Harry Potter and the Methods of Rationality discussion thread, March 2015, chapter 117

Gondolinian

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 117.

Plans for next chapter release:

Ch. 118 will post on March 9th, 2015, at 12pm Pacific (7pm UTC).

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

It would make me (and perhaps others) a happier person if people saying things like "it's worse to do X than Y" would distinguish between

doing X is a greater harm to the world than doing Y, and
doing X is better evidence that the person doing it is a Bad Person than doing Y.

[EDITED to add: Oh, and "actions that broadly resemble X tend to do greater harm to the world than actions that broadly resemble Y". And perhaps it's worth remarking that if you cash out "Bad Person" as "person liable to do net harm to the world", these three correspond to a typical consequentialist's analysis of consequentialism, virtue ethics, and deontology respectively. I am not claiming that this observation is in any way original.]

By "had better" with no qualification I meant the former and by "bad for virtue ethics reasons" I meant the latter, but yes, I should make the distinction even more explicit.
