Celebs With High IQ: Who Has a Published Score and Who Only Has a Rumor?
Very few celebrities have a published IQ score: of 366 profiles, 23 have a test or test-based score on record. 135 of 242 circulating figures are 150 or higher, and 6 have a test behind them. Which famous numbers hold up, and which are rumors.

Very few celebrities have a published IQ score. Of the 366 profiles on IQ Metrics, only 23 have a test or test-based score on record. The rest depend on school or academic records, achievements, or a number that only circulates online. That is the honest answer to “celebs with high IQ”.
Below: how the 366 sort by evidence, which famous numbers hold up, which do not, and how to read a claim. The finding most lists skip: 135 of the 242 non-fictional profiles that carry a circulating figure circulate at 150 or higher, and only 6 of those 135 have any test behind them.

Key takeaways
- Counts, 5 November 2026: 23 profiles have a test or test-based score on record (7.1% of the 323 real people), 213 rest on a documented record, 87 on achievement-based estimates and 43 are fictional.
- Rumor outruns evidence: 135 of 242 circulating figures are 150 or higher, and 6 of the 135 have a test score behind them.
- Documented numbers are modest: Feynman 125 (reported), John F. Kennedy 119 (school record), Kim Peek 87 (1988 testing, flagged as not valid).
- Hoaxes spread: the 2001 “Lovenstein Institute” list gave Kennedy 174. No such institute existed.
- Confirmed is not scored: Geena Davis has confirmed her own Mensa membership, but no score has been published by her or by Mensa.
Which celebs with high IQ have a published score?
Only a few have a documented test score, and the best-documented ones are not the highest numbers on the lists. The famous high figures mostly have no test behind them.
We sort every profile by the best evidence we found. A test-anchored profile has a reported score from a test, such as a school test, an SAT or a Mensa qualification. A record profile has no score, but a documented academic or performance record, such as a doctorate or a published chess rating. An achievement-based profile rests on a historian’s estimate from a person’s work, like the 1926 Cox study. Our celebrity IQ profiles show the tier on every page.
| Evidence behind the profile | Profiles | Share of the 323 real people |
|---|---|---|
| A test or test-based score on record | 23 | 7.1% |
| A documented academic, performance or clinical record, no score | 213 | 65.9% |
| An estimate from achievements (Cox 1926 and similar) | 87 | 26.9% |
| Fictional characters (nothing to measure) | 43 | not counted |
The three shares add to about 100% of the 323 real people. Fictional characters are in the 366 but not in that base. For historical figures the gap is widest, because no test existed in their lifetime. Our study of the IQ of historical geniuses covers that method.
What are the famous people with high IQ that have a source?
The sourced cases are real but more modest than the rumors, and they come with caveats. These four are deceased and each has a profile that names its source.
- Richard Feynman, reported 125. Gleick’s 1992 biography gives 125 and the original test record has never surfaced. His documented record is far stronger: Putnam Fellow in 1939 and the 1965 Nobel Prize in Physics. See the Feynman profile.
- John F. Kennedy, 119. The figure comes from his Choate school record. The 174 that circulates comes from a fabricated 2001 study. See the Kennedy profile.
- Kim Peek, 87. It traces to psychological testing in 1988 reported by Treffert and Christensen in Scientific American, whose report said the IQ classification is not a valid description of his ability. See the Kim Peek profile.
- Muhammad Ali, 16th to 18th percentile. It is a 1964 Armed Forces qualification test, not an IQ test, and the exact conversion is disputed: 78 in press tradition, 83 in FBI files. See the Muhammad Ali profile.
Who are the highest IQ celebrities, and who only has a rumor?
Most of the highest numbers belong to the rumor tier. Across 242 non-fictional profiles that carry a circulating figure, 135 circulate at 150 or higher, and 6 of those have any test behind them.
Look at what the figure is. It is the number that circulates on lists and social posts, not a score someone published. Of the 102 that circulate at 160 or higher, again only 6 have a test behind them. A list that puts famous people in order of IQ is therefore ranking rumors. For what a 150 or 160 would actually mean on the bell curve, see our guides to an IQ of 150 and an IQ of 160.
Our guide to the highest IQ ever recorded covers the few cases with a real record, and what the tests could report.
Do famous people with high IQ include Hollywood stars?
A few, but the Hollywood record is mostly claims. Of the 42 actors and filmmakers we profile, 3 have a test or test-based score, and 37 rest on a documented record.
One example is Geena Davis. She confirmed her Mensa membership on the record, and no score has been published by her or by Mensa. The “140” that circulates traces to a tabloid whose text never states it. See the Geena Davis profile. Our actors and filmmakers and musicians categories list the rest, and the blog post on Hollywood celebrities and their hidden talent covers the talents.
How does the evidence break down by category?
Athletes have the most test-based scores, and historical figures have the fewest records. The table shows all eight real-people categories.
| Category | Test on record | Documented record | Estimated from achievements | Total |
|---|---|---|---|---|
| Business and tech leaders | 1 | 29 | 10 | 40 |
| Scientists and physicists | 5 | 31 | 6 | 42 |
| Actors and filmmakers | 3 | 37 | 2 | 42 |
| Musicians | 1 | 29 | 7 | 37 |
| Athletes | 7 | 30 | 5 | 42 |
| Writers and thinkers | 1 | 22 | 14 | 37 |
| Political figures | 2 | 28 | 12 | 42 |
| Historical figures | 3 | 7 | 31 | 41 |
Athletes lead because sport leaves measurable records: 14 of the 42 athlete profiles rest on domain performance, mostly published chess ratings, and others on reported Wonderlic or SAT results. Historical figures sit at the other end, with 31 of 41 estimated from achievements.
Where would your own score land?
Take the IIF-certified assessment and get your score with the scale it was measured on, the percentile it corresponds to and the confidence range around it — the three figures most online tests leave out.

