The foundational paper on heuristics and biases, including representativeness — the mental shortcut that makes improbable-seeming coincidences feel so meaningful.
Amos Tversky and Daniel Kahneman's 1974 paper in Science launched the heuristics-and-biases program and, with it, the modern understanding of why coincidences feel meaningful. Their account of the representativeness heuristic — judging by resemblance rather than probability — is the direct intellectual ancestor of the skeptical view.
The paper's relevance here is hard to overstate. "What are the odds?" is a question the mind answers with a shortcut, not with arithmetic, and the shortcut is systematically wrong. Kahneman would later win a Nobel Prize for this work. For anyone wondering why an improbable-seeming coincidence feels like proof, this is the place to start.
The meaning
The paper maps the machinery of intuition with such precision that even believers use it to describe what the mind is doing.
The skeptic
It is the intellectual root of the entire skeptical account: the brain judges by resemblance, not by probability.
About the research
The psychologists whose work on judgment under uncertainty earned a Nobel Prize.
Key takeaways
- The 1974 Science paper that launched the heuristics-and-biases program.
- Explains representativeness, the shortcut behind "what are the odds?"
- Won a Nobel Prize for its authors; central to understanding coincidence.
