Rationalism (the online-community sense)
An intellectual community centered on applying probabilistic reasoning and cognitive-bias awareness to real-world beliefs and decisions — distinct from the 17th-century philosophical school of the same name.
Origin
Traces to Eliezer Yudkowsky’s (profiled on our Who’s Who page) posts on the blog Overcoming Bias (2006, with economist Robin Hanson), which he spun off to found LessWrong in February 2009 — now the community’s central hub.
