What is Matt Damon’s IQ?
Twelve credits short of Harvard — and an Oscar for a character’s genius, not his own.
Matt Damon enrolled at Harvard in 1988 and left in 1992, an English concentration twelve credits short of a bachelor’s degree, the same year he carried the early pages of what became Good Will Hunting to Los Angeles. The 160 that circulates for his IQ traces to no test; the clearest documented source for it is a listicle that names the fictional genius he wrote and played as its own evidence.
Matt Damon’s estimated IQ
- Enrolled at Harvard in 1988 as an English concentrator, class of 1992, living in Lowell House, and left in his final semester — twelve credits short of a Bachelor of Arts — as film work, including a supporting role in Geronimo: An American Legend, pulled him away from campus.
- Wrote an early draft of what became Good Will Hunting as the final project for a playwriting class taught by Anthony Kubiak, turning in roughly forty pages in place of the assigned one-act play; spent the next several years expanding it with childhood friend Ben Affleck, finishing a full screenplay in 1994.
- Shared the Academy Award and Golden Globe for Best Original Screenplay with Affleck for Good Will Hunting (1997), one of four Oscar nominations across his acting and writing — also Best Actor for Good Will Hunting and The Martian, and Best Supporting Actor for Invictus.
- Co-founded the H2O Africa Foundation in 2006, merged it with engineer Gary White’s WaterPartners to form Water.org in 2009, and co-founded the impact-investing fund WaterEquity with White in 2017; the two organizations report having reached more than 60 million people with access to safe water or sanitation.
No IQ test result for Damon has ever been published, and he left Harvard without finishing his degree, so this range leans on admission to and near-completion of a highly selective university, one competitively judged screenwriting award, and a sustained, independently reported nonprofit record — real and checkable, but still an inference built from achievement rather than a score. Screenwriting success and nonprofit fundraising reward voice, timing, and partnership as much as raw cognitive ability.

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.

Matthew Paige Damon was born on 8 October 1970 in Cambridge, Massachusetts, to Kent Damon, a stockbroker, and Nancy Carlsson-Paige, a professor of early childhood education at Lesley University. He attended Cambridge Rindge and Latin School, where he grew up around the corner from Ben Affleck; their mothers, professional acquaintances, introduced the two boys as children, and they have written and acted together ever since. Damon enrolled at Harvard in 1988, a member of the class of 1992 living in Lowell House and concentrating in English, taking on film roles — including a supporting part in Geronimo: An American Legend — around his coursework.
For a playwriting class taught by Anthony Kubiak, Damon turned a one-act assignment into roughly forty pages of a longer story, telling his professor it might be the first act of something bigger. He left Harvard in 1992, twelve credits short of his degree, and carried the pages to Los Angeles, where Affleck helped expand them into a full screenplay; the two finished a version in 1994 and spent several years shopping it before Miramax produced it as Good Will Hunting, directed by Gus Van Sant and released in December 1997. Damon and Affleck won the Academy Award and Golden Globe for Best Original Screenplay; Damon was also nominated for Best Actor, and Robin Williams won Best Supporting Actor. Damon returned to Harvard in April 2013 to receive the Harvard Arts Medal, an annual award for a Harvard-affiliated artist that is separate from a degree — he still has not completed one.
He went on to lead the Bourne franchise, the Ocean’s Eleven trilogy and, in 2023, Christopher Nolan’s Oppenheimer, among dozens of other films, picking up further Academy Award nominations for Invictus (2009) and The Martian (2015) and a second Golden Globe, for Best Actor, for the latter. Outside acting, he founded the H2O Africa Foundation in 2006, which merged with engineer Gary White’s WaterPartners in 2009 to form Water.org, and co-founded the impact-investing fund WaterEquity with White in 2017; the two organizations report having reached more than 60 million people with access to safe water or sanitation.

