A new study, conducted by Norwegian scientists, shows that IQ scores of today’s young people are in decline, putting an end to the post-war trend of rising intelligence.  After the Second World War young people’s IQs were steadily rising. It was dubbed the Flynn effect after New Zealand intelligence researcher James Flynn. This phenomenon saw average IQ scores rise about three points per decade. But researches from the Ragnar Frisch Centre for Economic Research in Oslo say the Flynn effect is

now past its peak. In a paper, published in the PNAS journal, Norwegian scientists Ole Rogeberg and Bernt Bratsberg analyzed the data from standardized IQ tests of about 730,000 men, born between 1962 and 1991, who underwent mandatory IQ tests to join the national service. The study revealed that the IQ points of those tested peaked among those born in 1975, while people born in 1991 scored five points lower. According to the scientists, this shift could be due to many factors, including the way children are brought up and educated. CONTINUE
