Bounded: How Herbert Simon Redefined Intelligence

Herbert Simon won the Nobel Prize in Economics without being primarily an economist. He helped found artificial intelligence while insisting it was really psychology. He wrote more than a thousand papers across six disciplines and changed every field he touched. Most people have never heard his name.

Born in Milwaukee in 1916, Simon spent his career chasing one question: how do humans actually make decisions? The answer he found was radical. Humans don't optimize. They can't. Instead they satisfice — searching for a good enough answer and stopping when they find one. He called this bounded rationality, and it made powerful enemies.

The economics establishment had invested decades in the fiction of the perfectly rational agent. Simon spent thirty years dismantling it with evidence, paper by careful paper, study by patient study. Along the way he built the first computer program to reason rather than calculate, helped launch the field of artificial intelligence, and laid the foundations for everything we now call behavioral economics.

The Nobel came in 1978. The world caught up slowly. It is still catching up.

We live in the attention economy Simon predicted in 1971. The algorithmic systems overwhelming our decision-making exploit the exact cognitive limits he spent his life describing. The AI systems being built into the infrastructure of civilization raise the precise questions he spent sixty years asking.

Bounded is the story of the man behind the ideas — patient, precise, relentless — and why his work has never mattered more.
