It is an ambitious social experiment of our moment in history. Experts say it could accomplish something that parents, schools and other governments have attempted with varying degrees of success — keeping kids off social media until they turn 16.

Last year, France passed legislation that requires children under 15 to get a parent’s permission before getting a social media platform, but local media reports that technical challenges have led to a lack of enforcement. Norway is also hoping to enforce a strict minimum age of 15 to access social media.

The law sets a minimum age for users of platforms like TikTok, Instagram and X. How the restriction will be enforced online remains an open question.
