"It's hard to think of a longer lever than better decision making, and today research in this area is advancing rapidly. In Think Twice, Mauboussin boils it all down into the key insights you really need in order to train yourself to make effective, stronger decisions."

Jeff Bezos, founder and CEO, Amazon.com

"Using lively prose and striking stories, Mauboussin teaches you how to think clearly and decide effectively. He wraps an insightful amalgam of memorable concepts and eminent good sense around a core of academic rigor. Rarely do enjoyment and value go so well together."

Richard Zeckhauser, Frank P. Ramsey Professor of Political Economy, Harvard University

"In his excellent new book, Mauboussin takes the reader on a tour de force of behavioral decision mistakes. But he doesn't stop there: Mauboussin also provides readers with concrete advice on how to avoid stumbling into some of the most common mental pitfalls. Think Twice will be a permanent feature on my must-read list for investors. "

James Montier, economist, author, former global equity strategist at Dresdner Kleinwort Wasserstein

“Michael Mauboussin has long been one of the leading real world experts in the field of behavioral finance.  Here he distills the best behavioral decision research and behavioral economics to see what really impacts our most important real world decisions.  If you are about to put this book down, Think Twice, and reverse that error before you finalize the mistake!”

Max H. Bazerman, Straus Professor, Harvard Business School

“The leader of any organization knows that making the right call in a high-stakes situation is never easy. However, if you are aware of the complexities of the circumstances and you take the time to question your reasoning, more often than not you’ll make a better decision than the guys in the other clubhouse. Mauboussin's THINK TWICE helps you to gain that mental edge. That's what I expect from my team, and that's why I hope my competitors don’t read this book.”
