Ideas Don't Win Arguments; They Win Infrastructure

Read together, these notes trace the full lifecycle of a scientific idea's victory — and quietly complicate the story of how that victory was won.

Degler shows the idea at its origin: Boas's "ceaseless, almost relentless articulation" of culture over biology. The word choice matters. Boas didn't win by producing a single decisive experiment; he won by repetition, by campaign. Duedahl then shows the next stage: UNESCO taking Boas's position and scaling it — four statements between 1950 and 1967, publications "infiltrating national educational systems," experts testifying before the U.S. Supreme Court. And Diamond represents the endpoint: the position so thoroughly absorbed that a bestseller can state it in a single sentence, as premise rather than argument.

But Duedahl's account contains an uncomfortable detail that the triumphal version omits: UNESCO's scientists were "carefully-chosen," mostly Western, weighted toward social scientists over physical anthropologists, with a genuine critic included only once. The organization was manufacturing consensus as much as reporting it. This doesn't make the conclusion wrong — but it means the anti-racist scientific consensus won partly the same way bad ideas win: through curation, institutional amplification, and strategic exclusion of dissenters. Science against prejudice was also politics shaping science.

There's a second, subtler tension between Boas and Diamond. Both reject biological explanations, but they substitute different causes. Boas says group differences are "the product of different histories" — an open-ended, contingent, cultural claim. Diamond says they're products of environments — a claim that risks reintroducing determinism through the back door, with geography playing the role biology once played. Peoples still don't author their own fates in Diamond's account; the determining force has just moved from the genome to the landscape. Boas's framework leaves more room for contingency and human agency than the popularization that descended from it.

The synthesis: an idea's path from heresy to common sense runs through individuals willing to repeat themselves for decades, institutions willing to stack the deck, and popularizers willing to simplify. Each stage is necessary; each also distorts. The question these notes leave open is whether any idea — true or false — could travel this pipeline without the same compromises.

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.

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.

History followed different courses for different peoples because of differences among peoples’ environments, not because of biological differences among peoples themselves.

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.
