It's a loose family resemblance term. Characterizes what might be called "Vassarian epistemology", as well as the approaches to rationality of Will Ryan, Divia Melwani, Nick Tarleton, myself, and others. Used to distinguish from Eliezer's style, which could be called rationalist or x-rationalist. Common emphases are understanding human psychology and an appreciation of cultural wisdom, e.g. religious and mystical practices.
The term "post-rationalist" seems to suggest an abandonment of rational thought. Eliezer doesn't own the word "rational," you can still use it even if you disagree with him on how to approach rationality.
I also agree that traditional knowledge, even when wrong is often based on some real observation and is worth serious consideration and investigation. Baseless superstitions and paradigm shifting phenomena both look the same until carefully investigated.
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.
