This may be partly true, but I think that the roots of grade inflation—and, by extension, the overall ease and lack of seriousness in Harvard's undergraduate academic culture—run deeper. Understanding grade inflation requires understanding the nature of modern Harvard and of elite education in general—particularly the ambitions of its students and professors.
The students' ambitions are those of a well-trained meritocratic elite. In the semi-aristocracy that Harvard once was, students could accept Cs, because they knew their prospects in life had more to do with family fortunes and connections than with GPAs. In today's meritocracy this situation no longer obtains. Even if you could live off your parents' wealth, the ethos of the meritocracy holds that you shouldn't, because your worth as a person is determined not by clan or class but by what you do and whether you succeed at it. What you do, in turn, hinges in no small part on what is on your résumé, including your GPA.
Thus the professor is not just a disinterested pedagogue. As a dispenser of grades he is a gatekeeper to worldly success. And in that capacity professors face upward pressure from students ("I can't afford a B if I want to get into law school"); horizontal pressure from their colleagues, to which even Mansfield gave way; downward pressure from the administration ("If you want to fail someone, you have to be prepared for a very long, painful battle with the higher echelons," one professor told the Crimson); and perhaps pressure from within, from the part of them that sympathizes with students' careerism. (Academics, after all, have ambitions of their own, and are well aware of the vicissitudes of the marketplace.)
It doesn't help that Harvard students are creatively lazy, gifted at working smarter rather than harder. Most of my classmates were studious primarily in our avoidance of academic work, and brilliant largely in our maneuverings to achieve a maximal GPA in return for minimal effort. It was easy to see the classroom as just another résumé-padding opportunity, a place to collect the grade (and recommendation) necessary to get to the next station in life. If that grade could be obtained while reading a tenth of the books on the syllabus, so much the better.
Sometimes you didn't have to do even that much. One of the last papers I wrote in college was assigned in "The American West, 1780—1930." The professor handed out two journal articles on the theory and practice of "material history"—essentially, historical research based on the careful analysis of objects. We were told to go to the Peabody, Harvard's museum of archaeology and ethnology, where the professor had set out three pairs of objects from the frontier era. One object in each pair had been made by Indians, one by Europeans, and we were to write a ten-page paper that compared the objects in a given pair. Aside from the articles on material history and a general text, North American Indian Jewelry and Adornment, we were to use no sources.
I picked a Sioux war club and an American revolver with its carrying case. As I stood in the museum taking notes, the assignment seemed impossible. How could I eke out ten pages when I knew nothing about the provenance of the weapons or the significance of their markings?
Sitting at my desk two weeks later, I realized I had been wrong. The paper was pathetically easy to write—not despite the dearth of information but because of it. Knowing nothing meant I could write anything. I didn't need to do any reading, absorb any history, or learn anything at all.
Some excerpts give the flavor of what I came up with.
Chief Running Antelope's war club is less a weapon than a talisman of supernatural power … The club's red paint and eagle feather link the weapon and its holder to sacred, invisible worlds; the "H. A. Brigham" inscription, a 19th century version of the modern logo, reinforces the revolver's connection to a capitalist order in which weapons are mass-produced, rather than individually crafted … The case is clearly an impractical method of carrying the gun … it is, rather, an eminently practical method of displaying a gun, with the paradoxical corollary that the gun is displayed by not being displayed … The book-like case, with its gold leaf and intricate images, transforms the gun by containing its potential for violence …
By the time I had finished, I almost believed it. My professor must have too: the paper got an A.
Not every class was so easy. Those that were tended to be in history and English, classics and foreign languages, art and philosophy—in other words, in those departments that provide what used to be considered the meat of a liberal arts education. Humanities students generally did the least work, got the highest grades, and cruised academically, letting their studies slide in favor of time-sucking extracurriculars, while their science- and math-minded classmates sometimes had to struggle to reach the B-plus plateau.
The theory is often advanced that grade inflation is worst in the humanities because grading English essays and history papers is more subjective than marking problem sets and lab reports, and thus more vulnerable to student pressure and professorial weakness. There is a teaspoon of truth to that claim, I suppose. But I think the problem in the humanities, as with grade inflation in general, can be traced to the roots of elite America—and specifically to the influence of the free market.
