“The tragedy in Charleston last week will no doubt lead to more discussion of several important and recurring issues in American culture—particularly racism and gun violence—but these dialogues are unlikely to bear much fruit until the nation undertakes a serious self-examination. Decrying racism and gun violence is fine, but for too long America’s social dysfunction has continued to intensify as the nation has ignored a key underlying pathology: anti-intellectualism,” writes David Niose in Psychology Today.

America is killing itself through its embrace and exaltation of ignorance, and the evidence is all around us. Dylann Roof, the Charleston shooter who used race as a basis for hate and mass murder, is just the latest horrific example. Many will correctly blame Roof’s actions on America’s culture of racism and gun violence, but it’s time to realize that such phenomena are directly tied to the nation’s culture of ignorance.

In a country where a sitting congressman told a crowd that evolution and the Big Bang are “lies straight from the pit of hell,” where the chairman of a Senate environmental panel brought a snowball into the chamber as evidence that climate change is a hoax, where almost one in three citizens can’t name the vice president, it is beyond dispute that critical thinking has been abandoned as a cultural value. Our failure as a society to connect the dots, to see that such anti-intellectualism comes with a huge price, could eventually be our downfall.
