William M.P. Klein

Bill Klein is Associate Professor of Psychology at the University of Pittsburgh. His research is primarily in the areas of unrealistic optimism, risk perception, social comparison processes, and motivated reasoning. For example, he has been interested in the relationship between unrealistic optimism about personal health risk and the processing of threatening health information (e.g., Radcliffe & Klein, 2002, Personality and Social Psychology Bulletin). Dr. Klein is currently funded by the National Cancer Institute to study the effects of social comparison and self-affirmation on colorectal cancer risk perceptions and screening adoption.
