The Diagnosis Reveals the Diagnostician

2026-07-31 · AI-generated insight

Thayer's Chinese strategists and Stephen Jay Gould are engaged in the same activity: diagnosing someone else's pathology. Beijing looks at American multiculturalism and sees sickness and decline. Gould looked at Morton's skull measurements and saw a racist fudging his data. In both cases, the diagnosis turns out to be at least as revealing about the diagnostician as about the patient.

The Morton affair, as Warne recounts it, ended in a hall of mirrors: anthropologists re-examining the data concluded that it was Gould, not Morton, who bent the numbers toward his prior beliefs. The man who built his reputation exposing motivated measurement was apparently doing motivated measurement. And Thayer's whole framing points the same lens at China — the perception of multicultural America as diseased is not neutral strategic analysis but an artifact of Chinese racial assumptions about what a strong society must look like. The judgment is data about the judge.

But the Morton literature also carries a warning against wielding this move too confidently. Kaplan's position — that Morton's interpretations were flawed but Gould was wrong to think he could discern Morton's motivations — is the crucial one. Attributing bias is itself an act of measurement, and an unusually error-prone one, because the evidence (someone's inner motives) is unobservable and the attribution flatters the attributor. Gould's failure wasn't noticing that racism can distort science; it was believing he could read intent off of data tables.

Applied to Thayer: the strategically useful question is not whether Chinese perceptions of American decline are bigoted — they may well be — but whether they are accurate, and those are independent questions. A biased observer can still see something true; an anti-racist one can still get the numbers wrong. The Morton saga suggests a discipline: separate the empirical claim (does multiculturalism weaken cohesion? do skull sizes differ?) from the moral audit of whoever raised it. Conflating the two is precisely how Gould went wrong — and how a rival's perception could be dismissed right up until it turned out to matter.

Woven from these notes

From the Chinese perspective, the United States used to be a strong society that the Chinese respected when it was unicultural, defined by the centrality of Anglo-­Protestant culture at the core of American national identity aligned with the political ideology of liberalism, the rule of law, and free market capitalism. The Chinese see multiculturalism as a sickness that has overtaken the United States, and a component of U.S. decline.

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.
