The P3 lab examines the way civic and political organizations make the participation of ordinary people Possible, Probable, and Powerful. The lab is led by faculty director Hahrie Han, political scientist at the University of California, Santa Barbara. Hahrie and the P3 lab use observational and experimental methods to study civic and political engagement, collective action, organizing, and social change, particularly as it pertains to environmental politics and social policy issues. Lab research has appeared in the American Political Science Review, American Sociological Review, American Journal of Sociology, and other journals. Hahrie has published three books. This website describes Hahrie's work and the work of the P3 lab.
