Teens today are more likely to be lonely, depressed and immature than any previous generation, according to analysis published in The Atlantic. According to Jean M. Twenge, a professor of psychology at San Diego State University who has been researching generational differences for 25 years, the culprit is the smartphone.
Why it matters: Physically, the iGen are safer than previous generations, but psychologically they are much more vulnerable to mental illness, including serious upticks in depression and suicide, according to the report. "There is compelling evidence that the devices we've placed in young people's hands are having profound effects on their lives—and making them seriously unhappy," writes Twenge.
What's at stake: Smartphones aren't going anywhere, and as Twenge points out, of those who suffer from depression at a young age, at least half become depressed again later in life.
