Boston Astral Codex Ten is a reader community and local meetup group centered on Astral Codex Ten (formerly Slate Star Codex), a blog by Scott Alexander covering rationality, science, psychiatry, AI, economics, ethics, and related topics. The group is based in Cambridge, MA and welcomes anyone interested regardless of familiarity with the blog. Meetups are mostly informal — dinner, games, hiking — with occasional lectures or mini-workshops. The group coordinates via Meetup.com, a Google Groups email list, a Discord server, and a Facebook group, with over 600 members on Meetup.com.

Theory of Change
As a social meetup group, Boston Astral Codex Ten does not have an explicit theory of change for reducing existential risk. Implicitly, the group supports community-building among people interested in rationality, AI, and related topics, which may facilitate knowledge-sharing, career connections, and norm-spreading within the rationalist and EA-adjacent communities that do work on AI safety and x-risk.
