this goes to our LessWrong page btw

Hey! You've found the official website for KW Rationality. We're a social club for people in KW who like to talk about cognitive biases, prediction markets, Moloch, Harry Potter fanfiction, calibration, effective altruism, and becoming  e m b o d i e d.

We host free events most Thursday evenings, generally in Uptown Waterloo. Please feel free to come hang out even if you feel awkward about it, are new to the community, not like “the typical rationalists”, not an "IRL meetups" kind of person, worried people won’t like you, are part of TPOT, or anything else.

Multiple people who are now regulars had similar misgivings but found themselves having a good time! We're not for everyone, but if the content of this website appeals to you, it's probably for you.

Drop in to as many or as few events as you'd like.

We welcome people of all ages, genders, and orientations.
