The psychologist Daniel Kahneman — a Nobel laureate and the author of “Thinking, Fast and Slow” — recently died at age 90. Along with his collaborator Amos Tversky, he changed how we all think about decision-making. The journalist Michael Lewis told the Kahneman-Tversky story in a 2016 book called "The Undoing Project." In this episode, Lewis explains why they had such a profound influence.
