It occurs to me that a Pensieve would be a powerful tool for dealing with any of the Newcomblike problems that have come up so far or are likely to come up in the future -- getting past the magic mirror, for example. Just extract any memories relating to debiasing that you might have, put them in a jar labeled do not open until Christmas, and go talk to whatever the Omega of the moment is.

Might not work like that in practice -- I wouldn't expect it to IRL, at least, since scrubbing a memory probably wouldn't get rid of the weightings that have grown around the concepts it links to. But there's enough story potential that I can see a case for handwaving that away. Starting with the potential value stability problems...

Unless being more rational caused you to decide to one-box. Actually, I can't see where someone's intuition about that problem would go from one-boxing to two-boxing as they learned rationality. Nor do I see how knowing less would make you want the Philosopher's Stone but not want to use it.

Am I missing something here?

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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