Fooled by Randomness

Fooled by Randomness by Nassim Nicholas Taleb is a thought-provoking book about how luck and probability shape results in the markets and how people judge success. It introduces the idea of alternative histories, the outcomes that could have happened but did not, and uses it to show why a good result does not always mean a good decision. The book explains the mental biases that lead traders to mistake random market noise for real skill, and how people naturally invent stories to explain events that were largely chance. It also discusses uneven, or asymmetric, outcomes and the large impact of rare, extreme events that later became known as “Black Swans”. Throughout, the author questions how well traditional statistical models describe markets that can move violently. Blending probability with philosophy, it suits traders and investors who want to think more clearly about risk, uncertainty and the role of luck, and it fits closely with our guides on trading psychology and risk management.
