The idea (found this article via Clarissa's blog) is that:
When white men do more service, women and people of color will have more time to engage in research. We do not have to level the playing field by asking people of color and women to act more like white men. We can level the playing field by asking white men to engage in their share of service, too.
This is from a faculty member where I teach, so I am a little embarrassed at how simplistic this sounds. On the face of it, it seems logical, right? There is a finite amount of service, a finite amount of time each person has, so if we shift the burden we will have more research from one demographic.
I am trying to imagine, though, a scenario in which we white men could do more service and magically make our non-white-male colleagues produce more research. It doesn't work like this. My female colleagues who produce ample amounts of research are also stars in service. A man from my department who has always done a lot of service, while also excelling research and teaching, is now a vice-chancellor, probably perpetuating the white male hegemony in administration in the process.
People who excel typically do so by excelling in more than one area. If those who excel are white men, then of course we should ask people of color and women to do the same thing. In my experience service is valued more in those who also do research, and much less in those who load up on service in order to have an excuse not to get their research done.
Look at the cv of her dissertation advisor. Should he have done even more service than he has done in his life? Would that have made some other person of a different race and gender into a distinguished professor?
[Update: Also, this takes away agency from those who would presumably benefit. Women and POC would have to wait around for the white men to start doing more service.]
