WHETHER IT’S IN A COCKPIT AT TAKEOFF OR THE PLANNING OF AN OFFENSIVE WAR, a romantic relationship or a dispute at the office, there are many opportunities to lie and self-deceive—but deceit and self-deception carry the costs of being alienated from reality and can lead to disaster. So why does deception play such a prominent role in our everyday lives? In his bold new work, Rutgers University evolutionary theorist Robert Trivers unflinchingly argues that self-deception evolved in the service of deceit—the better to fool others. We do it for biological reasons—in order to help us survive and procreate. From viruses mimicking host behavior to humans misremembering (sometimes intentionally) the details of a quarrel, science has proven that the deceptive one can always outwit the masses. But we undertake this deception at our own peril.
