Matthew Bishop (MB): Hello, this is Matthew Bishop with Books Driving Change. And today I'm talking with Peter Coleman of Columbia University, one of the co-founders of the Difficult Conversations Lab, which explores what do we do about toxic conversations, a subject that hopefully won't refer to the conversation we're having together now -- which will hopefully be a very positive conversation. But, obviously, we are at a time of increasing polarization in the world. And a lot of conversations seem to end up being more counterproductive than productive. Peter has written a book called The Way Out: How to Overcome Toxic Polarization, which is something that anyone listening to this podcast will want to know the answer to. So Peter, can I just start by asking you in one sentence, given the audience that this podcast has of people engaged in trying to bring about positive change -- why should they read the book?Peter Coleman (PC): Well, thank you, Matthew, for having me. So the reason I wrote the book is that I feel that there is significant misunderstanding of the nature of the problem of what I call “toxic polarization”, which is unlike typical forms of polarization -- it's more extreme, it's more entrenched, it's more long term. And so what I offer in the book, and I think is relevant to your listening audience, is a different theory of change. Typically, how we think about addressing things like political polarization is that we go after key pieces of the problem. But we don't understand how the problem works as a whole, as a system, as a series of forces that kind of align and feed each other in complicated ways. And this book offers an alternative theory of change, it contrasts our typical kind of scientific approach of looking for the essence of a problem, and says this problem of toxic polarization has many essences. And more importantly, these essences align and feed each other in complex ways that really make it, as a cultural phenomenon, highly resistant to change. And so it's important that we understand how problems like these, wicked problems, actually do change, and what to do about them based on science. And so that's why I wrote this book -- to offer this alternative theory of change.MB: And it is an optimistic book, fundamentally, which is interesting because you start talking about how everyone's feeling so miserable now, and this is actually a reason for optimism. Why do you make that point?PC: Well, because one of the things we've learned from the study of deeply divided societies that actually do come out of this time and pivot into a more constructive direction, is that there are a couple of basic conditions that often are associated with that kind of change. One is that there is a sufficient level of misery within the political middle -- what in ripeness theory they call a “mutually hurting stalemate”, where you are sort of exhausted and fed up and really don't want to continue to engage in the same way, and you want to do something different. And certainly in America, but in many places in the U.K. and around the world, there is a growing, exhausted, middle majority that's fed up with the political vitriol that we see, the dysfunction that we see, and really seeking an alternative. So in that way, the ground is ripe for a movement that offers people a vision for how to change. But in addition to being miserable, they need to have some clear sense of what to do. What is the alternative? What are the steps? And that's why I wrote this book.MB: I'm very struck by how you are coming at this -- as someone who, as you talked about in the beginning of the book, grew up in a very difficult situation. You weren't in a well-to-do family, your father was being pursued by violent men, I think you say for gambling issues, you ended up getting your Ph.D. after a long and difficult process and welfare support, and all sorts of things in a single-parent home. And you know many people. You identify as much with Trump supporters in some ways as you do with his critics. About halfway through the book, you say, “Dear reader, I hope half of you are Trump supporters and half of you aren't”, or words to that effect. This is such an unusual voice at the moment, given the politics that we're seeing in America, and as you also say, around the world. How do you feel we can get beyond this pro-Trump/anti-Trump mindset and get to some of these underlying systemic changes that we need?PC: My journey to some degree is unique, because I was born in a place and at a time with folks that were disenfranchised, and I was as a young person I kind of worked my way out of that. And now I live this Columbia University professor on the Upper West Side of Manhattan [life], which is a very progressive arena. So I've experienced both worlds, and have empathy for both worlds. And ultimately, I think that's the question -- is how do we create some kind of trusted process or system where people can rediscover ...
