The country has gone without a Senate-confirmed surgeon general for more than a year, yet the office continues producing pronouncements. On May 20, the Office of the Surgeon General released an advisory on screen use in children and adolescents.

The screen-use advisory states explicitly that its findings are not the product of a formal systematic review. By the issuing agency's own standards, it is not a scientific document. But it frames the issue with an authority that makes moral panic sound like public health. 

Almost everything we know about children and screens comes from cross-sectional research, examining correlations at a single snapshot in time. It is difficult to determine, without longitudinal data, let alone randomized control trials, what the directionality is of associations between screen time and mental health. Do screens cause worse mental health? Or do children with poor mental health spend more time on screens, seeking social support online?

The advisory is candid about this when it addresses the science directly. It acknowledges that most available evidence is correlational, that findings vary by age, content, and context, and that studies have reported positive, negative, mixed, and null effects.
