A Conversation?

A propos Cheryl's earlier post and MT's comments here, read this post by Julian Sanchez (via Sullivan), although he's speaking to Frum's firing from AEI. Here's a paragraph from the Sanchez post:

In the original post I suggested that the cocktail party attack itself might be a form of projection on the part of folks who are, at some level, acutely aware that their own careers depend on hewing pretty close to a party line. But I think there’s something else going on here too. One of the more striking features of the contemporary conservative movement is the extent to which it has been moving toward epistemic closure. Reality is defined by a multimedia array of interconnected and cross promoting conservative blogs, radio programs, magazines, and of course, Fox News. Whatever conflicts with that reality can be dismissed out of hand because it comes from the liberal media, and is therefore ipso facto not to be trusted. (How do you know they’re liberal? Well, they disagree with the conservative media!) This epistemic closure can be a source of solidarity and energy, but it also renders the conservative media ecosystem fragile. Think of the complete panic China’s rulers feel about any breaks in their Internet firewall: The more successfully external sources of information have been excluded to date, the more unpredictable the effects of a breach become. Internal criticism is then especially problematic, because it threatens the hermetic seal. It’s not just that any particular criticism might have to be taken seriously coming from a fellow conservative. Rather, it’s that anything that breaks down the tacit equivalence between “critic of conservatives and “wicked liberal smear artist” undermines the effectiveness of the entire information filter. If disagreement is not in itself evidence of malign intent or moral degeneracy, people start feeling an obligation to engage it sincerely—maybe even when it comes from the New York Times. And there is nothing more potentially fatal to the momentum of an insurgency fueled by anger than a conversation. A more intellectually secure conservatism would welcome this, because it wouldn’t need to define itself primarily in terms of its rejection of an alien enemy. [my highlighting].
