David Tufte at VoluntaryXchange has a great post explaining why the university political climate tends to be this way. He writes:
Here's five thougtful links about why - on average - professors hold the poltical views they do.
It all starts with an op-ed piece entitled "An Academic Question" in the New York Times by future Nobel Prize winner Paul Krugman. He points out that:
...today's Republican Party - increasingly dominated by people who believe truth should be determined by revelation, not research - doesn't respect science, or scholarship in general. It shouldn't be surprising that scholars have returned the favor by losing respect for the Republican Party.
I work with a lot of academics who take the idea of revelation through faith very seriously, and while I don't side with their religion, I can't see Krugman's claim as anything other than blinkered bigotry. Important blinkered bigotry though, because Krugman has the guts to say in print what a lot of academics use for an intellectual crutch to save themselves the trouble of engagement with the other side.
