Dr. Helen Smith (wife of the redoubtable Instapundit) is a criminal psychologist--she notes a recent journal article which landed in her mailbox:

Getting back to the current regurgitation article on the same topic, Jost finds in his research that liberals scored higher on openness than conservatives, what a surprise! "Results revealed that all six of the openness facets were associated with liberalism rather than conservatism: openness values (r=-.48), aesthetics (r=-.32), actions (r=-.27), ideas (r=-.24), feelings (r=-.24) and fantasy (r=-.19)" (American Psychologist, October 2006, pg. 663). So liberals are more open to ideas, feelings, and actions than conservatives. Dr.Jost, why not try this hypothesis out in the real world beyond the ivory tower? If you want to find out if liberals are open to new ideas, actions, and feelings, I challenge you to do the following:

1) Post comments around on various lefty blogs such as FireDogLake, The Daily Kos or Alicublog. These comments should disagree with the view of the host or view of the blog or diary; for example, state that you support Israel at the Daily Kos, wonder if feminists who are against sexual harrassment should support Bill Clinton at FireDogLake, and/or politely stand up for colleagues at Alicublog who you feel have been treated unfairly just because they disagree with the views of the host. Now, check back to evaluate scores for these paragons of openness for their ideas, actions and feelings. If your comments have been troll-scored by the Kossacks, deleted by Jane Hamsher, or ridiculed by whoever runs the Alicublog, give an openness score of zero. Negative bonus points if you are called a douche, told to stay in your place so as not to "assail your betters," or have a racial slur thrown your way.

Yes, the tolerance of the left is truly legendary.  Look no further than Columbia University, for instance.
