A Consensus That Was Selected, Not Discovered

Read together, these notes trace a single arc: the birth of an orthodoxy, its enforcement, and its expiration.
Duedahl supplies the origin story that Wade and Reich merely gesture at. When Wade blames "the social scientists' official view of race," and when Reich describes an "orthodoxy" that treats population genetics as a slippery slope, they are describing something that did not emerge from evidence accumulating in the ordinary way. Duedahl shows it was manufactured: UNESCO issued four statements on race between 1950 and 1967, formulated by "carefully-chosen" scientists, with a deliberate institutional "preference for social scientists rather than physical anthropologists." The consensus was curated to serve cultural internationalism and postwar peace-making — a political end that even Reich, as a geneticist, treats with "deep sympathy."
Here is the uncomfortable synthesis. Once you build a scientific consensus to serve a moral goal, you forfeit the instruments that would tell you when the science is wrong. That is exactly Warne's Gould case. Gould accused Morton of unconsciously fudging skull data to fit his racism — the perfect parable of bias corrupting measurement. Then re-analysis suggested it was Gould who massaged the numbers to fit his anti-racist convictions. The debunker had become the exhibit.
So the same mechanism — Politics Shaping Science, Bias in Scientific Measurement — operates on both sides of the moral ledger. UNESCO chose the social sciences because it knew which answer it wanted; Gould saw manipulation in Morton because he needed to. The lesson is not that the orthodoxy was evil (its architects were often right about the horrors they feared) but that a science optimized for a conclusion loses the ability to detect its own error. Reich's warning — that it is "simply no longer possible to ignore" what genetics now shows — is what that failure eventually costs.
