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.

Means very little, other than you can do what the instructors want you to do to get the best scores - which (at the highest levels) is as much a social skill as it is correlated with mastery of the subject of the class/course. What I'm saying here is that teachers/professors are human, and while _on average_ they tend to correlate grades with mastery of the subject, there is a great deal of human noise (prejudices, personalities, randomness) in the score - and that shows up heavily when you hit the top of the scale.
I have found that depends almost entirely upon the career pursued. Again, in the middle, on average, drones being processed through HR departments for placement in the average job pool, yes... IQ has a strong correlation, but even more than school, there's tremendous human noise in the process - luck/timing of placements, who you happened to get as a boss, what your group/department/company/industry experienced in the broader market, all have a very strong bearing on success. Then there are entire fields (Sales, especially Real Estate Sales for one) where intelligence seems to be a neutral if not negative asset due to the social aspects of the jobs.
If you're calling the top and bottom ~10% the "far edges," and 20% the "tiny minority" for highly successful low IQs and lowly successful high IQs, then, maybe we're in agreement.

No. You forget that the average school is abysmal. On average, they tend to correlate grades with one's ability to rote memorize information about the subject and spew it back on tests and homework assignments.
