that their plan will be detected. They do not seem to act as if their plan is definitely going to partially fail. Neither does Harry take heart in nor mention the fact that he has already survived escaping Azkaban. Contrast with the same situation in cannon!PrisonerofAzkaban where it is a major plot point. Edit: There is the possibility it is related to "Azkaban's future cannot interact with it's past", but then you run into the problem of Harry being able to send the note at all. If they abort or are just mo
0wedrifid10ySuch loops are stable even without any paradox. The extent to which one can deduce whether bad things happen depends on the psychology of the individual and existing priors. But so is this. A message 'Abort! X, Y and Z bad things will happen if you try!' can be reproduced and sent back in time perfectly well - and this kind of thing has been observed already in MoR.
2TobyBartels10yHave we had the version with X, Y and Z listed? (I agree that we have had Abort! messages reproduced and sent.)
0wedrifid10yNo, haven't. This seems to indicate a failure of rationality of the part of the time turner users. :)
-1TobyBartels10yThey may be trying to avoid sending more information than necessary into the past, since there are known limitations on that. (No information can be sent more than 6 hours in the past, even through a sequence of time-turners.) I can't think of a situation where it would be safe to send the information that something has gone wrong but not the information about how, and maybe they can't either, but they could just be playing it safe.
0cata10yOne obvious option is that Harry might have chosen to commit to sending a note back with opaque instructions to himself either way, even if no test were being performed. In that case, getting the note would mean only that he returned in one piece. Is there an advantage to that?
0Nominull10yI know Azkaban is warded against time travel, I don't know in what way that would play havoc with a time loop that passes through Azkaban.
0JoshuaZ10yIsn't that a Harry version that's gone back in time again a few hours? Edit: It actually might be nice if Eliezer could provide a diagram that has everyone's worldlines to help keep track of this. It isn't as bad as Primer but it is getting there.
2Vladimir_Nesov10yHarry didn't go back in time to 3 PM.

Indeed. Harry's personal timeline looks like this.

Wakes up, does morning stuff.

Goes to lunch with Professor Quirrell.

Azkaban!

Back in time to be picked up by the Professors at Mary's Room.

Receives coded note, delivers message to Professor Flitwick.

Reports to McGonagall's office, receives message to be passed to Flitwick.

Back in time one hour from 9 PM to send coded note through Slytherin mail to Margaret Bulstrode who will/did bring it the rest of the way back to 3 PM using her own time turner.

Visit to Dumbledore's office to hear his theory on Bellatrix's escape, and it turns out, to help Fawkes yell at him.

I was curious about the status of the review race, so I wrote a scraper to extract all HP fanfics of all ratings, with more than 40,000 words, and a bunch of data about each from ff.net. That is about 23,952 fanfics.

Here you can see the top 50 sorted by reviews, and if you know sql you can fiddle with the query whichever way you like. For those interested in the scraper itself, it's here (Click on edit to see the code. Please don't edit it unless you know what you're doing)

Reactions to Chapter 70:

Why, just a few centuries earlier -

What exactly is she talking about here? From the reactions, it appears to be rape (forcible rape of women by men), but unfortunately there's no reason to go back centuries for that. Even if Sinistra ignorantly assumes that votes for women put an end to rape, she still doesn't have to go back any farther in her history than she's already gone.

I think that's the most overtly evil Defense Professor we've ever had.

A good line made great by the follow-up.

7Mass_Driver10yOvert slavery. Prof. Sinestra also has dark skin.
3TobyBartels10yThanks. That fits the timeline, but I don't think that it fits the students' reaction: Of course, slavery ties in to rape (my reading of their reactions), but it doesn't make sense for Penelope to say "us" here. (Penelope has white skin.) There's also the sense of slavery in which men were (or are) owners of their wives and unmarried daughters, but that doesn't seem to be what you mean.
6TheOtherDave10yIf I see George being treated badly by Bill, I might conclude that Bill would treat me badly in the same circumstance, even if I know that George has green eyes and I have hazel eyes and Bill has some weird prejudice I don't entirely understand having to do with eye color. Someone raised in a culture that considers skin color of no more significance than eye color would presumably react similarly even if they know that George has brown skin and they have pink skin and Bill has a prejudice having to do with skin color.
1TobyBartels10yYes, but bringing in eye or skin colour distracts from the matter of sex, which is the focus of every other remark in the conversation. So it's an interesting hypothesis, and I don't have a better one, but it still leaves me confused. I'll provisionally accept it, but I still hope that somebody can think of a better one.
6TheOtherDave10yProfessor Sinistra was talking about the unequal role of women in Muggle society, and brought up her mother as an example. "And that wasn't the worst of it," she continues. "Why, just a few centuries earlier -" The writer cuts off at this point, but it seems entirely plausible that Sinestra went on to talk about how women like her mother were treated a few centuries earlier, and slavery is a pretty major component of that narrative. If they were discussing "the matter of sex," then I agree it's a distraction from the discussion. OTOH, if they were discussing how Muggle society treats its low-status members, with sex simply being an example of that, then it's a continuation of the discussion. This sort of situation arises all the time in real-world conversations, where what one person considers a reasonable continuation of the conversation strikes another person as a confusing change of subject. All I can say is, it seems like a reasonable continuation to me.
0TobyBartels10yI agree that discussing slavery would make perfect sense, given the conversation that preceded it. However, this ignores the conversation that followed it, whose participants seemed to be entirely unaware that they had been discussing any examples of discrimination other than on the basis of sex. Based on Quirrell's remarks in particular, I'm pretty sure that they'd been discussing rape, in one context or another. As I said in my last comment, I'll provisionally accept that they were discussing it in the context of slavery, since I can't think of any better fit. But it's still not a very good fit. Another point that I just thought of: Sinistra's "several centuries earlier" should have been simply "a century earlier", for this hypothesis to fit. Several centuries earlier than the early 20th century almost predates modern race-based slavery. (By the way, can we assume that Sinistra's ancestors were enslaved? Her ancestors may well have come from slave-holding British colonies, but are there any likely alternatives?)
[-][anonymous]10y 8

Chapter 69 was adorable. Thank you for that, EY, it was wonderful from beginning to end. Your Hermione is recognizably the same Hermione that I loved in canon, just reacting to a somewhat different set of circumstances: I think SPHEW is an excellent twist. And I'm starting to feel extremely fond of Daphne as well.

Very small question: I was confused by the line the Hufflepuff boy was sitting up, and groaning and rubbing his skull where he'd been dropped head-first into the floor; it was a good thing he hadn't been a Muggle, Hermione realized, or he might have snapped his neck.

What is it about wizards that makes their necks less likely to snap? Can somebody explain that reference for me?

9JoshuaZ10yThere are some implications in canon that wizards are more durable than Muggles, although canon isn't completely consistent on this matter. It may be simply due to the unconscious or reflexive use of magic. The two data points that are most relevant in canon off the top of my head are Hagrid's remark in book one that there's no way Lilly and James would have died in a car crash, and the fact that the upper limit on the lifespan of wizards is apparently much higher than that of Muggles (Dumbeldore is well over a hundred.)

Of course, it's possible that James and Lilly would never have died in a car crash because they have no need to drive.

2Raemon10yI thought it was more of a joke about the movies, where people get thrown around in typical hollywood fashion in ways that should kill a human but barely seem to phase the wizards. (Mostly during Quidditch)
7Sheaman377310yIn chapter 36, when Harry's family goes over to the Granger's for Christmas, I'm fairly certain there are other instances as well, but I can't seem to find any more. My vote is on reflexive use of magic, rather than a physiological difference.
1[anonymous]10yMy vote is on reflexive use of magic Okay, gotcha. I don't think that's supposed to be very reliable, though, at least not canonically.
8Sheaman377310yApplying Fridge Logic, I don't see how they could play a game where iron balls flew around trying to brain people without it being at least somewhat reliable. On the other hand, Dobby's Bludger did break Harry's arm...
0Eliezer Yudkowsky10yYep, see Ch. 17.
0[anonymous]10yApplying Fridge Logic, I don't see how they could play a game where iron balls flew around trying to brain people without it being at least somewhat reliable. On the other hand, Dobby's Bludger did break Harry's arm...
6Nornagest10yIt's not made particularly clear whether this is due to physical differences or unconscious use of magic, but there are a number of suggestions in canon that wizards tend to be physically tougher than Muggles. IIRC, Rowling's version of Neville was only discovered to be a wizard when he was dropped from a height and bounced.
3[anonymous]10yIIRC, Rowling's version of Neville was only discovered to be a wizard when he was dropped from a height and bounced. Ah, see, it never occurred to me to read that as anything other than subconscious use of magic.
2wedrifid10yThat is what Rowling implied. Eliezer seems to have satirised some of the unrealistic parts of canon with respect to human physiology under trauma by making wizards explicitly more durable in MoRverse.
2Normal_Anomaly10yAs some other commenters have pointed out, there's some fanon out there that says wizards are protected from damage by unconscious use of magic. I think it may have started with this essay from 2002 [http://www.hp-lexicon.org/essays/essay-that-had-to-hurt.html].

A question on transfiguration, timeless physics and what HJPEV could have known:

Harry's first year at Hogwarts is 1991. He transfigurates materials outside the confines of forms by thinking in terms of timeless quantum physics.

What was the state of timeless physics in 1991? Barbour's book was not published until 1999, for example, though presumably to have a book there was work leading up to it. What knowledge on the subject could Harry have had at that time, in a world without the Web as we know it, without even arXiv?

Edit: Barbour started publishing pape... (read more)

Let the man have some licence for pedagogy! The story wouldn't be worth much if it only taught lessons of things learned up to 1991.

Yup. Harry is allowed to know about cognitive psychology from arbitrary time periods, too, and have read anachronistic science books, etcetera. Science is Timeless.

