Abilities change, but IQ scores tend to be very stable. However the intelligence ability is changing during the life, the IQ (intelligence quotient) does not. This measure is defined to have mean of 100 in each age group. So the average IQ e.g. in the age 5 is 100, and the same in the age 50.
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.
These different types of intelligence show different patterns as you get older. Crystallized intelligence "averages 98 at ages 20–24, rises to 101 by ages 35–44, before declining to 100 (ages 45–54), then 98 (55–64), then 96 (65–69), then 93 (70–74), and 88 (75+)," says Kaufman.
Elon Musk IQ is close to this starting point, with an estimated score of 155. The typical genius has an IQ of around 140.
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.

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.
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.
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.
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".
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.
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.

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).
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.
Eleven-year-old Yusuf Shah of England took the Mensa IQ test on a whim — and earned the highest possible score of 162, according to local news reports.
Similar to Einstein, theoretical physicist Stephen Hawking had an estimated IQ of 160, yet it is unknown if he ever took an IQ test, according to enhancingbrain.com. According to Healthline, about 68% of people have an IQ between 85 and 115.
A result on one test of 132 can be the same as a score of 148 on another test. Some intelligence tests don't use IQ scores at all. This is why Mensa keeps it simple with a cutoff of 98%: candidates who have achieved a score at or above the 98th percentile on a standard test of intelligence will qualify for Mensa.
At the top of the list, in the low 130's, are either physicians and surgeons or professors and researchers, depending on the study you look at. The range amongst physicians and surgeons is tightly clustered, whereas the range for professors and researchers is broader.
The Prometheus Society is a high IQ society, similar to Mensa International, but much more restrictive. The entry criterion, achievable by a number of tests, is designed to be passable by 1 in 30,000 of the population, while Mensa entry is achievable by 1 in 50.
Bill gates: iq of 160 | MARCA English.
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.
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).
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.
In addition to slowing down physically, most people lose points on intelligence tests as they enter their golden years. Now, new research suggests the loss of certain types of cognitive skills with age may stem from problems with basic sensory tasks, such as making quick judgments based on visual information.
