For those who may find this a little foreign, from what I could gather, "Rationality" refers to a post-new-age new techno-religion originating in Northern California, whose soteriology focuses on artificial intelligence as the source of redemption or damnation, whose eschatology comprises of an event called Singularity, which is the accelerated formation of an artificial intelligence entity or entities, and whose normative doctrine focuses on Bayes' formula as a guiding principle and a particularly technical form of utilitarianism as an organising moral principle. Rationality has several institutions, two of which are named MIRI and CFAR, dedicated to studying the eschatological and normative aspects of the creed, respectively. The website, lesswrong, is a primary publication of Rationality, and its founding canonical texts include a Harry Potter fan fiction novella. It is one of many religions that grew in Northern California over the past sixty years or so, and far from the strangest one.