5TobyBartels10yI don't think that this is a good idea. If Harry talks about, say, ice volcanoes on Titan, that will seem wrong to me. On the other hand, Harry doesn't seem to have said anything on physics that requires having read Barbour. Or have I missed it?
4ata10yChapter 28 [http://www.fanfiction.net/s/5782108/28/Harry_Potter_and_the_Methods_of_Rationality] :
8TobyBartels10yOther than the buzzword "timeless physics", this doesn't go beyond anything that I knew about in 1991 (when I was older than Harry but still in high school and had never heard of Julian Barbour). This is implicit in Minkowski's formulation of special relativity (1908) and Heisenberg's formulation of quantum mechanics (1925); I don't know who made it explicit, but I probably read about it in popular science books. ETA: The buzzword that I knew then (or perhaps learnt later and immediately connected to what I knew then, I'm no longer sure) is "block universe [http://en.wikipedia.org/wiki/Block_universe]".
0[anonymous]10yWhy doesn't Harry seem to have heard about the Singularity then?
7DanielVarga10ySlightly offtopic: Is Barbour becoming the "public face of timeless physics"? All right. But let's not believe it is because of scientific priority. The Wheeler–DeWitt equation is from 1967. Huw Price's book was published in 1996.
0David_Gerard10yCertainly the LessWrong face of it, per the QM sequence.
3JoshuaZ10yHarry's universe diverges somewhat from ours in a variety of respects. He'd have a lot of trouble knowing about carbon nanotubes also. It seems that accelerating some specific areas of science is within poetic licence.

Way way way way back in chapter 3, after McGonagall has told Harry about Voldemort's attack on him and his parents, it says:

(And somewhere in the back of his mind was a small, small note of confusion, a sense of something wrong about that story; and it should have been a part of Harry's art to notice that tiny note, but he was distracted. For it is a sad rule that whenever you are most in need of your art as a rationalist, that is when you are most likely to forget it.)

Is the "something wrong" simply that if the story is correct then there we... (read more)

8Sheaman377310yThere are loads of fan-theories as to how they would know specifically; my favorite is, based on how confidently Dumbledore explains exactly what happened that night, that he used Legilimency on the newly orphaned Harry. Another fairly prevalent one is that the scar Harry has is unique for being the result of a Killing Curse, yes, but curse scars in general are not unique at all. They also could have used any number of detection spells--honestly, there are a multitude of options. What I thought was wrong was that McGonagall explicitly said that the Killing Curse struck directly at the soul, severing it from the body. This is why victims of Avada Kedavra don't have a mark on them. But Voldemort's body was a "burnt hulk." Odd, that...
7gjm10yAt this point in the story Harry has never even heard of Avada Kedavra, never mind what someone who's been AKed would look like. [EDITED to add: The relevant question isn't whether there are in the Potterverse or the Methodsverse ways in which wizards might be able to know what happened that night despite there being no survivors other than the infant Harry, but what rational!Harry could reasonably have thought possible and plausible.]
4Sheaman377310ySaying that a spell severs the soul from the body comes along with the strong implication of not killing someone via bodily harm. He hasn't heard the incantation yet, that's true. But he just heard plenty about the Killing Curse. edit: I'm fairly confident that the concept of magic forensics is not beyond him at the moment. Besides, looking at it narratively, there has been way too long of a wait to find out what that meant for the payoff to be minor.
7[anonymous]10yCould the "something wrong" have to do with the concept of the soul?
7cwillu10yThat's my bet: Harry doesn't believe in souls, but he swallows the explanation without a second thought.
4gjm10yHe just heard plenty about the Killing Curse, yes. But that plenty doesn't include anything about what people who have been struck by it look like. I am not even slightly convinced that "it severs the soul from the body" carries a clear implication that it doesn't damage the body in the process. (Contrast "it removes the brain from the skull". If you heard that someone had had his brain removed, would you then be surprised if his head looked a mess?)
3Sheaman377310yNo. However, the brain is a physical object. The soul is not. This is a rather significant difference. edit: I'm not certain why I got downvoted. The brain is a solid object. If you remove it, it can be done in a way that leaves the rest of the head intact, especially when you factor in magic, but I wouldn't be surprised if it resulted in the head looking like a mess. The soul, on the other hand, does not have a physical component that we've found, so removing it would not necessarily result in any physical change (excepting the death of the target). Thus, the difference between the physical and the metaphysical object is relevant. Furthermore, by way of example, if the Killing Curse killed by turning their targets inside out (or immolating them) I would expect them to say that it kills by making their internal organs external (or burning them to death) rather than specifically and explicitly saying that it strikes the soul directly. Is this clearer?
4bigjeff510yI think the reason you were downvoted is the fact that a very large proportion of people on this blog (including Eliezer) believe that if their is a separate component we could refer to as a soul (or consciousness, or any similar concept), that it is entirely contained within the real world - that is, it is going to be some component of the brain instead of any sort of separate metaphysical property. I don't think it's fair to downvote you for that, since the opposite is clearly the prevailing opinion in the HP universe. However, given Eliezers extensive arguments against any sort of epiphenomena, I think it is highly probable that it was the mention of the soul that should have set off alarm bells for Harry, because SuperRational Harry shouldn't believe in a soul, at least not without major caveats. I think the soul question is going to come up in the eventual direct conflict with Voldemort, and that it is going to be a Very Big Deal. It is the source of Voldemort's immortality, after all. It's the most important question Harry needs to answer, and he hasn't even asked it yet.
0Danylo10yAh, but Harry doesn't believe in the concept of a "soul" as anything other than the result of a physical brain. Thus, his interpretation should be focused on damaging the brain.
1Sheaman377310yI think it more likely that Harry would think that it would still appear to kill without physical damage--the witches and wizards would take that as proof that the spell attacked the soul, and Harry would think that does something that we aren't sure of, but almost certainly it didn't actually attack a literal "soul." In my opinion.
2TobyBartels10yAnd that would be his error. I still hope to find that the kind of soul that Draco believes in --one that Muggles don't have-- will turn out to be something real (but of course not what Muggles mean by "soul", nor anything that Wizards really understand).
1ata10yYes, I recall that one of the books described the Killing Curse as leaving victims in apparently perfect physical health other than being dead.

Ch. 67: why does metal stop spells while cloth doesn't? It's not as if spells pierced clothes and made holes where they hit. If it's about tiny holes in fabric, something like permeability to water, would plastic bags work as well as metal? If it's about thickness, would styrofoam do? And if it's honestly about metal, how about aluminum foil?

In canon, the hardness and thickness of materials are described as stopping spells, especially stunning spells. Hagrid, e.g., is able to resist several Aurors' stunning spells for a few minutes because of his thick, hard, half-giant hide. No form of cloth or wool clothing is ever described as stopping a magical attack, but Harry can hide behind (presumably granite) gravestones for some time while Death Eaters blast away at them. Toilets, which presumably are not quite as thick or hard as gravestones, are shown as stopping one offensive spell but then exploding.

IMHO wearing metal armor is a brilliantly canonic tactic. The least plausible facet of it is that first years in January, average age 11.5, probably cannot build enough muscle mass to wear a full suit of medieval armor at all, let alone in two weeks. I do not think we have seen evidence that wizards are stronger than ordinary folk, as opposed to more resilient. The captains are described as wearing only metal shirts, but they practice by swinging metal objects on their hands and feet -- this is odd.

Actual medieval plate mail, of the kind intended to be worn in battle, weighed about as much as the safety equipment that hockey goalies wear today. There was a guy in a History Channel show that did cartwheels while wearing it. So Harry wearing plate mail probably would work, assuming he could get it to fit properly.

Chain mail, however, was indeed heavy and cumbersome, and "armor" designed for merely decorative or ceremonial purposes could indeed have been heavy enough to compromise the wearer's mobility, but Harry wouldn't have been wearing something like that.

0TobyBartels10yThen how come plate mail is listed with a higher encumbrance than chain mail in my D&D manual? ETA: :-)
6wedrifid10yPerhaps the same reason [http://en.wikipedia.org/wiki/List_of_common_misconceptions] that the D&D spells Melf's Minute Meteors and Meteor Swarm have much of their effect in the form of fire damage.
6CronoDAS10y1) Because the D&D designers either didn't know the truth or didn't care and 2) because it works better for game balance.
0magfrump10yIf you care about this kind of thing I recommend Riddle of Steel [http://en.wikipedia.org/wiki/The_Riddle_of_Steel].
0JoshuaZ10yD&D arms and armor has very little connection to history. Indeed, many historical fighting styles are either impossible or very difficult under the standard rules. (This is true in both 3/3.5 and 4th. I don't know how true it is in earlier editions.) Similarly, arrows are aren't nearly as deadly as they were historically. And then you have ridiculous things like the "dire flail" which seems to be a recipe for getting yourself hurt real fast.
0Randaly10y@ arrows: "I have seen soldiers with up to 21 arrows stuck in their bodies marching no less easily for that." ~Beha ed-Din Ibn Shedad (an advisor to Saladin) To be fair, the source I read the quote in ("50 Battles that Changed the World," page 34) implied that Beha meant that the arrows were mostly absorbed by their cheap quilted armor, not their actual bodies.

I've worn full-weight chain and plate reconstruction items while running around for a full day, and I'm not physically fit at all - I'd say that a random geeky 12 year old boy would be easily able to wear an armor suit, the main wizard-combat problems being getting winded very, very quickly if running (so they couldn't rush in the same way as Draco's troops did), and slightly slowed down arm movement, which might hinder combat spellcasting. It is not said how long the battles are - if they are less than an hour, then there shouldn't be any serious hindrances; if longer then the boys would probably want to sit down and rest occasionally or use some magic to lighten the load.

2drethelin10yThis. I've also worn multiple layers of armor, and something that's heavy to lift with your hands becomes much easier to handle when you're supporting it with your shoulders/body. If we extrapolate from harry, they transfigured the armor into existence, so it could be even lighter than average armor in any case.
0bigjeff510yThey wouldn't have had to get the heaviest stuff either, they were trying to stop first year sleep spells, not Auror stupify's. Chain mail was probably more than enough, and heavy wool might have had good effect if it were thick enough. Edit: I should have read down further, apparently chain mail is much heavier than plate. Who knew?
3gwern10yMy first thought when I finally figured out that the metal was about mundane armor and not something crazy like transfiguring muscles was 'why don't Aurors wear impressive clanking armor, then?'

As Harry said, this was a tactic that would only work against weak first-year spells; he did have to dodge Hermione's Stupefy.

7Sheaman377310yIt says early in the chapter, when Harry and Neville are alone, that this didn't count as giving Voldemort a good idea b/c the armor would only stop minor jinxes.
6gwern10yBut this is for the crappy armor that first years can both build in a short period and also wear. A full grown adult with governmental resources ought to be able to obtain and wear much better armor. Given the problem Aurors seem to have with surprise attacks, that alone might make them worthwhile! (In the real world, no one says bulletproof vests can stop only weaker bullets and don't do anything about explosions or knives, so there's no point in equipping soldiers or cops with such vests...)
6benelliott10yOn the other hand, its not a new idea. Harry mentions that some wizards used to wear armour in the dark ages, and they probably wouldn't have stopped using it if it was useful.
4gwern10yIn Eliezer's HPverse, that may be a sensible argument. (Given the general irrationality of wizard-dom, not a very strong one, though.) I'm criticizing Eliezer for diverging from canon, which IIRC has no suggestion that armor would be useful or had been tried but abandoned in the past. (The only example I can think of is maybe canon had goblin armor, and I'm not sure how that would apply.)

