Recognizing the problem is not the same as fixing it, though. I asked Kahan how he tries to guard against identity protection in his everyday life. The answer, he said, is to try to find disagreement that doesn’t threaten you and your social group — and one way to do that is to consciously seek it out in your group. “I try to find people who I actually think are like me — people I’d like to hang out with — but they don’t believe the things that everyone else like me believes,” he says. “If I find some people I identify with, I don’t find them as threatening when they disagree with me.” It’s good advice, but it requires, as a prerequisite, a desire to expose yourself to uncomfortable evidence — and a confidence that the knowledge won’t hurt you.
