Humanity grows dull: the researchers note a gradual decrease in the level of intelligence in humans

Norwegian scientists say that humanity is rapidly becomes stupid. Brief excerpts from the findings of research published edition MedicalXpress. Full results of the Norwegian research efforts published in the journal Proceedings of the National Academy of Sciences. However, many do not agree with the conclusions of the Norwegians, pointing to the limitations of the sample and, therefore, the inability to use the results for all the inhabitants of the Earth.

Humanity grows dull: the researchers note a gradual decrease in the level of intelligence in humans

The thesis of a gradual decrease in the level of human intelligence is not new. Despite the constant accumulation of new knowledge civilization, on individuals do not become more intellectually developed. Some scientists even believe that modern man plays on a number of indicators of mental Cro-Magnons. This is attributed to the fact that the inhabitants of the earth of the XXI century will not have to fight every day for their survival, which largely eliminates the evolutionary role of natural selection.

Interestingly, however, different. More and more often hear the statement that mankind has "rapidly becomes stupid." And it once again confirmed the Norwegian scientists from the Center for Economic Research Ragnar Frisch. The material for their study is based on IQ test results of the Norwegians, to enlist in the 1970-2009 years. Total researchers used the results of 730 000 tests. According to these results, in one generation, intelligence dropped by an average of seven points, which, of course, a very serious figure. As possible reasons, scientists are considering environmental issues, as well as lifestyle changes. This, in particular, comes to computerization. Conclusions Norwegian scientists already subject to criticism, pointing out the limitations of the sample and, therefore, they can not be used in respect of the whole of humanity. However, similar conclusions came earlier and another group of scientists. Then the researchers compared the level of education of modern people and the inhabitants of the Victorian era from 1837 to 1901. The results showed that when the man was more advanced and inventive.

Program analyzing the psychophysical data showed that the rate of reaction of the men in 1889 was equal to 183 milliseconds, while today the figure is 253 milliseconds. In the case of female figures were 188 and 261 milliseconds, respectively. Experts also found that every decade IQ dropped by 1, 23 points and a half century, the decline was 14 points. According to experts, at such a dynamic person may eventually drop to the level of a developed ape.
