"Thinking, Fast and Slow" is a bestselling book by psychologist and economist Daniel Kahneman that explores the dual process theory of the mind. The book, published in 2011, summarizes research that Kahneman conducted over decades, often in collaboration with his late colleague, Amos Tversky.
The book is divided into two parts, corresponding to the two systems of thinking that Kahneman describes. "System 1" is fast, intuitive, and emotional. It is responsible for our automatic and unconscious judgments and decisions. "System 2" is slower, more deliberate, and more logical. It is responsible for our conscious and rational thoughts.
Kahneman argues that these two systems of thinking often lead to different judgments and decisions, and that our understanding of them can help us make better choices. He provides numerous examples from various fields, including psychology, economics, and business, to illustrate the ways in which System 1 thinking can lead to biases and errors in judgment.
One of the most famous examples from the book is the "Linda problem," which demonstrates how our tendency to rely on intuitive judgments can lead us to make irrational conclusions. In the example, participants are asked to consider a fictional character named Linda and are asked whether it is more likely that Linda is a bank teller or that Linda is a bank teller and an active feminist.
The book also explores how our understanding of these two systems of thinking can be used to improve decision-making in various settings, including business, medicine, and politics.
Overall, "Thinking, Fast and Slow" is a comprehensive and accessible guide to the ways in which our minds work, and how understanding these processes can improve our decision-making and reduce errors in judgment.
