Edit: New thread posted here.
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 86. The previous thread has long 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: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
I was thinking that as of this chapter, Harry now had enough evidence to promote to attention the hypothesis that Quirrell is actually Voldemort. He has reason to believe that Voldemort has access to a mechanism which allows him to take control of people and give them a portion of his power, and Quirrell's apparent backstory entails his having undergone a conspicuous increase in apparent competence, much like that which Moody and Dumbledore suspect of having happened to Lockheart. And he has the assurances of the Order of the Pheonix that Voldemort was really smart, no, seriously smart, trust us, you're still underestimating him. And he knows Quirrell is heavily misanthropic and cavalier with people's lives, and also he went out of his way to remove Voldemort's premier servant from Azkaban, who might be useful to other enterprising wizards if she was taught some of the lore of Salazar Slytherin, but also, as Harry has been told, is a key component in restoring Voldemort to power.
But then it occurred to me that given the fact that Quirrell's sudden spike in competence in his backstory occurred while Voldemort was still around, not after his death, he would have to draw the conclusion that Quirrell was playing both sides back then. I've been operating under that assumption for a while, so I'm biased with respect to evaluating how obvious it should be given what Harry knows. This may be enough to drop the hypothesis below the attention-worthy threshold for Harry right now. But Harry does have the information to raise this particular question: if Quirrell is so smart, and was fighting against Voldemort, why didn't Voldemort lose, the way Harry thinks the Order of the Phoenix would have if they were up against a really creative and powerful wizard?
Primary piece of evidence against: Voldemort tried to kill Harry, Quirrell has passed up multiple opportunities to let Harry die. If it weren't for this, I'd think Harry was being a bit thick for not having considered the possibility already, but this is awfully strong counterevidence.
One person's modus ponens is another person's modul tollens. Reading this chapter made me update that Voldemort actually never tried to kill Harry.
