How to Decide: Simple Tools for Making Better Choices

Annie Duke argues that the quality of a decision should be judged by the logic of the process rather than the eventual outcome. She introduces the concept of resulting, where people mistakenly judge their choices based on luck-driven results. The book provides a practical workbook format to identify cognitive biases like hindsight bias and overconfidence. Duke teaches readers to use decision trees, assess probabilities in percentages, and perform premortems to anticipate potential failures. By documenting the information known at the time of a choice, individuals can separate skill from chance.

This book is for analysts, managers, and anyone who feels paralyzed by high-stakes options or regrets past mistakes. Readers learn to reduce analysis paralysis by categorizing choices based on their impact and reversibility. The text provides a toolkit for making faster decisions when the stakes are low and more rigorous evaluations when they are high. People walk away with a structured method to track their reasoning, minimize emotional interference, and communicate their logic clearly to peers and stakeholders.