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.
Search “Matt Damon IQ” and the 160 that comes back rests on an unusually specific, checkable confusion rather than just a copied guess. brainmanager.io states it outright: “Matt Damon wasn’t just acting when he played a math genius in Good Will Hunting — he’s widely considered a real-life intellectual,” and cites his Harvard enrollment and the Oscar-winning screenplay as further evidence. That is Will Hunting’s intelligence, on loan to the man who wrote and played him. It is worth noting that the film itself never assigns its genius a number either — Will is “off the charts” in dialogue and behavior, not a stated score — so even the fictional source of the association carries no figure to inherit.
The rest of the ecosystem is the more familiar kind of unsourced repetition. celebrityiqs.com and celebsiq.com post 160 with no citation, one under a standing disclaimer that its scores are “not guaranteed” and offered “for entertainment purposes only.” check-iq.org attributes its 160 to “Harper’s Bazaar” — no such article with a stated methodology could be located, only further copies of the same number — while its own lower-confidence 143 is credited to MSN with the same absence of a traceable original. sociosite.net adds an unsupported comparison to Quentin Tarantino and Stephen Hawking, the same rhetorical move it uses elsewhere on this site to prop up Dexter Holland’s figure. A separate, near-identically worded claim across several of these sites adds that Damon was invited to join Mensa and declined; no date, event, or quotation from Damon supports it anywhere we could find.
Damon’s Harvard record makes its most instructive comparison on this site not to a hoax but to Natalie Portman, the only other Harvard name in this category — she enrolled in 1999 and finished her degree, psychology, plus two published papers, while working as an actor throughout. His closer parallel is Ashton Kutcher: both left a selective or semi-selective program without a diploma and built something independently documented instead — a $250 million venture portfolio for Kutcher, a produced and competitively awarded screenplay plus a nonprofit reaching tens of millions of people for Damon. Neither substitution is a test score. Both are considerably more specific than a number with nothing under it.

The sources behind our estimate
The figures that circulate for Matt Damon, what we were able to confirm, and where the two diverge.
160 is the figure that recurs across celebrity-IQ listicles (celebrityiqs.com, celebsiq.com, sociosite.net, among others); check-iq.org lists a lower-confidence 143 alongside it, credited to MSN.
We found no published IQ test result for Matt Damon. celebrityiqs.com and celebsiq.com post 160 with no source at all, one under a standing disclaimer that its figures are “not guaranteed” and offered “for entertainment purposes only.” check-iq.org credits the same 160 to “Harper’s Bazaar,” but no Harper’s Bazaar article stating a methodology could be located anywhere — only further copies of the same number — while its own lower-confidence 143 is credited to MSN with the same absence of a traceable original. sociosite.net adds an unsupported comparison to Quentin Tarantino and Stephen Hawking. Most directly, brainmanager.io states: “Matt Damon wasn’t just acting when he played a math genius in Good Will Hunting — he’s widely considered a real-life intellectual,” citing the role itself, alongside his Harvard enrollment, as evidence. That reasoning credits Damon with a fictional character’s intelligence. A separate, near-identically worded claim across several of these sites adds that Damon was invited to join Mensa and declined — no date, event, or quotation from Damon supports it anywhere we could find.
The credentialed range and the popular figure sit well apart — and for once the gap has a clean explanation: a listicle naming a fictional character’s genius as evidence for the real person who wrote him.

Matt Damon — frequently asked
What is Matt Damon’s IQ?
No test result has ever been published. The 160 that circulates on celebrity-IQ listicles traces to no cited study — check-iq.org attributes it to “Harper’s Bazaar,” though no such article could be located. What’s documented instead is a Harvard record left twelve credits short of a degree and an Academy Award for co-writing Good Will Hunting.
Did Matt Damon graduate from Harvard?
No. He enrolled in 1988 as an English concentrator, class of 1992, and left in his final semester twelve credits short of a Bachelor of Arts after film work took priority. He has not completed the degree since, though Harvard awarded him its Arts Medal — a separate honor — in 2013.
Is the “genius” IQ claim about Matt Damon actually about his Good Will Hunting character?
At least one source makes exactly that substitution. brainmanager.io writes that Damon “wasn’t just acting when he played a math genius in Good Will Hunting — he’s widely considered a real-life intellectual,” citing the role as evidence. The film itself never assigns Will Hunting a stated IQ number either.
Did Matt Damon really write Good Will Hunting for a Harvard class?
Yes. He wrote an early draft as the final project for a playwriting class taught by Anthony Kubiak, turning in roughly forty pages instead of the assigned one-act play. He and Ben Affleck spent several years expanding it into the produced screenplay, finishing a version in 1994.
What awards did Good Will Hunting win?
Damon and Affleck won the Academy Award and Golden Globe for Best Original Screenplay. Damon was separately nominated for Best Actor, and Robin Williams won Best Supporting Actor for the same film.
How does Matt Damon’s case compare to other actors on this site?
His closest parallel is Ashton Kutcher — both left a degree unfinished and built something independently documented instead. Natalie Portman is the contrast: the other Harvard name in this category, and the one who actually completed her degree.
