Soon after Joe Biden became president he said in his inaugural address that wanted to bring Americans together, to forge unity. But maybe unity isn't what we should aim for. Our guest this week says instead of focusing on that elusive goal, Americans need to concentrate on what's damaging all of us: toxic polarization.

In this episode we look at what toxic polarization is, how it got worse in recent decades, and how to end it, person-by-person. We learn about the role played by Common Ground Committee and other groups— local and national— in the bridging community.

Peter Coleman has advised the Biden administration on how to detoxify America. He is a well-known mediator and psychologist who specializes in conflict resolution. A professor of psychology and education at Columbia University, he is the author of the book, The Way Out: How to Overcome Toxic Polarization.
