77. It attracts the socially inept.

Graduate school demands that you spend an immense amount of time alone (see Reason 69). It demands sustained interest in highly esoteric subjects. And it demands that you approach those esoteric subjects with the utmost seriousness. You can see how this environment would be attractive to people who are more comfortable in their own thoughts than in the company of others. This applies across academic disciplines. While some graduate students are involved in cutting-edge medical research, others are studying the subtle aspects of postwar Croatian cinema (see Reason 66). Oddly enough, the latter take their work as seriously as the former. Grad school can be compared to an endless fan convention at which all the participants cluster by genre or disciplinary interest, and where every individual is highly invested in a particular sub-sub-sub-genre.

In fact, graduate school is best suited for those who are fanatical, because devotion to one’s field (measured in terms of productivity) is what is rewarded (see Reason 38). The problem for most graduate students is that they are normal people. They do not thrive in prolonged isolation, and even though they may have an abiding interest in their subject of study, it does not amount to fanaticism. In the world in which they find themselves, however, they have to both co-exist and compete with the die-hard fans (see Reason 2). Earnest discussion of obscure topics, irrational in-group status jockeying, and competitive devotion may be fine for hobbyists at weekend conventions, but graduate school goes on for years. It does not take long to spot the odd characters who inhabit this environment, nor to see its effects on healthy personalities (see Reason 50). Keenly aware of the variety of people who manage to percolate through graduate programs, academic hiring committees rely on an old-fashioned test: how will a job candidate perform in a conversation over dinner?
