"What more timely task for psychological science than to expose the roots and fruits of today’s growing tribalism (of both left and right) and the support for autocratic leaders. Kudos to this global team of scholars for revealing the emotions, the thinking, and the collectivist energy that fuel populism. A much-needed resource for interested students of psychology, sociology, and political science—and for political pundits and leaders." — David G. Myers, Professor of Psychology, Hope College"This outstanding and very timely book explores the psychological factors behind the recent rise of radical populist movements. Leading international scholars analyze the effects of motivational, emotional and cognitive factors in populist appeals both on the left and on the right, with often surprising results. Issues of identity, grievance, insecurity, nationalism, xenophobia, tribalism and uncertainty avoidance receive special consideration. This is must reading for anyone who cares about the world today, and especially for students, researchers and practitioners in the social and behavioral sciences" — Roy Baumeister, Co-author of the ‘Power of Bad’, Professor of Psychology, University of Queensland, Australia
