Harry Potter and the Methods of Rationality discussion thread, February 2015, chapter 110

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 110.

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

Harry is the viewpoint character, and he thinks everyone is an idiot except him and Quirrell. He is in error. He has been consistently in error about this since ... forever. It's probably a character flaw that he shares with Voldemort, although Harry has a somewhat less murderous form of it.

For instance, Harry believes that the wizarding economy should be trivially exploitable via exchange with the Muggle precious-metals market. He believes this because even though he knows about half-bloods (i.e. witches and wizards who have a Muggle parent), he thinks that he is special and that nobody else ever would have thought of that.

Similarly, he believes that he is the first to come up with the idea of combining magic and Muggle science. He isn't that, either. He doesn't realize this even after he is given the (ostensible) diary of Roger Bacon.

And here's the thing ... he doesn't update about these errors. He's not particularly curious about them. "Hey, wait, there are Muggleborns; what's the chance any of them has ever had a relative in Muggle banking, finance, or economics?" "Oh, Roger Bacon was a wizard? I had better learn me some Latin so I can find out what the history of magic/science interaction has been."

This is what I admire in Yudkowsky. He is not afraid of creating a rationalist character who makes grave mistakes, and even cases where rationality leads him to do bad decisions instead of saving the day.

Don't forget, his Occlumency teacher would mention after every session that he wished he would be allowed to remember the arbitrage trick. Eliezer has talked about how one of his main reasons for writing the story as a work of fanfiction is that it gets the audience to accept a world that is massively exploitable by the main characters, which they would have thought was a case of the author making things too easy on them if the author had actually created it. Eliezer wrote a story set in the world of Harry Potter because Rowling didn't think very hard about the implications of her worldbuilding and created a massively exploitable setting.

I kinda agree, but...the Time Turners really didn't have protective shells. If you see what I mean.
