A long time ago, in the colder seasons, I asked for suggestions for a Shit Rationalists Say video. Due to other concerns it took me this long to put it together, and the meme has long since passed. However, here it is.
It is my first time in front of a camera, so I'm shakey. But I learned, and there it is.
Is "understanding human psychology" supposed to be something that distinguishes post-rationality from "x-rationality"?
No. The approach to understanding human psychology, though, tends to be broader—because post-rationalists draw on old cultural wisdom, and also because some of them read people like Freud who are often considered useless by x-rationalists. More of an emphasis is also placed on neurochemistry and nutrition. Both kinds of rationalists study neuroscience, cognitive science, social psychology, &c.
(ETA: Downvoter, fuck you, I'm going out of my way to answer a question. 'Course, now that this is here further downvotes are justified and won't be responded to with "fuck you"s, don't worry.)
