The Undoing Project: A Friendship that Changed the World

I hadn’t actually thought much about the psychological aspects of the Moneyball story… All of these biases that the Oakland front office talked about I’d found interesting but I hadn’t really pushed further and asked: where do the biases come from? Why do people have them? I’d set out to tell a story about the way markets worked, or failed to work, especially when they were valuing people. But buried somewhere inside it was another story, one that I’d left unexplored and untold, about the way the human mind worked, or failed to work when it was forming judgements and making decisions.

From Michael Lewis, the No.1 bestselling author of Moneyball, The Big Short and Flash Boys, comes an extraordinary story of two men whose ideas changed the world.

Daniel Kahneman and Amos Tversky met in war-torn 1960s Israel. Both were gifted young psychology professors: Kahneman a rootless son of holocaust survivors who saw the world as a problem to be solved; Tversky a voluble, instinctual blur of energy.

In this breath-taking new book, Michael Lewis tells the extraordinary story of a relationship that became a shared mind: one which created the field of behavioural economics, revolutionising everything from Big Data to medicine, from how we are governed to how we spend, from high finance to football.

Kahneman and Tversky, shows Michael Lewis, helped shape the world in which we now live and may well have changed, for good, humankind's view of its own mind.
