Bans on teenagers’ social media use are gathering pace worldwide. Their proponents claim that social media bans will improve young people’s mental health, but what evidence supports these claims?

In this guest editorial, Neff Lind explains why she and her colleagues doubt that social media bans will work, and how bans should be evaluated to determine whether they have any positive effects.