Canon already suggests spells can be stopped by solid objects, but only if they're sufficiently solid. And powerful spells have been shown to blast objects, while weak spells haven't. It's not much of a leap. In HP canon, historical wizards may or may not have worn armor of some sort, but for an adult wizard, armor is probably more trouble than it's worth. Considering how versatile a properly trained wizard can be in combat, it shouldn't be able to do more than force the opponents to slightly revise their tactics, while increasing the wearer's fatigue.

Remember that these are first years. The difference between the quality of armor they and the government can procure is much smaller than the difference between their combat ability and those of aurors or Death Eaters. If they didn't have such a demanding teacher, they would probably be incapable of anything resembling proper dueling at this point.

4Sheaman377310yIt could be that in order to get it to the strength that it will stand up to adult hexes, the armor becomes too cumbersome to actually use. This is true, but in the real world, cops face bullets somewhere around as often as knives (I believe; does anyone know differently?) and far more often than explosions--Dark Wizards, on the other hand, don't go around offensively using first-year spells...basically ever.
0gwern10yIsn't that a rather convenient outcome, though? Why should we think that? Hence the point that we would expect adults with government resources to be able to wear both heavier armor and much better armor for a net protective effect far beyond what Harry et al managed.
9Desrtopa10yBecause if that weren't the case, we might expect aurors to wear armor, and they don't. A hypothesis that suggests that armor isn't useful for adult wizards predicts our observations better than one that suggests that it is.
0gwern10yOne man's modus ponens is another man's modus tollens; we can use the observed lack in canon to argue for Eliezer conflicting with canon or we can use it to argue canon invisibly agrees with Eliezer.

General rule of fiction. If there are two possibilities, neither of which is confirmed or denied in text, assume the one that makes sense.

0gwern10yOK. So to use an earlier Yudkowsky example, what possibility about arbitrage should we assume holds true in canon? That there's some clever witchery which makes it impossible or that Rowling simply made a mistake and didn't think about the economics? If we assume perfection on the part of the author, doesn't that lead to an odd and desperate kind of rabbinical midrash?
4TobyBartels10yI assume both: Rowling never thought of it, but if it were brought to her attention (and she considered it worth bothering about), she would probably declare that the Goblins had some clever witchery (or goblinery) that makes it impossible. So I proactively make that assumption for her, while still doubting that she ever thought of it.
1JoshuaZ10yMore plausible explanation if you need a fanboy defense: Nothing in the text ever says the coins are pure gold and silver. They could work just like Muggle money and when people refer to them as silver and gold it isn't any more meaningful than calling US pennies copper. The fact that coins are stored in large vaults and apparently aren't earning interest does indicate that there are aspects of the system that don't work as the modern muggle system does, but there's not a strong argument that the coins are pure metal.
0TobyBartels10yBoth possibilities (protective spells, not real gold) are suggested at the Wikia [http://harrypotter.wikia.com/wiki/Wizarding_currency].
2benelliott10yOne could assume that wizards never thought of it. I'll grant that sometimes author's do just not think of things. However, if there is a perfectly good explanation then I see no reason to throw away my enjoyment of the story by ignoring it.
3gwern10yAh, but I don't come to the MoR discussion threads just to enjoy it. That's what reading it is for. I come to the MoR discussion threads to nitpick and tear it apart!
1buural10yMy thought is that wizards are not confined to projectile weapons. Armor would be next to useless if the offensive magic, for example, is fire based or involves water or gravity manipulation. Moreover, an armored helmet significantly constrains both visibility and mobility, which may make the wearer more vulnerable.
1Thausler10yIt probably wouldn't be too hard to create a magical patch for the problem of not being able to carry armor. Wingardium Leviosa is a simple patch to lighten the load, and even if it has limited duration it would be an excellent spell to cast immediately before going into combat.
3Sheaman377310yDoesn't Wingardium Leviosa have to be maintained? I don't think it's a fire-and-forget spell.
2Desrtopa10yEven if the armor isn't weighing down on you though, it still has inertia, so you have to exert yourself to move the extra mass. Maintaining a wingardium leviosa on it might be more trouble than it's worth.
5Eneasz10yMagic'ed stuff may not have inertia. Remember the description of broomstick flight during the escape from Azkaban? Harry was surprised to have to deal with concepts like "inertia" again when using a rocket, as the broomsticks do away with such inconveniences.

Maybe its the same reason that broomsticks use Aristotelian physics. If magic was intelligently designed by people who didn't know much science you would expect it to obey the law of "it makes sense so long as you don't think too hard".

7cousin_it10yAnother idea along these lines is that combat spells work like "counterfactual weapons" - they get through iff a blade would have worked instead. But in any case Harry should have investigated that before trying to level up Str. As per the current version, he probably did check that metal would stop spells (otherwise the whole plan would be mere stupidity); it's not such a big leap to try styrofoam while you're at it.

it's not such a big leap to try styrofoam while you're at it.

Muggle artifact prohibition?

6DanielLC10yHe said it was only allowed because people wore it as regular clothing. Unless he could find records of wizards wearing styrofoam, that won't work.
[-][anonymous]10y 12

This is a good question for gaining insight into the way spells work, and it seems like an easy one to investigate - one just needs to shoot several spells at another person through a bunch of shields made of different materials and of varying thicknesses, then check if any patterns emerge. If Harry's not too busy, he should look into it.

7NihilCredo10yI suspect plastic and refined aluminium are Muggle-only technologies.

I have hesitated before posting this, "is it appropriate", "is it relevant", I wondered. But this siteis deeply concerned with morality, and the application of rationality threin. Hence, I submit the following, knowing that I am not alone in the predicament I describe, and that people who are in my current state are among the greatest obstacles we have to overcome in our way to saving humanity from the UFAI. Here is my report:

I have been rereading this fic aas of late. I am dismayed to find out that the distance between me and Rational!... (read more)

1Raemon10yThe things that inspire people vary wildly. We (I) can't answer this without knowing more about you (possibly more than would make sense to share in a public space). Are there particular things that have made you feel like humans are hopeless? There's a narrow subset of people who are inspired by the all-encompassing vision of a utopian future that Harry desires. I think most people are inspired by more specific things - addressing issues of racism that they have particular exposure, addressing specific issues of government corruption that they care about, etc. Are there things you care about that are more specific than "fix the entire world?"
2Raw_Power10yEh, how can I put this... I used to think I could make huge improvements in that sense through the invention, perfection, production, and distribution of useful machines. Hence why I decided to become an engineer rather than an MD as my parents intended: I thought I might help more people the first way rather than the second. But then I find out about the FAI, the ultimate machine, which, in sixty years or so (the time I thought it would take me to cause any actual change), would make all my efforts as a drop into into the ocean... And I'm cmpletely useless at math higher than Calcuculs II, and hate coding, so I'm also irrelevant in making the AI, so I feel like whatever I'd be doing until the Singularity would be... passing the time, basically. Plus I thoght I'd eventually need politics, social manipulation, etc. if I wanted to neutralize those on whoe toes I would inevitably step. But the more I learn bout that stuff, the less I feel like people are worth the sacrifice, and ALSO the less worthy and capable I see myself of those tastks, since my ideals hav been tested against real-life situations, and I have failed to reach my own standards, time and again. I mean, I know I have a very strong Neutral Good inclination, but in practice that usually translates into "fuzzy-maximizing" rather than "utility-maximizing". I need to feel I'm useful right now, immediate gratification, otherwise... are any of you familiar with the Rage Comic meaning of "Yao Ming"? Yeah, that tends to be my reaction to stuff s simple to "rise in the morning, take a shower, go to class, take notes, work at home, do it again tomorrow". Oh, and the "you're putting too muc wieght on your shoulders" argument does not work for me: if you tell me I'm getting ahead of myslef and nobody needs me and nothing really matters I'll just go in a basement and dedicate the rest of my life to jerking off or something. The reason I'm sharing all this here is that, from what I can tell, these traits aren't
3Eneasz10yWe're a HIGHLY specialized society. For several dozen people with just the right skills, capabilities, and motivations to get together and dedicate their efforts to creating FAI requires a support society that numbers in the hundreds of thousands. People to sell them goods, people to build their houses, people to patrol their streets, people to keep their governments running. People to transport their goods to the store, people to have built them in the first place, people to grow their food. People to mine the ore and smelt it into steel and shape it into tractors and harvesters to grow that food in the first place. People working at all levels of all the corporations in between, making sure things keep flowing smoothly - accountants, clerks, managers, salesmen, janitors. And all those people are also supporting each other at the same time. And in between being productive, people need to rest and recharge, which requires entertainers, and maybe inventors to create new devices which make life easier so they can spend less time washing their dishes and more time being productive or enjoying their time. You are contributing directly even if you are only a cog in this vast machine. It is a wondrous machine of humanity that makes the creation of FAI possible, and just because you are not in the group putting the lines of code together doesn't mean you are unimportant to the final product.
3Raw_Power10yThanks ;_; Then this means I should dedicate all of my efforts to be the best engineer I can. I may only play the role of a speechless extra, but like Brad (Glee's Pianist), I'll still give it my all! (Also, my life has gotten ''much'' better as of late, and new opportunities for advancement both academic and social have opened up... Germany, here I come!)
2hairyfigment10yDon't know if this has helped me yet, but I'll ask anyway: what would you want to do a few subjective years or centuries after the Singularity? [http://lesswrong.com/lw/wv/prolegomena_to_a_theory_of_fun/] If you find an answer then by your assumptions you have something to live for. This at least gives working for survival some added value.
1[anonymous]10yIf you only care about reclaiming a superficial feeling of humanism, I find listening to Carl Sagan's old recordings helps. But somehow I feel that's not what you're looking for. To be perfectly honest, I feel like this most of the time, too. Humans are bastards, but only because the bounds on their rationality tend to be rather tight. Humans are idiots, more or less. But I think the crux of the problem is whether or not humans are really hopeless. We have some evidence, in the litany of heroic spirits, that every once in a while some humans can rise above being bastards and idiots. In my own view, the short-term purpose of humanism is to make that happen more frequently. Who better to start with than oneself...

