As human beings, we all live inside another kind of bubble as well: a psychological one that shapes our ideas about the everyday world. This is our “reality bubble.” Just as rocks hurtling at supersonic speed find it hard to penetrate Earth’s atmosphere, unwelcome facts and unfamiliar ideas almost never make it through the membrane of the reality bubble. It shields us from thinking about forces “out there” that are seemingly beyond our control and lets us get on with the business of our lives.
