Is Raven's IQ test reliable (how unreliable is the IQ test in your circle of friends)

In the United States in the 1990s, murder can be exempted from punishment-as long as the killer's IQ is low enough. 1996, a man named Daryl Atkins killed an air force soldier and will be sentenced to death. But because his IQ test result is 59, which is lower than the minimum IQ standard of death penalty-70, he survived by luck. What is puzzling is that in 2005, Atkins took another test, but the results showed that he became smarter and his IQ reached 74-76. This is embarrassing. Can IQ really be measured? Is the IQ test that has flourished in recent years reliable?

In the variety show "Run, Brother", Guan Xiaotong has amazing intelligence and lists a lot of XY in minutes. At that moment, she was a goddess.

The movie "Catch Me" tells the story of Frank, a fugitive with high IQ, who keeps forging doctors.

lawyer

Pilot status, etc.

The story of escaping from the FBI and cheating all over the world.

After finally bringing Frank to justice, the detective asked a question he couldn't understand: "How did you fool the judge who took the bar exam and become an assistant prosecutor?" Frank said—

Intelligence can be said to be one of the most desirable talents.

IQ test is also a "game" that everyone enjoys and relishes.

It is said that Einstein's IQ is 200, Hawking's IQ is 220 and Da Vinci's IQ is 230. The person with the highest IQ in the world is william james Sidious, an American genius mathematician. He mastered French at the age of 4 and taught at Harvard University at the age of 9, with an IQ as high as 300.

However, as far as we know, in the Da Vinci era, IQ tests were not "born"! So where does the so-called score come from? And is other people's "high IQ" really reliable?

The earliest IQ test: used to distinguish mentally retarded children

In fact, the purpose of the earliest IQ test is exactly the opposite of the purpose of "discovering genius" now.

It is specially designed to distinguish children with mental retardation.

French psychologist alfred binet is the originator of IQ test.

1904, the French minister of public education gave him a task-because there are always some children in the classroom who can't receive knowledge normally like ordinary children and need special education, so they want to find out these children with abnormal intellectual development before entering school.

So a year later, Binet.Alfred. Alfred and his assistant Simon made the world's first IQ test table, which was specially used to select these children.

Later, the German psychologist William Stern created a method to calculate the intelligence level-dividing the intelligence age by the actual age,

The concept of "IQ" was formally born.

However, Binet.Alfred. Alfred has always refused to rank all children's innate intelligence by IQ.

He believes that intelligence is a complex concept, and a test can't truly reflect everything.

However, people's interest in intelligence testing only increases, and more and more people want to spy out the mystery through intuitive values out of comparison and curiosity.

19 16, American Louis terman revised Binet.Alfred. Alfred-Simon test bench.

The new version was named Stanford-Binet.Alfred. Alfred's intelligence test,

This more comprehensive and detailed test initiated the research of modern intelligence test.

The existing intelligence tests are also famous: Raven's standard reasoning test, Wechsler series scale and so on.

The biggest evil I have ever done in practicing eugenics IQ test.

Although there is no evidence to fully prove the reliability of IQ tests,

But put into practice, it gradually evolved into a "wave" of the opposite of human nature.

Darwin's cousin Francis Galton thought

Excellence is innate and will continue to be passed down with genes. The emergence of IQ test just provides a measuring tool for this theory.

At the beginning of the 20th century, a large number of immigrants entered the United States, at which time the United States was experiencing a serious economic crisis.

Americans think this is all a can of low intelligence genes. As a result, foreign countries have introduced strict immigration control laws, and many people are prohibited from entering the country because of "lack of intelligence"; Internally, the US government has started IQ screening.

Give people IQ tests, and legislate a policy of forbidding children for those they think are mentally retarded.

Under this trend, disabled people have become the first victims.

Subsequently, the poor were also included, and the plan caused more than 60 thousand victims.

There is no doubt that the Nazis gave full play to the negative effects of IQ tests.

The Nazis stipulated that all doctors in Germany must report patients with intellectual disabilities, including various mental diseases, epilepsy, blindness, deafness and physical deformities, or they will be severely punished.

According to statistics, from 1937 to the beginning of the war, about 600,000 people suffered.

How unreliable is the IQ test?

In fact, let alone the so-called authoritative IQ tests we usually do online. Even if you spend more than 3000 yuan to do those tests mentioned above, it may not be reliable.

Look at some problems in intelligence test.

For example, a common-sense question in Webster's adult intelligence assessment: "What should you do if your water pipe breaks?"

There is another example: the function of clocks and watches.

On which day of the month the moon is the roundest, and so on.

Similarly, doctors may not know how to repair water pipes.

There is nothing scientific and rigorous about the examination form, but it is convenient to come.

In order to cope with large-scale testing, the form of single choice is adopted;

Many graphic problems were also due to the fact that a large number of immigrants could not speak English at that time and the language was unreasonable.

Hundreds of years have passed since Binet.Alfred. Alfred published the first set of test questions in 1905.

But many intelligence papers have not changed so far, and they are basically the same.

Therefore, intelligence tests have always been unable to escape the "Flynn effect", that is, the next generation will always score higher than the previous generation.

From the perspective of modern science, scientists have found that,

The cognitive ability of IQ test is only composed of short-term memory, reasoning and verbal agility, and most of them tend to test mathematical and physical abilities.

What is intelligence? Binet.Alfred. Alfred, the founder of the IQ test, did not comment. The inventors of various intelligence assessments did not put forward any theories, or rarely mentioned them.

In short, the current intelligence test has no theoretical basis, but people use their already mastered abilities to group people hastily.

Everyone has his strengths. Believe in yourself rather than IQ!

In order to discuss IQ, a program specially invited seven elites from different backgrounds to do IQ tests, all of whom can be said to be top figures in their respective fields.

The first place, as expected, is Seth Lloyd of quantum physics.

However, he himself felt that the test was unfair.

However, when they take another intelligence test that includes at least eight aspects,

Great changes have taken place in the rankings, and the top three have changed greatly.

However, the dramatist who failed to rank in the traditional single intelligence test rushed to the first place.

Am I the only one who thinks IQ test is an infinite loop? Yu once joked that he and Ma Yun were admitted to the university in the same year, while he was admitted to Peking University. Ma Yun was just a normal school in Hangzhou. Now, where is Ma Yun? However, people have also said that in another 30 years, who might make great contributions to mankind? So, never limit yourself because of a certain label, no matter who it is!
