There's no single "highest IQ ever" due to scoring variations, but Marilyn vos Savant is famous for holding the Guinness World Record for highest recorded IQ (around 228), a title she earned in the 1980s before the category was retired for being unreliable. Other contenders for extreme intelligence often cited include mathematicians like Terence Tao (estimated ~230) and prodigies like Christopher Hirata (estimated ~225) and Kim Ung-Yong, but scores vary greatly and often rely on different tests, making direct comparisons difficult, with some sources even listing figures like YoungHoon Kim with 276, though verification is key.
World's highest IQ individuals
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.
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.
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.
Marilyn vos Savant. Marilyn vos Savant (/ˌvɒs səˈvɑːnt/ VOSS sə-VAHNT; born Marilyn Mach; August 11, 1946) is an American magazine columnist who has the highest recorded intelligence quotient (IQ) in the Guinness Book of Records, a competitive category the publication has since retired.
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.
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.
According to some sources, Einstein's IQ was probably about 160, which is commonly considered genius level. This number is largely derived from his achievements in physics.
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.
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%.
Celebrity Genius 5 - James Woods

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.
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.
Kanye West has been known for his outlandish ideas, numerous creative projects, and bids such as running for president. However, does he have the intelligence quotient to back it all up? Kanye claims that his IQ is 133. This puts him at the very top – the 98th percentile.
Tom Hanks as Forrest Gump: At an early age, Forrest is deemed to have a below-average IQ of 75. He has an endearing character and shows devotion to his loved ones and duties, character traits that bring him into many life-changing situations.
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.
Careers in the medical field, computer programing, university research positions, and engineering are among the ones with the highest requirements to be smart and have a high IQ.
IQ tests are not perfect, not should they be used to create a class-ist society ruled by high testers. Paris Hilton has a 129 IQ and Andy Warhol's was 86. But who contributed more to society?
She was a very smart girl (with an IQ of 154), became a bookworm, and once was told that a suitable job for her (and her brains) was to become a lawyer. However, her first love was still the black-and-white movies, especially those featuring.
Her songwriting & business smarts suggest above-average intelligence, but real IQ needs a pro test. Taylor Swift's IQ is often cited online as 160, which would place her in the top 0.01% of the population, higher than 99.99% of people.
Matt Damon
The Hollywood heavyweight, who boasts an IQ of 160, famously completed the project with his longtime friend Ben Affleck.
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.
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.
