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 87. The previous thread has 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, 17.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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 agree with the "undifferentiated gossiping mass" bit.
Any specific example has a corresponding counterexample. Padma Patil, for example, gets nonzero development and, IIRC, perspective time, which could go a ways to counter "undifferentiated gossiping mass" - but a male character on about her tier of importance, like Blaise Zabini, gets to enact plot and is more distinct as a single person than she is. Even Ron, who is of negligible relevance, has a named skill that differentiates him from the background. Does Padma? As far as I can recall Padma is just sort of generically informedly bright. Hermione's intelligence, gratuitous perfect recall, and magical prowess can go a ways to counter "female characters are less competent" - but the most competent characters, even if you don't count the protagonist, are all male.
It's possible that this perception of undifferentiated gossiping masses may be affected by bias in what the named characters listen to. The male population of Hogwarts might well seem like an undifferentiated Quidditch-loving mass if it weren't for Harry's tendency to fling Quieting Charms around when he wants to get out of conversation. (And, as a more literary reason, the girls' gossip is often plot-relevant whereas Quidditch jabberings wouldn't be.)
