Famous people — IQ estimates

Estimated or reported IQ scores for notable scientists, entrepreneurs, athletes, and thinkers. Most are estimates or retroactive assessments — we explain the methodology and limitations for each.

A note on famous IQ claims

IQ estimates for famous people circulate widely online but are often unreliable. Historical figures like Einstein and Newton never took an IQ test — their estimated scores are extrapolated from their scientific contributions, not measured. Very high scores (above 160) are particularly difficult to verify as standardised tests lose precision at the extremes of the distribution. We present these as historically reported estimates, clearly labelled as such.
