Jim A.C. Everett is a Marie-Sklodowska-Curie “LEaDing” PostDoctoral Researcher at Leiden University. With training and previous academic positions in both psychology and philosophy, Jim specializes in moral psychology and intergroup processes, and much of his work focuses on how moral judgments intimately shape group processes and vice versa. Jim’s work is deeply interdisciplinary, and alongside traditional social psychological approaches he draws heavily from philosophy, evolutionary theory, and behavioural economics. Jim obtained his PhD from the University of Oxford in Experimental Psychology, after previously earning a First Class undergraduate degree in Psychology, Philosophy, and Physiology and a Distinction in his MSc in Psychological Research. Before moving to Leiden, Jim held a PostDoctoral position in the Department of Philosophy at the University of Oxford, and was a Fulbright Scholar at Harvard University. During his time at Leiden, Jim will primarily be working with Carsten De Dreu, combining his interests in moral impartiality and utilitarianism with work on intergroup conflict and cooperation.
