"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, by contrast, 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 normal rules of engagement no longer apply. The brain behaves differently. We feel increasingly certain of our own superiority and, at the same time, more and more mystified by the other side."
I found the concept of high conflict extremely useful in my own life and it makes a lot of interactions make sense. Once you know what it is, you see it everywhere, and you can easily identify when you enter it. High conflict at the root of every culture war. Now that I know the topics I enter into high conflict about, I simply avoid them unless I'm in an intimate conversation with trusted peers where actual conversation can take place.
