New data on device restrictions in schools shows they don't meaningfully improve student mental health outcomes, challenging the assumption that removing phones from classrooms addresses the underlying drivers of youth anxiety and depression. The problem isn't proximity to devices during school hours, but how students' entire social and information environments have been restructured around phones—a change that can't be undone by a seven-hour ban. Any intervention addressing youth mental health will need to operate at a systemic level, not the device level.
