Well, you certainly hear that sort of talk on CC, and you also hear it among hand-wringing humanities faculty. I’m just not so sure it’s true that undergraduate students are flocking to STEM fields; I’d like to see some hard evidence. At least at the top schools, that just doesn’t seem to be the case.
At Yale, for example, only 25% of the bachelor’s degrees awarded in 2013-2014 were in STEM majors. Of that, 10% were in biological sciences alone, and as ucbalumnus correctly points out, bio majors don’t have particularly lucrative job prospects with an undergraduate bio degree (though no doubt a high percentage of Yale bio majors go on to medical school). As many Yale grads majored in English (7%) as math and physical sciences combined (3% and 4%, respectively); another 7% majored in history.
At Harvard the STEM figure was higher, 37% (figures for 2012-2013). Still, that’s barely over 1/3 of the undergraduate degrees awarded. These are very bright and capable students who can study and do well at anything they want; yet by a landslide they do not choose STEM fields.
At Princeton about 40% chose STEM majors. At Dartmouth 30%. Even at STEM-heavy Stanford, the beating heart of Silicon Valley, more bachelor’s degrees were awarded in non-STEM fields (52%) than in STEM fields (48%).
But maybe students at these schools figure they don’t need STEM majors because after graduation they can simply waltz off to Wall Street, so they have the luxury of dabbling in whatever they want as undergrads ? Well, maybe. But at many leading public universities, the pattern is similar. At UC Berkeley, 42% STEM majors. At UCLA, 35%. At UVA, 36%. At Michigan, 40%. At UNC Chapel Hill, 25%.
The exact figures vary depending on things like whether the school offers engineering and, if so, how large is its engineering school (if it’s a separate school; some aren’t), whether it has a nursing school, etc. But the point is at all these schools there are more non-STEM than STEM majors.
It could well be that there’s been an uptick in STEM majors in recent years; if so, I’d like to see some data. But my sense is that most of the hand-wringing from humanities faculty comes not from an inability to fill undergraduate classrooms. The crisis they face is that their Ph.D. programs are faltering because there’s not much of a market for newly minted humanities Ph.D.s anymore due to the paucity of entry-level hiring in the humanities, and the kinds of students who in the past might have pursued humanities Ph.D.s are aware of it, and staying away in droves. And that is more the consequence of economic pressures within academia than anything else. Science, medicine, and engineering faculties can fund a lot of their costs (including grad students) through research grants from external sources, and top research universities are very good at snaring these kinds of grants, in many cases to the tune of hundreds of millions annually, in a few cases topping $1 billion annually. That kind of money just isn’t available in the humanities. So, to put it crassly, STEM fields are often profit centers for universities, while humanities fields are sinkholes of costs, and the universities are under a lot of financial strain and need to invest wisely. Consequently, when budgets and entry-level faculty hiring lines get allocated, more of that money will go to the STEM disciplines because STEM hiring offers a better ROI to the university. Also, because they are unable to generate substantial external grant money, costly humanities grad programs become more difficult to justify, given that they’re contributing to a glut of newly minted Ph.D.s who are unlikely to find tenure-track positions, or any work at all, in their field of expertise. Less entry level hiring in the humanities => less work for newly minted humanities Ph.D.s => less reward for earning a humanities Ph.D. => less demand for seats in humanities Ph.D. programs => faltering humanities graduate programs => shrinkage or elimination of many humanities graduate programs => even less need for entry-level hiring in the humanities. It’s a vicious cycle, and it goes on even if demand for undergraduate humanities classes remains strong.
