And as long as we're trying to find magical exploits, I wonder what Harry would do if he got his hands on some Felix Felicis.

For instance, if he locked himself in a room with only a weegie board (or scrabble tiles), would it be forced to spell out whatever information he needed to know? Would it only answer his direct questions, or could it just start warning him about all of Quirrell and Dumbledore and Lucius' plans and how to beat them?

I got the impression that Felix Felicis had extraordinary or possibly perfect knowledge of the current state of the world and the drinker's utility function, was thus able to calculate the best course of action over the period of time the drinker would be under its influence for, and hijacked the drinker's System 1 (and possibly motor control) until it was out of xyr system.

If it DOES hijack the user's motor control, which there is SOME evidence for, then it probably would work with a Ouija board (but scrabble tiles come in specific, limited sets-- might n... (read more)


Harry Potter and the Methods of Rationality discussion thread, part 9

by Oscar_Cunningham 1 min read9th Sep 2011725 comments


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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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