It is not like I give much credence to these types of tests, but the results are ironic nonetheless:
Mr. Rothman used statistical analysis to determine what factors explained how academics ended up working at elite universities. Marital status, sexual orientation and race didn't play a statistically significant role. Academic excellence, as measured by papers published and awards conferred, did. But the next best predictor was whether the professor was a liberal. To critics that argue his methodology is flawed, Mr. Rothman points out that he used the same research tools long used in courts by liberal faculty members to prove race and sex bias at universities. Liberals criticizing his methods may find themselves hoist by their own petard.
How is this for some pretty amazing reading:
Robert Brandon, a Duke University philosophy professor, is one liberal who has at least made an effort to explain why conservatives are seldom seen in academia. "We try to hire the best, smartest people available. If, as John Stuart Mill said, stupid people are generally conservative, then there are lots of conservatives we will never hire. Mill's analysis may go some way towards explaining the power of the Republican Party in our society and the relative scarcity of Republicans in academia."
The rest of John Fund's article is worth a read.
