The Dumbest Generation? Don’t Be Dumb.

Really, don't we all know by now that finding examples of teens' and twentysomethings' ignorance is like shooting fish in a barrel? If you want to exercise your eye-rolling or hand-wringing muscles, take your pick. Two thirds of high-school seniors in 2006 couldn't explain an old photo of a sign over a theater door reading COLORED ENTRANCE. In 2001, 52 percent identified Germany, Japan or Italy, not the Soviet Union, as America's World War II ally. One quarter of 18- to 24-year-olds in a 2004 survey drew a blank on Dick Cheney, and 28 percent didn't know William Rehnquist. The world's most heavily defended border? Mexico's with the United States, according to 30 percent of the same age group. We doubt that the 30 percent were boastful or delusional Minutemen.

Like professors shocked to encounter students who respond with a blank-eyed "huh?" to casual mentions of fireside chats or Antietam or even Pearl Harbor, and like parents appalled that their AP-amassing darling doesn't know Chaucer from Chopin, Mark Bauerlein sees in such ignorance an intellectual, economic and civic disaster in the making. In his provocative new book "The Dumbest Generation: How the Digital Age Stupefies Young Americans and Jeopardizes Our Future (Or, Don't Trust Anyone Under 30)," the Emory University professor of English offers the usual indicators, grand and slight. From evidence such as a decline in adult literacy (40 percent of high-school grads had it in 1992; only 31 percent did in 2003) and a rise in geographic cluelessness (47 percent of the grads in 1950 could name the largest lake in North America, compared with 38 percent in 2002), for instance, Bauerlein concludes that "no cohort in human history has opened such a fissure between its material conditions and its intellectual attainments."

He is a little late to this party, of course. The old have been wringing their hands about the young's cultural wastelands and ignorance of history at least since admirers of Sophocles and Aeschylus bemoaned the popularity of Aristophanes ("The Frogs," for Zeussakes?!) as leading to the end of (Greek) civilization as they knew it. The Civil War generation was aghast at the lurid dime novels of the late 1800s. Victorian scholars considered Dickens, that plot-loving, sentimental ("A Christmas Carol") favorite, a lightweight compared with other authors of the time. Civilization, and culture high and low, survived it all. Can it survive a generation's ignorance of history? For those born from 1980 to 1997, Bauerlein lamented to us, "there is no memory of the past, just like when the Khmer Rouge said 'this is day zero.' Historical memory is essential to a free people. If you don't know which rights are protected in the First Amendment, how can you think critically about rights in the U.S.?" Fair enough, but we suspect that if young people don't know the Bill of Rights or the import of old COLORED ENTRANCE signs—and they absolutely should—it reflects not stupidity but a failure of the school system and of society (which is run by grown-ups) to require them to know it. Drawing on our own historical memory also compels us to note that philosopher George Santayana, too, despaired of a generation's historical ignorance, warning that "those who cannot remember the past are condemned to repeat it." That was in 1905.

A more fundamental problem is what Bauerlein has in mind by "dumbest." If it means "holding the least knowledge," then he has a case. Gen Y cares less about knowing information than knowing where to find information. (If you are reading this online, a few keystrokes would easily bring you, for the questions so far, vice president, former chief justice of the Supreme Court, North and South Korea, Lake Superior.) And it is a travesty that employers are spending $1.3 billion a year to teach basic writing skills, as a 2003 survey of managers found. But if dumb means lacking such fundamental cognitive capacities as the ability to think critically and logically, to analyze an argument, to learn and remember, to see analogies, to distinguish fact from opinion … well, here Bauerlein is on shakier ground.

First, IQ scores in every country that measures them, including the United States, have been rising since the 1930s. Since the tests measure not knowledge but pure thinking capacity—what cognitive scientists call fluid intelligence, in that it can be applied to problems in any domain—then Gen Y's ignorance of facts (or of facts that older people think are important) reflects not dumbness but choice. And who's to say they are dumb because fewer of them than of their grandparents' generation care who wrote the oratorio "Messiah" (which 35 percent of college seniors knew in 2002, compared with 56 percent in 1955)? Similarly, we suspect that the decline in the percentage of college freshmen who say it's important to keep up with political affairs, from 60 percent in 1966 to 36 percent in 2005, reflects at least in part the fact that in 1966 politics determined whether you were going to get drafted and shipped to Vietnam. The apathy of 2005 is more a reflection of the world outside Gen-Yers' heads than inside, and one that we bet has changed tack with the historic candidacy of Barack Obama. Alienation is not dumbness.

Bauerlein is not the first scholar to pin the blame for a younger generation's intellectual shortcomings on new technology (television, anyone?), in this case indicting "the digital age." But there is no empirical evidence that being immersed in instant messaging, texting, iPods, videogames and all things online impairs thinking ability. "The jury is still out on whether these technologies are positive or negative" for cognition, says Ken Kosik of the University of California, Santa Barbara, codirector of the Neuroscience Research Institute there. "But they're definitely changing how people's brains process information." In fact, basic principles of neuroscience offer reasons to be optimistic. "We are gradually changing from a nation of callused hands to a nation of agile brains," says cognitive scientist Marcel Just of Carnegie Mellon University. "Insofar as new information technology exercises our minds and provides more information, it has to be improving thinking ability."
