The Folly Of Fools by Robert Trivers

The Logic of Deceit and Self-Deception in Human Life

A scientific exploration of how deception and, especially, self-deception evolved as adaptive strategies, enabling organisms to better mislead others by first fooling themselves. Drawing on evolutionary biology, psychology, and real-world case studies—from animal signaling to love, politics, war, and corporate failures—it reveals the cognitive mechanisms that distort perception, memory, and reasoning to manage information flow. It weighs the benefits and costs of these biases for individuals and groups, explains why honesty is often unstable, and offers practical insights for recognizing and mitigating self-serving illusions in everyday life.
