The next discussion thread is here.
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 85. The previous thread has long passed 500 comments. Comment in the 15th thread until you read chapter 85.
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.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
So my promised followup. In order for the world not to display absolute determinism(of the sort where you can project infinitely far ahead given sufficient computing power and knowledge of world-state), then there needs to be a point at which new information is added. Alternately, the limits on the computing power of the Source of Magic's Precognition Engine impose a horizon on predictions. In the former case, some new information is added to the system - likely in the form of a quantum world-choice - that is sufficient to allow a prophecy to be made. In the latter case, the choice of timing is pure coincidence, which makes it very unlikely. It's also possible that the Source simply cannot access all possible data, but only things that have explicitly been formed into conscious thoughts - not sure how accurate predictions could be without sufficient access to the physical world, but perhaps "macroscopic and consciousness" is sufficient? IDK.
In any case, "free will" is a convenient shorthand for the idea I was getting at, which people seem to have understood, but it is not strictly accurate. I think my thought process was quite fuzzy, and you've sharpened it significantly, for which i thank you.
I'd say partial Transfiguration is pretty strong evidence that the Source of Magic is paying very close attention to wizards' conscious thoughts, whatever else its data-gathering abilities.
