The title of the highest IQ in the world is often attributed to individuals like Marilyn vos Savant, an American magazine columnist, who held the Guinness World Record for the highest IQ from 1985 to 1989, with a reported score of 228. However, IQ scores are not always consistent or universally agreed upon, and there are other notable individuals, like Terence Tao, a mathematician who has demonstrated extraordinary intellectual abilities, and Christopher Hirata, an astrophysicist. IQ is just one measure of intelligence and doesn’t necessarily capture the full range of an individual’s cognitive abilities.
