Psychologist Warns Social Media May Permanently Harm Teens’ Focus by Age 25

Excessive smartphone use among teenagers is jeopardizing their ability to concentrate—a crucial soft skill for long-term success—warns social psychologist Jonathan Haidt, who calls for urgent behavioral changes before the age of 25.

Jonathan Haidt, a New York University professor and author of "The Anxious Generation," highlighted the dangers of constant digital stimulation during a recent appearance on "The Oprah Podcast." He stated that teens' overuse of social media and smartphones is "shattering" their attention spans and may cause lasting cognitive damage.

According to 2021 data from Common Sense Media, teens aged 13 to 18 average eight hours and 39 minutes of screen time daily. The organization’s 2023 "Constant Companion" report also found that teens receive approximately 240 notifications and check their phones more than 100 times a day.

"It is urgent that you restore your brain," Haidt said, noting that by age 25 the brain’s frontal cortex—which governs focus and self-control—is largely developed, and by that point, getting your attention back becomes much harder.

The consequences extend beyond academics and employment. "Do you think any employer's going to find it useful to hire someone who can't focus on what they're supposed to focus on?" Haidt asked.

To rebuild focus, Haidt recommended a 30-day break from social apps, preferably with support from friends or family. He also suggested substituting screen time with reading, journaling, or outdoor activities.

Supporting this approach, Harvard psychiatrist Srini Pillay noted that listening to music, carefully chosen to avoid emotional disruption, can enhance concentration by reducing stress and cortisol levels.
