How to Decide

“‘The decisions you make are like a portfolio of investments.’ I believe that almost everything can be viewed as a portfolio — whether it’s a set of products a single company decides to make, the schools and jobs and skills an individual invests in, and all kinds of life decisions. The question is, how do we make sure that portfolio as a whole advances you toward your goals — even though any individual decision within it is a win or loss? In this new book, Annie provides exercises for how to decide. All of us — not just investors — should be obsessed with making better decisions.”
—Marc Andreessen, cofounder of Netscape and Andreessen Horowitz

“How to Decide is a delightful, practical guide to making better decisions in a complex world. Annie Duke explains exactly how to cut through the biases that prevent most of us from making wise choices and offers readers a toolkit for learning from the past and tackling the future in an uncertain world. I look forward to assigning this book to my Wharton students for many years to come.”
—Katy Milkman, Professor at The Wharton School of The University of Pennsylvania and host of the Choiceology podcast

“You can’t learn how to ride a bicycle by reading physics textbooks. You need to get on the bike and practice. And you can’t become a better decisionmaker by reading micro-economics textbooks. You need to practice by working through the real-world exercises in this state-of-the-art book.”
—Philip Tetlock, author of Superforecasting
