Harry Potter and the Methods of Rationality discussion thread, March 2015, chapter 114 + chapter 115

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 114, and also, as a special case due to the exceptionally close posting times, chapter 115.

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

A satisfying way to defeat Voldemort would take advantage of his genuine weaknesses - his despair in humanity, his loneliness, his arrogance, his inability to comprehend genuine compassion, his need for a worthy foe. But until the latest chapters, he had not been shown to have the weaknesses of carelessness, poor planning, or leaving a dangerous enemy armed when they are in his power.

So, up until the prophecy, Voldemort can coexist with Harry. (The reverse may not be true.) So why did Eliezer add the prophecy to the mix? Was it just to set up the eventual duel between H and V?

It seems to me that that's the place to do an Author's Saving Throw, if there is one; if people reason about V as an optimization process rather than a character, they will never be satisfied by V losing a duel because V is defined by his duel-winning property. So the only winning move is not to play, but there are satisfying ways for that to happen. (In fact, I think I might write that up in long form.)

Harry James Potter-Evans-Verres only exists because of the prophecy!
