We’re obsessed with numbers. We love to rank things, especially people. Whether it’s a net worth, a follower count, or a golf score, humans crave a metric to decide who is "winning." It gets weirder when we talk about intelligence. We’ve spent decades trying to pin down the "low IQ famous people" label on certain stars, usually because they said something goofy in an interview or don't know where France is on a map. But IQ—that rigid, 19th-century invention—is a notoriously fickle beast when you apply it to the chaos of fame.
Intelligence is messy. Honestly, it’s mostly just a measure of how well you take a specific kind of test. When people search for celebrities with low IQs, they’re usually looking for a "gotcha" moment. They want to see that the person with the $50 million mansion is actually "dumber" than they are. It’s a comfort thing. But if you look at the history of these scores, you realize that most of the famous names attached to low numbers are either victims of bad testing, learning disabilities, or just really good at a different kind of "smart."
The Reality of IQ Scores in Hollywood
Let’s get one thing straight. Most celebrities have never actually released their MENSA results. Why would they? If you’re a massive movie star, there is zero upside to telling the world you scored an 85. Most of the lists you see floating around the internet about low IQ famous people are based on rumors, or worse, they’re based on "projected" IQs calculated by researchers who never even met the person.
Take Andy Warhol. People love to cite Warhol as having an IQ around 80 or 86. That’s technically in the "low average" or "borderline" range depending on which scale you use. But look at what the man built. He essentially invented the modern concept of branding. He saw where the world was going 40 years before it got there. If a man can manipulate the entire global art market and become a household name by painting soup cans, is he actually "unintelligent"? Or did he just struggle with the specific logical-mathematical puzzles found in a standard IQ test?
Warhol likely had a learning disability. He was known to be a poor student and struggled with reading. In the mid-20th century, if you couldn't read well, you were labeled as having a low IQ. Today, we call that dyslexia. It’s a hardware issue, not a software issue.
Sylvester Stallone and the Power of Low Expectations
Then there’s Sylvester Stallone. For years, the rumor mill has tried to peg him as one of those famous people with a low IQ, mostly because of his slurry speech and the "meathead" characters he played in the 70s and 80s. People saw Rocky Balboa and assumed the actor was the character.
That’s a mistake. Stallone wrote the screenplay for Rocky in about three days. He refused to sell the script unless he was the lead, turning down life-changing money when he was literally broke with a pregnant wife. That’s high-level strategic thinking. It’s "street smarts" mixed with a deep understanding of narrative structure. Yet, because he doesn't sound like a Harvard professor, he gets lumped into the "low IQ" category by people who don't know better.
Why We Get Intelligence So Wrong
The problem is the G-factor. Psychologists like Charles Spearman argued that there’s a general intelligence that underlies everything. If you’re good at math, you’re probably good at logic. If you’re good at logic, you’re probably good at language.

But modern science is moving away from that. Howard Gardner’s theory of multiple intelligences suggests you can be a "genius" in one area and totally "low IQ" in another.
- Kinesthetic Intelligence: This is what athletes and dancers have.
- Interpersonal Intelligence: This is the "rizz" that makes a movie star a movie star.
- Visual-Spatial Intelligence: This is how a director sees a shot before the camera even moves.
You might find a famous athlete who can’t solve a quadratic equation to save their life. On paper? Low IQ. On the field? They are processing thousands of variables in real-time with more precision than a supercomputer. Who’s actually smarter there?
The Case of Muhammad Ali
Muhammad Ali is a prime example. When he took the Army Induction Test in the 1960s, his IQ was measured at 78. By the standards of the time, he was considered "mentally deficient" for military service.
"I said I was the greatest, not the smartest," Ali famously joked.
But think about Ali’s verbal wit. His poetry. His ability to psychologically dismantle an opponent before a single punch was thrown. He was a master of language and social manipulation. His "low" score was likely a result of his environment, his education, and perhaps a lack of interest in the test itself. It certainly wasn't a reflection of his brain's actual capacity to function at an elite level.
Misconceptions About Fame and Brainpower
There's this weird bias where we assume that if someone is attractive or "vamping" for the camera, they must be dim-bulbs. This is where the low IQ famous people trope really takes off.
The "Dumb Blonde" Archetype
Marilyn Monroe is the classic example, though she’s actually the opposite of the trope. People assumed she was "low IQ" because of the characters she played. In reality, she was an avid reader who owned hundreds of books and studied at the Actors Studio under Lee Strasberg.

