Behavioral Economics

Daniel Kahneman

1934–2024 · Behavioral Economics


The Cartographer of Human Error

Kahneman is for the person who wants to understand why smart people — including you — make predictably terrible decisions. You probably already sense that your confidence in your own judgment is part of the problem, not the solution. Kahneman spent fifty years with Amos Tversky cataloguing the systematic errors wired into human cognition, then won a Nobel Prize for proving that rationality is not the default mode of the human mind. He doesn't make you smarter. He makes you appropriately suspicious of your own certainty — which turns out to be the same thing.

Where to Start Reading

Thinking, Fast and Slow

The essential Kahneman. System 1 (fast, intuitive, wrong in specific ways) versus System 2 (slow, deliberate, lazy). Dense at 500 pages but every chapter stands alone — you can dip in anywhere. One of the most cited nonfiction books of the 21st century.

Noise: A Flaw in Human Judgment

Co-written with Cass Sunstein and Olivier Sibony. Where Thinking, Fast and Slow is about bias (predictable error), Noise is about variability (random error). Shorter, more focused, and genuinely unsettling — it shows that expert judgment is far less consistent than anyone assumes.
