Good Intentions Are Not a Method: When Anti-Prejudice Becomes Its Own Bias

2026-07-29 · AI-generated insight

Read together, these four notes stage a quiet civil war inside the single file "Science Against Prejudice." Degler gives us the hero: Boas, whose relentless articulation of culture toppled the race concept precisely as segregation and eugenics were ascendant. That is science serving virtue. But the other three notes ask an uncomfortable follow-up: what happens when the virtue starts steering the science?

Warne's account of Gould supplies the cleanest irony. Gould accused Samuel Morton of unconsciously fudging cranial data to flatter his racial beliefs — and the 2011 re-analysis accused Gould of doing exactly that, massaging Morton's numbers to fit an anti-racist conclusion. Bias turns out to be symmetric. The man who wrote the canonical exposé of measurement bias may have been its next exhibit. Motive did not immunize method.

The Coon episode names the mechanism outright: an entire professional body voting to denounce a book almost none of them had read. The cause was righteous; the epistemic act — condemnation without examination — was indistinguishable from the dogmatism it opposed.

And notice Lewontin's move: he establishes an empirical claim (most human variation is within groups) and then glides, in the very next breath, to "no justification can be offered for its continuance." The first sentence is genetics; the second is politics wearing genetics as a badge. Edwards later called this slide a fallacy precisely because low variance on randomly chosen markers doesn't survive correlation across many variables.

The pollinated insight: Boas is celebrated and Gould, the AAA, and (arguably) Lewontin are indicted — yet all were fighting prejudice. The file's real lesson is that the nobility of the enemy you're fighting purifies nothing. A good cause is the most flattering disguise a bad inference can wear.

Woven from these notes

Boas’s influence upon American social scientists in matters of race can hardly be exaggerated. At the same time that racial segregation was being imposed by law in the states of the American South, and eugenics was emerging as a hereditarian solution to social problems. Boas was embarking upon a life-long assault on the idea that race was a primary source of the differences to be found in the mental or social capabilities of human groups. He accomplished his mission largely through his ceaseless, almost relentless articulation of the concept of culture.

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.

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
It is clear that our perception of relatively large differences between human races and subgroups, as compared to the variation within these groups, is indeed a biased perception and that, based on randomly chosen genetic differences, human races and populations are remarkably similar to each other, with the largest part by far of human variation being accounted for by the differences between individuals. Human racial classification is of no social value and is positively destructive of social and human relations. Since such racial classification is now seen to be of virtually no genetic or taxonomic significance either, no justification can be offered for its continuance.
