PEAR (Portland Effective Altruism and Rationality)

Portland, OR, USA

Hello and welcome to the hub for all things in Portland related to effective altruism and rationality aka PEAR!

Currently, we meet at least bi-weekly. We recommend the Wednesday Night Dinner Socials if you want to try PEAR out in a casual, low-key environment. We also have book clubs, article discussions, and the occasional large event. Please feel free to come out, even if, like many of us, you feel awkward about it, feel that you're not the typical rationalist or effective altruist, or worry that people won't like you, etc. We would love to have you join us as we strive to grow Portland's effective altruism and rationality community.

All events will be posted on Meetup and Facebook, on our public calendar, and sent out from our mailing list. You can also check out the PEAR Website showing our previous events we've hosted, and keep the conversation going on our Discord. If you have any other questions, please message us anytime at

Let's cooPEARate together to attain great heights, grow greater friendships, and do the greatest good. Hope to see you soon!
