In The Success Equation, Mauboussin explores the contributions of skill and luck, and discusses how interpreting past results through the skill-luck continuum can help leaders to make better decisions...This can be a useful way to look at business leadership [He observes that] luck becomes more important and skill less so, as people climb up the hierarchy, which also raises interesting questions about how leaders can continue to grow and enhance their skills what leaders can do, is to improve their understanding of the impact of fortune on their decisions. The Sunday Times

"I just finished reading the most enjoyable business book I ve read in a long time although relegating 'The Success Equation, ' by Legg Mason Chief Investment Strategist Michael J. Mauboussin to this category would be a grave disservice, significantly understating its sophistication and selling short its achievement." David A. Shaywitz on Forbes.com
"Fascinating. Michael Mauboussin's insights into the relationship between skill and luck are clearly and simply explained, relentlessly logical and often counter-intuitive. This makes for great reading and provides powerful tools for understanding sports and markets. Anyone who wants to understand sport or business beyond the platitudes and assumptions routinely trotted out as expert analysis should read this book." Ivan Gazidis, Chief Executive Officer, Arsenal Football Club
If you liked Michael Lewis s Moneyball, with it s mix of data and great storytelling, you ll very much enjoy Michael Mauboussin s Success Equation. Jack Covert, 800 CEO READ

ADVANCE PRAISE for The Success Equation
Philip Tetlock, Leonore Annenberg University Professor, Wharton School and School of Arts and Sciences, University of Pennsylvania; author, Expert Political Judgment
Mauboussin seems to know everything there is to know about how to skillfully disentangle skill from luck. He also knows how easy it is to botch the job and has great storiesfrom music studios to baseball dugouts to the New York Stock Exchangethat 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 skillwhich is most of uswill 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.
