Amos Tversky
Amos Tversky (1937 to 1996) was a cognitive and mathematical psychologist whose work with Daniel Kahneman changed how we understand judgment and choice. Together they published studies on heuristics and biases in the 1970s, including the 1974 paper on anchoring, and prospect theory in 1979.
