Joachim Israel Krueger Professor of Cognitive, Linguistic and Psychological Sciences

I came to Brown in 1991 after attending graduate school at the University of Oregon (a glorious experience; PhD, 1988) and doing postdoctoral research at the Max Planck Institute in Berlin. I study topics in social judgment and decision-making, such as self-perception, strategic interpersonal behavior, and intergroup relations. I am intrigued by the intersections of cognitive-social psychology with behavioral economics and organizational behavior. Interpersonal trust, power, and leadership are recurring themes in my research and teaching. When in a mood to transcend positivism, I explore questions of creativity and happiness. I am reluctant to consult for-profit organizations, but this reluctance can be broken with a combination of trust and money.

research overview

I have developed innovative measures of social projection and self-enhancement, a new model to explain cooperation in social dilemmas without recourse to prosocial motives, a pragmatic defense of significance testing, and a reformulation of Tajfel’s greatest accomplishment: accentuation theory. Current work is focused on the volunteer’s dilemma (why not volunteer?), the social perception of free (and other) riders, and the humility paradox.