We're told that Azkaban cannot interact with its past. I take this to mean that there are no loops of causality within Azkaban, where time A affects time B, which in turn affects time A. More generally, no information from a later time in Azkaban can be sent to an earlier time in Azkaban (since the converse seems always possible). Similarly, it's implied that, even through a chain of time turners, no information can be sent more than six hours backwards in time anywhere.

By the understanding of modern physics, these cannot be hard-and-fast rules. A slig... (read more)

4JoshuaZ10yYes, this point has been made before. In general, magic seems in many ways to operate on a human scale according to human intuitions. See e.g. my remarks here [http://lesswrong.com/lw/30g/harry_potter_and_the_methods_of_rationality/3084] and the subsequent discussion.

I wonder if Quirrelmort has been every DADA teacher since the supposed "curse". If V. was the one who supposedly cast it, it would have been simple enough to remove it, make an exception for himself, or simply not cast it in the first place. He is known to be many people, and to desire the position. Why not make maximum use of it? The constantly changing identities would both enable him to give a highly inconsistent quality of education from year to year without raising eyebrows, and would make his activities harder to track in general.

3Desrtopa10yWhy would he want to give a highly inconsistent quality of education from year to year? Whatever Quirrelmort's goals, I personally doubt he would accomplish them by way of a plan that involved a four-way with a group of fifth years in a closet.
0Pavitra10yNot terminally, but instrumentally. There's no obvious reason to constrain himself to give a highly consistent quality of education, so why not make himself some room to move around? It's not like two consecutive unrelated teachers must provide totally different qualities of education. He probably wouldn't actually do that, but he might Memory Charm them into thinking he had, or Crucio or Imperius them into saying he had.

One theory I've had for a while:

Maybe the death needed to make a horocrux is not needed to preserve the mind. it is needed for the minds ability to cast independent magic. One could make a perfectly fine horocrux without killing anyone that had the only problem that you'd be a muggle when you were brought back.

This is the most important consequence of a more general theory: What a wizard means with the word "soul" is their independent magic power source, and that follows some conservation law. Evbidence for this includes wizards not considering m... (read more)

2Pavitra10yThis would make Draco's statement that muggles don't have souls accurate. Combined with McGonagall's statement that AK strikes directly at the soul, it would seem to imply that (1) AK should have no effect on muggles, and (2) AK should be nonlethal, only rendering the wizard nonmagical.
4TobyBartels10yCanonically, AK causes destructive side effects (inanimate objects' blowing up when hit, etc). It could be that it strikes at the soul, severing a Wizard from their magical power, and additionally causes a blast that would kill an ordinary Muggle (but not a Wizard that remained a Wizard). So it kills Wizards by a two-step process, and Muggles by one. However, modern Muggle technology might be able to defend against it, unbeknownst to the Wizards. I think that this makes AK a little more complicated than it should be. But the canonical AK (and especially the AK as seen in the movies) already is more complicated than it should be.
2Normal_Anomaly10yI don't think it would be a "blast" in the sense of blowing up a desk, since people hit by it are left (according to canon) "in seemingly perfect health, except for being dead."
0TobyBartels10yThat's true; the problem is that this is not how it's shown in the movies, nor is it consistent with the side effects in the books. Further research is needed.
2Armok_GoB10yMcGonagall might simply be WRONG about it striking directly at the soul.
0Pavitra10yOf course. And likewise, wizards in general could be completely rather than partially wrong about the nature of souls.
2Armok_GoB10yum, I think you misunderstood my theory: what wizards mean with the sequence of symbols "soul" is not "that which makes you, you" but "magical power source that can't be copied". It's not about if they're right or wrong, it's about what concept the symbol references. Their beliefs ABOUT souls, such that people without souls are of less moral worth, can and is still often wrong.
1Pavitra10yThat's what I thought you meant. Perhaps you misunderstood mine: that the concepts wizards associate with the sequence of symbols "soul" does not even slightly resemble anything in reality.
-1Armok_GoB10yWell, it's possible but it doesn't seem very likely. The only requirement of reality for that concept to make sense is that magic requires somehting that is in some way scarce, for example such that wizards have it but muggles or spell effects don't. If this comes in discrete chunks or not, if if's made of information or some more tangible magic substance, if it can be duplicated with sufficient effort, etc. do not place strict requirements.
2DavidAgain10yIf McGonogall is right, then agreed on (1). But not (2): if wizards have integrated a magic source into themselves sufficiently to use it, presumably destroying it could have knock-on effects. If I strap a jetpack to myself, something which strikes directly at the jetpack could still lead to me being left in small, burning fragments when it exploded.
0Pavitra10yThat's a good point. And even if the magic doesn't explode, the body might have grown dependent on the magic; we know that wizards don't break easily, and it seems reasonable that there might be other health benefits as well.
1DavidAgain10yIndeed, especially the really old ones who presumably haven't bothered to use anything else to sustain their bodies. Rather like vampires descending into dust as the supernatural forces holding them together disappear and the entropy catches up with them. Which is why newly-created 25 year old vampires becoming grave dust in Buffy always distressed me.

Ch 69

she'd never been able to detect the magic involved

That's because, thanks to Dumbledore's knowledge of Muggles, there is no magic involved.

4Sheaman377310yThere's no magic involved in making a tin appear out of nowhere? So, sleight of hand?
2TobyBartels10yThat's my guess. ETA: McGonagall could probably detect this easily, once she actually knows what to look for.

Upvote this if you think MoR has been getting worse lately.

Two Questions/Guesses

1) Prof. Quirrell pointed out that Harry was especially vulnerable to the "Finite Incantatem" spell (to removed his transfigured armor). How does the canon mechanics of this spell work from a tactical standpoint? Is it area of effect or targeted on a per spell basis? Can a weak 1st year dispel a casting done by Headmaster Dumbledor or does caster strength play a role in its effectivity? Depending on the answers, Harry's vulnerability could be mitigated by pure strength or recursive spell depth or minor covering spells to... (read more)

7taryneast10yHe already tried on "computer simulation" - but discarded it when he found out how the time-turner worked. I'm personally wondering when Harry figures out that he's actually a fictional character :)
4[anonymous]10yWhile it might be a bit too mind-screwy for MoR, I can't help but to think that it would be amazing if, say, Harry confronted Eliezer on allowing Azkaban to exist within his universe just so that the latter could have an interesting and important location to use in his story. Something like Non-Player Character [http://www.transhumanism.org/index.php/th/more/341/]. Omake opportunity, perhaps?
5Broggly10yThe obvious response is to include in the trigger warning a statement for any sufficiently advanced intelligence or humans with philosophical reservations about imagining other conscious beings that the story includes suffering, descriptions of suffering, and people reflecting on the suffering of others in detail.
0taryneast10yAwesome idea. :)
2TobyBartels10yAnd discarded it without good reason [http://lesswrong.com/lw/3rb/harry_potter_and_the_methods_of_rationality/3evv].
0major10yI think Ch21 (near the end) played with this idea already. How many potential first week has Eliezer thought through before settling on that one, I wonder.
6Sheaman377310yAs I understand it, Finite Incantatem is an Area Effect spell, while Finite is targeted. Additionally, strength definitely factors in--again, as I understand it. edit: Strength has to factor in somehow. Even ignoring the ridiculous unbalancing effect that would have, they're in Hogwarts. If it would cancel every spell in the area, regardless of strength, Hogwarts itself would be affected with every cast.
8Eliezer Yudkowsky10yHaven't really thought about it until now, but I'll assume that Finite is a brute-force method requiring strength proportional to the original spell to cancel (so a Transfiguration that takes minutes would require a mass casting to cancel, perhaps) and sometimes won't work at all, while specialized counter-jinx just works if the caster has sufficient strength to cast it.
3Psy-Kosh10yDepends... if the original spell took time/effort due to it being, well, for lack of a better word "delicate", then finite should work easily on it, while a simple spell that you can just pump more and more power into should require a really strong finite to cancel. At least, that's how I'd imagine it.
4Normal_Anomaly10yHe's considered the simulation argument before, in chapter 14 when he gets the time turner. As for magic being "glitches," I'm not a programmer, but the magic seems too consistent not to be a part of the intended program.

Glitches seem like a bad analogy, but cheat codes seem like potentially a pretty good one. Perhaps the developer console of the universe speaks bad Latin.

5Normal_Anomaly10yCould be. Especially since the truth of the matter is that Harry is in a simulation, a story in our world. Whether he finds out is another matter. I doubt it from a literary perspective.

And, indeed, a story in which past events are occasionally edited.

2Normal_Anomaly10yHeh. Yes. Harry has thought about sending a signal to himself and can see through the illusions of dementors. What would happen if he found out about the edits? I doubt it's going to happen, but it would be awesome.

The kind of simulation that Harry is in (that is, a piece of fiction) is admittedly not one where the initial conditions are established and it is calculated forward from there, such that X2 rather than X1 happening at time T1 necessitates Y2 rather than Y1 happening at time T2.

So, agreed, editing the chapter that describes T1 from X1->X2 doesn't necessarily cause evidence (e.g., Harry's memories) of X1 at T2 to change, so in principle he could notice the difference.

Which would in and of itself be a useful piece of information about the nature of the universe, I guess. He'd know that his perceived present is not in fact contingent on his past, but is instead separately created by some sort of external creator, who for whatever reason creates the illusion of such contingency.

As a literary choice, I disagree about its awesomeness... this kind of narrative self-reference is good for a kick-in-the-head, but it's difficult to maintain any kind of worthwhile narrative thereafter.

Then again, EY has already devoted many many words to the idea that a set of values can be both arbitrary and worthwhile, so perhaps he'd relish the challenge of writing a compelling Harry aware of his own... (read more)

2Normal_Anomaly10yThat's true, and part of why I doubt it will happen. I meant that the idea is awesome and the reactions of the characters would be fun to read, not that it would actually make the book better.
0NihilCredo10yMetafiction [https://secure.wikimedia.org/wikipedia/en/wiki/Metafiction].
0DanielVarga10yThe fact that the author did not mention the obviously relevant simulation hypothesis in 68 chapters (am I correct?) also suggests that he might have bigger plans with it.

The fact that the author did not mention the obviously relevant simulation hypothesis in 68 chapters (am I correct?)

Mentioned in passing in chapter 14:

You know right up until this moment I had this awful suppressed thought somewhere in the back of my mind that the only remaining answer was that my whole universe was a computer simulation like in the book Simulacron 3 but now even that is ruled out because this little toy ISN'T TURING COMPUTABLE!

