You know, I'd never thought I'd stay up late (2AM!) reading Twilight fanfiction. I've done it for Harry Potter, but Twilight?
In any case, possible manipulation of Alice's precognition makes me think of Kavka's toxin puzzle
In particular, if Bella intends to do something knowing it will trigger Alice to see it in the future, but then the payoff comes through via Alice seeing it... it's not quite the same setup.
I don't think this actually occurs in the story up to where I'm currently at (I recall a scene where Bella mentions she'll do something/say something to Alice, Alice sees it in the future and explains it, Bella questions it, and Alice says that what she saw was what would have happened if she hadn't seen the vision), but I do wonder if this could apply some limitations in some form - 'I intend to do X that I really really don't want to do, but will do it because it will trigger Alice's vision which will then make it so that I don't have to do it'.
In the vein of the Harry Potter and the Methods of Rationality discussion threads this is the place to discuss anything relating to Alicorn's Twilight fanfic Luminosity. The fanfic is also archived on Alicorn's own website <strike>(warning: white text on black background)</strike>.
Previous discussion is hidden so deeply within the first Methods of Rationality thread that it's difficult to find even if you already know it exists.
Similar to how Eliezer's fanfic popularizes material from his sequences Alicorn is using the insights from her Luminosity sequence.
Spoilers for the fanfic itself as well as the original novels need and should not be hidden, but spoiler protection still applies for any other works of fiction, except for Harry Potter and the Methods of Rationality chapters more than a week old so we can freely discuss similarities and differences.
EDIT: Post-ginormous-spoiler discussion should go to the second thread. (If you have any doubt on whether you have reached the spoiler in question you have not.)
