My research examines how biases in our social perceptions and beliefs function to maintain systems of social inequality.

Specifically, I am interested in:
  1. why individuals who qualify equally for membership in more than one group (e.g., biracials) are categorized and perceived as belonging more to their lower status parent group,

  2. the endorsement of ideologies and beliefs that justify group-based inequality and discrimination (i.e., hierarchy-enhancing beliefs), and

  3. the structure and function of social dominance orientation (SDO), an individual difference variable found to undergird a wide variety of hierarchy-enhancing attitudes and behaviors.
