High IQ people usually score above 130 IQ points, depending on which test is used. The top 1% of intelligent people in the world, according to these tests, have an IQ of over 145.
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%.
An IQ of 120, therefore, implies that the testee is brighter than about 91% of the population, while 130 puts a person ahead of 98% of people.
The standard scores on most other currently normed IQ tests fall in the same range. A score of 160 corresponds to a rarity of about 1 person in 31,560 (leaving aside the issue of error of measurement common to all IQ tests), which falls short of the Mega Society's 1 in a million requirement.
130 to 144: Moderately gifted. 145 to 159: Highly gifted. 160 to 179: Exceptionally gifted. 180 and up: Profoundly gifted.
How did you score on this IQ test? 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".
For example, on The Wechsler Adult Intelligence Scale and the Stanford-Binet test, scores that fall between 90 and 109 are considered average IQ scores. On these same tests, scores that fall between 110 and 119 are considered high average IQ scores. Scores between 80 and 89 are classified as low average.
Born in Moscow in 1976, Nadia Camukova was estimated to have an IQ of 200. The Brain Research Institute located in Moscow reported later on that she had the highest IQ in the world. She can speak seven languages and eight Turkish dialects. Currently, she's a professor at Bahçeşehir University in Turkey.
There are different ways to measure IQ, but they all rely on similar principles, which means it's possible to increase your IQ with study and training. Improving your IQ can help you to improve your problem-solving and lateral thinking skills, which can be useful in many careers.
Can IQ change with 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.
For a mean of 100 and standard deviation of 15 as on most IQ tests that means a person with an IQ of 200 is about 6.67 standard deviations above the mean. That means the odds of a given person having an IQ that high are about 1 in 1e20th.
That's about one in every 250 people. But one leading researcher in the 1940s suggested that a genius should have an IQ over 180. That's about one in every 2 million people.
Critical interpretation of full-scale IQ scores. To further simplify it: An IQ of 75 means that an 8-year-old child will function intellectually overall at 75% of the average 8-year-old's intellectual functioning ie, at an average of a 6-year-old level.
The average IQ of a 15-year-old is 100. This figure is based on general IQ tests, which measure verbal reasoning, problem solving and other cognitive skills. How good is my IQ of 120 for a 15 year old? Great.
Is a 120 IQ good? An IQ score of 120 is a good score since it means superior or above-average intelligence. What is a good IQ score? A score of 100 is said to be the average IQ and anything above that is above average intelligence for the person's age.
Other people with some of the highest IQs are Sho Yano, who had an estimated IQ of around 200 at 10 years old, and Adragon De Mello, who had a projected IQ of 400 and graduated from the University of California, Santa Cruz at 11 years old, according to Reader's Digest.
With an IQ of 400, you'd be the smartest person to ever exist in the history of the world. You would know literally everything and there would be know escape from that. You'd be in the 100th percentile and would exceed everybody in high IQ societies as high as the Mega Society.
No. We think the upper limits of intelligence are somewhere around 250 on a deviance scale normed to 100 and a standard deviation of 15 or 16. There's a difference in kind of intelligence and in brain organization/connectivity above 160, and we'd likely need another leap in kind of intelligence to get much past 250.
