> But the smartphone thesis has a few weak spots. It’s not just middle schoolers and high schoolers whose performance is declining; it’s also kids in elementary school. Phone use has certainly increased among young children, but not to the ubiquitous proportions of adolescents. And even though smartphone use is almost universal, the learning losses have not been. High-achieving kids are doing roughly as well as they always have, while those at the bottom are seeing rapid losses.
My kids are allowed to have screen time, but with limits. Most of their friends have similar arrangements. It doesn't seem to stop them from enjoying reading. When you're limited to an hour of screen time a day, there's still 23 hours to do other stuff.
