We study how to reduce subtle or hidden discrimination.

Hidden biases within the mind create a gap between what people value (e.g., racial equality) and what people do (e.g., racial discrimination). Our research seeks to close this gap by understanding how these biases work, figuring out how to reduce them, and developing interventions for addressing their consequences.
