"Is Facebook Making Us Lonely?" asks novelist and columnist Stephen Marche in an excellent article in next month's Atlantic. "From Facebook to Twitter," he notes, "social media have made us more densely networked than ever. Yet for all this connectivity, new research suggests that we have never been lonelier (or more narcissistic)—and that this loneliness is making us mentally and physically ill."
In one rather striking survey Marche cites, the mean size of networks of personal confidants in the U.S. was shown to have "decreased from 2.94 people in 1985 to 2.08 in 2004." In 1985, he adds, "10 percent of Americans said they had no one with whom to discuss important matters, and 15 percent said they had only one such good friend. By 2004, 25 percent had nobody to talk to, and 20 percent had only one confidant."
