Changing the Answer by Changing Which Science Gets Asked

Degler and Duedahl describe two phases of the same campaign, roughly fifty years apart — and reading them together reveals the campaign's core tactic. Boas didn't primarily refute racial hierarchy with better measurements of skulls (though he did some of that); he changed the discipline that got to answer the question, relentlessly articulating "culture" until social explanation displaced biological explanation as the default. Duedahl shows UNESCO running the identical play at institutional scale: its statements on race drew fire precisely because the organization preferred social scientists over physical anthropologists, making the real dispute one of jurisdiction — "whether the natural or social sciences should take precedence in determining the origins of human difference." The scientific fight over race was, at both stages, substantially a fight over which science owned the topic.
The pairing also complicates Degler's great-man framing. Boas's influence "can hardly be exaggerated" within American social science — but Duedahl's account shows what it took to move the idea beyond that community: four official statements, a publication "bombardment" of national school systems, expert witnesses in the segregation cases, and still nearly two decades before the effort was genuinely global rather than a Western scholars' conversation. Ideas don't diffuse on merit; they require infrastructure, and infrastructure has its own frictions (translation budgets, member-state politics, the failure to even locate non-Western scholars until 1967).
There's an irony buried here too. Boas fought a lonely insurgency against a scientific establishment; by 1950 his intellectual descendants were the establishment being installed by an international body that carefully chose sympathetic experts — Duedahl notes only once was an overt critic included. The anti-racist position was almost certainly correct, but the mechanism of its victory (curated panels, institutional authority, strategic disciplinary preference) mirrors how orthodoxies of any kind get built. Which suggests a general pattern worth watching for: when a scientific consensus shifts, ask not only what new evidence emerged, but which discipline gained custody of the question, and which institution did the choosing.
