Concept
Rationalist community

Overview
The rationalist community is a 21st-century movement that formed around a group of internet blogs, primarily LessWrong and Astral Codex Ten (formerly known as Slate Star Codex).
The movement initially gained prominence in the San Francisco Bay Area.
Its members seek to use rationality to avoid cognitive biases.
Common interests include probability, effective altruism, transhumanism, and mitigating existential risk from artificial general intelligence.
The borders of the rationalist community are blurry and subject to debate among the community and adjacent groups. Members who diverge from typical rationalist beliefs often self-describe as "rationalist-adjacent", "post-rationalist" (also known as "ingroup" and "TPOT", an acronym for "this part of Twitter") or "EA-adjacent".

But human souls which acquire knowledge of truth by the discursive method are called "rational"; and this comes of the feebleness of their intellectual light. For if they possessed the…
Aquinas Thomas, Summa Theologica, Part I
States what Rationalist community is.
It starts from wholes and universals, and makes much of the unity of things. Empiricism starts from the parts, and makes of the whole a collection-is not averse therefore to calling itself pluralistic. Rationalism usually considers itself more religious than empiricism, but there is much to say about this claim, so I merely mention it. It is a true claim when the individual rationalist is what is called a man of…
