Terence Tao IQ — estimated score & cognitive profile

Terence Tao's IQ is estimated at 225. This is a widely-cited estimate based on Terence Tao's body of work and historical accounts — not a verified, administered psychometric test score. An IQ of 225 would place a person in the top 0.001% of the population (roughly 1 in 25,446,113,429,661,260).

Important note: Most famous-person IQ figures are estimates, retroactive assessments, or based on childhood tests not directly comparable to adult standardised IQ. We present these as historically reported estimates — not verified psychometric measurements.

Terence Tao is often cited as the world's greatest living mathematician. He received a score of 760 on the SAT Math section at age 8 (before any preparation), placing him in the 99.97th percentile. His IQ has been estimated at 220-230. He won the Fields Medal in 2006 and has solved problems across many mathematical fields.

What IQ 225 means

→Pause. Find out YOUR IQ before you keep reading.

An IQ of 225 — if accurate — would place Terence Tao in the Profoundly gifted range, scoring higher than an estimated 99.99%+ of the adult population. Scores above 145 occur in roughly 1 in 1,000 people; scores at 225 are far rarer (about 1 in 25,446,113,429,661,260).

The most instructive case here is Richard Feynman, who reportedly scored 125 on his high-school IQ test — not exceptional — and went on to win the Nobel Prize in Physics. As Feynman himself noted, the test measures a specific kind of reasoning, not the full spectrum of ability required to make world-changing scientific contributions.

Frequently asked about Terence Tao's IQ

What was Terence Tao's IQ?

Terence Tao's IQ is estimated at 225, though this is a retrospective estimate based on their work and accomplishments rather than a verified test result.

Did Terence Tao actually take an IQ test?

There is no reliable public record of Terence Tao taking a standardized adult IQ test with a verified score. The figure of 225 is an estimate that circulates in popular media.

How rare is an IQ of 225?

An IQ of 225 occurs in roughly 1 in 25,446,113,429,661,260 people — the top 0.001% of the population on a standard deviation IQ scale (SD 15).

Is Terence Tao's IQ score reliable?

Treat it as suggestive, not definitive. Famous-person IQ figures are often extrapolated from achievements, childhood ratio-IQ tests, or unsourced media claims, none of which are directly comparable to a modern administered adult IQ test.
