Harry Potter and the Methods of Rationality discussion thread, February 2015, chapter 111

b_sen

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 111.

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

Confidence: 25%.

Hm... this isn't a dig at you or anything, just a thought I'm having trouble answering for myself right now, but how low does one get to set the probability of a prediction, and still call it a prediction? At which point - seems it's not 50% - should you rather say "I'm predicting this won't happen?"

Imagine that Eliezer has 100 possible ways to complete this puzzle. 25% means that the combined weight of all the other possibilities outweighs the one I've outlined, but I am still privileging the one significantly over a typical possibility. (However, lerjj has convinced me that I was most likely wrong to do so.)

It's useful to be able to simply focus on probability values it makes things less complicated than always having to shift when the probability goes beyond 50%.

It seems like it would be determined by the relevant maximum entropy distribution.
