This seemed like a good Valentine's Day post in honor of all the morons I've ever heard use dating metaphors to describe the academic job market. This study seems to have been secretly co-authored by the noted sociologist Captain Obvious. I mean what was their fucking Null Hypothesis? That institutional prestige has no bearing on how people see you? That higher teaching loads have no discernible effect on research output? Because that makes sense.
That said, I do think it's worth a glance. I suppose if it gets some of the bigger morons in the profession thinking about the structural inequalities in academic hiring, it might end up being worthwhile.
