When presented with new information, are you willing to accept it and change the way you see the world?
Well, that depends on what that information is. We are only open to information in a certain margin. This margin lies between the familiar and the absurd. Whether a person is broad- or narrow-minded is merely a question of how large this margin is. Broad-minded people have a high tolerance for absurdity. Narrow-minded people only consume information that is consistent with how they already see the world.
To change somebody else’s mind, we need to start at the margin and work our way outwards. If that margin is narrow, we need to start with what they already believe, and slowly work our way outward.
