Daniel Kahneman is an Israeli-American author, psychologist, and economist celebrated for his significant contributions to the fields of hedonic psychology, judgment and decision-making psychology, and behavioral economics. His work has notably challenged longstanding assumptions of human rationality prevalent within modern economic theory.

Together with Amos Tversky and others, Kahneman laid the foundations for understanding common human errors stemming from heuristics and biases and formulated prospect theory. In recognition of his pioneering integration of psychological research into economics, particularly regarding human judgment and decision-making under uncertainty, Kahneman was awarded the 2002 Nobel Memorial Prize in Economic Sciences, alongside Vernon L. Smith.

Kahneman's influence extends beyond academia, as evidenced by his inclusion in Foreign Policy magazine's list of top global thinkers in 2011. His bestselling book, Thinking, Fast and Slow, encapsulates much of his research and continues to impact readers worldwide. He is also heralded by The Economist as one of the most influential economists globally. Kahneman holds the title of professor emeritus at the Princeton University's School of Public and International Affairs and actively contributes to the field as a founding partner of the TGG Group, a consultancy firm.

He was married to the esteemed cognitive psychologist and Royal Society Fellow, Anne Treisman, until her death in 2018.
