Never before in living memory has America been as politically polarized as it is today. We are divided by our politics, Facebook and other social media sites, and by news media. Nearly half of us have stopped talking with someone about political topics as a result of what they said in person or online. Our culture of contempt is dividing us all and making America ungovernable.

How do we use science and proven methods to reduce toxic polarization and push back against conflict entrepreneurs? This episode presents a way forward.

Peter Coleman is a leading expert on intractable conflict and sustainable peace. He's a professor of psychology and education at Columbia University and director of the Morton Deutsch International Center for Cooperation and Conflict Resolution. Peter's new book is "The Way Out. How to Overcome Toxic Polarization."