Best wishes, the Less Wrong Reference Desk.

5DanielVarga10yThanks! All right, that rules it out. It is a bit weird, because I think the quote ends with a non sequitur. If we live in a Turing-noncomputable universe, we can build a computing device (hypercomputer) that can run the simulation of another Turing-noncomputable universe. (*) So the non-Turingness of a Universe is orthogonal to its simulatedness. (*) Not always, but this is irrelevant here.
7TobyBartels10yMore directly, making something close enough to a time-turner to fool the residents is certainly Turing-computable. ETA: Especially if you're in charge of computing the residents!

The Atlantic put up a piece today using HP:MoR as the take-off point for discussing fanfiction and fan communities.

0TobyBartels10yThat was nicer than Time magazine's recent piece fanfic, which focussed on the example of Harry Potter (often stuff) on FanFiction.net) but never mentioned the most reviewed example.

I remember the author's comments some time ago to the effect that he was surprised that many readers (myself included) weren't immediately sure that Quirrell is Voldemort. Has anyone considered that this might be a trans-forth-wall version of Bystander Effect?

The (presumably omniscient) narrator isn't pointing out that Quirrell is Voldemort. The (presumably well informed) Professor Dumbledore has disclosed no such suspicions to the reader. (Presumably cunning and logical) Rationalist!Harry hasn't made any connections between the sense of doom, harmonic ... (read more)

2TobyBartels10yThe narrator isn't omniscient; he only tells us things from certain characters' points of view. I agree that it is suspcious that neither Dumbledore nor Harry think of this. But in fact neither has any reason to suspect that Voldemort is still alive, while we (having read the original series) do. (Also, Dumbledore was really bad about this sort of thing in canon.)

I am having trouble scanning the HPMoR thread for topics I'm interested in due to both it's length and the lack of a hierarchical organization by topic. I would appreciate any help with this problem since I do not want to make comments that are simple duplicates of previous comments I failed to notice. With that in mind, is there a discussion forum or some method to scan the HPMoR discussion thread that doesn't involve a lot of effort? I have not found organizing comments by points to be useful in this respect.

Edit: I'm new and this is my 1st comment. I've read a lot of the sequences, but I don't know my way around yet. It's quite possible I'm missing a lot about how things work here.

2Unnamed10yYou're right, the MOR discussion threads aren't very well organized for that. They work well enough for having an ongoing discussion, but not so well as an archive of the discussion that's already happened. If you have a particular subject in mind and you want to see what's been posted about it, the simplest thing is probably to search the thread(s) for relevant keywords, including the chapter number. You could either use ctrl+f on each one of the threads that might contain relevant discussion, or the site's search function. Don't worry so much about duplicating previous comments. It's worth doing a quick search to try to avoid it, but when it happens it's not so bad (especially with threads like these ones). If you don't have a particular subject in mind and you just want to skim the discussion to see what's interesting, I don't have anything better to suggest than sorting by karma points.

I like this line:

"I do not give you, but loan you, my cloak, unto Hermione Jean Granger. Protect her well."

At first you think that he's talking to Hermione!

All the way back in chapter 1, Petunia says:

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.

The main (although not the only difference) between canon and HPMR is Lily and Petunia's interaction in this context. In canon, centaurs are creatures which see the future. This makes me very worried that a centaur foresaw that if Lily helped Petunia bad things would result. Since this is the main departure from canon, is this a reason to think that the story is going to have a really downer ending?

5Xachariah10yTo comply with the prophesy, her actions need only result in a bad ending for centaurs.
3Sheaman377310yPerhaps. Or perhaps it meant that the Second War would be much worse this way, though they still are victorious. Or perhaps even just that the possibilities were worse, not necessarily that it could only end in failure.
0HonoreDB10yThe end of the world is not necessarily a downer ending.
2[anonymous]10yThe only ways I can imagine the end of the world not being a downer ending are: 1) There was an even worse alternative in the cards (since this is LessWrong, let's say it was 3^^^3 years of agonizing torture for the whole human race) and we managed to dodge it by dying. But the fact that we were even faced with such a choice sounds pretty down-ish already. 2) You're some kind of negative utilitarian. Or perhaps a Buddhist. 3) From a certain point of view [http://wiki.lesswrong.com/wiki/Not_technically_a_lie], you could describe the emergence of a new utopia as "the destruction of the old world" or something like that. That's how they got away with it [http://www.youtube.com/watch?v=7qQobeKCAhg&t=3m45s] in Alexander Senki. Or else "the end of the world" refers to something that would have happened anyways, like the end of Sol or the heat death of the universe. Thus, it will happen if Lily is nice to Petunia - it just neglects to mention that it would also happen if she wasn't nice to her sister, too, thus letting the listener believe there is a causal connection where none exists.
0hairyfigment10yPromethea used a version of #3, saying the end meant the end of our ideas about the world. Thinking about this, it occurs to me that perhaps the centaurs saw history along this path proceeding up to a certain point in time and then (it seemed to them) stopping. They might have explicitly told Lily that they couldn't perceive anything after the Event Horizon, and the subtlety got lost along the way to the second repetition.
0Desrtopa10yI figured he was talking about an "end of the world" as in The Sword of Good [http://lesswrong.com/lw/169/the_sword_of_good/].

I have a couple of theories about how Fred & George managed the Rita Skeeter prank. We know from Quirrel's response that Rita Skeeter's article included evidence from a variety of sources, difficult to fake, and certainly costing more than 40 galleons. The obvious implication is that either they got some covert support (Professor Quirrell/Tom Riddle?), or they found a simpler method. I can think of two.

  1. Modify Rita Skeeter's memories. Make her remember viewing all the evidence, when in fact she hadn't seen them. Hiring someone to do that probably woul

What Hermione really needs is Something to Protect- her own autonomy isn't big enough.

0rdb10yPerhaps SPHEW will help there. Harry has had knowledge of the nature of the "magical remnant of the Dark Ages" since meeting Draco at the station, reinforced by Azkaban,. Hermione would know intellectually (quoting Harry) "So the world is broken and flawed and insane and cruel and bloody and dark. This is news? You always knew that, anyway...", but should lack direct experience, that her fellow students may have. Will Draco conspire to protect Hermione against the Slytherin bullies?

May I just say that this quote from ch. 65 sums up the Fountain of Irrationality beautifully and succinctly:

No. Just an example. Lies propagate, that's what I'm saying. You've got to tell more lies to cover them up, lie about every fact that's connected to the first lie. And if you kept on lying, and you kept on trying to cover it up, sooner or later you'd even have to start lying about the general laws of thought. Like, someone is selling you some kind of alternative medicine that doesn't work, and any double-blind experimental study will confirm that i

Has EY written something like the above elsewhere as succinctly, or did he first sum it up here?

Harry's monologue summarizes ideas discussed in "Entangled Truths, Contagious Lies" and "Dark Side Epistemology". Best wishes, the Less Wrong Reference Desk.

"...it's not like I'm an imperfect copy of someone else"

Irony alert! Or at least one more piece of evidence in favour of the Harry = Voldemort Copy theory.

In fact this is a fabulous fic, but it's kinda like you grabbed a terry pratchet novel stuck it in a blender with a Steven Hawkins essay and a book on the theory of string theory, turned the blender on and then spiked the mixture with LSD. In a good way, i think.

Is it bad form to down-vote a poll just because you think it's a bad poll? If you have a criticism to make, then make it. That's what this thread is here for. Or if you have great praise to lavish upon HPMoR, do that instead. That's also what this thread is here for. But to put up a passive-aggressive and vague poll like this is annoying and gives no good info of any sort to anyone. It feels like a bludgeon being set up for future use.

Say what you want to say.

1TobyBartels10yEspecially since you've explained your criticism of the poll, I think that you ought to be able to downvote the poll itself, as for any other comment. (Or upvote it too, of course.) This is separate from any votes that actually take part in the poll.

Listening to the Hitchhiker's Guide today, I noticed another reference in Chapter 13 that the TVTropes page seems to have missed:

Zaphod (after Trillian mentions picking up the hitchhikers): "Okay, so ten out of ten for style, but minus several million for good thinking, yeah?"

Ch 68

she was trying to count the number of things in the room for the third time and still not getting the same answer, even though her memory insisted that nothing had been added or removed

That's because the things got added or removed when her attention was not on them, even while they remained in her field of vision, so that she thought that she would have noticed even though she didn't.

There's a name for this, but I can't remember it. Muggle researchers do it on monitors with a camera that tracks your eye movements, I think.

2Nornagest10yAttentional blink? [http://en.wikipedia.org/wiki/Attentional_blink]
3TobyBartels10yNo, that doesn't seem to be it. Although an online test seems to suggest that I don't suffer from this, so that's nice to know. What I'm thinking of has several apparently static figures on a screen, and as you look around the picture, things change when you're not looking at them (even though you think that you're looking at them, because the entire screen is in your field of vision the entire time). I think that mostly they change colour and stuff, but sometimes they disappear entirely. You can't just do this online, since there also has to be something to track your focus of attention, so I've only read about it.
5Sniffnoy10yI believe this is just known as change blindness [http://en.wikipedia.org/wiki/Change_blindness]. Edit: Hm, no, looks like you're describing something more specific. I still think it falls under change blindness, though...
1TobyBartels10yYes, this seems reasonable, although I don't recognise the term. ETA: Following Wikipedia's links, the stuff here [http://www.ted.com/index.php/talks/dan_dennett_on_our_consciousness.html] from 8:30 to 10:00 seems most like what I'm thinking of, although still not quite as dramatic as what I remember. By this point, it's possible that my memory is just faulty.
2DaveX10yI think I saw a demo, or video a demo, about 15 years ago, of the ERICA gaze-tracking program at UVA where onlookers could see the screen change characters while the person whose gaze was being tracked couldn't see the changes. If I remember correctly, it was a screen of normal text in MS-Word or something that would mutate into gibberish where the user wasn't watching.
0TobyBartels10yOK, then somebody else remembers it! (I don't remember that it was text, but this is close enough.)
0Sniffnoy10yOh, OK, I misunderstood what you were saying. That's not change blindness, then, that's just not being able to see things you're not looking at...
3TobyBartels10yBut which you think that you're looking at, so that at the end you're surprised by the change. The change-blindness stuff in Dennett's video that I cited 4 posts up had the same result, although a different method. (Whether that similarity is enough to make DaveX's stuff also count as "change blindness", I have no opinion.)
1[anonymous]10yA fun thing happend to me. I did the test at http://mindbluff.com/movblink.htm [http://mindbluff.com/movblink.htm] and I noticed the C but only subconciously, that is I knew that I had seen the C, but I didn't remember actually seing it.
0bogdanb10yI consciously saw an R, and I consciously saw a C later in the sequence, but I couldn’t tell if they were actually consecutive, nor if there were other R’s and C’s around them. (I didn’t look at the video in slow motion to check.) Just in case someone’s counting :)
0TobyBartels10yThe first time, I noticed the ‘C’ only. The second time, I consciously noticed them both. (ETA: This isn't the test that I took before.) To what extent might your feeling that ‘I knew that I had seen the C’ be influenced by their having earlier told you that you would? (For that matter, what are the odds that what I ‘consciously noticed’ was an illusion?) An interesting test might be one where there is no ‘C’, asking people whether they saw it.
0[anonymous]10yWithout the test it's impossible to know. I find it quite plausible that some part of my brain noticed the attention blink because it was primed to it and "filled in" the C.

