Moral Equality Held Hostage to Empirical Sameness

2026-09-13 · AI-generated insight

Gould makes a startling concession buried in a parenthetical: equality of the races "is not an ethical principle (though equal treatment may be)." It "just worked out that way" — history could have gone otherwise, and the moral dilemmas would have been enormous. This is honest, but it takes a hostage. If your commitment to equal treatment rests on an empirical claim of sameness, then every study of group differences becomes a threat to the moral order itself, not merely a scientific question.

Lewontin's argument shows the same structure even more explicitly: racial classification has "virtually no genetic or taxonomic significance," therefore "no justification can be offered for its continuance." The moral conclusion is derived from the empirical premise. But this means the moral conclusion inherits the fragility of the premise — and Warne's five converging lines of evidence are precisely the kind of finding that puts pressure on it. Warne doesn't claim the case is closed; he claims the environmentalist-only position is empirically contested. Under the Gould–Lewontin framing, that contestation isn't just a scientific dispute — it's an assault on the foundation of equal treatment.

The Coon episode then becomes not an aberration but a predictable consequence of this framing. If the ethical stakes of an empirical question are existential, examining the evidence before condemning it starts to feel like a luxury — or a danger. The anthropologists who denounced a book they hadn't read weren't failing at science so much as succeeding at moral defense, given premises that made the two indistinguishable. Condemnation without examination is what hostage-taking looks like when the ransom comes due.

The irony is that Gould's parenthetical contains the escape route he doesn't take: if equal treatment is an ethical principle rather than an empirical finding, it needs no protection from data. A commitment to treating individuals justly that survives any possible answer to Warne's question is more robust than one that requires his answer to be zero. The notes filed under "Science Against Prejudice" pull in opposite directions here — Lewontin uses science to defeat prejudice by proving sameness; the sturdier move is to make prejudice wrong regardless of what science finds, so that inquiry never has to be forbidden in the first place.

Woven from these notes

Equality [of the races] is not given a priori. It is neither an ethical principle (though equal treatment may be) nor a statement about norms of social action. It just worked out that way. A hundred different and plausible scenarios for human history would have yielded other results (and moral dilemmas of enormous magnitude). They didn't happen.

The past 30 years of research in intelligence has produced a wealth of knowledge about the causes and consequences of differences in intelligence between individuals, and today mainstream opinion is that individual differences in intelligence are caused by both genetic and environmental influences. Much more contentious is the discussion over the cause of mean intelligence differences between racial or ethnic groups. In contrast to the general consensus that interindividual differences are both genetic and environmental in origin, some claim that mean intelligence differences between racial groups are completely environmental in origin, whereas others postulate a mix of genetic and environmental causes. In this article I discuss 5 lines of research that provide evidence that mean differences in intelligence between racial and ethnic groups are partially genetic. These lines of evidence are findings in support of Spearman’s hypothesis, consistent results from tests of measurement invariance across American racial groups, the mathematical relationship that exists for between-group and within-group sources of heritability, genomic data derived from genome-wide association studies of intelligence and polygenic scores applied to diverse samples, and admixture studies. I also discuss future potential lines of evidence regarding the causes of average group differences across racial groups. However, the data are not fully conclusive, and the exact degree to which genes influence intergroup mean differences in intelligence is not known. This discussion applies only to native English speakers born in the United States and not necessarily to any other human populations.

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.
