The illusion of asymmetric insight makes it seem as though you know everyone else far better than they know you, and not only that, but you know them better than they know themselves. You believe the same thing about groups of which you are a member. As a whole, your group understands outsiders better than outsiders understand your group, and you understand the group better than its members know the group to which they belong.

In a political debate you feel like the other side just doesn’t get your point of view, and if they could only see things with your clarity, they would understand and fall naturally in line with what you believe. They must not understand, because if they did they wouldn’t think the things they think. By contrast, you believe you totally get their point of view and you reject it. You see it in all its detail and understand it for what it is – stupid. You don’t need to hear them elaborate. So, each side believes they understand the other side better than the other side understands both their opponents and themselves.

So, you pick a team, and like the boys at Robber’s Cave, you spend a lot of time talking about how dumb and uncouth the other side is. You too can become preoccupied with defining the essence of your enemies. You too need the other side to be inferior, so you define them as such. You start to believe your persona is actually your identity, and the identity of your enemy is actually their persona. You see yourself in a game of self-deluded poker and assume you are impossible to read while everyone else has obvious tells.

The truth is, you are succumbing to the illusion of asymmetric insight, and as part of a flatter, more-connected, always-on world, you will be tasked with seeing through this illusion more and more often as you are presented with more opportunities than ever to confront and define those who you feel are not in your tribe.