Chapter 72:

Did whatever Snape was planning for Rianne to do already happen?

There is his weird clap in the great hall, and his smile after chiding Jaime Astorga. Apparently he warned Jaime and others that morning, perhaps he anticipated them reacting in this particular way and be beaten by the girls? Why? And it seems the fight was fairly close run, so he shouldn't have been able to predict the result unless he just got lucky (or relied on future information). Perhaps he planned for either outcome, but what is he even trying to accomplish?

And how does Ria... (read more)

7Danylo10yWell, Snape himself was bullied, and earlier in the story he asked HP to stop a bully, so I'm guessing he orchestrated the fight to raise the reputation of SPEW and marginalize the bullies. It was mentioned that a first year wouldn't be able to break the protego spell, so perhaps he helped out? This would, of course, mean that he delivered the letters and/or orchestrated the "prophecy" as well. As a side note - it's been so long since the last update that it took me maybe 1/4th of the chapter to fully understand what's going on. Perhaps I should have skimmed 71 before reading. Final side note - Eliezer, what do you think of ASOIAF? FFSN - On the whole 'forgetting the story' theme - who was Rianne?
2hairyfigment10yRianne appeared in the previous chapter when Snape offered her fifty Galleons for something that, much to her dismay, was probably not sex. As for Snape's goal, maybe the Head of Slytherin House has his own, in-character plan to restore Slytherin's reputation?
3rdb10yIs the Half-Blood, Legilimens, Snape sending a message to Quirrell with the SPHEW setup? Harry's use of Slytherin messaging and Margaret Bulstrode's Time-turner declare a Slytherin confederate, if Snape has looked. [Snape requested the check of Harry's time turner after Azkaban (para 62.99)] "a successful Legilimens was extremely rare, rarer than a perfect Occlumens, because almost no one had enough mental discipline." (Dumbledore, Snape, Mr Bester, presumably Quirrel) "Harry noticed that he was confused. And his threat estimate of the Head of House Slytherin shot up astronomically." [Rianne being memory-charmed would be required for information security if she was part of the SPHEW setup using Bulstrode's time-turner, perhaps also in tuning Jaime Astorga's fall to Daphne's Most Ancient Blade. If Hermione or another SPHEW member, (Tracey?) remembers that Quirrel has permission to teach the Killing Curse, the dynamics change.]

I have begun blogging an extended discussion of HP:MOR at quirrellinvenice.tumblr.com. Read it!

3gjm10yThose seem to have been a very long "few hours"...
2HonoreDB10yThis looks interesting! I'll be following it. It seems like a very ambitious project. In particular, approaching a piece of serial fiction as a classically structured work is possibly doable, but seems scary. The shape of the story can vary in the author's mind from chapter to chapter, so you'll be picking up contradictory clues, and end up seeing the story as a whole as a superposition of different patterns (or multiple time-displaced instances of a single one; I agree that Harry seems to be starting a second hero's journey before finishing his first.)

On #lesswrong, br1an mentioned that he wanted "to start an enjyn project to do a high quality professional grade audiobook production of HPMOR". (Enjyn is a lot like Kickstarter.)

moshez apparently listens to a lot of audio material ('escapepod, podcastle and with a little help'), and says "when they're done by a freelance voice actor, they always say how they can be hired", which suggests that VAs might be pretty cheap. One might only need a single VA, which is how a number of professional audiobooks like the Discworld books are done, a... (read more)

3br1an10yThanks so much Gwern! I was actually planning to just try and do a first chapter or two sample with whatever agreeable actor I could lay hands on and a friend's home recording studio, but seeing if there's interest first couldn't hurt! Glad to introduce myself to some more of the community too!
3drethelin10yThe best example for a single VA doing a great job is Stephen Fry doing the actual Harry Potter books.
2br1an10yThat's my dream, that somehow someone who knows him has shown him MoR and he loves it and will somehow become convinced to do this audiobook for us for free, or for whatever we manage to raise :-)
0drethelin10yunfortunately a quick googling gives me a ball park of over 100 thousand SO FAR, based on voices.com's prices. I don't know how feasible that would be to kickstart/enjyn. We might have to shoot for a level below "professional grade"

In a couple of conversations with Fred and George, references are made to some prank involving "kevin entwhistle's cat". Do we know what that refers to?

If anyone's looking for an example, Chapter 27 has a reference in the fourth paragraph.

2Sheaman377310yIt's a Noodle Incident [http://tvtropes.org/pmwiki/pmwiki.php/Main/NoodleIncident].

Rather belated (and possibly noted already), but in case there was any lingering doubt as to Mr. Hat-and-Cloak's identity:

(Chapter 35): Mr. Hat and Cloak gave a whispery chuckle. "Indeed," said the whisper. "With the murder of one student five decades ago being the exception that proves the rule, since Salazar Slytherin would have keyed his monster into the ancient wards at a higher level than the Headmaster himself."

(Chapter 49): Professor Quirrell sipped from his own waterglass again. "Well then, Mr. Potter, I shall freely tell y... (read more)

3Sheaman377310yThat has been pointed out before.
0endoself10yNo way. That would be too expected,

Oh come on, this is your chance to say the most flame-worthy thing you can come up with. Don't just squander it!

(ch67)

and he should be thinking of hypotheses and ways to test them

It's always delightful to see a potential enemy successfully subverted.

Oh, yeah, the play-fighting was fun too, I suppose.

Something occurred to me lately about the story. It seems likely that there's another character in the shadows (if not more then one).

What exactly has been going on with Nicholas Flamel?

He exists within the story, Dumbledore has consulted with him. The philosopher's stone is still being hidden at Hogwarts, and presumably Voldemort still wants it.

This seems like a decent hypothesis on who/what Quirrell is if he isn't Voldemort.

0Desrtopa10yQuirrell is canonically Voldemort, that's not a secret.
1Sheaman377310yThere is a vast difference between being possessed by Voldemort and actually being Voldemort.
  1. It's been established that we don't have the next "proper update" yet. Do you have extra private information that indicates that it won't be soon, or are you abusing the word "established" grotesquely?

  2. I would rather have the next "proper update" a bit sooner, than have it a bit later but have an extra chapter of omake first. I doubt that I am unique in this.

  3. Eliezer has indicated (in author's notes) that he thinks making him feel guilty about updating slowly will tend to make him update slower, rather than faster. This see

Re: chapter 70...

A nice capsule summary of the problem with endorsing non-instrumental heroism.

That said, Hermione raises a decent question that gets lost by the end:

"maybe people who are going to be heroes, will be heroes no matter what. But I don't see how anyone could really know that, aside from just saying it afterward."

Dumbledore has a clear opinion on the matter, and he does have some credibility, but he isn't showing his work. And Hermione's skepticism seems warranted.

If Hermione is actually interested in finding out, it would seem th... (read more)

1[anonymous]10yWell, if it was Transfiguration, it would be really important that none of the particles escape into the air. I think we're supposed to infer that there wasn't so much smoke as to be objectionable for its own sake--if there was visibly a lot of smoke, Harry probably would have noticed it behaving oddly, instead of having to rely on smell.

"(Hermione was starting to worry about what exactly the impressionable youths of the Chaos Legion were learning from Harry Potter.)"

Hah!

6Nominull10yThat line put me in mind of chapter 21, where Hermione says that Harry Potter is one of those rare cases where she can't tell Good from Bad just by looking. She can, she just doesn't want to admit he's Bad, because of their friendship and possible romantic entanglement. Interestingly, the chapter is entitled "Rationalization"...

I am confused as to why Quirrell/Voldemort would leave behind the false clue of the animagi potion. Revealing an escape mechanism that may prove usefull later doesn't make sense.

So now Amelia Bones changed the rules of visitation at Azkaban to prevent forming a new animagus. However, the prison is still vulnerable to an unregistered Animagus from escaping (unless they have detection methods?). Escape like this would still lead to a Sirius style manhunt unless a realistic corpse was left behind.

Interestingly, Sirius whom in this fiction is probably a... (read more)

I am confused as to why Quirrell/Voldemort would leave behind the false clue of the animagi potion. Revealing an escape mechanism that may prove usefull later doesn't make sense.

The reason for it was actually ingenious- look at the actual result:

Albus sighed. "Indeed. But even if he has tricked me perfectly, we may at least rely on the conclusion that it was not Harry Potter."

Since Quirrellmort wanted to divert suspicion from Harry in the event of some mishap, he left what amounts to a "VOLDEMORT WAS HERE" flag at the scene of the crime. Not even Mad-Eye Moody would suspect that Voldemort and Harry Potter pulled off the prison break together.

