What is Mark Zuckerberg’s IQ?
A number nobody can source.
The figure of 152 is quoted on hundreds of pages and attributed on none of them. What is on record is a classics-heavy schooling and two years of a Harvard degree he did not finish.
Mark Zuckerberg’s estimated IQ
- Admitted to Phillips Exeter Academy and then to Harvard, where he studied psychology and computer science before leaving in 2004.
- Studied Latin and Ancient Greek at Exeter; classmates and early profiles describe him reading classical texts in the original.
- Wrote and shipped working software as a school student, including the Synapse music player, which drew acquisition interest before he had finished secondary school.
Every input here is a selection decision made by an admissions office, or a product built by a teenager. Both say something. Neither is a test.

What an IQ of 135–145 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.

Mark Zuckerberg was born in White Plains, New York in 1984 and learned to program on an Atari BASIC set-up at home. Before leaving school he had built a messaging system for his father’s dental practice and, with a classmate, the Synapse music player.
At Harvard he studied psychology alongside computer science — a detail usually left out of the founder story, and the more interesting half of it. He launched TheFacebook from his dormitory in February 2004 and left the university later that year without completing his degree.
What follows is the most-documented business career of his generation, and none of it involves a cognitive test. That is the whole point of this page: the record is enormous, and it contains no number.

Mark Zuckerberg: the documented record
The estimate above rests on this record. Every entry here is a matter of public fact, which is more than can be said for the number itself.
- 1984Born in White Plains, New York.
- c.1996Learns to program at home; later writes a messaging tool used in his father’s dental practice.
- 2002Graduates from Phillips Exeter Academy, where he studied Latin and Ancient Greek.
- 2002Releases Synapse Media Player with a classmate before starting university.
- 2003Builds Facemash at Harvard; it is shut down within days.
- 2004Launches TheFacebook in February and leaves Harvard the same year.
- 2012Facebook’s initial public offering.
- 2021The company is renamed Meta.
Where the 152 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.
Zuckerberg is a useful case because the gap between what is known and what is asserted is so wide. His education is a matter of public record. His IQ is not a matter of any record at all.
The 152 has the shape of a number invented to fit a reputation. It is high enough to sound exceptional, low enough to sound plausible, and it arrived after Facebook was already worth billions — not before. Numbers that appear only after somebody becomes famous are describing the fame, not the person.
There is a second problem specific to founders. Company value is not a cognitive measurement: it reflects timing, capital, network effects and a great deal of luck. Reading an IQ back out of a valuation is circular, and it is what almost every figure in this category actually does.
How we read a number →Studied psychology and computer science; left without completing the degree. Received an honorary degree in 2017, which is not an academic qualification.
Classical languages formed a substantial part of his coursework. The strongest documented input to the estimate above.
A machine-learning music player written with a classmate and released free. Reported acquisition interest was never completed.
Searched biographies, interviews, court filings from the 2010s litigation, and school records reporting. Nothing.
Source URLs and first-appearance date pending audit.
No original could be located. The number circulates without attribution.
The sources behind our estimate
The figures that circulate for Mark Zuckerberg, what we were able to confirm, and where the two diverge.
152 is the number that circulates. It appears on celebrity-IQ lists, in quiz apps and in news aggregators, always stated flatly and never sourced.
We found no evidence that Mark Zuckerberg has ever taken or published an IQ test. He has not claimed a score, no biographer reports one, and no school record has been published. The 152 has no origin document that we could locate.
Two clusters, 137 and 152, with no reasoning attached to either. A spread that narrow across so many pages is a sign of copying, not of measurement.

Mark Zuckerberg — frequently asked
What is Mark Zuckerberg’s IQ?
No verified score exists. The 152 that circulates has no traceable source. Our 135–145 range is an estimate inferred from his documented academic record, not a measurement.
Has Mark Zuckerberg ever taken an IQ test?
There is no public record of one. He has never claimed a score, and no biography or interview we could find reports a result.
Where does the 152 figure come from?
No original source could be located. It appears on aggregator pages that cite each other, which is the usual pattern for celebrity IQ numbers.
Did Mark Zuckerberg finish his Harvard degree?
No. He enrolled in 2002 to study psychology and computer science and left in 2004 to work on Facebook full time. His 2017 Harvard degree was honorary.
Does dropping out of Harvard say anything about intelligence?
Getting admitted does; leaving does not. Admission is a selection signal. Departure is a decision about opportunity cost, and in 2004 his was unusually large.
Is a company’s value evidence of its founder’s IQ?
No. Valuations reflect timing, capital and network effects as much as ability. Inferring a score from a share price is circular reasoning, and it is what most figures in this category rest on.
How does my IQ compare with Mark Zuckerberg?
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.
