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 110.
There is 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.)
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Don't forget, his Occlumency teacher would mention after every session that he wished he would be allowed to remember the arbitrage trick.
Eliezer has talked about how one of his main reasons for writing the story as a work of fanfiction is that it gets the audience to accept a world that is massively exploitable by the main characters, which they would have thought was a case of the author making things too easy on them if the author had actually created it. Eliezer wrote a story set in the world of Harry Potter because Rowling didn't think very hard about the implications of her worldbuilding and created a massively exploitable setting.
I don't think "didn't think very hard" get's to the point. She simply wanted to paint a strange world and didn't care.
