"Thinking, Fast and Slow" by Daniel Kahneman explores the two systems that drive the way we think and make decisions: System 1, which is fast, intuitive, and emotional; and System 2, which is slower, more deliberative, and logical. Kahneman, a Nobel Prize-winning psychologist, delves into how these systems shape our judgments and how cognitive biases can affect decision-making processes. For designers, product managers, and researchers, this book provides invaluable insights into human behavior and thought patterns. Understanding these concepts can lead to better user experience design, more effective decision-making strategies, and products that align more closely with the ways users perceive and interact with the world.
