Robert Proctor is a historian of science at Stanford who has pointed out a bizarre modern phenomenon: the coexistence of easily available factual information and ignorance. That is the subject of Clive Thompson's article in Wired:

He has developed a word inspired by this trend: agnotology. Derived from the Greek root agnosis, it is "the study of culturally constructed ignorance."

As Proctor argues, when society doesn't know something, it's often because special interests work hard to create confusion. Anti-Obama groups likely spent millions insisting he's a Muslim; church groups have shelled out even more pushing creationism. The oil and auto industries carefully seed doubt about the causes of global warming. And when the dust settles, society knows less than it did before.

"People always assume that if someone doesn't know something, it's because they haven't paid attention or haven't yet figured it out," Proctor says. "But ignorance also comes from people literally suppressing truth—or drowning it out—or trying to make it so confusing that people stop caring about what's true and what's not."

After years of celebrating the information revolution, we need to focus on the countervailing force: The disinformation revolution.

Thompson suggests that we need to develop more tools like Wikipedia to allow society as a whole to "build real knowledge through consensus," thereby allowing us to expose systematic lies for what they are.
