An interview with Thomas Carothers, an expert on foreign policy, democracy, and political polarization. He is co-author/editor of the book Democracies Divided, a summary of the national situations of several extremely polarized countries, including the U.S., Turkey, India, Poland, Kenya, and Brazil. I ask Carothers about what he views as the root psychological and social causes of extreme polarization, the erosion of democracy, and the rise of authoritarian leaders.
