The Anti-Racist Scientist's Mirror Problem

Degler describes Franz Boas's culture concept spreading through the social sciences with "remarkable" speed — a genuinely seminal idea displacing race as the explanation for human difference. But Warne's account of the Gould-Morton affair raises an uncomfortable question about why ideas like this spread so fast: was it the strength of the evidence, or the moral relief the idea offered?

The Gould saga is almost a parable on this point. Gould accused Morton of unconsciously fudging skull measurements to confirm his racist priors — and then anthropologists re-examining the data argued that it was Gould who had manipulated the analysis to confirm his priors. Whatever the final verdict (and Warne shows the scholarly literature never reached one), the episode demonstrates that motivated reasoning is symmetric. The desire to debunk racism is still a desire, and desires bend data. Gould's central insight — that scientists unconsciously see what they expect to see — turned out to apply most vividly to Gould himself.

This casts Boas's triumph in a more ambivalent light. The culture concept may well be correct, and its victory over racial determinism was surely a moral good. But Degler's observation that social scientists "testified to the influence" of Boas's writings on their view of human nature sounds less like the slow accumulation of evidence and more like conversion. Ideas that let a field feel virtuous face weaker scrutiny than ideas that make it feel complicit — which means the diffusion speed Degler marvels at might itself be a warning sign.

The synthesis: "science against prejudice" is not a stable category. Science can be deployed against prejudice, but the deployment creates its own prejudice — a strong prior about which conclusions are acceptable. The Morton skulls have now been measured by partisans of at least three positions, each finding roughly what they needed to find. The lesson isn't that Morton was right or that Boas was wrong; it's that the moral valence of a scientific claim is orthogonal to its truth, and a field that forgets this will eventually produce its own Goulds — crusaders whose errors go unexamined precisely because their cause is just.

Woven from these notes

Until the 1890s Boas used the term as his fellow anthropologists did: as another word for civilization or “high culture.” Franz Boas’s exposition of the concept of culture as an alternative to race in accounting for differences among human groups was a genuine seminal contribution. The idea not only conquered his own field of anthropolgy but spread as well to other social science disciplines. The diffusion was remarkably rapid. Again and again in the early years of the new century American social scientists outside of anthropology testified to the influence of his writings on their conception of human nature and the place of biology or race within it.

Many scholars have criticized The Mismeasure of Man periodically throughout its 38-year history. For example, James T. Sanders stated that Gould’s attempt to link his argument to anti-racism was a ploy to smear intelligence scholars and Gould’s enemies as evil people. Arthur Jensen argued in 1982 that Gould misrepresented Jensen’s ideas and often demolished strawmen that no intelligence scholar believes, including the boogeyman of “biological determinism.” John Carroll showed that Gould understood neither the purpose nor interpretation of factor analysis (a statistical procedure often used to evaluate data from psychological tests) and that Gould’s attacks on factor analysis do nothing to alter the importance of intelligence tests, nor the mass of evidence—impossible to dispute—that they predict real-life outcomes. Most criticism of The Mismeasure of Man was confined to the recherché world of psychologists who study intelligence. However, a new debate opened up in 2011 when a team of anthropologists argued that Gould’s analysis of the data on cranium measurements from 19th century scientist Samuel George Morton was flawed. Gould cast Morton as a racist who fudged his data to match his beliefs about white racial superiority because of a supposed larger skull capacity. Instead, the anthropologists argued, it was Gould who manipulated the data to support his biases. This ignited a series of follow-up articles in the scholarly literature by authors taking a variety of positions regarding Morton’s data and Gould’s interpretations. Weisberg believed that the re-analysis was flawed and Gould was mostly correct. Kaplan and his colleagues claimed that Morton’s interpretations were flawed, but that Gould was incorrect in believing that he could discern Morton’s actions and motivations. Finally, Mitchell believed that Morton’s data were accurate and that the interpretations were colored by the racism of the era, but the claim that Morton subtly manipulated the data was a fiction created by Gould.
