When Science Is Enlisted for a Mission, the Verdict Can Precede the Evidence

All four of these notes are filed under "Science Against Prejudice," and that shared tag conceals a fight: the phrase means opposite things depending on who holds it. For Degler's Boas and for Lewontin, science is the weapon against prejudice — the empirical demonstration that culture, not race, explains human difference. For Winegard and Carl, and in the Coon anecdote, the prejudice to be fought is the reflexive assumption that studying racial difference must itself be racist. Each camp sees itself as defending inquiry against ideology.

The notes also reveal the mechanism by which a scientific mission can hollow out scientific practice. Degler describes Boas's method admiringly as "ceaseless, almost relentless articulation" — which is the vocabulary of advocacy, not of experiment. Lewontin's quote performs the slide openly: it moves in a single breath from an empirical claim (most genetic variation is within groups) to a normative verdict ("no justification can be offered for its continuance"). When the moral conclusion is pre-certified as good, the evidentiary work starts to feel optional. That is exactly what the Coon story dramatizes: an anthropological association formally denouncing a book that, by show of hands, one member had read. Condemnation without examination isn't a betrayal of the mission — it's the mission running without the science.

There's a quieter empirical echo, too. Lewontin's argument rests on "randomly chosen genetic differences" considered one at a time; the Winegard and Carl note supplies the standard rejoinder without naming it — that traits correlate, so two skull variables alone classify populations with 80% accuracy. One note answers the other across the page.

The synthesis isn't that either side is right about race. It's that "science against prejudice" is an unstable compound: the moment the against prejudice part becomes the load-bearing commitment, the science part risks becoming ceremonial — a raised hand in a meeting, endorsing a conclusion no one checked. Boas's legacy and Coon's resignation may be two chapters of the same cautionary tale.

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 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.
