I will throw in several predictions. I myself am not completely confident of some of those.

  1. Time-turners, prophecies and similar devices, which predict that something will happen, work by exerting some mind control upon people in the form of unexplicable urges, such as the urge to take the left turn this one time. I'm not sure how far can they go in order to fulfill themselves.

  2. The events in the magical world are not just dictated by the already-discovered laws of physics, but also by the laws of fairy tales. Dumbledore is pretty damn rational, at many points more rational than Harry (he might even be more rational overall). His reasons for having an evil Potions master aren't simply because this happens in fairy tales. The Universe liked it more if that was the case, so he was probably represented with an evil person who is highly suitable for the Potions position, or something like that. Dumbledore is most probably aware of this law. After Harry case the true Patronus and Quirrell asked him where he'd hide something, Harry gives 5 places: volcano, inside earth, deep in the ocean, somewhere in the air, and in space. Fire, Earth, Water, Air, space-thingy. He can't have said that by coincidence, and this is evidence of that law existing. Quirrell's reaction indicates he's aware of the law.

  3. Part of Voldemort is in Harry. The Sorting Hat either lied, or more likely, Voldemort isn't in his scar - Harry asked about his scar (I realized that much before it was reminded in chapter 90 or 91 and therefore have read a lot of HPMOR with that in mind), but it may still be inside Harry, just not in the scar. Evidence: his unusual 26-hour sleep cycle was probably inherited; he is exceptionally intelligent, and just 11, while his parents aren't particularly intelligent (intelligence is usually mostly inherited genetically); he is better with a broomstick than children who have used broomsticks before going to Hogwarts; his dark side seeks destruction (Voldemort appears to seek destruction too), and is very cold (from his flashback, Voldemort's voice is really quite cold). This probably happened by accident, rather than as a plot - it may be explained with the law from 2. - Voldemort tried to kill Harry, the universe interfered in the simplest possible way, although I'm surprised as to why did the universe let Voltemort find Harry in the first place then.

  4. Quirrell is not Voldemort. I'm still very perplexed by Quirrell, but it would make an awful, predictable plot to have him be Voldemort. He does appear to be a Dark wizard, the Monroe story seems implausible (he doesn't believe in others' love, why would he be a hero? Unless he did that for himself). He probably has a lot to do with Voldemort, but they were neither friends nor enemies. I don't know about the sense of doom, but it probably is connected with what happened when Harry's parents died. It appears that Quirrell doesn't know about it, either - therefore it is probably because he could not see an explanation, because the explanation involves love, and isn't obvious.

  5. Voldemort is the one who will (at least try to) TEAR APART THE VERY STARS FROM HEAVEN. He seems to be all about destruction, though I'm not sure why, and I'm not sure why does he not take the shortcuts Harry had in mind, and this is the weak part of this prediction. Perhaps it is the universe's will that people must die for a good reason, rather than having the world's strongest wizards destroyed by a handful of highly toxic molecules each.

  6. Magic is like that because it is made by humans. This is probably obvious - magic came to exist by humans, this is why a lot of it only make sense in terms of human intuitions, and not so much sense in terms of laws of physics. I'm still very puzzled by the fact that it appears to violate the laws of physics. It also sounded like magic might be a superintelligent AI, but I forgot my arguments for that.

I also wonder, what would happen if you use a time-turner to do the impossible, for example talk to your older copy, so when you see the newer copy, don't time-turn. Would it turn out that someone strongly felt like approaching you while Polyjuiced as you? Is it that nobody would ever think of that in the wizarding world? I'm sure there's a lot more going on with time-turners.

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 88-89The previous thread has passed 500 comments. 

There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.) 

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: 12345678910111213141516, 17, 18.

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.
