elharo

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 94. The previous thread has passed 200 comments.

There is now 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.)

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: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22.

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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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 feel that neither this post nor its father have contributed to the point grandfather was making. Should I have downvoted father? Maybe I have misunderstood fathers question, was that a rhetorical question supposed to be "answered" by "Of course not!"?))

Yes, it was supposed to be a rhetorical question answered by "of course not".

Here's a Newcomb-like algorithm for getting a pony in my yard.

Open my front door and check to see if I have a pony in my yard.
If I have a pony in my yard, we have succeeded. Otherwise, use a time machine to kill my grandfather.

This algorithm works because the only stable time loops are the ones where I get a pony. You can get magically nice results by pre-commiting to create a paradox in unwanted timelines, if you can to commit to do something unpleasant in those ... (read more)
