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. Through a combination of research findings and personal anecdotes, Kahneman provides insights into the cognitive biases that affect our judgment and decision-making. Thinking, Fast and Slow is a fascinating and enlightening book that challenges our assumptions about how we think and make choices.
