How a Heresy Becomes an Orthodoxy Defended Without Evidence

Read together, these two notes trace a full institutional life cycle: an idea that entered anthropology as an evidence-based challenge to consensus and, within a generation, was being defended by means that required no evidence at all.

Degler's account of Boas presents the culture-over-biology position at its origin — a radical claim, advanced against the prevailing scientific view, and grounded in an empirical argument: observed social differences trace to divergent histories, not divergent biology. Whatever one thinks of the conclusion, the mode was scientific. Boas won converts by making a case.

The Coon episode shows the same position roughly fifty years later, now the establishment view, being defended in precisely the opposite mode. The AAA anthropologists who denounced Putnam's book had, almost to a person, not read it — several hadn't heard of it. The vote wasn't an evaluation of an argument; it was a boundary-maintenance ritual. The content of the heresy was irrelevant; what mattered was that it was heresy.

The irony is sharp: a paradigm born from the refusal to accept received wisdom about race was, by 1961, enforced through the refusal to examine dissent from it. This suggests something general about how ideas travel through institutions. The epistemic virtues that establish a position — openness to evidence, willingness to challenge consensus — are not the same virtues that maintain it. Maintenance runs on social machinery: professional associations, official statements, reputational costs. And that machinery is content-neutral; it defends whatever occupies the orthodox position, by whatever means preserve the boundary.

This also complicates the second note's framing of public trust. Laypeople trust scientists because they assume the Boasian mode — evidence weighed, arguments examined — operates continuously. But the AAA vote reveals that scientific institutions can toggle into the enforcement mode while still speaking with the voice of scientific authority. The public can't tell from outside which mode produced a given official statement. The lesson isn't that either side of the race debate was right; it's that an official scientific consensus carries two very different kinds of pedigree — earned and enforced — and they look identical on the letterhead.

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.

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
