Megan McArdle: Mainstream Media Have Failed to Notice Their Own Disinformation Issue

From a Washington Post column by Megan McArdle headlined “Mainstream media have failed to notice their own disinformation issue”:

When it comes to information, we are no longer one nation, undivided. The problem has been developing at least since 2010, when Julian Sanchez noted the growing “epistemic closure” on the right.

“Reality is defined by a multimedia array of interconnected and cross promoting conservative blogs, radio programs, magazines, and of course, Fox News,” he wrote. “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.”