Because most lists copy each other and none cite a test. Plato is a clear case: two numbers circulate for him, 146 and 180, a gap of 34 points, and neither comes with a method.
Plato died about 2,400 years ago, and intelligence testing began in 1905, so no test result could exist. The 180 comes from a modern ranking site and the 146 from an informal online survey. Our profile of Plato sets out both and the achievement-based range we can defend instead. The pattern repeats across the dead: a historian can estimate from a person’s work, as Cox did in 1926, but an estimate is not a measurement.
How should you read a celebrity IQ claim?
Ask four things: which test, which scale, who published it and when. A number without all four is a rumor.
Even a real score needs a scale. A 130 is the 97.7th percentile on a scale with a standard deviation of 15, as our IQ bell curve shows, and a different place on other scales. A single score also carries a range of several points, as our guide to an IQ of 112 shows with a worked example. If you want a number for yourself, take the IQ test and read it against a percentile.

- What are the highest IQ celebrities? The highest numbers on lists are mostly unsourced: 6 of 135 figures of 150 or higher have a test behind them.
- Is John F. Kennedy’s IQ 174? No. That came from a fabricated 2001 list. His school record gives 119.
- Has Geena Davis published an IQ score? No. She confirmed Mensa membership, but no score is on record.
- Where can I see each person’s evidence? Every profile in the celebrity IQ section lists its sources and the tier of evidence.
The bottom line
Celebs with high IQ are a short list of people with documented tests and a long list of people with rumors. Of 366 profiles, 23 have a test or test-based score on record, and the best-sourced numbers are modest. Treat any list that ranks famous people by IQ as a list of claims, and check the source behind each one.

Scores & ScalesHighest IQ Ever Recorded
The highest IQ ever recorded is usually given as Marilyn vos Savant's 228 or William James Sidis's claimed 250 to 300 - neither from a test in use today. Where the famous numbers actually come from, and what a modern test can really report.
Scores & ScalesWhat an IQ of 150 Means
An IQ of 150 is about 1 person in 2,331 on a standard deviation 15 scale, the 99.96th percentile. See how rare it really is, what "genius" cutoffs actually mean, and why scores this high need a real test to trust.
Scores & ScalesWhat an IQ of 135 Means
An IQ of 135 is the 99th percentile: one person in 102 on the Wechsler scale, but only 1 in 14 on the Cattell scale. Rarity of every score from 130 to 139, the cut-off Terman really used, how precise a 135 is, and what it predicts.
