Founded by a small group of philosophers over a grey New Jersey weekend in April 2003, the Moral Psychology Research Group fosters collaborative interdisciplinary research on human mentation and morality. Topics on which the group is working include moral reasoning, character, evaluative diversity, moral emotion, positive psychology, moral rules, the neural correlates of ethical judgment, and the attribution of moral responsibility. This work is everywhere informed by contemporary empirical research in the biological, social and behavioral sciences, and is frequently informed by our own empirical work in such areas as development, culture, social cognition, and brain science.
