How an Argument Becomes an Orthodoxy: The Life Cycle of the Antiracist Consensus

2026-07-20 · AI-generated insight

Read together, these three notes trace the full life cycle of a scientific idea — from insurgency, to institution, to orthodoxy that must now defend itself against new evidence.

Degler shows the insurgent phase: Boas waging a "life-long assault" on racial explanations of human difference, armed with the concept of culture, at precisely the moment segregation and eugenics were ascendant. Duedahl shows the institutional phase: UNESCO taking what was, as he notes, essentially "a few scholars' idea of race" and deliberately manufacturing global consensus around it — carefully choosing sympathetic scientists, favoring social scientists over physical anthropologists, bombarding national education systems with publications, and supplying expert witnesses for the Supreme Court cases that dismantled segregation. This is worth pausing on: the mid-century consensus that race is not biologically meaningful was not simply discovered; it was strategically constructed and promoted by an institution that initially excluded its critics from the drafting table.

Reich then documents the orthodox phase — and its crisis. The position Boas fought for and UNESCO globalized has hardened into a doctrine that treats even well-intentioned research into population genetics as a slippery slope back to eugenics. The irony is sharp: a movement that began by insisting science must overturn socially convenient beliefs now polices science to protect a socially necessary belief.

The deeper question these notes pose together is whether the Boas-UNESCO strategy contained a hidden liability. By fusing the empirical claim (racial differences don't explain group outcomes) with the moral claim (all humans deserve equal treatment), the campaign made the moral commitment hostage to the empirical one. Reich is trying to unfuse them — to argue that human equality must rest on grounds sturdier than a factual claim genetics might complicate. Duedahl's history suggests why that's so hard: the fusion wasn't an accident but the deliberate design of the mid-century campaign, and it worked precisely because it presented a moral position as settled science. Undoing that architecture without collapsing the moral achievement it supports is the dilemma Reich inherits.

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 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.”

In 1997, Akira Iriye characterized UNESCO as a hub for cultural internationalism in the wake of World War II, and recent research has confirmed the impression of the organization as an excellent prism reflecting ways of thinking that became popular on a global scale and that it has sometimes even served as the initiating and powerful promotor of concepts that became popular and widely used, such as ‘world heritage’ and ‘global citizenship’. In this article, I have sought to demonstrate another example of the proactive role of UNESCO. The articles has focused on the organization’sefforts to launch a program supposed to combat racial inequality, which is not mentioned by Iriye, but which according to other scholars, placed the organization in the middle of a dispute in international scientific circles over the correct definition of the concept of race. Thus, in the article I have combined Iriye’s focus on the importance of cultural internationalism for global peace-making and UNESCO’s important role with the studies of the organization’s work within the field of race as well as my archival findings in order to draw a conclusion as to whether its showdown with the race concept had a global impact. What we see is that, from 1950 to 1967, UNESCO managed to issue four statements of race formulated by some of the world’s leading yet simultaneously carefully-chosen scientists, most Western and all stressing human equality. The organization’s preference for social scientists rather than physical anthropologists at the same time made the organization a centre of a dispute organized around the question of whether the natural or social sciences should take precedence in determining the origins of human difference, of social division, and the attribution of value. Outside of UNESCO headquarters, the statements for the same reasons caused severe criticism in a time still characterized by European colonialism, American segregation, and South African apartheid policies. Only on one occasion, in 1964, was a researcher chosen despite being overtly critical towards the organization’s work and only in 1967 could the panel of scientists be characterized as truly global in its scope and composition. UNESCO also issued a series of publications that were able to infiltrate national educational systems and which represented a steady bombardment of publications that at least physical anthropologists had to deal with. Critique of their content nonetheless only added to public awareness of the organization’s work. As the cases on segregation reached the U.S. Supreme Court, the outcome of UNESCO’s race program would also play a role. This article shows that experts affiliated with the organization were on several occasions brought in as expert witnesses and that the statements on race highlighted as the newest available research, paving the 16 P. DUEDAHL way towards the eradication of state-approved segregation in the U.S., whereas South Africa chose to withdraw from UNESCO. In sum, the statements and the authority with which the experts spoke had an impact and came to play a major part in imposing the new post-war view of man in several countries. However, it is only after 1960 that UNESCO’s cultural internationalism within the field of race can be said to focus on racism as a problem that had to be solved on a global scale. The main reasons for this was that discussions within academic circles ahead of UNESCO’s race efforts had mainly been going on among Western scholars, that UNESCO failed to locate non-Western scholars, and that dealing with racism was perceived as most urgent in the U.S. and South Africa. Also the expensiveness of translating UNESCO’s findings into all languages, the difficulties of promoting the content in a way that would have an impact on a larger group of people, and the lack of control over the many national environments that received and were supposed to distribute news from UNESCO made a difference. Only after a range of anti-Semitic incidents, the demands of a number of new Asian and African member states, and pressure from the UN, did the initiative gradually change. Altogether, it proved to be more difficult and to take a considerably longer time than initially imagined by UNESCO to turn a few scholar’s idea of race into one with a truly global appeal and impact.
