I’ve written a bit lately about what I see as a systematic trend toward “epistemic closure” in the modern conservative movement. As commenters have been quick to point out, of course, groupthink and confirmation bias are cognitive failings that we’re all susceptible to as human beings, and scarcely the exclusive province of the right …Yet I can’t pretend that, on net, I really see an equivalence at present: As of 2010, the right really does seem to be substantially further down the rabbit hole.
Andrew Sullivan offers up some related links and commentary. I tend to agree with Sanchez and Sullivan, but I thought you all would be a good group to poll. Please offer up your opinion in the comments.
