'Political science is currently in the midst of a new behavioral revolution, and Mintz, Valentino and Wayne are three of its most exciting architects. Beyond Rationality: Behavioral Political Science in the 21st Century offers an innovative and accessible framework that unifies psychological approaches to the study of politics. Masterfully weaving across insights from multiple subfields, the book is a must-read for students of political behavior, and anyone who wants a preview of where the discipline is heading next.'
