Surprise? Right Wing Bloggers are Rigid and Insular

Conservatives are psychologically challenged - there is considerable research supporting that position [1] [2] [3]. So when I read at The Nation about new research suggesting that, relative to its liberal counterpart, the conservative blogosphere is especially inbred and insulated politically and inflexible and hierarchical in technical terms, I am inclined to attribute that to the psychological characteristics that lead people to be conservatives in the first place. The authors of the study are simply too PC to say so.
