Professor and Department Head | Carnegie Mellon University



Gretchen Chapman's research goal is to illuminate the psychological processes underlying decision making and to harness these findings in the design of theoretically motivated, policy-relevant interventions to facilitate healthy and pro-social behavior such as vaccination and blood donation. Her research combines the fields of judgment and decision making and health psychology. Using both laboratory and field experiments, she tests behavioral interventions, simultaneously exploring the theoretical mechanisms of decision making and also yielding policy insights into methods for improving health behavior and health outcomes. She is a former senior editor at Psychological Science, a past president of the Society for Judgment & Decision Making and the author of more than 100 journal articles.

To at least a degree, we have been doing a few things right.
