Harry Potter and the Methods of Rationality discussion thread, February 2015, chapter 112

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 112.

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

He can't because the curse or unbreakable vow he took to not harm himself didn't have release conditions. There was no purpose in putting them in. You don't set up "I can't kill myself unless I try to kill myself", because the 2nd part is useless if the first part works.

Without the second part any clone of Voldemort exploiting a bug in magic to negate the first would have a huge advantage over all the others. Given the whimsical nature of magic in this story such a bug is highly likely to exist. Voldemort is smart enough to both realize that and know that at least one clone of his would eventually find it. His only correct move is then having to find the bug first, thus wasting his time and negating the point of the curse in the first place.

There was a sequence on decision theory and value of information, which I sadly read but not internalized. Can someone who did please calculate what it's worth for Voldemort (and Dumbledore) to keep ambiguity unresolved as a preventive measure?
