Yes, the nation is deeply, counter-productively divided -- and yes, American politics and American culture probably haven't been this divided in decades.... But what can we DO about such polarization? Our guest is Peter T. Coleman, a professor of psychology and education at Columbia University, where he holds a joint appointment at Teachers College and the Earth Institute. He joins us to talk about his new book, "The Way Out: How to Overcome Toxic Polarization." As was noted of this work by Publishers Weekly: "Drawing from physics, psychology, and neuroscience, Coleman's multidisciplinary approach yields fresh insights and reasons for hope. Policymakers and community activists will want to take note."
