In 1971, the psychologist Philip Zimbardo spearheaded the Stanford prison experiment to show how the hierarchy of the penitentiary system could turn otherwise reasonable men into monsters. Now, Zimbardo has identified a new threat to mankind: the Internet. Excessive video game use and porn consumption, Zimbardo says, is turning modern young men into limp, loveless losers. It’s a theory he’s pushed with increasing urgency over the past several years. In 2011, Zimbardo delivered a TED talk titled “The Demise of Guys?” The next year, he penned an e-book based on the talk titled The Demise of Guys, no more question mark. And this month, Zimbardo released his full-length tract: Man (Dis)connected: How Technology Has Sabotaged What It Means to Be Male, and What Can Be Done.
