Ra­tion­al­ity community

TagLast edit: 31 Mar 2023 14:28 UTC by Pablo

The rationality community (also known as the rationalist community, rationality movement and rationalist movement) is a social and intellectual community interested in Bayesian epistemology, cognitive bias, existential risk and other ideas related to epistemic and instrumental rationality, centered around the website LessWrong and heavily influenced by the writings of Eliezer Yudkowsky and Scott Alexander.
