At the Laboratory for Social Minds we undertake empirical investigations, and build mathematical theories, of both historical and contemporary phenomena. We range from the centuries-long timescales of cultural evolution to the second-by-second emergence of social hierarchy in the non-human animals, from the editors of Wikipedia to the French Revolution to the gas stations of Indiana. We create synthetic, deep-time accounts of major transitions in political order, with the goal of the predicting and understanding our species’ future.