On the flip side, you have reality TV stars who lean into the "stupid" persona because it’s profitable. Jessica Simpson’s "Chicken of the Sea" moment made her millions of dollars. Was she actually confused about whether she was eating tuna or chicken? Maybe. But she used that moment to build a billion-dollar fashion empire. Most "smart" people don't have a billion dollars in the bank.
Why Tests Fail Celebrities
Many people who end up in the spotlight come from non-traditional backgrounds. If you grew up in poverty or left school at 14 to pursue acting or music, you aren't going to do well on an IQ test. These tests are culturally biased toward people who stayed in formal education.
- They reward patience.
- They reward "test-taking skills" rather than raw processing power.
- They require a specific type of English fluency.
If you take a kid from the Bronx who is a lyrical genius in hip-hop and give them a standard IQ test, they might score low. Does that mean they are one of those "low IQ famous people"? Or does it mean the test is broken?
The Science: Can IQ Actually Change?
Here’s something the "IQ is destiny" crowd hates: IQ isn't static. It’s not like your height.
The Flynn Effect shows that average IQ scores have been rising worldwide for decades. This suggests that environment, nutrition, and education play a massive role. When we look at famous people who supposedly have low IQs, we’re often looking at a snapshot of a person who maybe didn't have the right tools at the time.
Furthermore, neuroplasticity tells us the brain can "re-wire" itself. You can actually train your working memory and your processing speed. Many stars who were told they were "slow" in school later became polymaths because they finally found a subject that clicked for them.
When "Low IQ" is Actually Neurodivergence
A lot of the folks on these lists are just neurodivergent.

- ADHD can make a timed IQ test a nightmare.
- Autism can cause a massive "spiky profile" where you're a genius at math but can't pass the verbal section.
- Dyscalculia makes the math section impossible.
In the past, these nuances weren't understood. You were just "dumb."
Lessons We Can Actually Use
So, what do we do with this info? If we stop looking for low IQ famous people to make ourselves feel better, what’s the takeaway?
Basically, it's about "Cognitive Diversity." We need to stop valuing one specific type of intelligence over all others. If the world was only run by people with 160 IQs who were good at puzzles, we’d have no art, no music, and no professional sports. We’d probably also have a lot fewer successful businesses, because high-IQ individuals are often more risk-averse.
The most successful people in the world—the ones we see on our screens—usually have a high "Emotional Quotient" (EQ) or "Adversity Quotient" (AQ). They can handle being told "no" a thousand times. They can read a room. They can convince a producer to give them $200 million for a movie. That is a form of genius that an IQ test will never, ever capture.
Actionable Insights: Moving Beyond the Number
- Audit your own "Spiky Profile." Don't worry about an overall IQ score. Figure out where your specific peaks are. Are you better with people or patterns?
- Ignore the "Dumb" Branding. If you see a celebrity being mocked for their intelligence, look at their business moves. Often, the "dumb" persona is a mask used to lower an opponent's guard.
- Prioritize Skill Acquisition. Raw intelligence is like a fast car with no gas. Skills are the fuel. A person with a 90 IQ and a massive work ethic will almost always outperform a 140 IQ person who stays on the couch.
- Practice Critical Consumption. Next time you see a "List of Low IQ Celebs," check the source. Is there a link to a clinical study? Probably not. It's usually just clickbait designed to trigger your ego.
Stop measuring your worth—or the worth of others—by a single number. The most "intelligent" thing you can do is recognize that intelligence has a thousand different faces. Most of them don't look like a standardized test.
The real winners are the ones who figure out what they’re good at and double down on it, regardless of what some school psychologist said about them forty years ago. Focus on your output, not your "potential" on paper. That's how you actually get ahead in a world that’s obsessed with labels.
