An Academic Question (Paul Krugman column)

by Paul Krugman

It's a fact, documented by two recent studies, that registered Republicans and self-proclaimed conservatives make up only a small minority of professors at elite universities. But what should we conclude from that?

Conservatives see it as compelling evidence of liberal bias in university hiring and promotion. And they say that new "academic freedom" laws will simply mitigate the effects of that bias, promoting a diversity of views. But a closer look both at the universities and at the motives of those who would police them suggests a quite different story.

Claims that liberal bias keeps conservatives off college faculties almost always focus on the humanities and social sciences, where judgments about what constitutes good scholarship can seem subjective to an outsider. But studies that find registered Republicans in the minority at elite universities show that Republicans are almost as rare in hard sciences like physics and in engineering departments as in softer fields. Why?
