Great writing, again. Favorite sentence, “This is motivated reasoning achieving escape velocity from reality.”

Very much on the mark and clarifies complicated interactions; thank you. Also though I think a pure desire for power and to be on the side of power is its own motivator, with some who are very aware of the hypocrisy and illogic of their arguments.

What truly annoys me about the rationalist movement is its assumption that they are purely objective and unbiased. However, this directly conflicts with their belief that Bayesian thinking is the only way to go. All good Bayesian thinking must begin with priors, which are inherently biased.

Your point that these folks are not updating their priors, of course, conflicts with the supposed strength of rationalists—that within the framework of Bayesian reasoning, you do update your priors. The Popper in me says that these folks are stuck in an epistemic closed loop, making their beliefs unfalsifiable. They've become exactly what they hated in terms of epistemology. They've turned into good Marxists in their thinking.

I had a 20-year career in Silicon Valley as a systems reliability engineer, and honestly, I do not miss arguments with rationalists.
