Chicago Rationality

Welcome to the homepage for the Chicago Rationality meet-up group. Our group includes people interested in Rationality, Effective Altruism, and more. Many people find us through weird corners of the internet like LessWrong, Slate Star Codex/Astral Codex Ten, Overcoming Bias,  Marginal Revolution, and other Rationalist-adjacent sites.

If you’re interested in hanging out in real life with other people interested in these kinds of ideas, attend our next meet-up! We typically do one “topical” meet-up per month focused on a specific reading suggested by a group member and one “social” meet-up per month with no particular agenda.

It’s ok to come if you’re not sure if you’ll fit in, if you’re not the “typical” kind of person who would attend a meet-up like this, or you’re just kind of intimidated by coming to a new social event. Feel free to reach out to us with any questions as well:

If you’d like to be notified of upcoming meet-ups and social events, please fill out the form below and you’ll be added to our mailing list. We usually send out emails a few times per month.

August 2021 Meetup: Concrete Predictions About the Future

This month we’re going to try something a little different and make concrete predictions about the future (e.g. the probability that certain things will happen by a given year). We’ll be doing it live, rather than arriving with our predictions for a pre-assigned list, so feel free to bring ideas

July 2021 Meetup: Does Political Discourse Have a Place in the Workplace?

Description: Is there a rational argument for including “political” topics in conversations at work? Or will individuals and/or companies be more productive if they exclude such topics, to the degree that is possible? What role does an individual’s background play in this, since what is considered political versus just your life may not
