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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

I am surprised that using transfiguration and defeating Voldemort played such a large role in the solution.
I thought that it was much more likely that the solution would be to lose in some way, but to lose in a way that maintained hope / constrained Voldemort's actions to not be evil, and then to continue to work towards a better situation once out of immediate danger.

I also thought that the Vow that Harry had made would be the biggest key to the solution. After all, transfiguring carbon nanotubes and antimatter were things that Harry could have achieved earlier to defeat Voldemort, prior to the situation having gotten truly terrible. (He couldve done what he did to stun and obliviate Voldemort this during the entire forbidden corridor storyline). Therefore, it made sense to me that the new addition of the Vow would be critical to the solution, not just something throw in to stall for time.

Anyways, I am glad that the community collectively came up with all of the elements of the final solution as it was written.
