In a paper they wrote about the ideological leanings of blog readers and news-watchers, Henry Farrell, Eric Lawrence and John Sides find that conservatives tend to read only conservatives blogs, while most liberals read only left-leaning blogs. That's not a huge surprise. They also find this:
Those few people who read both left wing and right wing blogs are considerably more likely to be left wing themselves; interpret this as you like.
I'm going to go ahead and interpet it: Liberals are more interested in listening to opposing points of view than are conservatives. Now, most people in general do not like listening to opposing views, but those who do are overwhelmingly on the left. I'm going to wallow in smug self-satisfaction for a few minutes, then go over to the Corner to see if anybody has a rebuttal.
