The book delves into the two systems that drive the way we think—System 1, which is fast and intuitive, and System 2, which is slow and deliberate. The author, a Nobel laureate, explores how these systems shape our judgments and decision-making. He presents several groundbreaking experiments that have shaped our understanding of human thought, revealing where we can trust our intuitions and how we can tap into the benefits of slow thinking. The book also discusses how our cognitive biases often lead to errors in judgment and affect our decision-making processes.
