Est-ce que les téléphones intelligents sont en train de détruire une génération? Quelques chiffres édifiants.
More comfortable online than out partying, post-Millennials are safer, physically, than adolescents have ever been. But they’re on the brink of a mental-health crisis.The shift is stunning: 12th-graders in 2015 were going out less often than eighth-graders did as recently as 2009. But only about 56 percent of high-school seniors in 2015 went out on dates; for Boomers and Gen Xers, the number was about 85 percent. Across a range of behaviors—drinking, dating, spending time unsupervised— 18-year-olds now act more like 15-year-olds used to, and 15-year-olds more like 13-year-olds. Childhood now stretches well into high school. The number of teens who get together with their friends nearly every day dropped by more than 40 percent from 2000 to 2015; the decline has been especially steep recently. It’s not only a matter of fewer kids partying; fewer kids are spending time simply hanging out.
