Questions about the Internet’s deleterious effects on the mind are at least as old as hyperlinks. But even among Web skeptics, the idea that a new technology might influence how we think and feel—let alone contribute to a great American crack-up—was considered silly and naive, like waving a cane at electric light or blaming the television for kids these days. Instead, the Internet was seen as just another medium, a delivery system, not a diabolical machine. It made people happier and more productive. And where was the proof otherwise?
Now, however, the proof is starting to pile up. The first good, peer-reviewed research is emerging, and the picture is much gloomier than the trumpet blasts of Web utopians have allowed. The current incarnation of the Internet—portable, social, accelerated, and all-pervasive—may be making us not just dumber or lonelier but more depressed and anxious, prone to obsessive-compulsive and attention-deficit disorders, even outright psychotic. Our digitized minds can scan like those of drug addicts, and normal people are breaking down in sad and seemingly new ways.
