Have you ever wondered what is the highest IQ ever recorded and who is the smartest person in the world, at least according to the IQ test? Well, we will try to give you an answer.
First of all, you have to understand that most people never took the IQ test and that standardized testing began in the 20th century, so we can’t never be completely certain, but the man who is believed to have had the highest IQ score in history is William James Sidis. It is estimated that his IQ was between 250 and 300, but the testing was different from standard IQ tests. With this score he easily beats people like Albert Einstein and Steven Hawking for the top spot.
He entered Harvard University at the age of 11. It was claimed that he was conversant in over forty languages and dialects when he was an adult, although some people doubt that. He was exceptional in both linguistics and mathematics, but also in many different subjects like cosmology and anthropology, where he wrote papers under different pseudonyms.
