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 81, which should be published later today. The previous thread passed 400 comments as of the time of this writing, so it will pass 500 comments soon after the next chapter is posted, if not before. I suggest refraining from commenting here until chapter 81 is posted; comment in the 12th thread until you read chapter 81. After chapter 81 is posted, I suggest all discussion of previous guesses be kept here, with links to comments in the previous thread.
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.) When posted, chapter 81 should appear here.
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, eight,nine, ten, eleven, twelve.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Of course, you’re right, I forgot you could do that. In MoR at least they should have thought of it, though they didn’t seem to try it on Hermione’s. Prior Incantato* doesn’t show who was target, though, and shows only the last spell IIRC, so it’d be easy to camouflage.
I wonder if it “wandless” spells are still cast through the wand (just without holding it), or if they’re completely independent of it.
(*Edit:) The first version of this comment mistakenly said Priori Incantatem, a different spell than the one I was actually describing.
Not only does it show who the target was, it summons a pseudo-ghost if the target was the victim of a Killing Curse.
The one in canon showed at least the last four or five, I'm pretty sure.
Edit: Whoops, sorry, didn't get the context. "Priori Incantatem" is the brother-wand effect, "Prior Incantato" is the analytical spell, which we know a lot less about- I don't believe there's evidence either way whether it's possible to use it to display the target or show multiple spells.
