A Norwegian study published Monday found a seven-point dip in IQ test scores per generation among men born from 1962 to 1991. The results suggest a reversal in the Flynn effect, an observed increase in IQ scores throughout the 20th century in developed countries.
Coverage from The Week adds:
The reasons for the Flynn effect and its apparent reversal are disputed. "Scientists have put the rise in IQ down to better teaching, nutrition, healthcare and even artificial lighting," says The Times.
But "it is also possible that the nature of intelligence is changing in the digital age and cannot be captured with traditional IQ tests", adds the newspaper.
"Take 14-year-olds in Britain. What 25% could do back in 1994, now only 5% can do," Shayer added, citing maths and science tests.
More from The Daily Mail:
Two British studies suggested that the fall was between 2.5 and 4.3 points every ten years.
But due to limited research, their results were not widely accepted.
In the latest study Ole Rogeburg and Bernt Bratsberg, of the Ragnar Frisch Centre for Economic Research in Oslo, found that Norwegian men's IQs are lower than the scores of their fathers when they were the same age.
The pair analysed the scores from a standard IQ test of over 730,000 men – who reported for national service between 1970 and 2009.

Feminism. Schools have changed from establishments of learning to childcare, where young minds go to learn not to ever make anyone feel uncomfortable.

You jest, or troll - but there may in fact be truth in it.
If intelligence is hereditary (it is, at least partly) then any system that disincentivizes breeding in the more intelligent, or incentivizes it in the less intelligent _will_ result in a population decline in intelligence. If socioeconomic success is linked to intelligence (rather than more directly inherited as "class"), then that means that disincentivizing the rich(er) from breeding, or incentivizing the poor, will have the same result.
It is possible that this decline is only "in developed countries" - not clear if the trend doesn't exist world wide or if they just haven't done the research.
Now, "in developed countries" since the 2nd world war, and particularly since the 60s, there have been significant social changes (more or less your "Feminism"):
* Reliable birth control, giving women a choice when/whether to have children
* More years spent in education on average (for men and women)
* Large increase in working women (possibly resulting from above or possibly coincident with)
* Resulting increase in housing costs - because prices are now typically based on two incomes and that is what you are competing with when buying
* Resulting increase in people delaying having children until they are financially ready, and having fewer (having left it later)
[There is also less pressure to have children to look after you in your old age as this social responsibility has shifted from individual/family to "society"]
BUT (and this is key) all this is in the higher socioeconomic groups, at the other end of things the rise of the welfare state means that young women in lower socioeconomic groups not only have less to lose from having children but may actually gain (both financially from benefits and in terms of larger social housing). There are those who will have children purely to get the benefit money - I have seen them and heard their views first hand.
SO, we are both disincentivizing the rich from breeding, and incentivizing the poor to breed, and the next generation is dumber. Quelle surprise.

Already proven false many times, I guess this article is just another dog whistle for you Eugenics fans.
Don't worry though, you're totally 70 years too late to be an actual Nazi.

The vast, vast majority of schools were never establishments of learning, but rote memorization factories.
