Lewontin Builds the House Gould Told Him Not To

Read together, Gould and Lewontin are on the same political side but hold incompatible strategies — and Gould's is the one that survives contact with Winegard and Carl.

Lewontin makes a two-step move. Step one is empirical: variation within groups swamps variation between them, so races are "remarkably similar." Step two is normative: therefore "no justification can be offered for" racial classification's "continuance." He welds the moral conclusion directly onto the genetic premise. Anti-racism, in his telling, rests on a fact about allele frequencies.

Gould refuses exactly this weld. Equality, he insists, "is neither an ethical principle... nor a statement about norms." It "just worked out that way," and "a hundred different and plausible scenarios" could have produced deep biological gradients instead. The ethical commitment to equal treatment must therefore float free of any particular empirical result — precisely because the empirical result was contingent and could have gone otherwise.

Now bring in Winegard and Carl. Their skull-classification datum — 80% accuracy from two variables, near-perfect from many — is the classic rebuttal to Lewontin: within-group variance can dominate at single loci while correlations across many variables still cluster people by ancestry. (Note that Lewontin files under "randomly chosen genetic differences"; the counter-note files under "Correlation Across Many Variables." That is the whole argument in two filing tags.)

Here is the pollination. If, like Lewontin, you have staked human equality on the claim that populations are statistically indistinguishable, then every advance in multivariate classification becomes a threat to your ethics. You have handed the moral high ground to whoever wins a technical dispute about covariance structure. Gould saw the trap: an anti-racism mortgaged to a specific empirical finding is an anti-racism awaiting foreclosure.

And the Coon episode shows what foreclosure looks like — a discipline voting to condemn a book almost no one had read, defending a conclusion it could no longer defend on the merits. When the ethics and the empirics are fused, and the empirics wobble, the only tools left are the raised-hand vote and the statement passed regardless. Gould's decoupling isn't a concession to race science; it's the thing that makes anti-racism unfalsifiable-proof.

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 primary reason that natural philosophers began to classify humans into different races is that human populations look different from one another. Their skin colors, hair textures, facial structures, and stature all differ, often in predictable ways. Furthermore, these differences reflect their divergent geographical origins. In fact, researchers can classify human variation by continent quite accurately using only data from the human skull. (They are able to correctly classify human skulls into black and white Americans with about 80% accuracy, using only two variables.) Therefore, despite the common charge that racial classification is ipso facto racist, and that most Enlightenment typologies of human variety were motivated by prejudices and a desire to rationalize imperial domination, ordinary people and Enlightenment philosophers also took to classifying human differences for the mundane reason that such differences actually exist.

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.
