In an increasingly polarized world, our only chance for coming together and moving forward is to learn from those who have mastered the art and science of disagreement. In this book, we’ll learn from experts who are highly skilled at getting the most out of highly charged encounters: interrogators, cops, divorce mediators, therapists, diplomats, psychologists. These professionals know how to get something valuable – information, insight, ideas—from the toughest, most antagonistic conversations. They are brilliant communicators: masters at shaping the conversation beneath the conversation. They know how to turn the heat of conflict into the light of creativity, connection, and insight. In this much-need book, Ian Leslie explores what happens to us when we argue, why disagreement makes us stressed, and why we get angry. He explains why we urgently need to transform the way we think about conflict and how having better disagreements can make us more successful. By drawing together the lessons he learns from different experts, he proposes a series of clear principles that we can all use to make our most difficult dialogues more productive—and our increasingly acrimonious world a better place.
