Clear Thinking: The Art and Science of Making Better Decisions by Shane Parrish is a comprehensive guide to improving decision-making skills by refining the way we think. Parrish, the creator of Farnam Street, focuses on the cognitive biases, mental models, and systematic approaches that can help us make smarter, more rational decisions in both personal and professional contexts. Drawing on various fields like psychology, neuroscience, and philosophy, the book emphasizes how thinking clearly and logically can reduce errors and lead to better outcomes.
The main concept in the book revolves around the idea that our decisions are often influenced by biases, emotional responses, and flawed reasoning. Parrish argues that in order to make better decisions, we need to become more aware of these influences and train ourselves to think more clearly. He introduces mental models—frameworks that help us understand the world—and provides practical advice on how to apply these models to improve decision-making in everyday life.
