I’m focusing on my research on IQ for now. I will publish my findings and arguments at the Unz Review.

The question I’m answering is whether the black white IQ gap found on many tests is ultimately caused by racial genes or something else. I believe the question has already been settled by certain global developments which were missed by the IQ community, analytically.

When news reports started discussing how black immigrants and their children were taking most of the black places at elite universities, the question was settled. Yes, it’s no big deal if black immigrants are showing superior intelligence (compared to native blacks) since they could be just highly selected, but immediately they said “and their children”, it was over.

There is no explanation you can give for this trend that is consistent with a racial genetic hypothesis: my articles at Unz.com will show that you can’t explain those three words (“and their children”) under the current hereditarian conclusions on racial intelligence without contradicting either yourself or your premises.

  1. Dear Mr Chisala

    Just a quick note to say how much Ive enjoyed your articles and involvement in the debate in Unz.com.

    Have you any knowledge of the Zimbabwean immigrants to the UK? Of the little I know they seem to have pretty terrible back stories, a tough time with visas and subsequent issue starting careers and yet are pretty successful academically and in the workplace.

  2. I think you have misunderstood the concept of regression to the mean. It does not mean that the children of high achieving blacks will statistically have a mean IQ equal to the overall black mean. What it means is there is a chance that the IQ will regress towards the mean. But if selection for intelligence continues in the subsequent generation then there will be statistically higher IQs again among those children. In the case of African immigrants, they are often drawn form higher class Africans who may have been selected for intelligence and achievement already over many generations before even reaching America. If regression to the precise mean was literally true then there would be no such thing as dairy cows or champion breed race horses. In fact there would be no such thing as evolution via natural selection at all.

    1. I obviously haven’t misunderstood the very simple concept of “regression to the mean.” At no point have I said that the children of high achieving blacks should be “equal” to the overall black mean (that’s not what regressing “to” means). I said it should regress TO that mean. Or, TOWARD that (lower) mean. The whole point is that there is NO evidence suggesting that the children of high achieving black IMMIGRANTS have IQs that have regressed TO a lower mean (or regressed MORE) than that of the children of similarly high achieving whites, as racial hereditarians predict.

      1. I’m really curious about this as well. As a practicing data scientist I’m quite familiar with the idea of random processes regressing towards the mean of some likelihood distribution, but the intelligence of a child is hardly random. Is it not a function of the genes of the child’s parents, and if those parents are both highly intelligent, would that not suggest high intelligence on the part of the child inheriting those genes? After all, we don’t draw our genes from some random pool of genes common to our race, we get them from our parents. As such, why would you expect regression to the mean of a racial intelligence distribution to occur? What’s the suggested mechanism (genetic or environmental) by which you’d expect that regression to occur? I’d think that children would tend to have intelligence that was roughly equivalent to the intelligence of his/her parents, ceteris paribus, not the average intelligence of his/her racial group (or any other group you’d like to put them in, other than other children of smart parents). Happy to read any relevant papers you’d like to cite. Thanks.
