Gladwell on "Everything Bad"

The New Yorker: The Critics: Books: "Americans—at least, as measured by I.Q. tests—were getting smarter... I.Q. scores showed a steady upward trajectory, rising by about three points per decade... test scores have continued to rise—not just in America but all over the developed world... In the wonderfully entertaining “Everything Bad Is Good for You” (Riverhead; $23.95), Steven Johnson proposes that what is making us smarter is precisely what we thought was making us dumber: popular culture."
