Biography
Amos Tversky was a psychologist who thought like a mathematician, and his partnership with Daniel Kahneman produced nothing less than a new map of the human mind. Working in Israel and later at top American universities, they challenged the prevailing model of humans as rational actors. Through elegantly simple experiments, Tversky identified a suite of predictable mental errors—cognitive biases like loss aversion and the anchoring effect—that shape our judgments under uncertainty. This work, known as prospect theory, provided the bedrock for the field of behavioral economics. Tversky's razor-sharp intellect and relentless focus on how people actually think, rather than how they should, transformed psychology, economics, and our fundamental understanding of ourselves.
The Silent Generation
1928–1945
Born between the Depression and the end of WWII. Too young to fight, old enough to remember. They became the conformist middle managers of the 1950s — and the civil rights leaders who quietly dismantled Jim Crow.
Amos was born in 1937, placing them squarely in The Silent Generation. The events that shaped this generation — world wars, depression, and rapid industrialization — shaped the world they entered and the choices available to them.
