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.

A bat and ball cost $1.10 and the bat costs one dollar more than the ball. The intuitive answer is 10 cents, but the correct answer is 5 cents.
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.
