How a Scientific Victory Hardens into an Orthodoxy That Stops Reading

Degler and Wade describe the exact same historical fact — Boas's overwhelming influence on American thinking about race — and cast it in opposite moral registers. For Degler, Boas waged a heroic "assault" against segregation and eugenics through the concept of culture. For Wade, the same campaign installed a "doctrine" whose conclusions were fixed in advance: genetics cannot be the answer, therefore culture must be. Neither disputes what happened. They dispute whether it was science correcting prejudice or politics capturing science.

The Carleton Coon anecdote suggests these aren't alternatives but stages. A view that begins as an evidence-based corrective (Degler's story) can win so completely that it stops needing evidence to enforce itself (Wade's story). The AAA members who denounced Putnam's book without reading it — most hadn't even heard of it — weren't weighing arguments; they were performing membership in a settled consensus. That is what victory looks like from the inside: the question feels so closed that examining a dissenting book seems not merely unnecessary but disreputable. The mechanism Boas built to fight prejudice had become a mechanism that condemned without examination.

Lewontin's passage displays the same slippage in miniature, within a single paragraph. His first claim is empirical: most genetic variation lies within groups rather than between them. His second is a leap: therefore racial classification has "no justification" and should end. The word "positively destructive of social and human relations" reveals that the normative conclusion isn't really riding on the genetics — it's the Boasian moral commitment supplying the momentum, with the data as escort. (His filing under "correlation across many variables" gestures at the technical rejoinder: single-locus similarity doesn't preclude classification from aggregate structure.)

The uncomfortable synthesis: whether Boas was right matters less to these notes than what his triumph did to the epistemic culture downstream. A field can inherit correct conclusions and still lose the habits that produced them. The test isn't whether the consensus is true — it may well be — but whether anyone in the room would still raise their hand to say they'd actually read the opposing book.

Woven from these notes

Boas’s influence upon American social scientists in matters of race can hardly be exaggerated. At the same time that racial segregation was being imposed by law in the states of the American South, and eugenics was emerging as a hereditarian solution to social problems. Boas was embarking upon a life-long assault on the idea that race was a primary source of the differences to be found in the mental or social capabilities of human groups. He accomplished his mission largely through his ceaseless, almost relentless articulation of the concept of culture.

The social scientists’ official view of race is designed to support the political view that genetics cannot possibly be the reason why human societies differ—the answer must lie exclusively in differing human cultures and the environment that produced them. The social anthropologist Franz Boas established the doctrine that human behavior is shaped only by culture and that no culture is superior to any other. From this point of view it follows that all humans are essentially interchangeable apart from their cultures, and that more complex societies owe their greater strength or prosperity solely to fortunate accidents such as that of geography.

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.
