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.

    IQ tests are some of the most deeply studied things in psychology, they're very close to being culturally indifferent. However, if a culture - by accident of design - breeds a population with non-critical minds, and unwilligness to think analytically, then it will of course return a lower median IQ for that population.

    Which mean that the IQ test doesn't test your intelligence, but rather your ability to employ critical and/or analytical thinking. Which certainly is one aspect of intelligence, but not the only one. Indeed, it is exactly the other aspects of intelligence that make AI a hard problem.

      Seems to be the only aspect.

      There's a list of wishful thinking at

      https://en.wikipedia.org/wiki/Outline_of_human_intelligence [wikipedia.org]

      But that is hard to take seriously when it contains "cultural yes man" measures like "Moral intelligence" or "Spiritual intelligence". Even worse when you research stuff that doesn't sound too ridiculous, like spatial intelligence, google found me a study (Swanson '96) along the lines of below 100 IQ people, verbal IQ and spatial IQ are essentially uncorrelated.

      Something like electromagnetic field theory is one "thing" with a couple aspects. You can't move an electric charge without making a magnetic field and you can't wiggle a magnetic field without inducing an electric field and so forth. However, no matter how sexy you paint the experimental apparatus in purple polka dots, the E+M fields shouldn't change (other than at the wavelength of violet light, LOL). Likewise it seems intelligence IS reasoning, no matter how much some folks would like to include spiritualism or sophistry.

              Actually, IQ is an excellent predictor of success ON AVERAGE. Extremely well correlated. There are always outliers.

              success requires an IQ score of perhaps 70

              84, according to the military. That's the minimum they will accept, because over the years they have determined that anyone with less basically cannot be trained for any job.

              And that's pretty scary. Probably the scariest statistic of our time. It comes out to about 10% of the people are below 84 IQ, and they cannot do any job in the modern world. The menial tasks they have been able to do are by large measure going away.

                    I would agree with the GP with regards to those jobs not having to go away. A manufacturing company I used to work for many years ago was next door to a sheltered workshop - basically somewhere to house intellectally challenged people while finding them something to do.
                    We would occasionally have some simple repetitive task that needed to be done thousands of times, and they would get the job. One carer would come in with them. We would explain to him/her the job, and he/she would explain it to them, and supervise while they did it. They were the happiest, most diligent and enthusiastic people I ever worked with. They loved feeling useful, even if it was just assembling boxes.
                    As a society we have lost sight of that. It should not be just about if a robot can do it better and faster, but what is better for people.

            Research has shown that average IQ of race drivers is 130-135. Other research has shown that the primary burden on a race driver is the enormous flow of information they have to process. I assume from this that IQ does correlate with mental bandwidth, hence the high IQs.

            That might speak more to the brutally competitive nature of human society. There are many negative feedback loops that widen the gap between someone with 100 IQ and someone with 120. It begins in the school system where if a student falls behind in 2nd grade and does not receive remedial help then that trend will often get worse and their future prospects will go along with it. That doesn't mean the person isn't capable of holding a normal job and be a successful contributing member of society.

            This entire thread is so full of blind assumptions based on how society IS that most people can't imagine what society COULD be.

            Once we automate away all the menial jobs we'll get a society with the rich smart people on top and the dumb people on some sort of nightmarish welfare which will lead to revolution. That is with our current system anyway.

            Even if you went the eugenics route that so many users on here obviously dream of you will likely cause other problems. Smart people tend to be more prone to mental disorders and delusions of grandeur (eugenics) which could lead us into mass sterility or even worse genetically engineered problems. Hell, even without those you'd end up in some cutthroat society where the best aspects of humanity such as compassion and courage get trampled into dust.

            The self-styled bigoted geniuses around here are too smart for their own good. They hide behind logic, reason, and numbers; but forget that the numbers are the result of a complex system that no human can completely understand.

              It's not human society, it's all of nature. The distribution you're describing, where small differences in ability, first-mover status, resource access or pure luck lead to huge differences in productivity was first discovered in pea plants. I believe it's referred to as the pareto principle or pareto distribution. Human society actually strives to mitigate those effects of nature, NOT to exacerbate it.

              Your premise is false. These are natural outcomes. Of course we want to create a society that works for everyone, and helps those that are weak or vulnerable. But, in western society at least, we also want to ensure that people that are more capable and productive are rewarded more for their efforts. That's fair and helps everyone. We don't make rock stars out of people with no musical talent (usually), and we don't want people that can't do simple math writing computer software we rely on for critical tasks. Sure, there's corruption that harms those outcomes that we value, and corruption is something we should fight against. But for the most part we want the most capable people to be the most valued.

            success in school

            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.

            and in future career endeavors

            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.

            except the tiny minority and the far edges of the bell curve.

            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.

              and while _on average_ they tend to correlate grades with mastery of the subject

              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.

            And what does that have to do with intelligence? Stop relying on faulty social 'science'; it rots your brain.

      What decade are you living in? You're repeating the complaints from the 60s and 70s, when IQ tests were plagued with lots of language-related question, that have since been purged.

    Which IQ tests? They aren't all the same, and they don't all measure the same thing (though there normally is a quite strong correlation). It's also quite clear that the extent to which they are culturally indifferent is limited...though again it's different for different IQ tests. To take an extreme case, the early IQ tests were given to people who didn't understand English, and they made truly wretched scores for quite understandable reasons. But the *tests* were the same ones that were standardized at Stanford. Now one could say that this example was laughably extreme, but the results were used to justify laws, so some people were taking them seriously, if not honestly (and that can't be proven). And it implies that one can expect the same effects to a lesser extent in cases that are less extreme. If you don't think that does apply, I'd like to hear why not.

      I've been thinking that there's a catch 22 at work here: the tests in the 1970s sucked, so... if you continue to use them today, you're using sucky tests.

      However, if you use the improved tests today, then you're changing your testing method and comparing apples to oranges.

    IQ tests are some of the most deeply studied things in psychology

    Which is a social science filled with absolute garbage. IQ is correlated with several things that people commonly deem significant, but it's never been rigorously proven that it actually measures intelligence. We don't even truly understand intelligence, so good luck measuring it as of yet.

      Well that's easily fixed. You simply define intelligence as that which is measured by IQ tests.
