Daniel Kahneman
Daniel Kahneman (1934 to 2024) was a psychologist who shared the 2002 Nobel Memorial Prize in Economic Sciences for work on judgment and decision making under uncertainty. With Amos Tversky he founded the study of heuristics and biases and developed prospect theory, and in 2011 he summarised a lifetime of research in Thinking, Fast and Slow.
