I had the good fortune to study with Amos Tversky at Stanford. He was the chairman of my Ph.D. orals committee. He passed away shortly thereafter, and before the Nobel Prize was awarded. Together, Amos and Danny reshaped the study of human decision-making.

In Thinking, Fast and Slow, Danny has continued their excellent work together, explaining how human judgment is shaped by two different modes of thinking: a fast, intuitive system that operates automatically, and a slower, more deliberate system that requires effort. Drawing on his decades of work with Amos, Kahneman shows how the fast system often relies on mental shortcuts that can lead to predictable biases and errors.
