David Dobbs reviews ‘A Troublesome Inheritance’ in the NY Times. Once again, Nicholas Wade falls flat.
If Wade could point to genes that give races distinctive social behaviors, we might overlook such shortcomings. But he cannot.
He tries. He tells, for instance, of specific gene variants that reputedly create less trust and more violence in African-Americans and, he says, explain their resistance to modern economic institutions and practices. Alas, the scientific literature he draws on is so uneven and disputed that many geneticists dismiss it outright. Wade also cites a 2008 paper that analyzed the genomes of almost 1,000 people from 51 populations around the globe. That paper found that people from different regions do indeed tend to have distinctive genomes. But Wade errs in saying the paper supports his idea that genetic selection has created races with particular social inclinations.
To begin with, the 2008 study mentions nothing about race. It merely establishes that many of the slight differences between human genomes cluster by geography at many scales, including continents, and that genomes from any given location will most likely be similar, just as two people from a particular place will most likely speak with similar accents.
Second, and far more serious, the paper’s authors specifically state that while selection may sometimes create genetic differences between populations, they saw little evidence that selection shaped the small genetic differences they found. In fact, they say the differences can be largely explained by “random drift” — arbitrary changes in genes having little to no effect on people’s biology or behavior. All of this directly contradicts Wade’s argument. Yet he baldly claims the study as support.
And he does this sort of thing repeatedly: He constantly gathers up long shots, speculations and spurious claims, then declares they add up to substantiate his case.
You know, mangling peer-reviewed articles and throwing a prejudicial slant on science that ignores the totality of the evidence is what creationists do, but I’m sure Wade’s HBD supporters will be along shortly to accuse Dobbs of being a ‘new creationist’.
Check out Dobbs’ blog post on the article. Very first comments are tiresome cliches from the same usual bores who show up to defend racism, flinging around accusations of “New Creationism” and “Cultural Marxism”. Prediction fulfilled.
