This is very intriguing, but true. I don't know what to say, so I'll just post some excerpts from it.
Maybe it's time to admit the obvious. We don't really care about diversity all that much in America, even though we talk about it a great deal. Maybe somewhere in this country there is a truly diverse neighborhood in which a black Pentecostal minister lives next to a white anti-globalization activist, who lives next to an Asian short-order cook, who lives next to a professional golfer, who lives next to a postmodern-literature professor and a cardiovascular surgeon. But I have never been to or heard of that neighborhood. Instead, what I have seen all around the country is people making strenuous efforts to group themselves with people who are basically like themselves.
Even though race and ethnicity run deep in American society, we should in theory be able to find areas that are at least culturally diverse. But here, too, people show few signs of being truly interested in building diverse communities. If you run a retail company and you're thinking of opening new stores, you can choose among dozens of consulting firms that are quite effective at locating your potential customers. They can do this because people with similar tastes and preferences tend to congregate by ZIP code.
The segmentation of society means that often we don't even have arguments across the political divide. Within their little validating communities, liberals and conservatives circulate half-truths about the supposed awfulness of the other side. These distortions are believed because it feels good to believe them.
It's striking that the institutions that talk the most about diversity often practice it the least. For example, no group of people sings the diversity anthem more frequently and fervently than administrators at just such elite universities. But elite universities are amazingly undiverse in their values, politics, and mores. Professors in particular are drawn from a rather narrow segment of the population. If faculties reflected the general population, 32 percent of professors would be registered Democrats and 31 percent would be registered Republicans. Forty percent would be evangelical Christians. But a recent study of several universities by the conservative Center for the Study of Popular Culture and the American Enterprise Institute found that roughly 90 percent of those professors in the arts and sciences who had registered with a political party had registered Democratic. Fifty-seven professors at Brown were found on the voter-registration rolls. Of those, fifty-four were Democrats. Of the forty-two professors in the English, history, sociology, and political-science departments, all were Democrats. The results at Harvard, Penn State, Maryland, and the University of California at Santa Barbara were similar to the results at Brown.
What we are looking at here is human nature. People want to be around others who are roughly like themselves. That's called community. It probably would be psychologically difficult for most Brown professors to share an office with someone who was pro-life, a member of the National Rifle Association, or an evangelical Christian. It's likely that hiring committees would subtly-even unconsciously-screen out any such people they encountered. Republicans and evangelical Christians have sensed that they are not welcome at places like Brown, so they don't even consider working there. In fact, any registered Republican who contemplates a career in academia these days is both a hero and a fool. So, in a semi-self-selective pattern, brainy people with generally liberal social mores flow to academia, and brainy people with generally conservative mores flow elsewhere.
Sad but true. Diversity and equality in some ways go against human nature.
