Psychological Statistics, Social Psychology, Judgment & Decision Making


My research focuses on judgmental biases, with a focus on the competing influences of motivational and cognitive processes in a number of areas, including hindsight bias, planning fallacy, perceptions of offensiveness, and the spread of rumors. My most recent work has centered on medical decision making and algorithm aversion.
