Harry Potter and the Methods of Rationality discussion thread, February 2015, chapter 108

New long chap­ter! Since I ex­pect its dis­cus­sion to gen­er­ate more than 160 com­ments (which would push the pre­vi­ous thread over the 500 com­ment limit) be­fore the next chap­ter is posted, here is a new thread.

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 108 (and chap­ter 109, once it comes out on Mon­day).

EDIT: There have now been two sep­a­rate calls for hav­ing one thread per chap­ter, along with a poll in this thread. If the poll in this thread in­di­cates a ma­jor­ity prefer­ence for one thread per chap­ter by Mon­day, I will edit this post to make it for chap­ter 108 only. In that case a new thread for chap­ter 109 should be posted by who­ever gets a chance and wants to af­ter the chap­ter is re­leased.

EDIT 2: The poll in­di­cates a large ma­jor­ity (cur­rently 78%) in fa­vor of one thread per chap­ter. This post has been ed­ited ac­cord­ingly.

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.
