IQ peaks at around 20-years-old and later effort will not improve it much beyond this point, research finds. The complexity of people's jobs, higher education, socialising and reading all probably have little effect on peak cognitive ability.
Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline.
The largest increase in human IQ is observed from 2 to 12 years and at the age of 19-20 IQ reaches its maximum. Then there is a period of stabilization of intelligence.
A clear decline is evident.
The mean WAIS-IV IQ is 100 for ages 20-24 and is 99 for ages 25-44. Then it drops to 97 for ages 45-54, to 94 for ages 55-64, to 90 for 65-69, to 86 for ages 70-74 and to 79 for ages 75+.
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.
Elon Musk IQ is close to this starting point, with an estimated score of 155. The typical genius has an IQ of around 140.
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".
Yes, your IQ can change over time. But [IQ] tests give you the same answer to a very substantial extent, even over a period of year. The older you are, the more stable your test score will be. The most volatility in IQ scores is in childhood, mostly in adolescence.
The IQ 125 score is substantially above the norm on all measures, as the typical range on most scales is 90 to 109. On certain current scales, such a high score is also referred to as "above average." In any case, it is one of a kind.
The cause of the IQ decline is due to environmental factors, and not genetics, said Ole Rogeburg, a senior research fellow at Ragnar Frisch Centre and co-author of the study on IQ scores, published in the Proceedings of the National Academy of Sciences journal.
Across 142 effect sizes from 42 data sets involving over 600,000 participants, we found consistent evidence for beneficial effects of education on cognitive abilities of approximately 1 to 5 IQ points for an additional year of education.
According to Wonderlic, a score of 20 to 27 is the particular range that best fits with the successful performance of police work. The national median score for police officers is 21, the equivalent of a 104 IQ, or just slightly above average.
Smarter than Einstein? 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.
Notably, the average IQ score falls between 85 and 115. A score above 140, meanwhile, is considered to be genius level.
Training your memory, executive control, and visuospatial reasoning can help to boost your intelligence levels. The best way to train these areas of your brain is to engage in thoughtful activities and games, learn new skills, and keep your brain active.
Scores of 110-119 are High Average. An IQ of 125 is considered by many schools to be “gifted.” Scores of 120-129 are Superior. And scores above 130 are Very Superior. IQ scores are based on a person's test performance compared to others their age.

The minimum accepted score on the Stanford–Binet is 132, while for the Cattell it is 148 and 130 in the Wechsler tests (WAIS, WISC).
No one knows what Mark Zuckerberg IQ is since he failed a conventional IQ test. Various sources, however, estimate it at 152 IQ based on biographical data, publications, and achievements. He is regarded as a genius and among the world's most intellectual individuals.
Adragon De Mello: IQ 400
In 1988, when Adragon De Mello graduated from the University of California, Santa Cruz, with a degree in computational mathematics at the age of 11, he was the youngest college graduate in the United States (a record he no longer holds).
Kim Kardashian IQ is estimated to be 190. Although some people are known to have IQs above 200, the theoretical maximum IQ in the world is 200. This IQ demonstrates that Kim is among the smartest people in the world. With a $1 billion net worth, Kim Kardashian is ranked 17th on the Forbes World Billionaires list.
I. What is Ted Bundy IQ? A test result revealed that Ted Bundy's IQ was 136, which is considered "gifted." The University of Washington awarded him a psychology bachelor's degree. He used cunning to lure his victims in close by tricking them, including making up injuries and passing for a police officer.
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.
