IQ test results show that people are getting dumber
Ogolny people’s intelligence quotient has been steadily declining for several decades reversing an earlier trend thatory showed that people were getting smarter. This is according to research by scientistsow from the Ragnar Frisch Center for Economic Research in Norway.
Bernt Bratsberg and Ole Rogeberg published the results of their study in the „Proceedings of the National Academy of Science”. According to them, the results of testow on intelligence has been slowly declining since the 1970s. The researchers also describe in the publication several possible explanations for this phenomenon.
According to previous studies, in the first half of the last century, the results of the testow on intelligence were getting better, people were smarter. At least that’s what the rising intelligence quotient indicated – trend, whichory has been called the Flynn effect.
It was proposed ror different theories to explain this apparent brightening of the human mind, such as better nutrition, better health care, education, etc. But now, according to scientistsow of Norway, this trend has ended. Instead of getting smarter, people are getting dumber.
The Norwegian researchers analyzed the results of the testoIn the IQ of young men entering compulsory service in the armed forces from 1970-2009. A total of 730,000 testow on intelligence. After analyzing the data, the researchers found that scores fell by an average of seven pointsow per generation, which is a clear reversal of theoprice the resultow testoin the last few decades.
Researchers have also discovered some rodifferences between the groups, suggesting that some of the worse results of theow testow may be due to a factoroIn environmental. They can also result from lifestyle changes, such as changes in the education system. On top of that, scientists point to the increasingly present technology in our lives. The researchers notedociliated that children are reading less and less and spending more time on video games.
OgoA lne drop in intelligence levels was also noted by other researchers. Researchers from the UK found that the results of the testoin IQ have declined by 2.5 to 4.3 points for each decade since about the end of World War II.
