Two columns ago , I discussed evolutionary psychologist Gordon Gallup’ s theory about the possible adaptive function of homophobia, or, more broadly defined, negative attitudes toward gay people. Central to his position--which, he assures me, has not since wavered--is that homophobic responses "are proportional to the extent to which the homosexual [is] in a position that might provide extended contact with children and/or would allow the person to influence a child’s emerging sexuality." I also described a set of studies meant to test some hypotheses related to this theory, and which, according to Gallup, offered provisional evidentiary support.
I expressed some unease with the implications (and insinuations) of Gallup’s line of argument. But I was also rather unabashed in my conviction that his theory, though impolitic, was not only plausible, but also insightful and worth revisiting, particularly now, when homophobia may be too hastily, and simplistically, characterized as "socially learned." To explicate, using the neutral language of evolution, the idea that homophobia may be adaptive, and furthermore that it is adaptive because children exposed to homosexuals may themselves develop same-sex attractions , is a delicate affair, to say the least. It is tempting to see Gallup’s position, as many indeed have, as a homophobia apologetic disguised as science, one that was specific to a particular time and place. A 2006 piece by psychologist Stephen Clark , for example, accused Gallup of "suggest[ing] that negative attitudes and discrimination directed toward homosexuals are justified on evolutionary grounds." Jeremy Yoder , a PhD student studying evolutionary biology, concludes similarly that Gallup’s unwarranted argument "gives natural selection approval to prevailing ugly stereotypes."
