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.
Alfred Binet and the First IQ Test
So, it was important to find a way to identify the kids who would need extra help. In 1904, as part of this effort, the French government asked Binet to help decide which students were most likely to experience difficulty in school.
While Binet's original intent was to use the test to identify children who needed additional academic assistance, the test soon became a means to identify those deemed "feeble-minded" by the eugenics movement.
IQ is important in understanding abilities and overall achievement. A child with an IQ of 70 will likely have a more difficult time understanding and completing work in a traditional classroom. A child with an IQ of 130 may be “bored” or disinterested in the work in the traditional classroom.
Introduction to IQ
The term 'IQ' was coined in 1912 by the psychologist William Stern in relation to the German term Intelligenzquotient. At that time, IQ was represented as a ratio of mental age to chronological age x 100.
Most people you meet are probably average, and a few are extraordinarily smart. Just 2.2 percent have an IQ of 130 or greater. What's fascinating is that people who score well on one of the tests tend to score well on them all.
It is likely that a large number of genes are involved, each of which makes only a small contribution to a person's intelligence. Other areas that contribute to intelligence, such as memory and verbal ability, involve additional genetic factors. Intelligence is also strongly influenced by the environment.
An average person scores 100 on an IQ test using the Stanford-Binet IQ scale. A score of 137 to 160 is considered the top 1 percent to .

Kids who score higher on IQ tests will, on average, go on to do better in conventional measures of success in life: academic achievement, economic success, even greater health, and longevity.
Most people have an average IQ between 85 and 115. Overall, about 98% of people have a score below 130. Only 2% of the population score above that and are considered above average.
William James Sidis has the World's Highest IQ. Anywhere from 250 to 300 is his IQ score, almost twice the score of Albert Einstein. At the age of eleven, William famously entered Harvard University, becoming the youngest person to enter. He also claimed to be conversant in 25 languages.
Like all statistical quantities, any particular estimate of IQ has an associated standard error that measures uncertainty about the estimate. For modern tests, the confidence interval can be approximately 10 points and reported standard error of measurement can be as low as about three points.
His performance beats those of physicists Stephen Hawking and Albert Einstein, who were both estimated to have IQs around 160.
The German psychologist William Stern (1871-1938) introduced the idea of intelligence quotient, or IQ.
The IQ was originally computed as the ratio of a person's mental age to his chronological (physical) age, multiplied by 100. Thus, if a child of 10 had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), then the child was assigned an IQ of (12/10) X 100, or 120.
There are several successful entrepreneurs who are known for their high IQ scores, such as: Jeff Bezos: The founder of Amazon, Bezos has an IQ estimated to be around 145.
Kanye says he scored a 133 on Mensa IQ test, compares his brain to women's bodies.
Marilyn vos Savant (/ˌvɒs səˈvɑːnt/; 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.
An IQ score over 140 indicates that you're a genius or nearly a genius, while 120 - 140 is classed as "very superior intelligence". 110 - 119 is "superior intelligence", while 90 - 109 is "normal or average intelligence".
Does an individual's IQ change with age? 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.
Yes. However, there is heavy debate over exactly how IQ and intelligence change with age. Studies have demonstrated that a person's fluid intelligence tends to decrease starting in their late 20s, while their crystallized intelligence tends to increase as they grow older.
