Research Summary

Dr. Hennes's research focuses on cognitive and motivated biases in information processing and person perception, particularly in the context of contemporary sociopolitical issues such as environmental sustainability and racial and gender inequity. Much of this research examines how concern for the maintenance of social stability and preferences for restorative vs. progressive social change influence cognitive processes. Dr. Hennes also conducts translational research to develop and examine 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 practice, with a focus on sample size determination.
