What is Sylvester Stallone’s IQ?
He wrote Rocky in about three days and was Oscar-nominated as both its screenwriter and its star.
Sylvester Stallone’s IQ has never been published: no test result exists as of November 2026, and the 160 that circulates online names no test, examiner or date. His documented record — a produced screenplay for Rocky, written in about three days, that drew Oscar nominations for both its writing and its lead performance — supports an estimated IQ of 120–135 on the standard scale with a mean of 100.
Sylvester Stallone’s estimated IQ
- Completed a first draft of Rocky within about three days of watching Muhammad Ali fight Chuck Wepner on March 24, 1975. The finished film (1976) drew ten Academy Award nominations, including Best Actor and Best Original Screenplay for Stallone himself.
- Attended several schools as a teenager, among them Notre Dame Academy and Abraham Lincoln High School in Philadelphia and Charlotte Hall Military Academy in Maryland, and Devereux, which a 2026 New York Times interviewer described as a school “for kids that needed discipline.”
- Studied at the American College of Switzerland (1965–1967) and then drama at the University of Miami (1967–1969) without finishing; Miami conferred a Bachelor of Fine Arts in 1998, decades after he left as a student.
- Wrote and directed Rocky II (1979) and Rocky III (1982), and is credited as a co-writer of First Blood (1982), adapted from David Morrell’s 1972 novel, and of the Rambo films that followed, sustaining authorship across two franchises from 1976 to 2018.
- Earned a third Academy Award nomination (Best Supporting Actor) and a Golden Globe win for Creed (2015), and shares the screenplay credit for Creed II (2018) with Juel Taylor.
The strongest part of the record is what Stallone built, not what school made of him: his own schooling is documented as uneven, not strong. The range rests on a produced screenplay, sustained writing and directing credits and industry recognition rather than grades, a degree completed on schedule or a test. Those markers show skilled, sustained work in writing and filmmaking. They cannot separate IQ from effort, training and luck, which is why the range is 15 points wide and nothing on this page is a measured score.

What an IQ of 120–135 actually means
Set the claim aside for a moment. If someone genuinely scored in this range, here is what that would represent.
Average is 100 by construction, and about two-thirds of people fall between 85 and 115. Take the test to place your own score on this scale.
| Score range | Classification | Share of people | What it indicates |
|---|---|---|---|
| 85 – 114 | Average | ~68% | The range most people fall into. |
| 115 – 129 | Above average | ~13.6% | Roughly one person in seven. |
| 130 – 144 | Gifted | ~2% | The threshold most high-IQ societies use. |
| Above 144 | Highly gifted | ~0.1% | Figures above this range are extrapolated from the curve rather than measured. |
Percentages are approximate and describe a normal distribution. The same number means different things on tests with different standard deviations.
Thirty questions gives you a measured position on this exact scale — your score, your percentile and the ability breakdown behind it.

Sylvester Stallone was born on July 6, 1946, in New York City. As a teenager he attended several schools, among them Notre Dame Academy and Abraham Lincoln High School in Philadelphia and Charlotte Hall Military Academy in Maryland, and Devereux, a school that a New York Times interviewer described in 2026 as one “for kids that needed discipline.”
From September 1965 to June 1967 he studied at the American College of Switzerland, then majored in drama at the University of Miami from 1967 to 1969 without graduating. Decades later the University of Miami granted him a Bachelor of Fine Arts in 1998, after he asked that his acting and life experience count toward the credits he still needed.
Before Rocky he took small film roles, including The Lords of Flatbush (1974), on which he is credited as a writer, and Death Race 2000 (1975). On March 24, 1975, he watched Muhammad Ali fight Chuck Wepner, and within about three days he had finished a first draft of a boxing screenplay. He refused to let the film be made without him in the lead, and United Artists agreed.
Rocky premiered in New York on November 20, 1976, and opened across the United States on December 3, 1976. Made for about a million dollars, it grossed about 225 million dollars worldwide. At the 49th Academy Awards in 1977 it received ten nominations, including Best Actor and Best Original Screenplay for Stallone, and won three: Best Picture, Best Director and Best Film Editing. In 2006 the Writers Guild of America selected the screenplay as the 78th best of all time.
He wrote, directed and starred in Rocky II (1979) and Rocky III (1982). First Blood (1982), based on David Morrell’s 1972 novel, credits Michael Kozoll, William Sackheim and Stallone as writers and launched the Rambo series, five films between 1982 and 2019 in which he played John Rambo.
Creed (2015) brought a third Academy Award nomination, for Best Supporting Actor, and a Golden Globe win in the same category. He shares the screenplay credit for Creed II (2018) with Juel Taylor. Wikipedia lists a Kennedy Center Honors in 2025 among his recognitions. His memoir, The Steps, was published in late September 2026, after he turned 80 that July.

Where the 160 figure came from
Following a claim back to its first appearance is the part almost nobody does — and it is what most people are actually asking.
