Michael Lewis's account of the Kahneman-Tversky collaboration works as intellectual biography and as a second path through the research for readers who find academic writing slow. The friendship and its eventual fracture clarifies how two very different minds produced work that neither could have done alone.
Kahneman's synthesis of behavioral economics is the cognitive science underpinning every negotiation tactic. Anchoring, loss aversion, framing effects, and the planning fallacy — understanding why these biases operate, not just that they exist, makes you harder to exploit and more honest about your own irrationality.
