On October 19, 2018, the fourth annual Princeton Conference on Identity and Inequality brought together political scientists who study processes of inequality and identity involving class, race, ethnicity, gender, sexuality, or religion in American or comparative contexts. Scholars presenting their work included Antoine Banks (University of Maryland), Bernard Fraga (Indiana University), Mona Lena Krook (Rutgers University), Daniel Posner (UCLA), and Ariel White (MIT). Professor Vincent Hutchings (University of Michigan) analyzed the threads shared among the papers and stimulated discussion among all the attendees about how these different perspectives and subfields can be integrated in future research. The conference was organized by Professors Tali Mendelberg and Omar Wasow, both of Princeton University and CSDP faculty associates. The conference is in collaboration with IPRG (Identity Politics Research Group) and co-sponsored by Princeton's Center for the Study of Democratic Politics (CSDP), Bobst Center for Peace and Justice, Program on Inequality, and Princeton Research in Experimental Social Sciences (PRESS).
