In "The Undoing Project," Michael Lewis explores the fascinating relationship between psychologists Daniel Kahneman and Amos Tversky. Their collaboration profoundly impacted the field of behavioral economics by challenging traditional views on human decision-making and judgment. Through numerous studies, they revealed how cognitive biases can lead to irrational choices, altering the way experts understand human behavior.

A notable moment in the book features a remark made by Amos Tversky about Murray Gell-Mann, highlighting the complexity of intelligence and perception. Tversky's observation underscores the often inflated self-assessment of intellect, suggesting that even the most brilliant minds may hold misconceptions about their capabilities and wisdom. This theme reflects the broader insights Kahneman and Tversky achieved in their groundbreaking work.
