Is math a good intelligence test
The IQ test Completely overrated or really important?

Aside from wealth and beauty, there is probably no other quality that is as highly regarded as intelligence. That mental flexibility to be able to deal with knowledge quickly and in a goal-oriented manner. Can intelligence tests measure this ability?
IQ measurements on monozygotic and dizygotic twins have shown that at least 50 percent of the differences in intelligence between people in our culture have genetic causes. The other part is determined by environmental factors, by siblings, the peer group and formative events. So the human being does not come into the world as a finished being, but still has a lot of potential for development.
Fitness training for intelligence
Is Intelligence Hereditary? This question has now been answered: fifty percent.
Intelligence researchers differentiate between crystalline and fluid intelligence. Crystalline intelligence is the knowledge that can be acquired in school, for example. It can grow for a lifetime. Fluid intelligence is the ability to react appropriately to new requirements. This fluid part of intelligence is considered to be largely innate and already declines at the age of 20. For professor em. Walter Perrig from the University of Bern meant this kind of intelligence above all to be able to solve unknown problems. With special training, he was able to prove that not only can the performance of a person's working memory be improved, but that their overall intelligence can also be increased.
Smart minds filter better
Researchers at the University of Rochester wanted to find out whether human optical perception differs depending on the intelligence quotient. The result of the IQ test surprised even them: subjects with a high IQ were able to recognize more quickly that an image with stripes was moving. However, when it came to recognizing something in the background, they were significantly slower than people with a lower IQ. The US researchers interpret it as follows: In more intelligent people, the brain filters out unimportant information. These would not even be processed. Previous IQ tests often suffer from the fact that they contain verbal tasks and are specifically tailored for people from our culture. The new test could therefore be a culture-independent method to test the intelligence of an individual, according to the researchers.

One intelligence or many?
What is intelligence "Intelligence is what the intelligence test measures" was the definition of the biochemist and science fiction author Isaac Asimov (1920-1992). For a long time people believed in a uniform "intelligence factor", then scientists divided intelligence into sub-areas (mathematical, emotional, linguistic intelligence). But the US psychologist Howard Gardner's theory of "multiple intelligence" is also controversial.
Because intelligence is even more: creativity, musical skills or athletic ability are also types of intelligence. But whether people with these talents are also successful depends on completely different factors. People who want to be successful in the creative or musical field must be able to make the most of their strengths, compensate for their weaknesses and make the best of their abilities. Only then does their special intelligence lead to success.
Where is the intelligence located?
In the brain there is no intelligence area or anything concrete that could be measured and that alone determines our intelligence, emphasizes intelligence researcher Elsbeth Stern from ETH Zurich. In the genes, too, there is no specific place where intelligence is at home. There is no such thing as one intelligence gene. There seems to be an extremely complex interaction between different genes that contribute to the development of intelligence.
"A very high level of intelligence is the result of lucky coincidences in the formation of egg cells and sperm as well as in fertilization. Therefore, the child of highly intelligent parents is very likely to be less intelligent than these. Conversely, less intelligent parents can also carry genetic material that their offspring in helps a just society to soar to unimagined heights. "
Elsbeth Stern, teaching and learning researcher at the ETH Zurich
Intelligence cannot be measured objectively
Good test results in an IQ test cannot be achieved by chance, but weaker ones can.
Training your intelligence is one thing, but measuring it is another. For example, the New Zealand intelligence researcher James Robert Flynn found out in 1984 that the people of the industrialized nations have on average been getting smarter since the beginning of the 20th century - measured by the intelligence quotient calculated in IQ tests (Flynn effect). But are they really getting smarter, or have people just learned to think according to the logic of tests? Even the inventor of intelligence tests, the French psychologist Alfred Binet, admitted as early as 1900 that intelligence was not measurable. Many other critics followed him, such as the renowned biologist and evolutionary researcher Stephen Jay Gould. He is convinced: "The measurement results that an IQ test delivers are nothing more than statistical artifacts."
"The complexity of the modern world requires our brains to adapt and thus increase the IQ. The IQ has increased over the past hundred years."
James Flynn has been involved in the assessment of intelligence tests for decades.
Daring thesis: people are getting dumber and dumber
American developmental biologist Gerald Crabtree of Stanford University claims that the average human intelligence is gradually waning. His reasoning: Thousands of years ago, when people were still roaming the wilderness in small groups, the brightest would have had the best chance of survival. But since mankind has been farming and living together in larger communities, the intelligence of the individual has become less important. Human intelligence may have peaked around 6,000 to 2,000 years ago - from then on it went downhill, says Crabtree. He even suspects that a citizen of ancient Athens was spiritually clearly superior to us today.

Intelligent and individual
It's not just people who are intelligent. There are also clever animals that can hold a candle to us in some situations, for example dolphins, ravens and - with their collective intelligence - also bees.
But plants also communicate with each other and even call out "for help" when they are attacked. You are amazingly intelligent and sensitive.
