A while ago, in the comments following this, I wrote:

It occurs to me that the implications of social construction can appeal to rather unsavoury motives. If a person’s tastes and disposition are primarily socially constructed, that person can also, presumably, be remade to suit society and its representatives. Such high-minded Agents of Society might even become “engineers of the human soul,” to borrow Stalin’s phrase. The idea of innate disposition and talent is in some circles quite contentious, not least with regard to intelligence and its unequal distribution. This seems to cause unease in ways that, say, the unequal distribution of musical or athletic talent does not. It also undermines many conceptions of egalitarianism, which is probably why it causes such a fuss.

And it does cause a fuss. It’s possible, for instance, to find people who are (or will be) employed precisely because of their well above average intelligence performing extraordinary contortions to deny the existence of the intelligence they possess. Some, like Joseph Kugelmass, an English graduate student at the University of California, say things like this:

The abstract personal definition of “intelligence,” reified in our minds thanks to IQ tests and their derivatives, is a source of social ills and should be abandoned. It impedes and confuses pedagogy, underwrites racism and sexism, inhibits culture, and trivializes political debate… To claim that intelligence exists as a phenomenon, but not as an inherent personal quality, is the same as arguing that race or gender exist as social phenomena but not as simple, natural facts. […] Intelligence, like all essentialism, is a technology of power. It reinforces privilege and hierarchizes speech. It cuts art and language off from its inspirations, aping capital by circulating language through a series of useless oppositions… and non-signifying refinements of craft.

Setting aside the tendentious postmodern framing, dutifully regurgitated, note how the objection to intelligence as a personal attribute is asserted rather than argued and is essentially political in origin.

With the above in mind, here’s a short TED lecture from 2003, in which Steven Pinker addresses the political appeal of the “blank slate” theory, its prevalence, and its shortcomings. Topics touched on include ideological taboos, experience versus theory, and the self-inflicted disrepute of literary criticism.

Pinker’s book, The Blank Slate: The Modern Denial of Human Nature, is well worth reading.

Time for another episode of the excellent documentary series The Planets, this time on the Sun. Titled Star, the episode captures the magnitude of several “Eureka!” moments, as when Angelo Secchi, the Vatican’s chief astronomer, realised the blinding disc in the daytime sky is another one of those points that twinkle at night. As with previous episodes, there’s plenty of rare footage and some interesting characters, not least Kristian Birkeland, who created laboratory auroras while wearing a fez to protect his brain from radiation.

The issue of classroom political advocacy crops up here quite often and Evan Maloney’s documentary, Indoctrinate U, illustrates just how far advocacy can go, and how corrosive to probity it can be. A key scene in Maloney’s film concerns psychology professor Laura Freberg, who faced a campaign of harassment by left-leaning colleagues and was told, “We never would have hired you if we knew you were a Republican.” Freberg’s students later admitted they’d known she was a “closet Republican” precisely because she didn’t use the classroom to air her political views.

A recent post on classroom advocacy at Crooked Timber, a site popular among left-leaning academics, has prompted some interesting comments: 

There’s really just the media and you, the universities, between civilization and chaos, and you are natural enemies because reality is liberal and media is corporatist. […] If we lose to McCain, at some point you can say goodbye to your pretty little university system. […] I’d say meet in darkened caves in the middle of the night if that’s what it takes to get out the truth.

Some take a more nuanced view:

I expect my students to respect my statements in class as authoritative (although not necessarily correct), and so I have a responsibility to limit what I say in class to what is warranted by my expertise. Since candidate preference is not a matter of expertise, it would be remiss of me to indicate a preference for a specific candidate when teaching. However, this doesn’t apply to my non-teaching related interactions with students at the university where I teach.

It’s not all bad, of course.

Indoctrination only makes sense if you believe reasoning won’t actually win over the students.

But even if we set aside the not insignificant issue of whether professors of, say, literary criticism have any business trying to “win over” their students and mould their political outlook, reasonably or otherwise, there is another problem. Is the student-professor relationship sufficiently equal and reciprocal to ensure evidence and reason prevail? Is there no pressure on students to defer, to please? Can we simply assume that improper leverage will never be brought to bear – for instance, in terms of grading or more subtle signs of displeasure? And isn’t there an unavoidable air of… predation?
