What is Thinking, Fast and Slow about?

Thinking, Fast and Slow is Daniel Kahneman’s 2011 book on how we think and decide. Kahneman won the Nobel Prize in Economics in 2002 for the research he did, much of it with Amos Tversky, and here he gathers it into five parts and thirty-eight chapters.

Below you’ll find a review, a summary of the big ideas, six practical habits and six books to read next.

Kahneman won the Nobel Prize in Economics in two thousand two for work he did with his friend Amos Tversky. This book brings together decades of that research into one story.

The central idea is that your mind has two modes. System one is fast, automatic, and intuitive. System two is slow, effortful, and logical. Most of the time, system one runs the show, and it is wrong in predictable ways.

The book has five parts, thirty eight chapters, and almost two hundred thousand words, so it is a long read.

Are the studies in Thinking, Fast and Slow still valid?

The core ideas on heuristics and loss aversion are widely used, but some findings in the book, especially on priming, have been challenged in replication efforts. This is the reviewer's summary, not a formal assessment.
