48. The two-body problem.

Graduate school tends to delay marriage (see Reason 15), but if you decide to go to graduate school, you will likely spend many years as a graduate student among other graduate students. Not surprisingly, grad students sometimes fall in love and marry each other. They can be a great support to one another as they together go through the struggles of grad school on a shoe-string budget, but their marriage has created what in academic circles is commonly referred to as “the two-body problem.” It is hard enough for one human being to finish graduate school and secure an academic position; you can imagine how hard it is for two people.

Let us say that you marry a fellow graduate student and both of you manage to complete your PhDs. (The fact that you have each other’s support may make that more likely.) Now it is time for you both to find jobs. First of all, there are very few jobs (see Reason 8), and the available jobs are probably nowhere near where you are now (see Reason 16). Having spent years of your lives devoting yourselves to your respective disciplines, you are both heavily invested in your fields. At the same time, neither of you is better qualified for anything other than being a professor (see Reason 29). You will be very lucky if either of you is offered an assistant professorship; you will be extraordinarily lucky if both of you are. In that unlikely event, if you are offered a job in Texas and your spouse is offered a job in Minnesota, which one of you is going to accept the position? Academic jobs are so precious that there are married couples who work hundreds of miles away from each other, but do you really want to do that? An alternative is to move with your spouse and hope that you will land a job within commuting distance of your new home. Another is for one of you to start from scratch in a new profession.
