About us
We're a group interested in rationality. We talk about science, reason, thinking, economics, artificial intelligence, and everything else we can apply logic and reason to. We like to be curious, read widely, and think about the big questions.
Many people have found this community through the blogs of Astral Code Ten / Slate Star Codex and LessWrong. If you also like those blogs, great! If not but you're still interested, that's great too!
If you are an aspiring rationalist, a nerd, a geek, a scientist, or just a thinker, we can't wait to meet you to hear what you are thinking about. We love to share ideas, discuss, debate, learn and grow together. Don't worry about being the "right" person for this group. If you like to think about ideas, you're the right person.

Doing Good Better and Effective Altruism
Wisdom Park, Findley Lane, San Diego, CA, USKeerthana will be hosting this meetup. Her description:
I recently read Doing Good Better by William McAskill, and was struck by how many of its conclusions felt counterintuitive—especially as someone who hadn’t explored Effective Altruism in much depth before.
I thought it would be interesting to unpack some of these ideas together: which ones hold up under scrutiny, which ones feel misleading or incomplete, and what kind of evidence would actually change our minds about how to do the most good—especially when it comes to donations and career choices.
If you want, you can read the book beforehand—it’s very accessible, and there’s also an audiobook version available on Spotify. If not, a short summary, review, or video overview should be enough context to participate.
Here's the famous TED Talk by Peter Singer: https://www.youtube.com/watch?v=Diuv3XZQXyc
