Thinking, Fast and Slow is a book by Daniel Kahneman, a Nobel laureate in economics, that explores the two systems of thinking that drive our decision-making processes. Kahneman introduces the concept of System 1, which is fast, intuitive, and prone to biases, and System 2, which is slow, deliberate, and analytical. The book delves into various cognitive biases and heuristics that affect our judgment and decision-making, and provides insights into how we can make better decisions by understanding the limitations of our thinking. Thinking, Fast and Slow is a fascinating and enlightening read that challenges our assumptions about how we think and make choices.
