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 95. The previous thread has passed 300 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, 20, 21, 22, 23, 24.

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

My intuition was that since a hypothetical immortal soul doesn't pass on the owner's genes and therefore doesn't contribute to genetic fitness, it should have little if any direct influence on evolutionary incentives.

It's true that an animal that somehow evolved a soul would look drastically different neurologically from a human, but we know empirically that wizards are mostly the same as muggles psychologically/neurologically, so it seems this doesn't happen to be the case. By the way, I agree with Draco's hypothesis that if souls do exist, muggles probably don't have them, since they don't seem to have gotten any other benefits from the magic patch.

I don't consider myself a particularly competent practitioner of counterfactual evopsych, so if you do, and still disagree, I suppose I'll have to update my beliefs.

Brain size would almost instantly collapse (from consuming 20% of ATP) once cognitive processing was offloaded to the immortal decision-making engine.
