Robert Jervis

Robert Jervis is the Adlai E. Stevenson Professor of International Affairs and one of the most prominent and influential international relations scholars alive today (ref). He is best known for his work combining international relations theory with political psychology, as in his breakthrough book Perception and Misperception in International Politics, which examines how the perceptions of political actors shape their behavior and hence foreign policy outcomes. As anyone who's ever taken a class with him can attest, his mild-mannered exterior conceals a razor-sharp mind and deep intolerance for sloppy thinking.