2hamnox10yTruly, it is insanely mind-boggling to think about. I'm still freaking out about it myself a little, even as I, a reader, was privileged with a much broader perspective on the circumstances leading up to the event than the characters. Except maybe Quirrelmort, he's a grand mysterious meddler.
3orthonormal10yOh, I see it now: the intermittent glitch is Tom Riddle, who disappears when Quirrell is in zombie-mode.
4Sheaman377310yI thought that the intermittent glitch was there being two Harry Potters, when he's using the Time Turner. Though, theoretically, they should have noticed this before, given that Harry's not the first student to use one. The permanent one could be that the name Tom Riddle is constantly juxtaposed with Quirinus Quirrell.
4TobyBartels10yThat one's so obvious that even a couple of Gryffindors ought to be able to figure out what it means.
3Sheaman377310yEven when they don't know that Voldemort's real name is Tom Riddle?
3TobyBartels10yGood point! They ought to be able to locate the hypothesis that it really is two people in one, but with no understanding of the second person's importance, they might well just consider it "anomaly".
0Desrtopa10yConsidering who it is they're dealing with, I'd think that a more immediately available hypothesis is that Tom Riddle is another identity worn by the person who now calls himself Quirinus Quirrel. I certainly wouldn't discount the possibility that magic related to true names [http://tvtropes.org/pmwiki/pmwiki.php/Main/IKnowYourTrueName] exists, and if so, anyone with an interest in concealing their identity in the long term is likely to have messed around with it.
0Acrinoe10yTime Turners and the Marauder's Map didn't mix in canon works. Double entry glitch seems likely. I can't recall, did canon works show Harry in the Marauder's Map despite being under his invisibility cloak? I would assume from dialog in HPMOR that it wouldn't be able to detect him as it's ability to hide is such that he can elude even death's detection.
0TobyBartels10yLupin saw Harry & friends on the Map while they were under the Cloak in Book 3.
0Sheaman377310yYes...long before Rowling decided to make Harry's cloak legendary. I don't have any solid proof of it, but too many things don't match up if you assume that the Potter Cloak was a Deathly Hallow from the beginning, starting with the fact that no one realized that the idea of a functioning heirloom Invisibility Cloak is apparently an oxymoron, and definitely including that Moody's eye (buffed to an insane degree in MoR) and a toy invented by four pranksters in their teens (also buffed in MoR, if to a lesser degree) are able to see where Death may not.
0TobyBartels10yYeah, things don't make much sense in canon, but what do we do about it? Eliezer has been fixing this continuity glitch by going through the things that could beat Harry's cloak and buffing them up, not (as he might have) by denying their powers over the cloak. (I think that there's a slogan in here somewhere, to the effect that only an Epic Item can beat an Epic Item, and Harry's cloak is Epic.) So Moody's eye must be the Eye of Vecna/Vance, and the Marauder's Map must be an invention of the Founders of Hogwarts (only lightly tweaked by the Marauders, assuming that this is the same group as in canon). So it goes right along with what Eliezer's been doing that the Map should see under Harry's cloak. The Four Founders are better than Death at finding people, after all.
1Desrtopa10yIt's possible they were tricked in believing they had ever captured him in the first place.
4TobyBartels10y"I'm not serious!"
2TobyBartels10yI don't deserve all of these upvotes; it's not my idea originally.
1Pavitra10yIt's probably Pettigrew in the cell.
0Unnamed10yThere was some discussion of that in thread v [http://lesswrong.com/lw/30g/harry_potter_and_the_methods_of_rationality/]; search the page for "Sirius".

It just occured to me that HRMOR strikes me as a bit similar in mode to Ender's Game in the way that Prof. Quirrell set Harry up right at the start to being "different and better" to isolate him and force him to excel. He caves a little with offering advice, support, and hints,; whereas Graff would have told Ender he would have to figure it out how to win or he'd find another special kid.

I'm somewhat surprised that Dumbledor didn't intervene, say with a side quest, to bind some friends and allies to Harry. Guess he likes what Quirrell brings to the table.

I really enjoy the deep game being played out in this story.

3Normal_Anomaly10yThe Ender's Game parallels are definitely striking, and I like them. That was a fun book, and I am enjoying seeing it played with by an author so bluntly opposed to the "whiny hero" trope. That may have been part of the purpose of Dumbledore pushing Hermione into being a heroine: he wanted Harry to have an equal partner instead of being isolated at the top.
3[anonymous]10yThe similarities to Ender's Game are rather striking. So much so that the parallel might be a little belabored at this point: I've noticed a number of reviews saying that they'd like to see less of the "Quirrell's Armies" business at this point, and I tend to agree. I do agree that the "deep game," if by that you mean trying to suss out Quirrell's and Dumbledore's ulterior strategies and motivations, is quite fun.
5Nominull10yI dunno, I liked Ender's Game, and I would have liked it better if it had been written by the Wise Master instead of a crazy person. The Houkago Wartime parts aren't my favorite parts of the Methods, but I sort of suspect that they are not in competition with the parts that are - I suspect they are easier to write than the more mainstream plotty parts, and so they may well act to help the story keep being written, by giving the Wise Master a relatively easy, unintimidating place to start writing.
6FAWS10yDownvoted for pointless random Japanese. There are several perfectly serviceable English terms starting with extracurricular, I don't think houkago is even the most fitting Japanese word and it's not part of the standard fanfic vocabulary leaked over from anime fandom.
0Nominull10yIt's not just pointless random Japanese, it's a pointless random anime reference! :-)
2[anonymous]10yAt this point, this thread is the #1 search result if you google "Houkago Wartime". And the other search results made me think it would be best not to click-through at work.
2FAWS10yWell, fair enough. I thought people still translated things like that, but apparently not when it's a proper name and language mixed to begin with (some fictional band calling itself "Houkago Tea Time", apparently). References usually work best if people unfamiliar with the source either never notice anything odd or only that there might possibly be a reference to something. In this case the context allows a very confident guess on what's meant so you probably only shortly confuse people, and if you think packing in the reference is worth that that's your prerogative. Downvote removed.
2[anonymous]10yUpvoted for "instead of a crazy person," because it made me laugh.

What's lately?

I think that it's getting better from the 50s, but I'm not sure that it's back to how good it was from the 20s. (Well, more or less; I don't want to have to defend precisely what I just said. But you get the idea.)

Prediction/Speculation:

The first half of the first year is over in HP MOR. Prof. Quirrell's degraded health and the Curse of the Defence Against the Dark Arts professor are looming larger.

I speculate that Voldemort/Quirrel'smotivation in breaking Bellatrix out of Azkaban is insurance for a new body/host in the near future. I imagine that a willing host is not only easier to possess but might enable him with more of his powers.

5Sheaman377310yThis seems possible. However, picking a host that's at the top of the Most Wanted list isn't exactly the most intelligent of plans.
2drethelin10yThe suitability of the host in terms of power and close connection to Voldemort is probably much more important, especially considering how easy it is to travel stealthily in the wizarding world. It was mentioned for the resurrection spell that Voldemort would go out of his way to use his closest follower, most powerful kin, most powerful enemy etc.

Did anyone else not get the fanfiction.net email notifications for these new chapters? I didn't know there were new chapters until I saw this thread.

7Sheaman377310yI did get the ff.net notifications. You may want to double-check your settings, you might have changed something on accident.
0NancyLebovitz10yI got ff notifications, too.

I'm curious: did the "plausible deniability" theme of chapter 72 arise from the very beginning, because of Harry's explanation, or did you come up with it later in the chapter and then reinforce earlier scenes to make it more cohesive?

The Rachel Aaron interview mentioned in the latest Author's Notes update should probably appear under celebrity endorsements. I should probably post that as a review, but right now I don't feel like registering an account there.

Has Eliezer said how long the story will be? How many chapters the full story will have, or do we possibly have an expected ending date? I've read and enjoyed the first several chapters, but i'd rather have the entire thing when it's done instead of waiting for each next chapter. The current author's notes state that there is a predetermined ending to the plot arc, but i haven't seen an estimate of how far along the story currently is.

Ch 50

And Harry had reached into his pouch and pulled out some odd books, loaning them to her on condition of complete secrecy, saying that if she could comprehend those books it would change the pattern of her thinking enough that she'd never fall into harmony with Parvati again...

What sort of books would Harry have lent to Padma?

As of Chapter 70, we now have both Patil sisters acting together, probably on an adventure of sorts; I wonder if we'll see any evidence of her recent reading!

4Pavitra10yI assumed he gave her a copy of Gödel, Escher, Bach.

That's not how time-turners work in canon, nor in this fic (other fics notwithstanding). See TVTropes:Stable Time Loop.

Ch 68

the Defense Professor couldn't help anyone become the sort of hero that was worth becoming, and that he wouldn't even understand the difference

Damn, another good line! Where do you get all this, Eliezer?

ETA:

Ch 69

it occurred to Hermione that there might be a lot more viewpoints on the subject than just four.

Am I just in an agreeable mood today, or is this really that good?

EATA:

And the end, of course, is the Crowning Moment of Awesome.

2[anonymous]10yMy favorite was "...she was suddenly realizing just how large a difference had sprung up between Hogwarts students who'd signed up for all of Professor Quirrell's extra-curricular activities, and students who'd had years of being taught by the worst Professors ever to go Professing." I dunno, I laughed.
4major10yAlso, it's a hint. With the previous generation so weak in Battle Magic (due to Voldemort's curse - and this was discussed before, I think), it was part of Professor Quirrell's plan to train up Harry's schoolmates as well, so he can have a decent army someday. It's easy to miss it because of the funny. Eliezer does this kind of misdirection all the time.

Ch 68

I thought, once, that I knew such a man, but I was mistaken...

A great line, at least for those of us who know the canon history. One might hope that Dumbledore would have learnt a lesson from this (the lesson that Hermione has no need to learn), but apparently not.

ETA:

Ch 69

Well, maybe he did know!

Eliezer works better when we leave him alone in a room and say that hes doing a good job. Which he is ^^

I'm sorry in advance if someone already has mentioned these ideas but I'm not sorting through 1000+ comments to find out

Quirrel/Voldemorts ultimate goal with battlemagic is to teach the students of Hogwarts how to be more useful soldiers in an army to be lead by Harry. The purpose of the three armies is obviously a continuation of this plan, with the goal of teaching harry to be a good general, giving Harry a platform to develop a cult of personality around himself (an important thing to have for any aspiring Dark Lord), and finding and developing lieuten...

1MatthewBaker10yI dont think the story will be that long, but if you write that as an alternate ending ill read it.
0wedrifid10yWar with Russia? Because that usually turns out well!

Hypothesis: Quirrell is positioning Harry to be forced to figure out how to dissolve the wards at Hogwarts. (or at least that's the branch of the Xanatos pileup we're on.)

