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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

The fact that so much of Harry's beliefs and actions are based on the assumption that speaking in parseltongue ensures that the truth is being spoken bothers me.

Harry believes this because

1. Quirrel told him.
2. He is seemingly unable to lie to Quirrel when speaking in parseltongue.

The first point is obviously something to be extremely skeptical of and, while the second appears to be strong evidence, it very strongly reminds me of

"I want to give you a drop of Veritaserum," Draco said. "Just one drop, so you can't lie, but not enough to make you answer anything..."

Of course Harry thinks he can beat Veritaserum due to his Occlumency training but this has never been put to the test and, even if it is the case, it has been established that there are things in the magical world that can be used to unilaterally manipulate a person's ability to lie.
