IQ scores are falling and have been for decades, researchers say
Posted: Jun 13, 2018



IQ scores have been steadily falling for the last few decades, and
environmental factors are to blame, a new study says.
The researchers suggest that environmental factors -- not genes -- are
driving the decline in IQ scores, according to the study published

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 in Denmark, Britain, France, the Netherlands, Finland,
and Estonia, have demonstrated 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 study.

"The causes in IQ increases over time and now the decline is due to
environmental factors," said Rogeburg who believes the change is not
due to genetics. "It's something to do with the environment because
we're seeing the same differences within families," he said.

These environmental factors could include changes in the education
system and media environment, nutrition, reading less and being online
more, said Rogeberg.

The obvious solution is that the internet generation say "Who needs
IQ? Just Google it." Or, alternatively, peer pressure directs people
to conform to their friends on Facebook and spend their time on social
