About us
We read Astral Codex Ten, a blog that spans across rationality, science, psychiatry, medicine, ethics, genetics, AI, economics, and politics. https://astralcodexten.substack.com/about
You should join if you're interested in any of these topics and want to nerd out with other nerds! You don't have to read the blog to come to our events. Everyone is welcome - please feel free come even if you feel like you're "not the type of person who normally would fit in at such events".
We mostly have very informal meetups, sometimes including dinner, games, or hiking. Occasionally we have more structured lectures or mini-workshops.
Astral Codex Ten was formerly called Slate Star Codex. The author, Scott Alexander, has written over 1,500 posts. Don't worry, you're not expected to have read all of them!
If you're not sure where to start, check out this compilation of some his greatest works here from one of our meetup members:

Please feel free to come even if you feel awkward about it, even if you’re not ‘the typical ACX reader’, and even if you’re worried people won’t like you.
Children are also welcome; the park has a playground and plenty of space to run around.
When you show up, look for one of the guys in the tall striped hat, possibly near a canopy in case it rains.
