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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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 do remark that Dumbledore was unable to detect Harry doing an ongoing Transfiguration while he looked into Harry's prison cell in Azkaban.

An excellent point. I was going to say that Dumbledore was also unable to detect Harry's horror at Hermione's injuries "through the link that existed between the two of them, the resonance in their magic," nor did he feel "the boy exterminate his enemy in seconds." But on inspection this doesn't actually say he could feel the spells Harry was using. And Harry's scar does not appear to react to e.g the repair of Hermione's body or the summons for the Death Eaters. The doom-sense could have a lot to do with both the strength of the magic and the degree to which it inherently clashes with the senser's inclinations or goals.

I admit I did forget about that specific incident. However, Dumbledore going cell to cell in Azkaban and Lord Voldemort attempting to subvert a prophecy predicting the end of the world in a fixed, controlled location seem like two very different things from a reader perspective. It is also implied that Dumbledore did sense Harry's magic - at least on some level. [...] But he dismisses this because he is looking for a wizard strong enough to break into Azkaban and free Bellatrix Black. Lord Voldemort on the other hand, should be immediately and unconditionally suspicious of any and all magic he senses from Harry Potter.
