Your IQ score is determined by standardized testing. In other words, a wide range of people take the test, and then the scores are calculated based on each person's performance. When the test is subsequently taken by humans, they are compared to the standard, and this places them in certain percentages of information.
Research shows that about 68% of people have an average IQ. But what is the average IQ determined by? What does IQ really mean, and what causes a person to be more than average?
What is IQ?
There is a short IQ for Information Sharing. It is used as a measure of human intelligence, and intellectual capacity. Different tests can be used to find out what your IQ is. These tests ask you questions designed to challenge your reasoning and problem-solving skills. The results of your test are then compared to the average.
The modern interest in information testing in the United States comes from the work of French psychologist Alfred Binet. It developed a test that assessed basic intellectual functions in school children, as well as assistance in diagnosing mental health disorders. Then, in 1908, Henry Herbert Goddard transferred the Binet trial to English.
While Goddard initially used the test in his work with children with intellectual disabilities, he introduced the test into public schools by 1911. By 1914, an information test was used as evidence in court.
IQ content is somewhat controversial, as scientists and psychologists have long sought to determine the impact of genetics, socio-economic status and location on IQ scores. Sometimes the test methods come twice.
There are many different tests, with their own approach and possible IQ range. Since each test is different, basically no need to say what your IQ score is let alone the test you made.
Among the best known IQ tests are: t
- Cattell III B
- Culture Fair
- Advanced Beef
- Standard Ravens Matrices
- Wechsler Children's Information Scale (WISC-V) t
- Wechsler Adult Information Scale (WAIS) t
- Stanford-Binet Information Scale
- Differential Capacity Scales (DAS) t
- Peabody Single Achievement Test
Average as average
The average IQ test score is, by design, 100, with about 68% of people falling within 15 points side by side of that score. Having tested a wide range of people, scientists standardize the results to an average of 100. However, this does not tell the whole story. The average IQ actually varies from country to country, with different studies having different results.
According to a study in 2010, countries with the highest average quality are:
- Hong Kong; Singapore – 108
- South Korea – 106
- China; Japan; Taiwan – 105
- Iceland; Switzerland; Macau – 101
- United Kingdom; Austria; The Netherlands; Norway; Luxembourg; Liechtenstein – 100
The USA sits on average 98. This puts the United States in 24th from 108 countries and provinces. The other countries with the same score are Australia, the Czech Republic, Denmark, France, Latvia and Spain.
According to the same study, the countries with the lowest average test are:
- Kenya; Namibia; South Africa; Tanzania; Zimbabwe – 72
- Botswana; Ghana; Zambia – 71
- Nigeria – 69
- Swaziland – 68
- Lesotho – 67
- Mozambique – 64
- Malawi – 60
It also shows that the IQ is not a guarantee of success in life, where motivation, attitude and perseverance can make all the difference. Scoring genius levels does not mean that you will not move to immediate success, just because there is no reason to limit ambitions or assume that you are unhappy.
One of the interesting phenomenon in the field of IQ testing is that scores get higher. This is known as Flynn's name, named James Flynn, the scientist he discovered in the 1980s. He noted that soldiers undertaking IQ tests in the 80s scored significantly higher than their counterparts who did the same test in the 1950s. An investigation of this effect showed that the scores of people were continuously improving between three and ten points every ten years.
The way in which the tests are standardized means that a person who scores 100 on an IQ test today would be considered an expert according to the 1900s standards. On the other hand, an IQ of 70 years ago would have had an IQ of 70 years ago, which is low enough to have an intellectual disability.
The reasons for this increase were not definitively determined, but scientists believe it is the result of improvements in nutrition, health care, vaccination and education. The greatest gains were seen in abstract thinking and reasoning, and improvements in arithmetic and vocabulary were much smaller. This reflects the changing way of life as a driver for the increase in overall information.

Genetics influences the most important and controversial topics in the field of information testing. The general scientific consensus is that genetic and environmental factor scores mainly affect IQ scores. There is always a debate about how they interact directly, and which is more effective.
It is of interest, in poorer families, that environmental factors cause most of the differences in IQ scores, and that there is minimal genetic impact. It seems to be the opposite in richer families, where genetic differences contribute significantly to the different levels of IQ.
“The average IQ in America is – and this can be created mathematically – on average.” – P. J. ORourke
What is the average IQ? The answer depends on where you are in the world, and what test you are doing. For the tests, the average is 100, and everyone is compared to that score. It is generally considered that there is a score of 85-115 within the average, as most people within this group are suited. If you are in the best 2%, you are genius according to the tests.
But what you might do depends on your choices. As Stephen Hawking said, “People who are proud of the IQ are losers.” If you believe your IQ is above average, you can always contact Mensa and the steps you can take.
