Update: Discussion has moved on to a new thread.
The hiatus is over with today's publication of chapter 73, and the previous thread is approaching the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread. This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it.
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, seven. The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, 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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Harry trusts Hermione. Or Harry finds the idea of failing to signal trust in Hermione even more abhorrent than possibly abandoning the girls to their fates. He needs Hermione to keep his ego sane, whether or not she's guaranteed to be able to keep her ego sane. Saying "I will override you rather than ask you for your opinion" is saying "I will be right and you will be wrong, when we disagree." That's a foolhardy claim for him to make. Hermione stopped him from doing Mad Transmutation Science without so much as doing the magical equivalent of wearing safety goggles, she's an important check to keeping his ego from driving him straight off a cliff.
Exactly. Now he should begin to see why most people in magical Britain allow Azkaban to go on, without protest.
I suggest that Harry could perhaps have managed to send a good signal - possibly even a better and visibly more sincere signal - by making his commitment with something like his typical discretion.