4FAWS10yI think that in your case it might be because you as a writer have outgrown that story. I couldn't stomach reading beyond the first chapter of the original Elcenia (I'll certainly give the rewrite a chance though) and while HTHT had some nice touches from the beginning it's rather bland and sometimes cringe-worthy. Once Luminosity gets going there is a night and day difference in quality. At first I thought it was because world building and characters are your weak point, but now I'm pretty sure it's because you have just become that much better. You introduced a somewhat interesting moral dilemma in HTHT recently, but the world still doesn't feel alive and the mages still don't feel like a credible threat or in any way interesting as antagonists. I'm not sure if that's just because you are limited by what you did earlier (it seems like the setup necessitates that the mages continue to be idiots collectively or it's game over, and the room for the protagonists to lose in important ways without ending the story seems very limited), but there is simply no comparison to your take on the Volturi as far as villain quality goes. Another problem might be the genre: HTHT seems to be somewhere between a straight take on mahou shoujo and a deconstruction. I think the protagonists are too old, and the world, simplistic as it is, too constrained by logic for a straight take to work, and it's too much of a straight take to work as a deconstruction. If you could find a way to break out of the story you were originally writing and turn it into a story actually worth your time you would probably find the experience more enjoyable. You already seem to be doing that to some extent. If you are holding back because you don't want to change the tone too much please feel encouraged to stop worrying about that ;)
2Alicorn10yNote that both Elcenia and HTHT have their origins in a collaboration, although Elcenia's was longer-lived. HTHT's co-creator (who is very invested, in general, in straight-up mahou shoujo tropes) was no longer on board by the time I started publishing, but I didn't feel like I was free to arbitrarily discard bits of the original concept. But I think it's mostly a matter of my having improved as a storyteller, as you say - that, and I'm a lazy, amateur artist, which makes webcomicking an awkward juggling act between leaning on the writing and failing at "show don't tell", and leaning on the art and having everything be incomprehensible and take forever to draw. At this point I'm not having fun with it, but I feel obliged to finish it (in part on the urging of my erstwhile co-creator). That's not exactly inspiring me to new heights of quality. Luminosity is sort of collaborative in the sense that I'm using a borrowed world, albeit with no direct participation from Meyer herself, but I honestly do not think worldbuilding is my weakness, nor character creation (Radiance in particular mostly runs on characters who are original or so far diverged from their canon origins that they might as well be).

Fanfiction.net user Black Logician has announced Harry's Game, a spinoff of HP:MoR which branches out around Chapter 65-67 of the original fic. From his post at the HP:MoR review board:

...Hermione has already formed SPHEW. Quirell though doesn't dismantle Harry's army, but goes for an alternative condition to make the army wars more of a challenge to Harry. ...

Please use ROT13 for spoilers when discussing Harry's Game.

I approve of the Enchanted Forest Chronicles reference.

Ouch (ch 68):

Minerva was going over the Transfiguration parchment due Monday, and had just marked down to negative two hundred points a fifth-year parchment with an error that could have potentially killed someone. During her first year as a professor she'd been indignant at the folly of older students, now she was just resigned. Some people not only never learned, they never noticed that they were hopeless, they stayed bright and eager and kept on trying. Sometimes they believed you when you told them, before they left Hogwarts, that they must never try

2knb10yWhen I read that I assumed it was a critique of people who are bright enough to plausibly create an AGI but not bright enough to make sure it is friendly. They shouldn't "try anything unusual".
2gwern10yI took it as yet another veiled criticism of the original books, although I'll admit I don't offhand remember any transfiguration mistakes in Order of the Phoenix.
3Jonathan_Graehl10yI only read the last book (or two). Maybe you're right, but I took it as an expression of frustration with well-meaning but net-harmful people in some area of Eliezer's interest.
2Risto_Saarelma10yLooks definitely like a real-world reference to me though.

I don't like some of the changes to the chapter where Harry and Quirrel first go to Mary's Room. The lack of any transition sentence between Harry being shocked and the mention of the crushed beetle make it almost sound like Harry is shocked by that, which is obviously not the case. The earlier version was better. At minimum, there should be some sort of transitional note like saying how he didn't see the beetle.

1Eliezer Yudkowsky10yThere weren't any changes to that chapter...?
0JoshuaZ10yHuh. In that case my memory of the chapter ending isn't accurate. I remembered there being more of a pause between Harry's shock and the crushed beetle. Rereading it I got a bit jarred because it almost read like his shock was over the beetle.
3NihilCredo10yPerhaps you're mixing it up with the final chapter of the first Dementor destruction, where the closing line about the empty tattered cloak was shuffled around a bit.

Eliezer has posted a new chapter (the 73rd) and I've started a new discussion thread (the 8th).

Is this thread the right place for asking when I can expect the next chapter by?

Just finished the existing chapters. I may have some fan art on the way.

So, I was curious to see how each chapter was getting reviewed. Here are some numbers as of a few minutes ago:

The reviews cover a total of 856,252 words, more than double the size of the fic itself.

The 10 most reviewed chapters are:

  • chapter 05: 758 reviews
  • chapter 01: 411 reviews
  • chapter 10: 387 reviews
  • chapter 09: 358 reviews

  • chapter 47: 305 reviews
  • chapter 17: 299 reviews
  • chapter 08: 294 reviews
  • chapter 70: 282 reviews

In terms of average words per review, the top 10 are:

How long until the next update?

1Alicorn10yShhh! Eliezer is the type of writer who does not hold up well when asked about that.

Just noticed, they new matrix omake.

I found it awesome, but noticed that the last line is a plot hole. Even if the world doesn't run on mathematics, that doesn't preclude physics textbooks.

After all, humanity must have understood how the world works well enough at some point to built the AIs.

3Pavitra10yI kicked myself when I read it for not having considered the doesn't-run-on-math possibility before. Consider what Neo knows: the world he grew up in, which resembles ours, is really a computer simulation. Which features of that world should he most expect not to hold in the real world? Near the top of the list should be that the fundamental laws of physics look suspiciously like a computer program.

RE Chapter 64: Would a Dragon Ball Z o-make be possible? Or is there just too much stupid in it to get rid of?

3Desrtopa10yThe trouble isn't so much that there's too much stupid to get rid of, but that if you get rid of all the stupid, there's hardly anything left. The setting of DBZ is pretty much baloney all the way down. Although an omake doesn't really require much material, so I suppose it might be possible to pull something off.
1Carinthium10yI'm not sure if anybody's seriously writing this up, but I'm bored so I may as well make some points just in case. 1- Going by the manga, Krillin's Destructo Disk move (presumably made based on first use when training for the Saiyans post-Raditz) can literally cut thing through anything. Going by the anime, Cell blocked one but he's several sagas after the start. 2- There is an ACTUAL AFTERLIFE in the DBZ-world (and they know it- Krillin died and was brought back, for one thing). For an ordinary person this might not mean much, but a rationalist acting under the assumption is going to seem insane. 3- Ironically, there is one point where being rational MIGHT work to a character's disadvantage. After Goku idiotically believes Raditz's claims to have reformed (his tail has been grabbed making him vulrnable), Raditz knocks out Goku making the situation appear hopeless. This is solved by arguable deux ex machina (I can't quite remember if it was foreshadowed)- Gohan gets angry, and manifests enough power to seriously wound Raditz and give the good guys a fighting chance. Gohan's just a kid, so if he were rational he'd probably stay out of it since he doesn't know about his hidden power. 4- The saiyan Royal family has an Artificial Full Moon technique, which factoring for power loss to make it multiplies their power level by 10 (in terms of actual effectiveness going by the series it rises considerably but not that much). There are pros and cons to sharing it of maintaing power v.s effectiveness of the Saiyan race.
1Pavitra10yThe obvious focus would be the not-quite-eponymous wish-granting [http://lesswrong.com/lw/ld/the_hidden_complexity_of_wishes/] dragon [http://dragonball.wikia.com/wiki/Shenron].
2Carinthium10yThe obvious things to do with it (mass-immortality etc) are undermined the premise- from what I remember of the manga (good read when out of brainpower), Kami created the Dragon Balls so that mankind would have a hope even in the darkest of times- he failed to anticipate the Dragon Radar which made finding them trivial. Upgraded Kami would probably realise that given the power of Shenron, he could create the Dragon Balls in such a way that, directly or indirectly if necessary, he could mold the world and prevent such dark times in the first place. It would then be down to whether he was smart enough to WANT everybody to be immortal.

ARRR!!! I just started going to the New York Rationality group, and next week when they're doing an actual HP:MOR meetup, I'm going to be in.... San Francisco, of all places.

Don't supposed the meetup could be Sunday....?

0Danylo10yOh, send me a link to this rationality group.
0ata10yRaemon might have been referring to the New York OB/LW meetup group [http://www.meetup.com/Less-Wrong-Overcoming-Bias-NYC/].
2Raemon10yI was indeed.
0gwern10yMuch the same thing happened to me - I live on LI about an hour from NYC, and I flew out to SF in part to meet LWers... and then I read in yesterday's MoR that Eliezer is out in NYC organizing stuff there. Consarn it!

Do not mess with time note - This also should result in aborting the mission since some terrible paradox occurred and you DO NOT mess with time.

Such loops are stable even without any paradox. The extent to which one can deduce whether bad things happen depends on the psychology of the individual and existing priors.

Define "lately."

Ch 69

Labour or Conservative or Liberal Democrat

I'm surprised that Harry bothered to mention the LimDems in 1992. graph

ETA: The graph is a bit misleading, since the low point in 1992 (April) hasn't quite happened yet (right?).

His parents probably voted Lib Dem.

1TobyBartels10yGood point!

A prediction I made a while back, posted here for posterity. Rot13'd to avoid spoilers.

Fnagn Pynhf vf Avpubynf Synzry.

If anyone has made this prediction before, I'd love to see it discussed.

0Sheaman377310yIf I recall correctly, the idea was brought up a few discussion threads ago. I don't remember much coming from it, though.

Also, do we know offhand:

1) What the shield is? I want to say Shield of Hufflepuff, but googling that didn't produce anything useful. Is it something I should know about?

2) What the flash of gold is? I have a vague feeling of something being introduced earlier in the story that'd be relevant, but I can't remember.

8JoshuaZ10y1 - Presumably it is the original seal of Hogwarts, hence it has the symbols of all four founders? 2- My guess is that the flash of gold is Fawkes since Fawkes is described earlier as red-gold and I think at one point as having "golden flame" and since Fawkes really likes people who try to be heros.
1Sheaman377310yTurns out, that was a good call.

"Because you are a responsible git, just like your dad." Sirius sighed and ran his fingers through his hair. It was still a bit long, but much neater than Harry remembered. "Coming back the way you did," his godfather said after a moment, "you have a lot of advantages. But it's not everything. Maybe it's easier to feel like it's your fault than admit you can't control everything."

Harry thought about that for a moment. There was a certain… perverse logic to that, he supposed. At the same time, he felt bands around his heart, ba... (read more)

When the butterfly emerges, is the caterpillar dead? I don't think so. Life still exists, and though its form changes, there is continuity from one moment to the next. The same is true for intelligence. To say otherwise is to stretch the meaning of "death" beyond relevance.
