By the end of the 20th century, personal computers had entered our homes, the Internet was a global phenomenon, and almost identical worries were widely broadcast through chilling headlines: CNN reported that "Email 'hurts IQ more than pot'," the Telegraph that "Twitter and Facebook could harm moral values" and the "Facebook and MySpace generation 'cannot form relationships'," and the Daily Mail ran a piece on "How using Facebook could raise your risk of cancer." Not a single shred of evidence underlies these stories, but they make headlines across the world because they echo our recurrent fears about new technology.
These fears have also appeared in feature articles for more serious publications: Nicolas Carr's influential article "Is Google Making Us Stupid?" for the Atlantic suggested the Internet was sapping our attention and stunting our reasoning; the Times of London article "Warning: brain overload" said digital technology is damaging our ability to empathize; and a piece in the New York Times titled "The Lure of Data: Is It Addictive?" raised the question of whether technology could be causing attention deficit disorder. All of these pieces have one thing in common—they mention not one study on how digital technology is affecting the mind and brain. They tell anecdotes about people who believe they can no longer concentrate, talk to scientists doing peripherally related work, and that's it. Imagine if the situation in Afghanistan were discussed in a similar way. You could write 4,000 words for a major media outlet without ever mentioning a relevant fact about the war. Instead, you'd base your thesis on the opinions of your friends and the guy down the street who works in the kebab shop. He's actually from Turkey, but it's all the same, though, isn't it?
There is, in fact, a host of research that directly tackles these issues. To date, studies suggest there is no consistent evidence that the Internet causes mental problems. If anything, the data show that people who use social networking sites actually tend to have better offline social lives, while those who play computer games are better than nongamers at absorbing and reacting to information with no loss of accuracy or increased impulsiveness. In contrast, the accumulation of many years of evidence suggests that heavy television viewing does appear to have a negative effect on our health and our ability to concentrate. We almost never hear about these sorts of studies anymore because television is old hat, technology scares need to be novel, and evidence that something is safe just doesn't make the grade in the shock-horror media agenda.
The writer Douglas Adams observed how technology that existed when we were born seems normal, anything that is developed before we turn 35 is exciting, and whatever comes after that is treated with suspicion. This is not to say all media technologies are harmless, and there is an important debate to be had about how new developments affect our bodies and minds. But history has shown that we rarely consider these effects in anything except the most superficial terms because our suspicions get the better of us. In retrospect, the debates about whether schooling dulls the brain or whether newspapers damage the fabric of society seem peculiar, but our children will undoubtedly feel the same about the technology scares we entertain now. It won't be long until they start the cycle anew.
