"'Preregistration', you describe the experiment before you perform it and open a prediction market on the results before they're in. That forces Civilization to make its own prediction in advance. It lets anybody object beforehand instead of afterwards if they have an issue with your experimental procedure, and makes them look less persuasive if they wait until you get a result they don't like, to claim something was wrong with your methodology. It guards against a scenario where people think that boring or expected results are 'failures' and don't bother to report on those, until somebody by random luck gets a misleading exciting result and reports on that."
"But, uh, I'm realizing as I say it, that none of this stuff about prediction markets is really the first thing we need to think about on a mini-Science! project the size of Project Lawful. We're small enough that we can just know about all the experiments everyone is doing, and say all our individual probabilities on them out loud in advance."
"I'm sort of flailing here, going through things in random order, as you can probably tell. In dath ilan we all sort of grow up knowing how Science! is supposed to work, if only vaguely to start with, so at no point does anybody try to teach you the whole thing all at once. There's just little pieces here and there where you learn in more detail how some bit of Science! works."
