There's no single definitive answer for who has the absolute highest IQ, as scores vary and historical figures' IQs are estimated, but YoungHoon Kim (South Korea, IQ 276) is often cited for the highest recorded score, while William James Sidis (IQ 250-300) and Nikola Tesla (IQ 160-310) have famously high ranges. Other top contenders include Marilyn vos Savant (228) and mathematician Terence Tao (210-230), though IQ tests have limits, especially for historical figures or extremely high scores.
YoungHoon Kim (IQ 276)
According to the recent reports, YoungHoon Kim, South Korea, has the highest recorded IQ as of 2024, with a score of 276. His intelligence has been verified by various organizations, including the Giga Society and the World Genius Directory.
Because there is no single standardized test that measures intelligence, determining the highest IQ ever will always be contentious. Bearing these caveats in mind, it is generally believed that the highest IQ score ever recorded is that of William James Sidis, who is believed to have had an IQ of between 250 and 300.
Snoop Dogg has publicly stated he has an IQ of 147, a score that falls into the "highly gifted" or "genius" category, much to his own surprise given his self-described average school performance (straight Cs). While this self-reported score suggests exceptional intellect, IQ tests measure specific cognitive abilities, and success in life and business (like Snoop Dogg's multifaceted career as a rapper, entrepreneur, and media personality) reflects a broader range of intelligence and skills.
We all know that Gaga is a creative genius, but it turns out she's an actual genius too with a widely-estimated IQ of 166, making her “exceptionally gifted” — and we don't disagree!
Kanye West (Ye) publicly claimed to have a 142 IQ in an April 2025 social media post, a score he stated meant he had a "genius intellect," though this remains an unverified, self-proclaimed figure not supported by official test results. While supporters praised the claim, many questioned its accuracy, and there's no official, independently verified IQ score for him, with intelligence being a multifaceted concept beyond a single number.
A 72 IQ is considered Borderline Intellectual Functioning (BIF), falling just above the threshold for intellectual disability (usually around 70), placing it in the lower end of the spectrum (70-79) and indicating slower learning and potential needs for support in daily living, though it's not low enough for an official intellectual disability diagnosis by itself, notes Quora user. It's in the bottom few percentiles of the population, requiring more time to grasp complex concepts but not necessarily severe impairment.
Stephen Hawking never officially revealed his IQ, and often dismissed the metric, famously saying, "People who boast about their IQ are losers". While estimates place his IQ around 160, a genius level, this is speculative; Hawking emphasized that creativity, persistence, and passion for science were more important than a single score, despite his profound impact on physics.
No, an IQ of 97 is not considered dumb; it falls squarely in the average range (90-109), indicating typical cognitive abilities, though some tests might place it slightly below the exact midpoint of 100. An IQ score of 97 means you performed better than 42% of people, and due to the test's margin of error, your score could be anywhere from the high 80s to the mid-100s, still within normal intelligence.
Meaning of IQ
85 to 115 - Two thirds of us have an IQ in this range: the 'average' IQ is 100. Over 135 - You are in the top 1%.
Is Kim Kardashian's IQ really 190? No—it's a baseless rumor from unreliable sites. No verified score exists; estimates range 95–119 based on her education & career, but her actual IQ remains unknown.
Although IQ can change for an individual, across a population it is well established that IQ is stable across the lifespan. This does NOT mean that our abilities do not change as we age. IQ (as the name indicates) is a QUOTIENT, i.e., your score is calculated relative to persons of your age.
Matt Damon
The Hollywood heavyweight, who boasts an IQ of 160, famously completed the project with his longtime friend Ben Affleck.
It's often said (with scant evidence) that his IQ was 160; even if true, that would make him less intelligent than thousands of people alive today. In terms of mathematical ability, Einstein would not come close to matching today's leading physicists like Stephen Hawking.
Studies have shown that intelligence has a genetic component, but they have not conclusively identified any single genes that have major roles in differences in intelligence. It is likely that intelligence involves many genes that each make only a small contribution to a person's intelligence.
Leonardo da Vinci: IQ 180–220
While IQ tests weren't around when Leonardo da Vinci was living, some have estimated that his score would have been between 180 and 220. Like other people considered geniuses, he had a wide range of skills, excelling in everything from art and science to music and architecture.
Celebrity Genius 5 - James Woods
Emmy Award winner James Woods is an Oscar-nominee and superstar has a whopping IQ of 180. While in high school, Woods was in a UCLA linear algebra course.
Stephen Hawking's "last words" aren't a single phrase but a collection of final messages from his speeches and posthumously published book, emphasizing bravery, hope, curiosity, and the scientific explanation of the universe over divine intervention, with parting advice to "look up at the stars and not down at your feet" and to "be brave, be determined". His final book, Brief Answers to the Big Questions, published after his death in 2018, summarized his lifelong views, stating there is no God and that the laws of nature explain existence, a conclusion stemming from his belief that science provides answers where religion often invoked a creator.
To calculate IQ, take a person's mental age, divide it by chronological age, and then multiply that number by 100. For example, if a person has a mental age of 12 but is 10 years old, then you'd divide 12 by 10, and multiply that number by 100, which would result in an IQ of 120.
Traditionally, cognitive or intellectual functioning has been measured through the intelligence quotient (IQ) tests, with an IQ of less than 70 recommended for a clinical diagnosis of Intellectual Disability.
Breakdown of Scores on an IQ Scale
Lady Gaga's IQ is widely rumored to be around 166, placing her in the "exceptionally gifted" or genius category, though this is an estimation often cited in celebrity lists, not a officially verified number from a public test. This high estimate is supported by her early academic achievements, like attending a summer program for the top 1% of students, and her demonstrated creative and musical genius as a composer and performer, notes Us Weekly and Brainmanager.io.
Ben Affleck's IQ is often cited as 154, placing him in the highly gifted range, though these figures for celebrities are estimates, with some sources also mentioning high intellect in relation to his work, such as co-writing Good Will Hunting with Matt Damon.
“I went to this doctor … My wife took me to do that because she said, 'Something about your personality doesn't feel like it's bipolar, I've seen bipolar before. ' And I've come to find that it's really a case of autism that I have,” West said. West said the diagnosis has helped him better understand himself.
