### What You'll Learn

How to make better decisions in an uncertain world by thinking like a poker player.

### Who This Book Is For

Anyone who makes decisions under uncertainty, which is everyone. Whether you are a CEO evaluating a merger, a manager deciding whom to promote, or someone choosing between job offers, this book will change how you think about choices, outcomes, and learning from experience.

Life is more like poker than chess. In chess, all the pieces are visible. Both players see the same board. The outcome depends almost entirely on skill. A grandmaster will beat a novice virtually every time. Chess is a game of perfect information, and the best decision always produces the best result. Poker is different. In poker, you cannot see your opponents' cards. You do not know what cards will come next. You can make the best possible decision based on available information and still lose. You can make a terrible decision and get lucky. The outcome of any single hand tells you almost nothing about the quality of the decisions that produced it.

We judge choices by their outcomes. We believe our successes prove our brilliance and our failures prove our incompetence. We form beliefs quickly and defend them stubbornly. We surround ourselves with people who agree with us and dismiss those who do not. This approach feels comfortable, but it is disastrous for learning. When we confuse good outcomes with good decisions, we fail to examine our mistakes. When we attribute our failures entirely to bad luck, we miss opportunities to improve. When we treat our beliefs as certainties rather than probabilities, we become blind to new information. Duke offers a different way. By treating every decision as a bet on an uncertain future, we can become more honest about what we know and do not know. We can separate the quality of our decisions from the quality of their outcomes. We can build systems that help…
