>The dumbing down of America is most evident in the slow decay of substantive content in the enormously influential media, the 30-second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance. As I write, the number-one videocassette rental in America is the movie Dumb and Dumber. “Beavis and Butthead” remain popular (and influential) with young TV viewers. The plain lesson is that study and learning—not just of science, but of anything—are avoidable, even undesirable.
