Annie Duke's "Thinking in Bets" explores the principles of making smarter decisions by drawing parallels between poker strategy and real-life choices.

The book emphasizes that outcomes do not solely determine the quality of a decision, highlighting the significant roles of both skill and luck. It examines cognitive biases such as "resulting," where individuals equate good results with good decisions and vice versa.

Duke advocates for "thinking in bets," a framework that involves acknowledging uncertainty, considering probabilities, and separating decision quality from outcomes. She also discusses strategies for improving decision-making through mental time travel, seeking diverse perspectives, and fostering open-mindedness within groups.

Ultimately, the book aims to equip readers with tools to evaluate choices more objectively and learn from successes and failures.
