Robin Hanson

American economist at George Mason University, best known for The Elephant in the Brain: Hidden Motives in Everyday Life (2018, with Kevin Simler) and The Age of Em: Work, Love, and Life when Robots Rule the Earth (2016).

Hanson trained in physics before moving through the philosophy of science (University of Chicago) into economics. He worked at NASA and in AI research before completing his PhD at Caltech. That path across hard science, philosophy, and social science gave him an outsider’s eye: he noticed gaps between what social scientists write on the chalkboard and how people actually behave, and spent his career trying to explain them. His central contribution is the application of signalling theory — the economic idea that costly or hard-to-fake actions communicate hidden information — to domains where it had rarely been applied: medicine, education, charity, art, politics, and conversation. His claim is not that people are consciously deceptive but that self-deception is a feature, not a bug: we are built to pursue hidden motives (showing off, signalling loyalty) while sincerely believing our stated ones (learning, health, generosity).

Core positions

Human behaviour is driven overwhelmingly by hidden social motives. In a rich society, Hanson puts the signalling share of voluntary behaviour at ‘well over 90 percent’ — not because signalling is the only thing happening but because it is the main thing people refuse to acknowledge, and that refusal distorts our institutions. Medicine is not mainly about health; education is not mainly about learning; charity is not mainly about helping. The useful corrective is not moral condemnation — the cynic’s whiny voice, he notes, is itself a low-status signal — but institutional redesign. His preferred institution is the prediction market: a mechanism that aggregates dispersed information into a price, making it hard to sustain the polite fictions on which most organisations depend. His proposal for governance, futarchy, applies the same logic at the national scale: vote on values, bet on beliefs, and let markets select policy.
