Moral Appeal Is a Tailwind, Not a Truth Test

Degler describes one of social science's proudest episodes: Franz Boas's culture concept displacing race as the explanation for human difference, spreading with "remarkable" speed across disciplines in the early twentieth century. Inzlicht's confession quietly complicates the celebration. He admits that feeling "on the right side of history" gave him moral cover for p-hacking — his conclusions were "what the good guys already believed," so they faced less scrutiny, including his own.

Put these together and the speed of Boas's diffusion looks double-edged. Ideas that flatter our moral commitments travel faster than ideas that don't, regardless of whether they're true. Boas happened to be right — or at least far more right than the racial science he displaced. But the mechanism that carried his idea across disciplines wasn't a truth-detector; it was the same mechanism that carried Inzlicht's shaky findings into journals and TED-adjacent acclaim. Social scientists in 1910 "testified to the influence" of Boas partly because his framework let them stop defending an increasingly repugnant biological determinism. The moral relief was real, and it did epistemic work it wasn't qualified to do.

This suggests an uncomfortable audit question: which of our current consensus positions are held with Boasian confidence but Inzlichtian evidence? The replication crisis hit social psychology hardest precisely in areas where findings confirmed progressive intuitions — stereotype threat, implicit bias, ego depletion as a lever for compassion. None of this vindicates the racial theorists Boas defeated; it means the defeat itself can't serve as the proof. Boas's concept ultimately earned its keep through decades of ethnographic and genetic evidence, not through its moral appeal in 1905.

The practical upshot: moral welcomeness should raise, not lower, the evidentiary bar. When a finding makes you feel like one of the good guys, that feeling is exactly the moment Inzlicht warns about — and the fact that history sometimes rewards the morally attractive idea, as it did Boas, is what makes the trap so comfortable to fall into.

Woven from these notes

Until the 1890s Boas used the term as his fellow anthropologists did: as another word for civilization or “high culture.” Franz Boas’s exposition of the concept of culture as an alternative to race in accounting for differences among human groups was a genuine seminal contribution. The idea not only conquered his own field of anthropolgy but spread as well to other social science disciplines. The diffusion was remarkably rapid. Again and again in the early years of the new century American social scientists outside of anthropology testified to the influence of his writings on their conception of human nature and the place of biology or race within it.

My work was uplifting people, or so I told myself. Looking back, I suspect that feeling like I was on the right side of history was a kind of moral cover. Maybe I felt less wrong about the p-hacking because I was promoting social justice. The conclusions I drew were what the good guys already believed, after all.
