Conservatives in the Ivory Towers

Paul Krugman's speculations concerning why there are fewer conservative Republicans on university faculties are interesting. I doubt it's the whole story--not because there is bias in hiring, but because it is an even deeper question of values than simple career choice. (Roughly: In the current climate, open-mindedness and willingness to question authority have been defined as "liberal" values. Consider the research by John Jost and his colleagues, that made such a flap a couple years back.) But Krugman reminds us that truth and science are under attack.
