Discussion questions

Kahneman describes System 1 (fast, intuitive) and System 2 (slow, deliberate). When do you notice yourself switching between them — and which do you trust more by default?
The book demonstrates dozens of cognitive biases — anchoring, availability, overconfidence. Which of these do you find most disturbing in your own thinking?
Kahneman is a Nobel laureate who has spent decades studying human decision-making. Does his authority make the book more credible — or does it risk making you accept claims you should examine more critically?
The research on which the book is based has faced a replication crisis in psychology. How does this context affect your reading — and does it undermine the book's main arguments?
Thinking, Fast and Slow is a book about why we make poor decisions. Has reading it changed how you think — and what does the fact that it probably hasn't says about the limits of self-knowledge?
