Thinking, Fast and Slow is a non-fiction book written by Daniel Kahneman, a Nobel laureate in economics. Published in 2011, the book explores the two systems of thinking that drive our decision-making processes. Kahneman introduces the concept of the fast, intuitive, and emotional System 1, as well as the slow, deliberate, and logical System 2. Through engaging examples and research findings, he reveals the biases and cognitive illusions that affect our judgment and decision-making. Thinking, Fast and Slow offers valuable insights into human psychology and provides practical implications for understanding our own thinking processes and improving decision-making skills.
