We're All Getting Dumber, Says Science (fastcompany.com)
dryriver shares a report from Fast Company: Researchers at Norway's Ragnar Frisch Center for Economic Research now have scientific proof of something we've long suspected -- we're all getting dumber. In their paper, "Flynn effect and its reversal are both environmentally caused," which was published in Proceedings of the National Academy of Sciences, Bernt Bratsberg and Ole Rogeberg report that IQ scores have been steadily dropping since the 1970s.
The study consisted of analyzing 730,000 IQ test results gleaned from young men entering Norway's compulsory military service from 1970 to 2009. They found that scores declined by an average of seven points per generation, a reversal of the so-called "Flynn effect" where IQ was seen to be rising during the first part of the 20th century. The decline may be due to environmental factors, but because the researchers couldn't find consistent trends among families, Bratsberg and Rogeberg discounted factors like parental education, family size, increased immigration, and genetics as significant causes.

.... sounds exactly like one of those results that would vanish in a puff of annoyingly-irreproducible logic if anyone actually tried to replicate the underlying studies.
You know, like 90% of all other published research in the psychological sciences.
Unless there is something VERY special about Norway, a wide-spread trend that cannot be attributed to education, gender, religion, or other environmental factor has pretty good predictive qualities, since the sample size is large, and unbiased (Only males tested most likely, but the service is compulsory, not voluntary. That means *All male citizens*, not "Those that show up to the recruitment office".
It means the sample is very very large, and that the trend is pervasive and wide-spread is pretty interesting.
To rule out that something is indeed special about Norway, it needs to be replicated with data from other geographic regions-- but so far it is a pretty compelling argument using raw statistics.
Getting a little bored with the "Science" Says claims, like there's some governing body of authorised scientists that make things official.
I've started replacing that term in my mind with "some random dude claims".
Never happened. True story.
I still contend that computer usage makes smart people smarter and dumb people dumber (yet the now-dumber people think they're smarter).
Problem with that is that if the recruiters want you to serve anyway you are going to be put in cannon fodder training.
It is much better to do well on the IQ and perception tests and fake being physically too weak to serve.
Having an inconvenient allergy or two might be useful too.
That way, if you have to serve you will probably get a position as a signalist or get some command training.
