Thinking in Bets

Thinking in Bets: Summary

She was twenty-six, and on paper her life was perfectly mapped out. A Columbia degree, an NSF fellowship, a PhD program in cognitive psychology at the University of Pennsylvania, a ready-made career as a research scientist. Then she got sick, left academia, moved to Montana, and suddenly had no money. Her brother, a professional poker player, mentioned a legal poker game in the basement of a small-town bar. Annie Duke walked in to take a look. She didn't walk out for twenty years.

Poker hooked her, not for the Las Vegas glamour but for something else entirely. She realized that at the card table she was doing exactly what she had wanted to do in the lab: making decisions under uncertainty, then watching what came of them. Except here it ran live every minute, with real money. And while she went on to win more than four million dollars in tournaments, poker taught her the one thing she believes decides our whole lives. That our fate is shaped by just two factors: the quality of our decisions and luck. Anyone who can't tell the two apart will never truly learn to decide well.

This book is about separating the quality of our decisions from their results. We'll look at why we almost always judge our own choices wrongly, how to make uncertainty a friend instead of an enemy, and what concrete tools can help us decide better starting tomorrow. By the end, you'll look at every "good" and "bad" decision you've ever made with new eyes.

Life is poker, not chess

Let's start with an evening all of America talked about. 2015, the Super Bowl. The Seattle Seahawks are down by four points, twenty-six seconds left, the ball on the opponent's one-yard line. Everyone expects the same thing: hand the ball to the star running back, who shoves it across the goal line. Instead, Pete Carroll, the Seahawks' coach, calls a pass. The pass is intercepted by the other team, and the Seahawks lose the game.