Where does the Sylvester Stallone IQ 160 figure come from? From celebrity-IQ pages that print or discuss it without a test. One IQ-information site states that “no instrument, no date, no examiner and no norm sample appears in any version of the claim.”
A second one calls the number “a complete fabrication.” sociosite.net prints it as merely “claimed,” citing unnamed “multiple sources,” and celebrityiqs.com states “IQ: 160” as a bare fact before a footer disclaimer that the site’s scores are “not guaranteed” and “for entertainment purposes only.” No Sylvester Stallone IQ test result stands behind any of them: no test name, no examiner, no date (see where celebrity IQ numbers come from). Stallone’s Wikipedia biography gives no IQ figure either.
The Mensa half of the search pair has even less behind it. Wikipedia’s biography of Stallone never mentions Mensa, and Wikipedia’s category of notable Mensa members, about 212 entries when it was last edited in April 2025, does not list him.
American Mensa’s own published criterion is a score in the top 2 percent on a supervised, standardized test (see Mensa’s score requirements), a specific, checkable bar that no source places Stallone near, high or low. As of November 2026, no source we found records an application, a membership or a claim of eligibility.
Is Sylvester Stallone smart in real life? His published record shows a productive, award-nominated writer, and his own words show how he has been perceived. In a New York Times interview about his memoir The Steps, he said he had been dismissed with lines like “You’re not that smart.
You’re an action guy,” and that being called stupid “would turn me into a maniac to prove I’m not stupid.” Neither remark comes with a test score; they describe reputation and drive. Whether that amounts to genius is a separate question: what a genius-level IQ means explains the usual definition, and no source applies it to Stallone.
How smart is Sylvester Stallone? The record supports an estimated IQ of 120–135, inferred from what he built rather than from a test. After watching the Ali–Wepner fight he wrote the first draft of Rocky in about three days and refused to let the film be made without him in the lead.
The finished film was nominated for ten Academy Awards, including Best Actor and Best Original Screenplay for Stallone, and won three, among them Best Picture. That range sits level with Arnold Schwarzenegger’s 120–135, a fellow 1980s action star whose estimate also rests on built, not tested, achievement, and with Matt Damon’s 120–135: Damon and Ben Affleck wrote and starred in Good Will Hunting (1997) and won the Best Original Screenplay Oscar.
Their agent knew of only one precedent for a film written by and starring an unknown actor, Rocky. It sits below Dolph Lundgren’s 140–155; Lundgren played Ivan Drago opposite Stallone in Rocky IV (1985), and his estimate rests on chemical-engineering study that Stallone’s schooling does not parallel.
On a scale with a mean of 100 and a standard deviation of 15, the circulating 160 would be four standard deviations above average, rarer than about one person in 30,000. The IQ percentile calculator shows where any score sits, and more actors appear under other actors we have checked.
How we read a number →States the membership bar: “Score in the top 2%, and congratulations — you qualify for American Mensa,” reached through a supervised, standardized test or a qualifying prior score. No mention of Stallone; used to check the “mensa” search pairing against Mensa’s own published criterion.
Orientation and cross-checks: birth date and place, the schools attended, the American College of Switzerland and University of Miami years, the 1998 Bachelor of Fine Arts, the Rocky writing, release, budget, box-office and Academy Award facts, the First Blood and Creed II writing credits, the Golden Globe and 2025 Kennedy Center Honors, and Good Will Hunting’s Original Screenplay Oscar. The Category: Mensans page, about 212 entries and last edited in April 2025, does not list Stallone. None of these pages states an IQ figure for him.
In his own words: asked about Devereux, which the interviewer describes as a school “for kids that needed discipline,” Stallone answers with the name; he says he had been “reduced to a lump of meat” by lines like “You’re not that smart. You’re an action guy,” and that being called stupid “would turn me into a maniac to prove I’m not stupid.” No test score is given for any of it.
Confirms that Stallone turned 80 in July 2026 and that his memoir was published on a Tuesday, after a September 28, 2026 event at the 92nd Street Y in New York. Contains no IQ figure in the passages used.
States the 160 is “unsupported: no instrument, no date, no examiner and no norm sample appears in any version of the claim,” and that “no membership record was located” for Mensa.
States that “despite frequent online claims assigning him a staggering score of 160, no credible record exists of him ever sitting for a professionally administered intelligence test,” calling the number “a complete fabrication.” Names no test, examiner or date.
sociosite.net states the IQ “is claimed to be 160 … according to multiple sources” without naming any of them. celebrityiqs.com lists “IQ: 160” with a footer disclaimer that scores on the site are “not guaranteed” and are “for entertainment purposes only.” Neither names a test, examiner or date.
None from Stallone, a school or a psychologist. Looked for in Stallone’s Wikipedia biography and the Wikipedia category of notable Mensa members; neither contains a score, a test name or a Mensa claim tied to Stallone, and the four aggregator pages above name no test.
The sources behind our estimate
The figures that circulate for Sylvester Stallone, what we were able to confirm, and where the two diverge.
