Erin Hennes

Degree: Ph.D., 2013, New York University

Erin Hennes received a B.A. in Music, Psychology, and Liberal Arts and Management from Indiana University. She completed her PhD in Social Psychology with a minor in Quantitative Methods at New York University. Following graduation, she was a Postdoctoral Fellow in the Department of Psychology at the University of California, Los Angeles and a Fellow at the John F. Kennedy School of Government at Harvard University.

Research Interests:

Erin’s research focuses on cognitive and motivated biases in information processing and person perception, particularly in the context of contemporary social issues such as environmental sustainability and racial and gender inequality. Much of this research draws from system justification and related theories to examine how preferences for progressive vs. restorative change influence cognitive processes. She also conducts translational research that develops and examines the efficacy (and potential unintended consequences) of social change interventions. Finally, she is heavily involved in the development of new methods for supporting scientific best practices, with a focus on sample size determination.
