Alt Left: Repost: Flynn Effect in North Africans/Turks Migrated To West Europe

From an article by Philippe Rushton, hereditarian, a revelation about yet another instance of skyrocketing IQ increases in the second generation born in the West after migrating from the less developed areas.

Previously, we noted that the children Jamaican immigrants to the UK (IQ = 71) have IQ’s of 85-86, typically within a single generation. That is a gain of 14.5 IQ points merely by being raised in the West. Hereditarians have offered many rationales for this. The usual is that the Jamaican immigrants were already very bright anyway (as we will see with Moroccans and Turks in Netherlands, this is not true).

Another is that Jamaicans in the UK are very heavily bred in with Whites to the point where they may be only 1/2 White. This is not true – UK Jamaicans are only 12% White (Jamaicans in Jamaica are 9% White).

The children of Indian and Pakistani immigrants to the UK (IQ = 81.5) have IQ’s ranging from 92 (Rushton) to 96 (a figure I prefer). Call it 94. This is a gain of 12.5 IQ points merely by being raised in the West. The counter-argument here once again is that this group is self-selected.

Taken together, the children of Jamaican and East Indian immigrants see rises of 13.5 IQ points merely by being raised in the West. It is true that beyond the initial jump, we are not seeing more rises.

However, a strong initial jump is perfectly consonant with a hyperinjection of massive intellectual stimulation, good health care, proper diet, etc. This is probably all related to a higher standard of living. Higher standards of living seem to be somehow translating into long-term rises in IQ. The mechanisms can be debated, and we have done so on this blog.

Education, a massively-stimulating environment (computers, cell phones, TV, movies), proper nutrition, good health care, and myriad other things have been suggested, but the mechanisms for the rises are still somewhat mysterious.

Now, via Rushton, we have yet more evidence of a Flynn Effect in immigrants to the West. First generation Moroccans and Turks in Netherlands had IQ’s of 81. This is low. The Moroccan norm IQ is 84 and the Turkish norm IQ is 90. So, contrary to the argument that only the very brightest immigrants are going to the West, it seems instead that the less bright immigrants are arriving instead.

The second generation has IQ’s of 89. 89 is around the Turkish average, but it is 5 points above the Moroccan average. At any rate, it shows a Flynn gain of 8 points simply by migrating to the West. Rushton tries to explain this away somehow, but he doesn’t do a good job of it.

The evidence for massive IQ gains in second generation immigrants to the West is now becoming overwhelming and it is going to be harder and harder for hereditarians to explain this stuff away.

Comparison of 1st and 2nd generation immigrants to the West and the resulting Flynn Effect gains, apparently solely by being born and raised in the West. The common factor behind rising IQ’s in the West may be related to rising standards of living.

                   1st     2nd     Gain
UK Jamaicans       71      85.5    14.5
UK East Indians    81.5    94      12.5
ND Moroccans/Turks 81      88      7
Average            78      89      11.5

  1. All very interesting.

    But has this been corroborated by the digit span test in pre-school age children?

    One reason is cultural. An IQ test may make more sense to Western treated people versus those in Africa or Turkey. So no real IQ gains at all. IQ deniers love to claim there is cultural bias in these tests. Maybe there is.

    Another reason is environmental: better nutrition and health care leads to organic gains in IQ as you pointed out in the iodine deficiency article above.

    Finally, are these increases even meaningful? That is, are they committing less crime and making more income compared to the people in the countries they emigrated from and instead comparable to Whites in those countries to which they immigrated?

    1. “But has this been corroborated by the digit span test in pre-school age children?”

      All of the hereditarians agree that the increases are real. Their counterargument is that there were no gains due to selective immigration. That is, the Jamaicans who immigrated already had 86 IQ’s, so there was no gain. No one has tested the parents, so we do not know if this is true. Flynn said he did not think that selective immigration could have raised the scores more than a few points. But it remains an open debate. I think selective immigration is bunk, but neither I nor the supporters of the theory can prove or disprove it.

      For the Moroccans in Western Europe, hereditarian Philippe Rushton said that there was a gain, but it was only eight points, so it’s no big deal.

      My argument would be that I am worried that the Jamaicans, Turks, and Moroccans in Western Europe have ceilinged out. That is, this is as high as the rises will go. The Jamaicans will stall at 86, which is the same IQ as US Blacks, and look at all the problems we have with them. Granted, the UK would rather have Jamaicans with 86 IQ than with 71, but still…

      The Moroccans may have ceilinged out at 89. Which is ok and is nearly enough to sustain an advanced civilization (90 is required), but Hispanics in the US have IQ’s of 90, and look at all the problems we have with that group. Sure Moroccans with IQ’s of 89 are better than those with 81, but they’re still a problem in the Netherlands, guarantee it.

      “One reason is cultural. An IQ test may make more sense to Western treated people versus those in Africa or Turkey. So no real IQ gains at all. IQ deniers love to claim there is cultural bias in these tests. Maybe there is.”

      “Finally, are these increases even meaningful? That is, are they committing less crime and making more income compared to the people in the countries they emigrated from and instead comparable to Whites in those countries to which they immigrated?”

      I don’t know. They’re doing better in school, I will give you that much. They’re still a problem. Jamaicans commit a lot of crime in the UK, and Turks and Moroccans commit a lot of crime in Germany and the Netherlands.

      Another reason is environmental: better nutrition and health care leads to organic gains in IQ as you pointed out in the iodine deficiency article above.

      This may have something to do with it. Or perhaps growing up in an advanced technological society simply raises IQ. And “wealth” may have something to do with it. In fact, this seems to be what is driving the gains.

      None of the hereditarians believe in cultural bias. I was an acquaintance of James Flynn, one of the top researchers in the world on human intelligence. He told me he didn’t believe in the cultural bias argument. Furthermore, all of the environmentalists now agree that the tests are not biased. For years they argued that they were biased, but they caved a while ago.

    1. Are you in school? Best one you can take is one you can get for free at your school. Do you live in the US?