Searchers pair his name with “iq 160” and “mensa.” The number is 160, printed as a bare or “claimed” fact by sociosite.net and celebrityiqs.com and examined, as unsupported, by two IQ-information sites.
No Sylvester Stallone IQ test result has been published, and none of the four pages that discuss the 160 names a test, an examiner or a date. One IQ-information site states that “no instrument, no date, no examiner and no norm sample appears in any version of the claim,” and adds that no Mensa membership record was located. A second one calls the number “a complete fabrication.” sociosite.net hedges with “claimed to be,” citing unnamed “multiple sources.” celebrityiqs.com prints “IQ: 160” as a bare fact, then adds a footer disclaimer that its scores are “not guaranteed” and “for entertainment purposes only.” Wikipedia’s biography of Stallone gives no IQ figure and does not mention Mensa, and Wikipedia’s category of notable Mensa members does not list him. What can be checked is the record: named schools, a drama degree that arrived decades late, and a produced, Oscar-nominated screenplay.
The circulating 160 sits 25 points above the top of the 120–135 range the record supports, and four standard deviations above the mean of 100 on a 15-point scale. The documented record — schooling and screenwriting, not scores — points lower than the number in circulation, and the Mensa half of the search pair has no documented basis at all.

Sylvester Stallone — frequently asked
What is Sylvester Stallone’s IQ?
No IQ test result has been published for Sylvester “Sly” Stallone, so his IQ is unknown. The 160 that circulates online comes from celebrity-IQ pages that name no test, examiner or date. IQ Metrics estimates 120–135 from his documented record of schooling, screenwriting and directing, and treats it as an estimate, not a score.
What is Sylvester Stallone’s IQ level?
An estimated 120–135, which on a scale with a mean of 100 and a standard deviation of 15 falls at about the 91st to the 99th percentile. The estimate is inferred from his achievements, since no score has been published, so it describes a likely band rather than a measurement.
Is Sylvester Stallone’s IQ 160?
There is no evidence that it is. The 160 (also searched as “qi 160”) appears on celebrity-IQ pages that name no test, examiner or date. On a scale with a mean of 100 and a standard deviation of 15, a 160 would be four standard deviations above average, roughly 1 in 30,000, well above the 135 top of IQ Metrics’ range.
Does Sylvester Stallone have a high IQ?
Probably above average, but no test shows it. IQ Metrics’ estimate of 120–135 straddles 130, which marks roughly the top 2 percent on a 15-point scale, so it is neither clearly ordinary nor clearly exceptional. It rests on what he wrote and directed, not on a measured result.
Is Sylvester Stallone smart?
His record says so in the fields he chose: he wrote a first draft of Rocky in about three days and was nominated for Academy Awards for both writing and acting in it. In a New York Times interview about his memoir The Steps, he recalled being told “You’re not that smart. You’re an action guy.” No test score accompanies either point.
Is Sylvester Stallone intelligent?
Documented evidence points to strong verbal and organizing skill, not to a measured score. Wikipedia lists him as director of eight feature films, from Paradise Alley (1978) to The Expendables (2010), and as a credited writer on films including The Lords of Flatbush (1974), Rocky (1976) and Creed II (2018). An IQ test would measure reasoning, and none has been published.
Is Sylvester Stallone a genius?
No test or source rates him a genius, and IQ Metrics’ estimate of 120–135 does not claim it. His documented achievement is real, though: the Writers Guild of America selected his Rocky screenplay in 2006 as the 78th best screenplay of all time, according to Wikipedia’s article on the film.
Is Sylvester Stallone in Mensa?
No source we found says so. His Wikipedia biography does not mention Mensa, and Wikipedia’s category of notable Mensa members, about 212 entries when last edited in April 2025, does not list him. American Mensa admits people who score in the top 2 percent on a supervised, standardized test; no source gives Stallone such a score.
Did Sylvester Stallone graduate from college?
Not on schedule. He studied at the American College of Switzerland from September 1965 to June 1967 and majored in drama at the University of Miami from 1967 to 1969 without graduating, according to Wikipedia. The University of Miami granted him a Bachelor of Fine Arts in 1998, after he asked that his acting and life experience count toward the missing credits.
How does Sylvester Stallone’s estimated IQ compare with Arnold Schwarzenegger’s?
IQ Metrics places Stallone’s estimated range of 120–135 level with Arnold Schwarzenegger’s 120–135, and with Matt Damon’s and Ben Affleck’s, who won the Best Original Screenplay Oscar for Good Will Hunting (1997). It sits below Dolph Lundgren’s 140–155. All of these are estimates drawn from records, not test scores.
How does my IQ compare with Sylvester Stallone?
You can find out in about fifteen minutes. The IQ Metrics assessment is 30 questions, scored on the same 100-mean scale used throughout this page, so your result and the estimate above are at least expressed in the same units — one measured, one inferred. Once you have a number, the leaderboard shows where it would sit, and how we score and norm it explains the benchmarking.
