+The "discourse algorithm" (the collective generalization of "cognitive algorithm") that can't just _get this shit right_ in 2021 (because being out of step with the reigning Bay Area ideological fashion is deemed too expensive by a consequentialism that counts unpopularity or hurt feelings as costs), also [can't get heliocentrism right in 1633](https://en.wikipedia.org/wiki/Galileo_affair) [_for the same reason_](https://www.lesswrong.com/posts/yaCwW8nPQeJknbCgf/free-speech-and-triskaidekaphobic-calculators-a-reply-to)—and I really doubt it can get AI alignment theory right in 2041.

+Or at least—even if there are things we can't talk about in public for consequentialist reasons and there's nothing to be done about it, you would hope that the censorship wouldn't distort our maps of the things we _can_ talk about, or about the laws of mapmaking itself. Yudkowsky had written about the [dark side epistemology](https://www.lesswrong.com/posts/XTWkjCJScy2GFAgDt/dark-side-epistemology) and [contagious lies](https://www.lesswrong.com/posts/wyyfFfaRar2jEdeQK/entangled-truths-contagious-lies): trying to protect a false belief doesn't just mean being wrong about that one thing, it also gives you, on the object level, an incentive to be wrong about anything that would _imply_ the falsity of the protected belief—and, on the meta level, an incentive to be wrong _about epistemology itself_, about how "implying" and "falsity" work.

Briefly tell the story of the Category War?—but try to keep it brief and not-personal; the focus should be on dark side epistemology, rather than re-picking my fight with S.A. or E.Y. (maybe don't name them, but describe the abstract dynamics and link). "Everyone else shot first." Wasn't what I was trying to talk about, but I took the bait. For me, this isn't just a "political" topic—I actually need the right answer in order to decide whether or not to cut my dick off]
