For all the shock value of its assertion that blacks are intractably, and probably biologically, inferior in intelligence to whites and Asians, The Bell Curve is not quite an original piece of research. It is, in spite of all the controversy that is attending its publication, only a review of the literature—an elaborate interpretation of data culled from the work of other social scientists. For this reason, the credibility of its authors, Charles Murray and Richard J. Herrnstein, rests significantly on the credibility of their sources.

The press and television have for the most part taken The Bell Curve’s extensive bibliography and footnotes at face value. And, to be sure, many of the book’s data are drawn from relatively reputable academic sources, or from neutral ones such as the Census Bureau. Certain of the book’s major factual contentions are not in dispute—such as the claim that blacks consistently have scored lower than whites on IQ tests, or that affirmative action generally promotes minorities who scored lower on aptitude tests than whites. And obviously intelligence is both to some degree definable and to some degree heritable.

The interpretation of those data, however, is very much in dispute. So, too, are the authors’ conclusions that little or nothing can or should be done to raise the ability of the IQ-impaired, since so much of their lower intelligence is due to heredity. Murray and Herrnstein instead write sympathetically about eugenic approaches to public policy (though they do not endorse them outright). It is therefore interesting that Charles Murray recently expressed his own sense of queasiness about the book’s sources to a reporter from The New York Times: “Here was a case of stumbling onto a subject that had all the allure of the forbidden,” he said. “Some of the things we read to do this work, we literally hide when we’re on planes and trains. We’re furtively peering at this stuff.”1

What sort of “stuff” could Murray mean? Surely the most curious of the sources he and Herrnstein consulted is Mankind Quarterly—a journal of anthropology founded in Edinburgh in 1960. Five articles from the journal are actually cited in The Bell Curve’s bibliography (pp. 775, 807, and 828).2 But the influence on the book of scholars linked to Mankind Quarterly is more significant. No fewer than seventeen researchers cited in the bibliography of The Bell Curve have contributed to Mankind Quarterly. Ten are present or former editors, or members of its editorial advisory board. This is interesting because Mankind Quarterly is a notorious journal of “racial history” founded, and funded, by men who believe in the genetic superiority of the white race.3

Mankind Quarterly was established during decolonization and the US civil rights movement. Defenders of the old order were eager to brush a patina of science on their efforts. Thus Mankind Quarterly’s avowed purpose was to counter the “Communist” and “egalitarian” influences that were allegedly causing anthropology to neglect the fact of racial differences. “The crimes of the…
