Saletan has some tips on how to avoid epistemic closure. Number ten:
Overcome your urges. Hogan [a Redstate.com blogger] refuses to analyze opposing arguments in detail, arguing that he lacks "the desire" to do so. Perhaps he should brush up on the tradition he purports to represent. Real conservatives understand that desire is a lousy way to run a society. You don't feel like working? Work. You don't feel like supporting the kids you fathered? Support them. You don't feel like challenging your biases? Challenge them. We're all vain and lazy. In the electronic echo chamber, it's easier than ever to shut out what you don't want to hear. Nobody will make you open the door and venture out. You'll have to do that yourself.
