The Success Equation: Untangling Skill and Luck in Business, Sports, and Investing

Description

What role, exactly, do skill and luck play in our successes and failures? Some games, like roulette and the lottery, are pure luck. Others, like chess, exist at the other end of the spectrum, relying almost wholly on the skill of the players. But in every other domain--from business, to investing, to sports--skill and luck seem almost hopelessly entangled. In his provocative new book, Michael Mauboussin untangles the intricate strands of skill and luck, defines them, and provides useful frameworks for analyzing their relative contributions. He offers concrete suggestions for how to put these insights to work to your advantage in business and other dimensions of life. Among the insights that Mauboussin reveals: * When your skill is greatest in different domains (the "arc of skill") * Why you want to increase randomness when you're the underdog * Why understanding reversion to the mean is crucial * How to find the right statistic * Why social ties can greatly increase a product's chances for success Showcasing Mauboussin's trademark wit, insightfulness, and analytical mind, Skill versus Luck is a must-read for anyone seeking to make better decisions--in business and in life.

He also knows how easy it is to botch the job and has great stories--from music studios to baseball dugouts to the New York Stock Exchange--that bring statistical abstractions to life." Howard Marks, Chairman and cofounder, Oaktree Capital Management; author, The Most Important Thing-- "In The Success Equation, Michael Mauboussin helps us understand the difference between skill and luck and, importantly, how to tell how much each contributed to a given outcome. He reminds us that in fields where luck plays a big part, like investing, outcomes are of limited relevance in assessing performance. And, indispensably, he points out how important it is for practitioners 'to develop an attitude of equanimity toward luck.' I love that!" James Montier, GMO; author, The Little Book of Behavioral Investing-- "The Success Equation is a brilliant and insightful book packed with interesting anecdotes and rigorous analysis. Anyone dealing in fields that blend some combination of luck and skill--which is most of us--will find their understanding enhanced by reading it. The central role of process in such environments is often underestimated. This book helps redress the balance." Paul DePodesta, Vice President of Player Development and Scouting, New York Mets-- "Few people acknowledge or care to accept the central role that luck plays in our lives. Michael Mauboussin not only understands the separation between skill and luck, but more importantly, provides a mental framework to deal with the reality. This is an important read."
