Useful Delusions: The Power and Paradox of the Self-Deceiving Brain

by Shankar Vedantam

Advocating fearless rationality—an end to myth-making and myth-believing—is not just about being smart. It is a matter of privilege. If you don’t lack for food and water, for physical security or a police department that comes when you call, you might not feel the need to turn to myths, rationalizations and rituals. You may have no need for fellow members of your tribe to come to your assistance when you are sick, because there are doctors and hospitals who will do a better job. If you think of yourself as a citizen of the world because borders are illusions and people everywhere are the same, you probably haven’t lived through the kind of persecution that makes you desperate for the protection of your fellow tribesmen. It’s fine to hold secular, cosmopolitan views. But when rationalists look down on people who crave the hollow panaceas of tribe and nation, it’s like Marie Antoinette asking why peasants who lack bread don’t satisfy themselves with cake. They fail to grasp what life is like for most people on the planet.
