Daniel Kahneman, an Israeli-American cognitive psychologist who won the Nobel Prize in Economics in 2002, passed away last night. Kahneman was a pioneer in the study of decision-making and behavioral economics.

The Solidite, aka Doreen Hartman, wrote a farewell post from Mahanman with the things she learned from him. "The right lesson to be learned from surprises is that the world surprises," he said. "High self-confidence indicates that someone has woven a coherent story in their mind," he added.
