The new thread, discussion 13, is here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With three chapters recently the previous thread has very quickly reached 1000 comments. The latest chapter as of 25th March 2012 is Ch 80.
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: one, two, three, four, five, six, seven, eight, nine, ten, eleven.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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'd just like to note that even then, Harry comes out the loser from this whole chain of events. Most importantly, he loses Draco as an ally, and suffers from knowing he hurt Draco's relationship with this father. Less importantly, Hermione has been psychologically hurt (I'd say traumatized), and won't get any personal redress. Finally, if Harry sets someone else up, he will lose the ability to expose the true culprit in the future, if he learns who that was, and so loses a powerful avenue of action against that culprit. The true culprit (or someone else) may even find proof of Harry framing Jugson, and then blackmail Harry with that proof.
The only way Harry could come out genuinely ahead is if he found and exposed the culprit, rather than frame a random enemy. Including scenarios where he could delay Hermione's punishment, or cancel it using blood debts, so that he'd gain time to search out the real culprit.
I believe a major psychological reason for people proposing so many theories for Harry's solution, some of them very impractical, is that they have an "intent to kill"; they don't want to propose a solution that settles for second best, like yours. They want Harry to win.
Go ahead and read the rest of my plot, I would say Harry has the best possible win here beyond overthrowing the entire ministry and remaking the government in his image. At least from Harry's perspective since he doesn't know that the real best win would be exposing and vanquishing Quirrelmort.
