Thus it turns out that, just maybe, my effort to bring people together who disagree isn’t an exercise in futility after all. I was just doing it wrong, relying on cold facts instead of human stories. When we tell stories, our brains unite, giving us the chance to at least understand one another, whether we ultimately agree or disagree. We can break down prejudice and division—we can defeat myside bias and induce openness, if not agreement—two brains at a time.
