Everyone wants a number. We live in a world where we love to quantify greatness, especially when someone is as dominant as Magnus Carlsen. If you've spent more than five minutes on a chess forum or clicked on those "Smartest People Ever" listicles, you've probably seen a specific figure slapped next to his name: 190.
It sounds impressive. It’s legendary. It’s also, quite honestly, almost certainly made up.
The truth about the magnus carlsen iq test is a lot more complicated than a single score. For starters, Carlsen himself has been pretty vocal about the fact that he isn't some walking supercomputer who aced a Mensa exam at age five. He’s actually gone on the record saying he considers himself an "average guy" in many respects, even if the rest of us know that’s a bit of a stretch.
The 190 myth and where it actually came from
So, where did that 190 number start? You'll find it on dozens of websites, often grouped with other legendary figures like Isaac Newton or Albert Einstein. The reality is that these sites are usually just guessing based on his ELO rating or his freakish memory.
There is no record of a formal, proctored magnus carlsen iq test ever being released to the public.
When you look at history, this happens to every great chess player. People used to swear Garry Kasparov had an IQ of 190. Then, in the late 80s, the German magazine Der Spiegel actually put him through a battery of tests. The result? 135. Now, 135 is objectively very high—it's the top 1% or 2% of the population—but it’s not the "off-the-charts" 190 that everyone assumed.
Why chess doesn't always equal high IQ
Chess skill is a very specific type of intelligence. It’s about pattern recognition, calculation, and a specific kind of spatial reasoning.

While there is a correlation between IQ and chess performance, it’s not a perfect 1:1 match. Experts like psychologist Fernand Gobet have studied this for decades. They found that while elite players generally have above-average intelligence, the "genius" level IQ isn't a prerequisite for becoming a Grandmaster.
Magnus is a perfect example of this.
He has an incredible ability to recall thousands of games. He can play 70 people at once and win nearly every game. He even became the world number one in Fantasy Premier League, which, let's be real, might be his most relatable flex. But does that mean he can solve complex differential equations or learn a new language in a weekend? Maybe. Maybe not.
He’s often described his own process as intuitive. He "sees" the right move rather than calculating every single possibility like a machine.
What happened when Magnus actually tried an IQ-style test?
There’s a bit of "insider" lore that's been floating around the chess community for a couple of years. During a casual stream/screenshare with some other high-level players, Magnus reportedly tried a few problems from the AGCT (Armed Services General Classification Test), which is often used as a proxy for IQ.
The score that leaked? 115.

Now, don't go thinking he's "just" slightly above average. Context is everything here. He was reportedly joking around, talking to friends, and not taking it seriously at all. Anyone who has ever taken a proctored test knows that focus is 90% of the battle. If you aren't trying, the number means nothing.
Still, it’s a funny reality check for those who think he has a 200 IQ.
The "Genius" label and Magnus's own take
Carlsen has been remarkably humble about his brains. In various interviews, he’s pushed back against the idea that he’s a general-purpose genius.
"I'm no genius," he told a reporter once. He basically said he's just really, really good at one specific thing: chess.
He’s also admitted to being "lazy" and "chaotic" in his younger years. He wasn't the kid at the front of the class with his hand up for every question. He was the kid staring out the window, likely thinking about a Sicilian Defense variation or a football match.

Most psychometricians and chess experts guess he’d land somewhere in the 130 to 150 range. This is the "sweet spot" for many high achievers. It's high enough to process information at lightning speed, but not so high that it comes with the social or cognitive "noise" that sometimes affects people at the 160+ level.
His real "superpowers" aren't just general intelligence. They are:
- Working Memory: The ability to hold 15-20 moves of calculation in his head across multiple branches.
- Visual-Spatial Processing: Understanding how pieces interact on a 64-square grid without looking at the board.
- Emotional Intelligence (EQ): Knowing exactly when to press an opponent and when to offer a draw. He plays the person, not just the board.
Why the number doesn't actually matter
At the end of the day, a magnus carlsen iq test score wouldn't change his legacy. Whether he scores a 110 or a 180, he is still the highest-rated player in the history of the game. He held the World Championship title for a decade before simply getting bored and giving it up.
Intelligence is multifaceted.
We see it in how he handles his business ventures, like the Play Magnus Group. We see it in his dry, sarcastic humor on Twitter (or X). We see it in his ability to dominate different formats of the game, from classical to blitz.
If you're looking for a lesson in all this, it’s probably that "potential" (IQ) is useless without the obsession to back it up. Magnus didn't become the GOAT because he was born with a high test score. He became the GOAT because he spent his childhood obsessively memorizing flags, capitals, and chess positions until his brain was a finely tuned instrument for that specific craft.
Actionable Insights for the Aspiring Mind
- Don't obsess over your IQ score: Just like Magnus, focus on developing a "deep" skill in one area rather than worrying about a general intelligence metric.
- Train your working memory: Use chess puzzles or N-back exercises to increase the amount of information you can hold in your "mental scratchpad."
- Understand the role of intuition: Once you've mastered the patterns (like Magnus has with chess), learn to trust your "gut" feeling in high-pressure situations.
- Practice deliberate play: Magnus often plays for fun, not just for study. Mixing enjoyment with discipline is the secret to long-term cognitive growth.
The fascination with the magnus carlsen iq test says more about our obsession with numbers than it does about Carlsen’s actual brain. He’s a once-in-a-generation talent, and honestly, that’s more than enough.
