The Cal Poly Humboldt Social Identity Lab (SI Lab) researches the social identity and self-categorization processes which underlie social and political attitudes and behavior. We examine a range of intra and intergroup processes involved in social influence and intergroup relations, including minority influence, extremism, trends toward populism, and support for non-traditional and even authoritarian leadership. Dr. Amber Gaffney leads the Cal Poly Humboldt SI Lab. We also love nature and animals (see pictures of some of our honorary lab members).

Dr. Gaffney also co-organizers the Group Processes and Intergroup Relations Pre-conference at both the annual SPSP convention () and the annual EASP conference () the SI Lab is instrumental in organizing and coordinating the conference.
