When we are baffled by the insanity of the "other side"-in our politics, at work, or at home-it's because we aren't seeing how the conflict itself has taken over.

That's what "high conflict" does. It's the invisible hand of our time. And it's different from the useful friction of healthy conflict. That's good conflict, and it's a necessary force that pushes us to be better people.

High conflict is what happens when discord distills into a good-versus-evil kind of feud, the kind with an us and a them. In this state, the brain behaves differently. We feel increasingly certain of our own superiority, and everything we do to try to end the conflict, usually makes it worse. Eventually, we can start to mimic the behavior of our adversaries, harming what we hold most dear.

In this "compulsively readable" (Evan Osnos, National Book Award-winning author) book, New York Times bestselling author and award-winning journalist Amanda Ripley investigates how good people get captured by high conflict-and how they break free.
