When the Right Side of History Underwrites the Science

Lewontin's famous finding — that most human genetic variation lies within populations rather than between them — is presented here as a single seamless movement: a statistical result flows directly into a moral verdict ("positively destructive of social and human relations") and back again, each half reinforcing the other. Read on its own, the passage feels airtight. Read next to Inzlicht's confession, it becomes a case study in exactly the dynamic Inzlicht describes.

Inzlicht's insight is not that ideologues fake data. It's subtler: feeling like you're on the right side of history functions as moral cover that quietly lowers your evidentiary standards. When "the conclusions I drew were what the good guys already believed," the internal auditor relaxes. The p-hacking didn't feel like dishonesty because it felt like justice.

This is the lens through which Lewontin's rhetoric deserves scrutiny — not necessarily his statistics, but the architecture of the argument. Notice the move from "of virtually no genetic or taxonomic significance" to "no justification can be offered." The empirical claim and the ethical claim are welded together so that questioning one feels like endorsing racism. That welding is precisely what makes the science harder to audit. Critics later argued (the so-called "Lewontin's fallacy") that single-locus comparisons understate the information in correlated loci — a technical objection that, under Inzlicht's dynamic, would have faced unusual friction, because raising it meant stepping off the right side of history.

The uncomfortable synthesis: the more morally urgent a scientific conclusion, the more adversarial scrutiny it needs, and the less it tends to receive. Inzlicht's replication-crisis confession suggests the corrective isn't cynicism about anti-racist science — Lewontin's core finding has held up reasonably well — but a discipline of separation. State the empirical claim so it can fail. State the moral claim so it doesn't depend on the empirical one surviving. Racism would not become justified if between-group variation were larger than Lewontin found; a moral position that secretly rests on a contingent statistic is hostage to the next dataset.

Lewontin wanted science to disarm prejudice. Inzlicht warns that when scientists want something that badly, the wanting itself becomes a methodological variable — one that no significance test will catch.
