One of the most striking examples of this epistemic closure among liberal writers are their forays into "explanatory journalism." The idea that many people might like clear, smart explanations of what's going on in the news certainly has merit. But the tricky thing with "explaining" the news is that in order to do so fairly, you have to be able to do the mental exercise of detaching your ideological priors from just factually explaining what is going on. Of course, as nonliberal readers of the press have long been well aware, this has always been a problem for most journalists. And yet, the most prominent "explanatory journalism" venture has been strikingly bad at actually explaining things in a nonbiased way.
I am, of course, talking about Vox, the hot new venture of liberal wonkblogger extraordinaire Ezra Klein. It was already a bad sign that his starting lineup was mostly made up of ideological liberals. And a couple months in, it's clear that much of what passes for "explanation" on Vox is really partisan commentary in question-and-answer disguise.
And the troubling thing is, I don't think the people at Vox are even aware that that's what they're doing.
Consider this selection of Voxplainers on ObamaCare. "Millions of Americans are paying less for ObamaCare than cable"; "The best evidence we have that ObamaCare is working"; "Kathleen Sebelius is resigning because ObamaCare has won"; "The right can't admit that ObamaCare is working." (The URL slug on the last one: ObamaCare Derangement Syndrome.) Hmmm..
Or take another, related topic: Single-payer health care. What are the arguments for or against single payer? That's a complex topic! Thankfully Vox's Sarah Kliff, former health policy reporter at The Washington Post and a noted progressive, is here to explain. Her post on the topic which purports to list the arguments against single-payer does not mention the fact that cancer survival rates and other positive health outcomes are significantly higher in non-single-payer countries than in single-payer countries. It seems relevant. The point is not whether or not single payer is wrong, or that the cancer survival rate point is decisive. The point is that a prominent, talented liberal writer on health policy, asked to make an objective list of arguments against single payer, cannot do justice to the job.
Or take the alleged loss by the IRS which imposes onerous archiving requirements on all large companies of certain important emails related to the agency's targeting of conservative political groups. It certainly looks bad for the IRS. But it's really conservatives' fault, says Vox: The IRS scandal shows the IRS needs a bigger budget. Never mind the fact that the IRS already has a $2.4 billion IT budget and countless companies are able to archive emails with much smaller budgets, or that the IRS had a contract with an email backup company. Never mind that the argument for a higher budget is based on the notion that IRS applications rose dramatically before the scandal, which is, um, not true, even according to the liberal website Politifact. Again, the point isn't to litigate the IRS issue. The point is that Vox often looks more like a right-wing caricature of what a partisan media outlet dressed up as an explainer site would look like, rather than an actual explainer site.
There is no doubt that Klein and Vox are earnest. They are not engaged in some vast conspiracy to deceive the American public and surreptitiously plant liberal ideas in Americans' brains. Instead, Vox just contains a disturbing amount of, well, derp. (It's great at sports explainers, though!)
Another symbol of growing epistemic closure on the left is The New Republic, which, under new ownership, has gone from being an idiosyncratic magazine critiquing liberalism almost as often as endorsing it to becoming a liberal mouthpiece, and now has decided to get into the explanatory journalism game. The name of their new vertical? "QED." The jokes write themselves.
Increasingly, liberal writers have been drinking their own Kool-Aid. They really believe they are the "reality-based community."
