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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

There are a lot of theories over at fanfiction.net that Harry is inside the Mirror, seeing what he wants to see.

I considered this possibility back when we were searching for Harry's solution, and found that Voldemort uses the same hand for wand and gun before and after the Mirror. I thought: If they are in the Mirror, Eliezer would have subtly indicated that, perhaps Voldemort's use of hands would be reversed since the Mirror.

Does this qualify as sufficient proof that Harry and Voldemort are not in the Mirror?

It'd be a clever tell if Eliezer wanted us to conclude they're still in the Mirror, but I don't think its absence is strong evidence of the opposite. The Mirror might not work that way, and Eliezer might simply have forgotten if it did.

(I would say it'd be clever if anyone walking into their dream-world died soon after of amino-acid chirality issues, but similar things have been done so many times that it's not very creative. Plus it clashes with the theme.)
