The Attack on Truth: We have entered an age of willful ignorance

Lee McIntyre in the Chronicle of Higher Education:

Humans have always held some wrongheaded beliefs that were later subject to correction by reason and evidence. But we have reached a watershed moment, when the enterprise of basing our beliefs on fact rather than intuition is truly in peril.

It’s not just garden-variety ignorance that periodically appears in public-opinion polls that makes us cringe or laugh. A 2009 survey by the California Academy of Sciences found that only 53 percent of American adults knew how long it takes for Earth to revolve around the sun. Only 59 percent knew that the earliest humans did not live at the same time as the dinosaurs.

As egregious as that sort of thing is, it is not the kind of ignorance that should most concern us. There is simple ignorance and there is willful ignorance, which is simple ignorance coupled with the decision to remain ignorant. Normally that occurs when someone has a firm commitment to an ideology that proclaims it has all the answers — even if it counters empirical matters that have been well covered by scientific investigation. More than mere scientific illiteracy, this sort of obstinacy reflects a dangerous contempt for the methods that customarily lead to recognition of the truth. And once we are on that road, it is a short hop to disrespecting truth.
