Immigrant intelligence testing

As part of a plan to relieve you from too much reading, here is another video to watch over the weekend, this time about the difficulties of tracking immigrant outcomes and the reluctance in official quarters to examine whether outcomes are largely determined by intelligence.

Differential immigrant performance: A matter of intelligence?

Emil OW Kirkegaard

Many countries now admit large numbers of foreigners into their midst and consequently have large populations of immigrants. When looking at the non-natives as a whole, in most Western countries they underperform relative to the natives. Why is this so? I argue that most research on this topic suffers from multiple problems. First, most research does not distinguish between immigrants at the country of origin level, but rather lumps them into one big category or a few macro-categories, which prevents one from seeing important differences. Second, as a consequence of the first, most research ignores important differences between countries of origin that may be able to explain the differential performance among groups. Third, most research ignores intelligence research, as well as other differential psychology, despite many decades of evidence showing this trait to be important in explaining social inequality. Fourth, most research does not examine the potential explanatory role of Islam as a cultural-religious factor.

I show using a collection of empirical datasets covering many Western countries that when one approaches the question without the above problems one can in fact explain much if not most variation between country of origin groups. I outline limitations with the current body of research and suggest a research program for further research.

    More wanking!!! It seems to be time to review the participation of Thompson in UnzReview?

    Emil O. W. Kirkegaard is a Danish, racist pseudoscientist and paedophilia apologist[1] who founded two “hereditarian” pseudojournals in 2014.
    His journals are essentially platforms for white nationalists and neo-Nazis to publish in the guise of “racial realism” or “human biodiversity”.
    His only actual qualification is a bachelor’s degree in linguistics.

    “Peer review”

    Kirkegaard describes himself as a polymath “scientist”.[2] In reality he has a bachelor’s degree in linguistics; he once described himself as an MA student but either dropped out or was kicked off his course (see below about OKCupid). Most of his research papers are published by himself in his own pseudojournals, Open Behavioral Genetics and Open Differential Psychology. Both journals are not properly peer reviewed; Kirkegaard has invented what he calls “fast open access peer-review” meaning submitted articles can be “reviewed” pre-publication quickly via posting comments on his public forum (OpenPsych). As someone has complained on his forum, this means:
    “”[A]nyone (even a 10 year old) can join a forum, post a comment (as little as one word) and then claim this is counted as peer-review.
    —TombRaider[3]
    Kirkegaard took this peer review as too conflicting with his own views and banned TombRaider, which just reinforces his argument. Kirkegaard later released the user’s IP address. Stay classy.
    Another concern is that although both journals have a few reviewers who are cited on the forum as holding PhD’s, most are in fields not relevant to article submissions. One reviewer (Meng Hu) also left Kirkegaard’s forum after noting the strong bias, i.e. all reviews are made by “hereditarians” with no opposing views:….

    Thanks to you and Emil for providing that. Would it be possible to get a PDF of the slides?

    When I read the summary I was surprised to see no mention of immigrant selectivity (e.g. refugees vs. PhDs, men vs. women, age). Glad to see that was just due to a lack of data and Emil discussed it thoroughly. One thought about that. Would it be possible to try to do inference in the opposite direction? On Chanda Chisala’s blog there is discussion of immigrant selection as a possible causal factor behind his results, but most of it seems to just be reciting priors. I find data like the differences in % with college degrees between British Africans and Africans compelling, but apparently many do not.

    Is it possible to look for outliers with divergent S results between the groups in the source and destination countries and use that as a sign of immigrant selection? That approach would be much better if there are some countries with good data for both source and destination demographics to see if the results are consistent.

    P.S. To hyperbola, extended ad hominems are a really good way to demonstrate you have no substantive argument against the data and results presented.

    Look into the Brain Drain dataset.

    Not so easy to take this into account. But sure, outliers are sign of selection. E.g. look at South Africa. Most likely this is due to SA's being White returnees, not Blacks.

    What "clarification"??? All that is offered is specious meanderings that try to "justify" abuse of children by adults. Seems to fit in with other "ideologies" advanced by sects.

