• Welcome!

    This is a portal into the Bay Area rationalist community

    We value truth over comfort, and results over effort, but effort over apathy.
    You're invited to join us at the regular meetups described below. Check the calendar for other events that are open to the community!

    Welcoming Committee

    We are trying to organize events, manage directories (such as this one), provide community services, and build tight-knit groups of motivated people. If you would like to contribute to the community resources, please contact us at bayarearationality@gmail.com.

    Join us in organizing a more active community!

    Rationalist group houses

    There are at least a dozen rationalist group houses in the East Bay alone. If you're looking for housing, you can join the East Bay EA/Rationality Housing Board Facebook group.


    Some people are trying to solve the matching problem between houses and residents, contact us if you're interested in helping with this!
