Remembering Daniel Kahneman—and why so many in the startup community admired him.

This week, the startup and academic worlds mourn the loss of Daniel Kahneman, the pioneering psychologist and Nobel laureate behind the groundbreaking book Thinking, Fast & Slow. Kahneman’s work, in partnership with Amos Tversky, challenged the notion of humans as rational decision-makers, laying the foundations for behavioral economics. This shift not only spurred a new economic theory, known as Prospect Theory, but also influenced countless entrepreneurs and business leaders to reevaluate decision-making processes.
