Gould's Thesis Refutes Gould, and Vindicates Him

2026-08-08 · AI-generated insight

The strange thing about the Morton skull affair, as Warne recounts it, is that Stephen Jay Gould's central thesis came out looking stronger even as Gould himself came out looking worse. Gould's argument in The Mismeasure of Man was that bias operates unconsciously — that Morton didn't need to be a deliberate fraud, because a scientist's convictions can quietly steer his measurements without his ever noticing. When anthropologists re-measured the skulls in 2011 and concluded that it was Gould, not Morton, who had bent the data toward his beliefs, they didn't overturn that thesis. They supplied its best confirming instance. The mechanism Gould described was real; he simply failed to imagine it running through himself. Kaplan's middle position captures the irony precisely: Morton's era-bound interpretations were flawed, and Gould was wrong to think he could read motives out of data — a caution that applies with equal force to Gould's readers judging Gould.

The Coon episode shows the same mechanism operating one step earlier in the pipeline — before any data is even consulted. The AAA members who denounced Putnam's book hadn't read it; most hadn't heard of it. Their moral certainty didn't distort their examination of the evidence, as with Gould; it substituted for examination altogether. This is the more efficient failure mode. Gould at least had to labor over Morton's tables to reach his predetermined conclusion. The anthropologists in that room needed only a show of hands.

Together the notes suggest a rule: the confidence that one is fighting prejudice is itself a bias-amplifier, because it converts epistemic corner-cutting into a virtue. The scientist who believes he is merely describing the world watches his methods; the scientist who believes he is defending the innocent feels licensed not to. Coon's resignation and the 2011 re-measurement both point to the same remedy — not purer motives, but audit trails. Morton published his raw measurements, which is the only reason anyone, Gould included, could check him. The AAA's secret meeting left nothing to check at all.

Woven from these notes

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.
— Russell T. Warne The Mismeasurements of Stephen Jay Gould
Carleton Coon was one of the greatest anthropologists of the 20th century and a champion of the study of racial differences. In 1961 he was elected president of the American Anthropological Association. It was during this year that Carleton Putnam's infamous book Race and Reason came out. Putnam's book argued that there were significant differences between the races and that this had important political implications. A few anthropologists became upset when they saw the book gain popularity and wanted the AAA to intervene. But they knew that Coon supported the book and that, as a result, having the AAA take action against it would be difficult. So they organized a secret meeting behind Coon's back in order to issue a statement denouncing Putnam's work. Coon found out about the meeting and went to stop it. Upon entering the meeting Coon asked all the association members who had actually read Putnam's book to raise their hands. Only one rose. He then asked for the hands of everyone that had even heard of the book prior to that meeting. Only a few hands rose. None the less, the statement against the book passed. Coon, disgusted by the actions of his peers, resigned from the AAA (1). This incident stands out in the history of science as a particularly clear example of scientists not living up to what people expect of them. People often take what scientists say for granted. They trust that scientists have looked at the evidence rationally and are giving the public as accurate an account of all the relevant facts as they can. When explaining science to laypeople researchers are expected to only make authoritative statements on topics they are knowledgeable of, to not lie about scientific evidence, and to not omit obviously relevant facts. People trust scientists to do these things and so feel comfortable taking what they tell them for granted. (See
