It's really hard for me to answer your first question. Basically everything about HP:MoR has been optimized to be a good story, so I'm tempted to answer "everything", but I realize that isn't helpful. But for some reason I find listing things aversive. Um. Um?

The simulation fidelity thing is actually I think equivalent to the decision theory thing; or at least, fidelity of simulation is directly correlated with decision theoretic significance. I don't anticipate being understood and thus can't muster up the energy to try to be understood, recursively. I'm sorry. But the simulation thing is basically close enough, yeah.

The simulation part makes more sense to me. You mean to say that you think every relevant mind either lives in a simulation or thinks they do?

Please forgive me for asking, but do you want an Argument that Saves everyone who would exist in Tegmark IV? Because I don't believe this gets you there.

6JoshuaZ9yI'm not sure someone in a good story would recognize that they are in a story even when it is highly optimized. From the reader's perspective Harry might be interesting but even from his perspective he's spent days in classes, he's spent hours listening to Professor Binns drone on, he's had to do tedious homework, and he's had 11 years where he was just like a lot of other very smart kids, many of whom beat him in math contests.

(The HPMOR discussion thread after this one is here.)

The previous thread is over the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread.  This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it. The latest chapter as of 09/09/2011 is Ch. 77.

The first 5 discussion threads are on the main page under the harry_potter tag.  Threads 6 and on (including this one) are in the discussion section using its separate tag system.  Also: one, two, three, four, five, six, seven, eight.  The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.

As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.

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.
