Tierney and Zywicki
As Tierney points out, institutions of higher education"keep meticulous tabs on the race and gender and ethnic background of their students and faculty, but the lack of political diversity is taken as a matter of course. As long as the professors look different, why worry if they think the same?"
Volokh Conspiracy contributor and Dartmouth trustee Todd Zywicki expands on this theme in an important article published in the most recent issue of American Spectator. I've been unable to find the article on-line, but it builds off arguments Zywicki initially made in this lengthy Volokh post.
Zywicki offers the most persuasive case I have seen that"self-selection is a deeply flawed explanation for the prevailing ideological imbalance on college campuses." He does so by taking apart the most serious critique of the Stanley Rothman study of ideological one-sidedness in the academy, especially at more elite institutions.
The critique's authors cite three elements to sustain their thesis of self-selection: the rural/urban divide (they claim that" conservative" scholars are less likely to want to teach at elite institutions, since such schools are generally in urban areas); regional selection (the Midwest and the South, with fewer elite schools, tend to be more conservative); and the fantastic assertion that"many conservatives may deliberately choose not to seek employment at top-tier research universities because they object, on philosophical grounds, to one of the fundamental tenets undergirding such institutions: the scientific method."
As Zywicki notes, his own institution, Dartmouth, is as rural a college as one could find--yet the party and ideological ratio among its faculty is comparable to that at elite schools located in urban areas. If the regional explanation were compelling, he wonders, how could one account for the findings in the survey that started the recent high-profile controversy, that of the Duke Conservative Union, which showed that Duke's humanities departments had a partisan breakdown of 142 registered Dems to 8 registered Repubs, with the ratio in History 32-0. As for the third element of the critique--which Zywicki correctly notes is so weak that it demonstrates the"straw-gasping" of Rothman's critics--if it were true, shouldn't the ideological disparity between leftists and conservatives be highest in the fields for which the"scientific method" is fundamental, the natural sciences? Yet the reverse is true:"the ideological divide is much narrower in the fields in which the scientific method is used . . . and widest where it is most absent."
Zywicki concludes by noting that the academy would be well served devoting a portion of the money currently spent on"diversity" initiatives and instead" conduct a study of the causes of the ideological disparity in the academy, rather than simply speculate and pontificate. At the very least, such a study would eliminate some of the more preposterous hypotheses--such as self-selection--for the under-representation of conservatives in academia."
I'm not holding my breath, however, that the issue will be high on the agenda of any major group representing the higher education establishment.
