The German psychologist William Stern (1871-1938) introduced the idea of intelligence quotient, or IQ. This entailed a formula for mental age that could be assessed by a test, such as the one devised by Binet, divided by chronological age, multiplied by 100.
Alfred Binet (French: [binɛ]; 8 July 1857 – 18 October 1911), born Alfredo Binetti, was a French psychologist who invented the first practical IQ test, the Binet–Simon test.
In 1905, psychologists Alfred Binet and Théodore Simon designed a test for children who were struggling in school in France. Designed to determine which children required individualized attention, their method formed the basis of the modern IQ test.
The abbreviation "IQ" was coined by the psychologist William Stern for the German term Intelligenzquotient, his term for a scoring method for intelligence tests at University of Breslau he advocated in a 1912 book.
The appropriately named Marilyn vos Savant is in a class of her own. According to Guinness World Records, her astonishing IQ of 228 is the highest ever recorded. The daughter of an Italian and a German immigrant, vos Savant was born in St. Louis, Missouri, in 1946.
Kim Ung-Yong
He holds the Guinness World Record for IQ at 210 and he was invited as a guest student in physics at Hanyang University when he was three year old. He was invited to America by NASA at age eight, he worked at the space organization for ten years and then returned to Korea.
Nikola Tesla: IQ 160–310
Nikola Tesla, the Serbian-American inventor—and arch-rival of Thomas Edison—reportedly had an estimated IQ falling somewhere between 160 and 310, depending on the measure.
Researchers have previously shown that a person's IQ is highly influenced by genetic factors, and have even identified certain genes that play a role. They've also shown that performance in school has genetic factors. But it's been unclear whether the same genes that influence IQ also influence grades and test scores.
IQ tests are made to have an average score of 100. Psychologists revise the test every few years in order to maintain 100 as the average. Most people (about 68 percent) have an IQ between 85 and 115. Only a small fraction of people have a very low IQ (below 70) or a very high IQ (above 130).
The reality is that IQ results are usually fairly accurate. The psychologist conducting the test ensures this by making sure they don't just look at the test score in isolation. If they're working with a child, for example, they might take into account other factors.
Albert Einstein likely never took an IQ test but is estimated to have a 160 IQ—but even that can't stand up to these masterminds.
Einstein never took a modern IQ test, but it's believed that he had an IQ of 160, the same score as Hawking. Only 1 percent of those who sit the Mensa test achieve the maximum mark, and the average score is 100. A 'genius' test score is generally considered to be anything over 140.
The lowest IQ score is 0/200, but nobody in recorded history has officially scored 0. Any result below 75 points is an indicator of some form of mental or cognitive impairment.
Although science is on the fence about whether you can raise your IQ or not, research does seem to suggest that it's possible to raise your intelligence through certain brain-training activities. Training your memory, executive control, and visuospatial reasoning can help to boost your intelligence levels.
Scientists don't know exactly what causes someone to be a genius. There is probably a genetic component to your level of intelligence. Certain types of genes influence how much intellectual power you have. Your child's genetic influences affect their motivation, confidence, and other traits.
An individual's IQ does not change with age. In other words: if you did an IQ test now and then another one in 10 years' time, your IQ score will probably be very similar. This is because IQ is always measured relative to other people your age.
Yet, although IQ differences between individuals have been shown to have a large hereditary component, it does not follow that between-group differences in average IQ have a genetic basis. The scientific consensus is that genetics does not explain average differences in IQ test performance between racial groups.
His score was the highest that had ever been obtained. In terms of IQ, the psychologist related that the figure would be between 250 and 300. Late in life William Sidis took general intelligence tests for Civil Service positions in New York and Boston. His phenomenal ratings are matter of record.
IQ 160. If you wonder who has an IQ of 160, the answer is usually Stephen Hawking. Until his death in 2018, Stephen Hawking was one of the most prominent and well-known scientists of the twenty-first century.
One of the most well-known online exams available to you is Free-IQTest.net. It has 20 questions that will measure your IQ score accurately. After this test, you have to give your birth date since the test calculates your IQ score based on your age. This way, you may compare yourself to your peers.
Sir Isaac Newton (1642-1726) was an English physicist and mathematician, most famous for discovering gravity. One of the most celebrated and influential scientists of all time, Newton had an estimated IQ of 193.
