Cognitive and Motivated Biases in Information Processing in the Context of Social Justice Issues
We examine cognitive and motivated biases that may interfere with information processing, particularly in the context of contemporary social issues such as environmental sustainability and racial and gender inequality. We examine how basic psychological processes such as perceptual judgment, recall, and evaluation of scientific and media information are influenced by political ideology and preference for progressive vs. restorative change. Our empirical methods include laboratory experimentation, public opinion surveys, focus group interviews, and longitudinal field research to investigate information encoding, elaboration, and dissemination. This line of research is partially funded by a grant from the FACE Foundation in partnership with the French Embassy, with additional support from the Purdue Climate Change Research Center, the Office of the Executive Vice President for Research and Partnerhships, and the graduate school.

Benefits and Unintended Costs of Diversity Interventions
We develop and test the efficacy (and potential unintended consequences) of media-based interventions aimed at addressing bias favoring men and racial and ethnic majority group members in academic settings. Materials for the Boiler Inclusion Project (with Drs. Margo Monteith and Evelyn Carter) can be found here, and materials for Video Interventions for Diversity in STEM (with Drs. Corinne Moss-Racusin and Eva Pietri) can be found here. This line of research is partially funded by a Purdue University Diversity Transformation Award.

Improved Methods for Statistical Power Analysis
The SuperPower Project develops new methods for power analysis, utilizing data simulation and innovations in generalizability theory, guided-walk, and machine learning techniques. We also develop guidelines for determining appropriate parameter estimation when information is limited. Training materials and syntax can be found here and here. This work is funded by a National Institutes of Health R01 award. Contact Dr. Hennes for information about statistical consulting and methodological workshops.
