The tolerance of the left: When asked in a survey if they would discriminate against conservatives, the academic community freely admitted that they would gladly do so.

One question, according to the researchers, “asked whether, in choosing between two equally qualified job candidates for one job opening, they would be inclined to vote for the more liberal candidate (i.e., over the conservative).” More than a third of the respondents said they would discriminate against the conservative candidate. One respondent wrote in that if department members “could figure out who was a conservative, they would be sure not to hire them.”

Then there’s this:

Mr. Inbar and Mr. Lammers found that conservatives fear that revealing their political identity will have negative consequences. This is why New York University-based psychologist Jonathan Haidt, a self-described centrist, has compared the experience of being a conservative graduate student to being a closeted gay student in the 1980s.

In 2011, Mr. Haidt addressed this very issue at a meeting of the Society for Personality and Social Psychology — the same group that Mr. Inbar and Mr. Lammer surveyed. Mr. Haidt’s talk, “The Bright Future of Post-Partisan Social Psychology,” caused a stir. The professor, whose new book “The Righteous Mind” examines the moral roots of our political positions, asked the nearly 1,000 academics and students in the room to raise their hands if they were liberals. Nearly 80 percent of the hands went up. When he asked whether there were any conservatives in the house, just three hands — 0.3 percent — went up.

This is “a statistically impossible lack of diversity,” Mr. Haidt said.

What is horrifying to me is that this prejudiced behavior is taking place within our society’s supposingly most educated community., the place where thoughtful, rational debate is supposed to be cherished and honored. How can we have a just and fair-minded culture if our elite education system is home to this kind of close-minded and hateful bigotry?
