Are Humans Getting More Intelligent? New Study Confirms Rising Global IQs

Is human intelligence declining or is IQ rising? According to a new study by psychologists at King's College London, we are smarter, but it depends on which part of the world you are talking about depends on which one is smart.

In order to carry out this research published in intelligence magazine from March to April 2011, researchers looked at 64 years IQ score of over 200,000 people in 64 countries. Overall, they have found that the global IQ score has increased by an average 20 percentage points since 1950.

It is noteworthy that the developing countries such as India and China are making maximum profits. These countries have made significant progress in health care and education in the past decades. In contrast, countries like the United States grew much smaller.

This study was aimed at testing the so-called Flynn effect, a long-term rise in IQ score discovered by James Flynn in 1982. New Zealand political scientists have shown that in all countries where data is available IQ has risen 3-4 points every 10 years since 1930. Flynn concluded that the main reason for the increase is an improvement in living standards.

Robin Morris, a co-author of a new research psychiatric professor at King's College London, says: "The main result of this study confirms that the Flynn effect can be observed in many countries and in all ages." It further promoted the influence of flynn in developing countries. "

Although the flyin effect has been observed in many follow-up studies, in the research of the University of Amsterdam in 2013 it was found that the average IQ of Western countries was actually 14 points lower than in the Victorian period. Times. The authors believe that this reduction reflects the fact that women receiving higher education often have few births.

Still, further research is needed to explain why the Flynn effect seems to be amplified in developing countries.

Mr. Morris said at a press conference in January, "This research is currently clearly confirming that the Flynn effect is beyond reasonable doubt and that intelligence testing is done in low-income countries There is. Reason for increase "

For the most part of the 20th century, human wisdom has steadily increased. New Zealand intelligence researcher James Flynn is a person who noticed this trend. According to his survey, our IQ or IQ rose 3 IQ points every 10 years. However, according to a new survey, this "flint effect" is over. From 1962 to 1991, scientists have studied about 750,000 Norwegian men. Their research was published in the June 2018 issue of the National Academy of Sciences. This shows that the Flynn effect lasted until 1975, and the IQ level began to suddenly begin to decline. Steep gradient - 7 IQ points per generation. However, this survey also shows that family intelligence has declined in the same time frame. This indicates that the reason behind the loss of wisdom is not due to a sudden increase in children not smart but due to environmental factors.

If you consider IQ as the most important indicator, be aware that it is increasing worldwide over time. However, this does not explain the entire story. In fact, this is an interesting trend. The IQ of developing countries is rising, but the IQ of developed countries may be slowing down. In 2015, research by King's College London was published in the information magazine, psychologist wanted to know what the image of IQ of the world is. Researchers spent more than 60 years in research. They collected a total of 200,000 IQs from 48 countries. They discovered that the IQ of the world is rising by 20 percentage points since 1950.
