Neither the Origin nor the Destination Decides the Truth

Place these two side by side and a single logical error comes into focus — one the taboo depends on twice over.

Winegard and Carl attack the origin story. The standard indictment holds that racial classification is "ipso facto racist," a product of Enlightenment prejudice and imperial rationalization. Their reply is almost boringly empirical: people classified because the differences are real and predictable — accurate enough that skulls alone sort black and white Americans at 80%. The taxonomy has an ugly pedigree, but a bad motive doesn't make a claim false.

Reich attacks the destination story. The orthodoxy worries that research into population genetics sits on a slippery slope ending in the slave trade, eugenics, and the Holocaust. He shares the fear — and then refuses to let it settle the empirical question, because "it is simply no longer possible to ignore average genetic differences."

What's striking is that these are the same argument aimed at opposite ends of time. One says the idea is contaminated by where it came from; the other says it's dangerous because of where it might lead. Both are versions of the genetic fallacy — appropriately named, given the subject — in which the pedigree or the consequence of a belief is treated as evidence about its truth.

The pairing suggests why the taboo feels so robust: it is defended from both directions at once, so that whichever way you push, you hit a moral wall rather than an evidentiary one. Winegard and Carl clear away the past; Reich clears away the feared future. What's left in the middle is the only question that a scientist can actually answer — not should this be true, or who first said it, but is it.

Notice, too, the asymmetry in tone. Reich, the insider, writes with visible anguish and sympathy for the orthodoxy he's breaking with. The reviewers write with detachment. The insight may be identical, but the cost of stating it is not — which is itself a datum about how politics shapes what science permits itself to say.

Woven from these notes

The orthodoxy maintains that the average genetic differences among people grouped according to today’s racial terms are so trivial when it comes to any meaningful biological traits that those differences can be ignored. The orthodoxy goes further, holding that we should be anxious about any research into genetic differences among populations. The concern is that such research, no matter how well-intentioned, is located on a slippery slope that leads to the kinds of pseudoscientific arguments about biological difference that were used in the past to try to justify the slave trade, the eugenics movement and the Nazis’ murder of six million Jews. I have deep sympathy for the concern that genetic discoveries could be misused to justify racism. But as a geneticist I also know that it is simply no longer possible to ignore average genetic differences among “races.”

The primary reason that natural philosophers began to classify humans into different races is that human populations look different from one another. Their skin colors, hair textures, facial structures, and stature all differ, often in predictable ways. Furthermore, these differences reflect their divergent geographical origins. In fact, researchers can classify human variation by continent quite accurately using only data from the human skull. (They are able to correctly classify human skulls into black and white Americans with about 80% accuracy, using only two variables.) Therefore, despite the common charge that racial classification is ipso facto racist, and that most Enlightenment typologies of human variety were motivated by prejudices and a desire to rationalize imperial domination, ordinary people and Enlightenment philosophers also took to classifying human differences for the mundane reason that such differences actually exist.
