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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

As a simple matter of fact, Voldemort is stronger than Harry in basically every way, other than Harry's (incomplete) training in rationality. If Voldemort were a good enough planner, there's no way he could lose; he is smarter, more powerful, and has more ancient lore than any other wizard. If Voldemort were also rational, and didn't fall prey to overconfidence bias / planning fallacy...

Well, you can be as rational as you like, but if you are human and your opponent is a superintelligent god with a horde of bloodthirsty nanobots, the invincible Elder Lightsaber, and the One Thing to Rule Them All, then the story is going to read less like HPMOR, and more like:

"...HE IS THE END OF THE WORLD." Quirinus Quirrell calmly activated the toe ring he had prepared months ago, causing the capsule of sulfuric acid embedded in the top of Harry's skull (placed there earlier by an Imperiused Madam Pomfrey, in case of emergency) to break open and quickly dissolve the other Tom Riddle. Quirrell shook his head in disappointment as he felt the sense of doom diminish and then disappear, but it had to be done. He turned to walk towards the third floor corridor. The End.

Yup. So the solution is not to make your villain a superintelligent god with a horde of bloodthirsty nanobots, the invincible Elder Lightsaber, and the One Thing to Rule Them All to begin with. Eliezer took the risk of setting up an incredibly powerful villain, and it is to his credit as a writer that up until the very end he made us believe that he was capable of writing a satisfying resolution anyway.

Frankly, he still might. There are four chapters left, and Eliezer is nothing if not capable of surprising his audience. And as a Naruto fan, he might also have come across Bleach (another of the Big Three shounen series), and learned from its author already having made the exact same mistake.
