Jack Glaser is a social psychologist whose primary research interest is in stereotyping, prejudice, and discrimination. He studies these intergroup biases at multiple levels of analysis. For example, he investigates the unconscious operation of stereotypes and prejudice using computerized reaction time methods, and is investigating the implications of such subtle forms of bias in law enforcement. In particular, he is interested in racial profiling, especially as it relates to the psychology of stereotyping, and the self-fulfilling effects of such stereotype-based discrimination. Additionally, Professor Glaser has conducted research on a very extreme manifestation of intergroup bias - hate crime - and has carried out analyses of historical data as well as racist rhetoric on the Internet to challenge assumptions about economic predictors of intergroup violence. Professor Glaser is working with the Center for Policing Equity as one of the principal investigators on a National Science Foundation- and Google-funded project to build a National Justice Database of police stops and use of force incidents. He is the author of Suspect Race: Causes & Consequences of Racial Profiling.
