The British "Times" recently published an article saying that a latest study found that the people with the highest IQs in the world are distributed in China, Singapore, South Korea and Japan. In addition, the quality of a country's economic development has a great relationship with the IQ of its citizens.

This study was jointly conducted by Richard Linn, professor of psychology at the University of Ulster in Northern Ireland, UK, and Tatou van Hanain, professor of political science at Tempel University in Finland. They arrived at this result by comparing the gross national product and national IQ of 60 economies around the world.

The IQ termed in this study originated in France in 1904. This value is not used to test the amount of knowledge, but to judge the ability of the brain to work. The average person's IQ is between 85 and 115, and the average human IQ is 100.

Research shows that the people with the highest IQs in the world are the nationals of China, Singapore, South Korea and Japan, with their average IQs as high as 105.

This study also believes that the next smartest people are distributed in Europe, North America, Australia and New Zealand, and their average IQ is 100. The average IQ of people in South Asia, West Asia, North Africa and most Latin American countries is 85. The regions with the lowest average IQ are sub-Saharan Africa and the Caribbean, where the average IQ is 70.

After comparing the relationship between economic conditions and IQ in various places, researchers believe that the impact of national IQ on economic development accounts for at least 58%. For citizens with an IQ above 70, for every 1 point increase in IQ, per capita GDP can increase by 500 pounds. Because people with high IQs can master more complex manufacturing processes and service skills and promote them globally. At the same time, people with high IQs can develop more effective public service facilities such as transportation and telecommunications. Moreover, leaders who emerge from groups with higher IQs tend to be more capable.

Although the main factor that determines IQ is heredity, the objective environment can also greatly affect the development of IQ. In developed countries, per capita IQ can increase by 25 points in one generation. Linn believes that the quality of nutritional status has a significant effect on the level of IQ. Even in developed countries, there are cases where poor nutrition affects IQ. In addition, education also plays a vital role in people's IQ.
