Harry Potter and the Methods of Rationality discussion thread, part 20, chapter 90

palladias

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 90. The previous thread has passed 750 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, 17,18,19.

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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.

Chapter 90 now ends with a note that says:

There are no Author's Notes for this chapter. I will quickly remark that this chapter (and further ones up to Ch. 96) were written in advance and did not change in response to any reader speculations.

I did not notice this note when I first looked at the chapter. Does anyone know if this went up with the first posting or was edited in later? If it was edited in later, maybe we should take the random speculations more seriously. If it went up with the first post, then the same point may hold, but with regards to 88-89.

So we know, for egotistical example, that he did not add "Dumbledore had looked down over the side of the terrace and made a gesture before returning" in response to my post that included risking transfiguration sickness on the list of things for which Harry could get in trouble.

Or, at least, we know that is what the author wishes us to believe. dun dun daaaaaaaah

Eliezer added it in response to reader speculations.

I didn't notice it either. But Eliezer posted this comment on Reddit: http://www.reddit.com/r/HPMOR/comments/1hh5ph/ch90_salvaging_gender_bias_in_hpmor/cauafkt He may've felt the need to bring it to wider attention.
