Theory of Change
Rationality Meetups believes that in-person community building is essential for developing and spreading rationality practices. By connecting people who care about clear thinking, cognitive debiasing, and reasoning about important problems (including existential risks), the organization helps create thriving local communities that can support individuals in developing better reasoning skills. These communities serve as recruiting grounds and support networks for people who go on to work on AI safety, effective altruism, and other high-impact cause areas. The organizer retreats and coordination infrastructure help ensure these communities are well-run and sustainable, amplifying the pipeline of people who engage seriously with existential risk reduction.
