Jonathan Haidt is a social psychologist who believes that your child’s smartphone is a threat to mental well-being. His book, The Anxious Generation: How the Great Rewiring of Childhood Is Causing an Epidemic of Mental Illness, hit the No. 1 spot on the New York Times’ best-seller list. This book has struck a chord with parents who have watched their kids sit slack-jawed and stock still for hours, lost in a welter of TikTok, Instagram, Snapchat, Twitch, Facebook, and more. He says:

I do a little demonstration. I ask people, suppose a demon came to us in the nineties with three magical boxes. And he said, “You can open as many as you want, but if you open a box, it’s going to take fifteen hours a week from you.”

The first box is the Internet. You get this amazing thing, but it’s going to take fifteen hours a week from you. Would you open it? Are you glad we have the Internet? Everyone is glad we opened that box. We think that time is worth it.

The next box is the smartphone. You open it up. It’s this incredible digital Swiss Army knife (of apps and functions). It’s going to take another fifteen hours a week. So now you’re up to thirty hours a week on this. Do you want it? Are you glad we have smartphones? At that point, most hands go up. The great majority of adults say, “Yeah, I’m glad we opened that box.” Now you’re at thirty hours a week.

Next there’s a third box: social media – Instagram, Facebook, Tumblr, TikTok. It’s going to be another fifteen hours a week. So now you’re up to forty-five hours a week. What do you think? Are you glad we opened that?

The great majority of people say, “I wish we hadn’t opened that one.” I’m not talking about keeping kids off the Internet. I’m talking about not allowing them … to give away their data, and some rights, to a company that does not have their interests at heart. That is using them as the product to sell to their customers who are the advertisers. That’s what I don’t want done to eleven, twelve, thirteen, fourteen-year-old kids.
