The Same Anti-Prejudice Banner Waving Over Opposite Facts

Notice that Lewontin and the Winegard–Carl review are filed under the identical rubrics — "Science Against Prejudice" and "The Biological Reality of Race" — yet they make flatly contradictory empirical claims. Lewontin insists racial classification is "of virtually no genetic or taxonomic significance." Winegard and Carl reply, almost point-for-point, that forensic anthropologists sort skulls into black and white Americans at ~80% accuracy from two variables. These cannot both be true as taxonomy. One of them is smuggling a moral verdict into a factual slot.

And Lewontin's passage shows the seam: it slides from an empirical premise (within-group variation exceeds between-group) straight to a normative conclusion ("positively destructive... no justification can be offered for its continuance"). The second sentence does not follow from the first — statistical structure doesn't tell you whether a classification is useful, only how it's distributed. The taxonomic claim is doing the work the moral claim wants done.

This is exactly the pathology the Carleton Coon anecdote diagnoses. The AAA condemned Putnam's book with one member having read it, because everyone knew in advance what the verdict should be. Coon's raised-hands question — who has actually examined the thing? — is the question Winegard and Carl are, in effect, raising against Lewontin: has anyone checked whether the classification works before declaring it meaningless?

The deepest irony sits with Boas. Degler frames Boas's move as the radical one — replacing biology with history as the explanation of difference. But radicalism became orthodoxy, and orthodoxy stopped being tested. The Coon note reminds us that "Science Against Prejudice" started as an evidentiary revolt against a comfortable consensus; Lewontin's rhetoric shows the same banner, a generation later, being used to shut down inquiry rather than open it. The tag that once meant "look harder at the evidence" quietly came to mean "you already know the answer." The virtue curdled into precisely the vice it was invented to correct: condemnation without examination.

Woven from these notes

Boas’s rejection of the traditional view was truly radical; it simply denied the existence of any significant innate differences between savage, colored people and civilized, white people. The differences in physical appearance, in short, did not lead to any significant difference in mental or social function. That there were observable social differences was undeniable, but the explanation for those differences. Boas maintained, was that they were the product of different histories, not different biological experiences.

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.

Carleton Coon was one of the greatest anthropologists of the 20th century and a champion of the study of racial differences. In 1961 he was elected president of the American Anthropological Association. It was during this year that Carleton Putnam's infamous book Race and Reason came out. Putnam's book argued that there were significant differences between the races and that this had important political implications. A few anthropologists became upset when they saw the book gain popularity and wanted the AAA to intervene. But they knew that Coon supported the book and that, as a result, having the AAA take action against it would be difficult. So they organized a secret meeting behind Coon's back in order to issue a statement denouncing Putnam's work. Coon found out about the meeting and went to stop it. Upon entering the meeting Coon asked all the association members who had actually read Putnam's book to raise their hands. Only one rose. He then asked for the hands of everyone that had even heard of the book prior to that meeting. Only a few hands rose. None the less, the statement against the book passed. Coon, disgusted by the actions of his peers, resigned from the AAA (1). This incident stands out in the history of science as a particularly clear example of scientists not living up to what people expect of them. People often take what scientists say for granted. They trust that scientists have looked at the evidence rationally and are giving the public as accurate an account of all the relevant facts as they can. When explaining science to laypeople researchers are expected to only make authoritative statements on topics they are knowledgeable of, to not lie about scientific evidence, and to not omit obviously relevant facts. People trust scientists to do these things and so feel comfortable taking what they tell them for granted. (See
It is clear that our perception of relatively large differences between human races and subgroups, as compared to the variation within these groups, is indeed a biased perception and that, based on randomly chosen genetic differences, human races and populations are remarkably similar to each other, with the largest part by far of human variation being accounted for by the differences between individuals. Human racial classification is of no social value and is positively destructive of social and human relations. Since such racial classification is now seen to be of virtually no genetic or taxonomic significance either, no justification can be offered for its continuance.
