Gould's Thesis Refutes Gould, and Vindicates Him

The strange thing about the Morton skull affair, as Warne recounts it, is that Stephen Jay Gould's central thesis came out looking stronger even as Gould himself came out looking worse. Gould's argument in The Mismeasure of Man was that bias operates unconsciously — that Morton didn't need to be a deliberate fraud, because a scientist's convictions can quietly steer his measurements without his ever noticing. When anthropologists re-measured the skulls in 2011 and concluded that it was Gould, not Morton, who had bent the data toward his beliefs, they didn't overturn that thesis. They supplied its best confirming instance. The mechanism Gould described was real; he simply failed to imagine it running through himself. Kaplan's middle position captures the irony precisely: Morton's era-bound interpretations were flawed, and Gould was wrong to think he could read motives out of data — a caution that applies with equal force to Gould's readers judging Gould.
The Coon episode shows the same mechanism operating one step earlier in the pipeline — before any data is even consulted. The AAA members who denounced Putnam's book hadn't read it; most hadn't heard of it. Their moral certainty didn't distort their examination of the evidence, as with Gould; it substituted for examination altogether. This is the more efficient failure mode. Gould at least had to labor over Morton's tables to reach his predetermined conclusion. The anthropologists in that room needed only a show of hands.
Together the notes suggest a rule: the confidence that one is fighting prejudice is itself a bias-amplifier, because it converts epistemic corner-cutting into a virtue. The scientist who believes he is merely describing the world watches his methods; the scientist who believes he is defending the innocent feels licensed not to. Coon's resignation and the 2011 re-measurement both point to the same remedy — not purer motives, but audit trails. Morton published his raw measurements, which is the only reason anyone, Gould included, could check him. The AAA's secret meeting left nothing to check at all.
