Sad research: IQ of young people in the world is gradually declining

Why did this happen? What is the true nature of IQ?

Social development, people increasingly invest more in education. However, according to a new study, this process seems to bring about the opposite result: IQ of young people today is decreasing compared to World War II.

Specifically, according to experts from Norway, since the generation after 1975, the average has decreased by about 7 points per generation. This is a very strange but somewhat disturbing result - quoted by researchers.

Today's IQ of young people is decreasing compared to World War II.

In fact, this is the predicted prediction of a trend. It is important to know that high IQ only means the ability to calculate and solve complex problems more quickly. This effect is scientifically named "Flynn effect" (Flynn effect) , and often later generations will be better off thanks to the development of society and science.

But human ability cannot rise forever. After a period of 60-70 years of continuously increasing IQ, increasing at least 3 points per decade, that index also decreased.

Study authors Ole Rogeburg and Bernt Bratsberg from the Economic Research Institute Ragnar Frisch (Norway) said that the reduction rate depends on the method of teaching mathematics and language at each school.

However, the reason may be that people are spending too much time enjoying the benefits of technology, rather than reading to absorb more knowledge.

Speed ​​decreases because people are spending too much time enjoying the benefits of technology, instead of reading.

Rogeburg and Bratsberg conducted the survey, then compared with IQ of more than 730,000 people in the period from 1970 to 2009. They found that men's IQ in Norway was lower than their father's when they were together. age.

According to Stuart Ritchie, a psychologist at Edinburgh University, this is one of the evidences of the Flynn effect reversal."If the model they give is correct, this result is very impressive, though a little worrying."

The study was published in the Proceedings of the National Academy of Sciences (US - PNAS).
