I was just cranking up my aged brain to say something the latest IQ findings when latest IQ findings when I found that young Oliver Moody of "The Times" has spared me the trouble. His summary is HERE. There are a few things I would like to add, however.
Perhaps the most interesting fact to emerge is that dumb women having more babies is not a problem. As long as I have been reading the literature on IQ, people have been worried about that. Are all these smart ladies who think no man is good enough for them degrading the average intelligence of the human race? Wonder of wonders, the latest research from Norway was able to rule that out.
Various people have pointed out that the dumbest females for various reasons tend to have NO babies and a majority of high IQ females do have some babies. And it was always hoped that those two effects would cancel one another out. And we now have grounds to believe that exactly that has happened.
A lot of interesting IQ research comes out of Norway and Sweden. The reason is that the Scandinavian countries are very authoritarian, which leads them to keep extensive records about each individual person in their countries. So if you can get access to government data you can base your research on the whole population, not just a sample, with all its attendant doubts and difficulties.
So what we now know with some confidence is that IQ scores rose during the first three quarters of the 20th century but then flattened out before going into a decline. And that could clearly not be due to genetic changes. Evolution doesn't work that fast.
So what WAS going on? There are two major possible explanations: Computer games and education. Blaming computer games has been going on as long as there have been computer games and it is in my mind just snobbery or some such: A convenient whipping boy for all sorts of ills. There is actually a fair bit of evidence that games and internet exposure generally are most likely to be good rather than bad for our brains. (e.g. HERE and HERE and HERE)
Additionally, like Piaget, I have tended to find the kids in my care to be instructive. My son, for instance, could load up and play his favourite computer game when he was two and he plays a lot of games to this day now he is in his 30s and works as an IT professional. And what I saw was that game playing is normally quite social. There will usually be other kids hanging around and talking even with single-user games and some games are quite educational in themselves. My son learnt most of his ancient history from "sims" set in that era. He learnt precious little ancient history at school. So I personally exonerate games from being bad for most people.
So what DID go wrong? Just one thing can account for both the rise and fall in measured IQs: Testing.
During my schooldays in the '50s testing was all the rage. We even did IQ tests at least once a year. And there were heaps of in-school tests. From about grade 3 on, for instance, we would have weekly spelling tests -- in which a kid got a list of 10 words that he had to learn how to spell. Being a born academic, I always got 10 out of 10 and was regularly praised for it. Which was a bit unfair because I put zero work into it. I just had to see a word once to know how to spell it. I still do.
And I think that is one example of a huge difference between then and now. Education used to be COMPETITIVE and "winners" got all the praise. And nobody apologized for that.
It seems to me that there should be no great difficulty in arranging prizes for both ability and effort but the Left have simply closed their eyes to ability
By about 1975 or thereabouts, however, the political Left had got a vice-like grip on education worldwide. Even in chapter 48 of my 1974 book, I noted its encroachment. And Leftists HATE competition because it clashes with their idiotic and counterfactual belief that "All men are equal". To validate that gospel, therefore, all had to have prizes, not just one kid. And if you believe that all men are equal, there would be no point in testing. If the marks come out all the same, what would be the point? But the marks don't come out all the same so to avoid that reality, you just don't do testing if you can avoid it.
The rise in measured IQ scores during the first three quarters of c20 has been the cause of much discussion and the most usual explanation for it is that it was due to the steady expansion of education during that era. More kids gradually got more education as the century wore on. And that was highly relevant to performance on IQ tests. All the testing you did at school made you "test-wise" and that helped you to do well on IQ tests.
You learnt, for instance that ever useful strategy of: "If you don't know, guess". Some guesses will be right and that will raise your overall score. IQ subtests that were not facilitated by testing -- breadth of vocabulary for instance -- showed very little rise in scores. You know what an uncommon word means or you don't. So it was environmental rather than genetic factors that explains the rise in average IQ scores -- known generally as the "Flynn" effect.
But the dominance of Leftism wiped all that. Leftists have a horror of competition so avoided testing at all costs. So an education no longer helped you to do well on IQ tests. And as Leftism gradually tightened its grip, the education effect on IQ scores shrank and shrank. So IQ scores declined gradually over the years.
It's consoling to note however, that the genetic contribution to IQ test score has not changed. We are still as bright as we ever were and what we are genetically is increasingly the sole thing reflected in the IQ test scores
