CBS SACRAMENTO – June 16, 2018: The article sourced from CNN, highlights that IQ scores have been steadily falling for the past few decades, and environmental factors are to blame, according to a new study.
The research suggests that genes aren’t what’s driving the decline in IQ scores, according to the study, published Monday.

Norwegian researchers analyzed the IQ scores of Norwegian men born between 1962 and 1991 and found that scores increased by almost 3 percentage points each decade for those born between 1962 to 1975 — but then saw a steady decline among those born after 1975.
Similar studies have also been done in Denmark, Britain, France, the Netherlands, Finland and Estonia demonstrating a similar downward trend in IQ scores, said Ole Rogeberg, a senior research fellow at the Ragnar Frisch Center for Economic Research in Norway and co-author of the new study.
Flynn effect and its reversal are both environmentally caused
PNAS – June 16, 2018: Population intelligence quotients increased throughout the 20th century—a phenomenon known as the Flynn effect—although recent years have seen a slowdown or reversal of this trend in several countries. To distinguish between the large set of proposed explanations, we categorize hypothesized causal factors by whether they accommodate the existence of within-family Flynn effects.
