Human IQ refers to a measurable assessment of human intelligence, expressed in points. The IQ varies from person to person, so it's worth figuring out what its level can be considered normal.
Age
It is statistically proven that IQ changes with age. It reaches its peak by the age of 25. It is generally accepted in the world that an IQ of 100 points is the average. The IQ of a five-year-old child reaches 50-75 points, at 10 years old it ranges from 70 to 80 points, at 15-20 years old he can reach the average value for an adult of 100 points. In many countries of the world (for example, the USA and Japan), gifted children are selected on the basis of IQ tests, and then they undergo training according to an enhanced and accelerated system. This is due to the fact that children with an increased IQ for their age tend to learn much better and faster than their peers.
Race
As strange as it sounds, IQ varies from race to race. For example, the average IQ for African Americans is 86, for whites of European descent it is 103, and for Jews it is 113. All this speaks in favor of the supporters of scientific racism. However, this gap is narrowing from year to year.
Floor
Women and men do not differ from each other in intelligence, but, according to statistics, the IQ between them differs depending on age. Boys under the age of 5 are somewhat smarter than their peers, but starting from the age of 10-12, girls are ahead of boys in development. This gap fades to naught by the age of 18-20.
Normal IQ
The IQ of an adult depends on many factors - genetics, upbringing, environment, race, etc. Although the average IQ is about 100 points, it varies from 80 points to 180. This IQ limit is laid down in the classic IQ test, developed by the English psychologist Hans Eysenck in 1994. In order to obtain adequate data on this test, it must be passed once in a lifetime in adulthood. Retrying distorts and overestimates the results.
If the IQ is below 80 points, then this indicates the physical and mental deviations of a person. If the IQ exceeds 180 points, then this indicates the genius of the owner of such points. But these dependencies are very conditional. For example, the great physicist Albert Einstein was the most lagging behind in his class in academic performance, which did not prevent him from developing the theory of relativity in the future. And on the other hand, according to the Guinness Book of Records, the ten-year-old American Marilyn Wo Sawan had the highest IQ of 228 points in 1989. This is where personal achievements end for her.
