Social media takes up a huge chunk of kids’ lives. A 2024 study from Pew found that about half of U.S. teenagers are online “almost constantly.” It’s a big source of stress for parents too, and policing their kids’ actions on these platforms can take up a lot of time and energy. Also, there’s AI, and it’s showing up on social media as bots that are always available to talk. We’re going to get to all of that this week in our new series about what it’s like to be a kid on social media and the risks and rules that come with it. We call it “The Infinite Scroll.” We’re kicking things off with Eva Telzer, a professor of neuroscience and psychology at the University of North Carolina at Chapel Hill. Telzer told Marketplace’s Stephanie Hughes about the intensity of youngsters’ connection to their phones and its effects on how the kids are wired, which may last into adulthood.
