What it's about

Nobel Prize-winning psychologist Daniel Kahneman explains the two systems that drive how we think. System 1 is fast, intuitive and emotional; System 2 is slower, more deliberate and more logical. He shows what fast thinking does brilliantly, and the biases and errors it leads us into, from overconfidence to how the framing of a choice changes what we decide.

Why it's worth reading

It brought a lifetime of research into one book and changed how people think about judgment and decision-making, in business, medicine and everyday life. It has spent more than 500 weeks on the New York Times bestseller lists and is on the Guardian's list of the best books of the 21st century.