    Maidens and Warriors

    .... A modest Talmudic scholar from Jaffa, I would rise to his defence in the name of our Jewish tradition. Far from being a sinner, Muhammad (peace be upon him) acted according to the letter and the spirit of our holy faith. Biblical Jacob fell in love with Rachel when she was only seven, and brought forth from her a line of saints including Mary, mother of Christ.
    The Talmud stipulates the permitted age of marriage for girls at three years and one day. It brings us a dialogue worthy of Boccaccio that took place in Sepphoris of Galilee. A Roman princess Justine, daughter of Emperor Septimius Severus son of Anthony asked Rabbi Judah the Prince, the greatest spiritual and legal authority of Jews in the post-Biblical period, what is the permitted age of marriage and cohabitation.
    - Three years and one day, - replied the Rabbi.
    - What is the age for childbearing, - persisted the Princess.
    - Nine years [i], - he replied.
    - I was married at six, and gave birth at seven, - she reflected with great regret, - so I wasted in vain three excellent years of my young life.
    Muhammad’s wife, Aisha, wasted six years of her young life, as she was wed at nine. Thus, the Prophet demonstrated great prudence, also in full accordance with our Jewish teachings. Our holy Rabbis permitted very early marriage, but they were not absolutely sure that three-year old girls are sufficiently ripe. They taught: proselytes and paedophiles delay the Coming of the Messiah and of the Kingdom of Heaven.
    Who are the paedophiles in this context, asked the Talmud. They have to be persons of legitimate but objectionable behaviour, and therefore, not the sodomites (as they deserve death by stoning) nor masturbators (they merit watery grave). It is those who marry girls before the nubile age of nine. Thus, the Prophet is above suspicion according to our Jewish law.
    He had a few wives, continue the accusers. Well, the Jewish law permits us to have as many wives as we can get. Nowadays, a Muslim has to limit himself to four wives in this world, but we Jews have no such constrictions.....

    Thanks! I neglected to click More, but it should have been obvious because "Slides" is above the fold.

    One question about slide 11. Any idea what is going on with such a large difference between Serbs in Denmark and Norway? It is interesting how well your regression line matches the obvious y=x prior with the slope decreased a bit by noise reducing the correlation. Is there any chance you could add Serbs to your slide 12 comparison and see how much of an outlier they are there? (we can already see Bosnians showing up which have a discrepancy of about 1.5 vs about 2.5 for Serbs in slide 11)

    Thanks for the Brain Drain data link! Their emigration rate data is perfect for seeing how selective emigration is. For example, in 2010 Nigeria had emigration rates of 0.61% 0.11% 0.56% 12.04% for Total/Low/Medium/High categories (from their methodology note that is primary/secondary/tertiary education). That is such a large difference (~20x H/M and ~100x H/L relative rates!) I think it puts the FUD about selective immigration (well, emigration anyway) not being proven to rest.

    Their brain-drain data link shows total immigrant stock by country (which is perfect for showing how selective immigration is). For example, for Nigerian men in the UK in 2010 we have 54838 9326 3406 42106 for Total/Low/Medium/High categories. Does the Brain Drain data have the source country populations by category and year easily available? (presumably they use it to calculate rates?) The raw data makes it obvious there is selective immigration of Nigerians to the UK, but the Nigerian source population data would help quantify it.

    I can't wait to drop this truth bomb in Chanda Chisala's next thread denying the relevance of selective immigration!

    One possible counterargument is the immigrants are being educated in the receiving country so it is an environmental effect. I believe this argument is inapplicable for the emigration data and for the per year immigration data (right?). Is it applicable to the total immigration data? (i.e. any idea whether they are totaling per year with education measured at transition or surveying the total in a given year?)

    Does Lynn have any information about per country IQ by education level?

    P.S. I wonder why they didn't use Freeze Panes in their Excel files? It makes the data so much easier to read.

    Not only that he quotes meaningless drivel. Since 7 year old girls in those days could not get pregnant (and even though a 9-yo got pregnant in Southern America)) one suspects that the material he is quoting is fiction ... perhaps created by his imagination. It is certainly not worth investigating further.
