Poor Charlie's Almanack: The Essential Wit and Wisdom of Charles T. Munger

Munger's collected speeches, essays, and conversations on mental models, multidisciplinary thinking, and the psychology of human misjudgment, edited by Peter Kaufman. The Stripe Press expanded edition is the definitive version of a book that had circulated for decades as a cult object among investors and generalist thinkers. Munger's core argument is that reliable decision-making requires a latticework of models drawn from multiple disciplines — psychology, physics, biology, economics, history — because reality does not respect academic boundaries. His catalogue of cognitive biases predates and in many ways surpasses the behavioural economics literature that followed. For product directors, the value is both practical — better decisions under uncertainty — and philosophical: Munger demonstrates that the quality of your thinking depends on the range of your reading. The book is long, discursive, and rewards rereading more than most business books reward a first pass.
