It took many decades, and scientists from around the world continue to conduct research in order to understand whether there are differences in intelligence between Asians, blacks, people and Caucasian race. The theory of human races highlights from 3 to 15 races, each of which is formed on its territory and has a number of distinctive features. We take as a basis the three races: Caucasoid ("white" people), Mongoloid (Asians) and Negroid (black). Philippe Rushton and Arthur Jensen, the staff of the two universities of Western Ontario and Berkeley, for several decades engaged in research related to the identification of how different levels of IQ in people from Africa, Asia, Europe, barely, brought together the knowledge gained in a separate work. If we believe these results, the level of intelligence depends on the color of the skin: for example, Asians have the highest average IQ - 106 in Caucasians - 100, and the average level of intelligence in blacks - only 85 (for residents of the United States) and 70 (in Africa). The study is based on the statistics for the last 90 years, which affects the period of the First World War to the large-scale testing of 6 million Americans in 2001.
And although it is known that the level of intelligence depends not only on the genetic heritage, but also on social factors, quality of life and education, yet Rushton and Jensen reported that the difference in IQ between, for example, negroid and Asians already apparent at the age of 3 years despite the fact that parents have exactly the same level of education. IQ tests are different (you yourself can pass IQ test for free and without registration ), they estimate the total IQ, verbal, math skills, spatial thinking. So, the differences between the races is most clearly seen when trying to assess the overall level of intelligence. On this basis, we can assume that even if the averaged lower IQ black people at the proper level of education are better able to cope, for example, with mathematical problems than Caucasians. The study also showed that the difference in intelligence remains even in the case of interracial adoption. And among the Negroid observed this trend: the darker the skin tone, the lower the IQ. Knowing the average IQ for their race, try to pass the IQ test for free without prescription and determine your IQ.
Over 90 years accumulated quite a lot of statistical regularities in favor of the theory of the difference in IQ among different races. However, in the modern world with its policy of eliminating racial segregation should primarily rely on the fact that each person is a unique individual, with its own characteristics, abilities, strengths and weaknesses, and not just a representative of his race.
