These results offer clear evidence that 13, which is the current (and unenforced) minimum age for opening an account on social media platforms, is too low. Thirteen-year-olds should not be scrolling through endless posts from influencers and other strangers when their brains are in such an open state, searching for exemplars to lock onto. They should be playing, synchronizing, and hanging out with their friends in person while leaving some room in the input streams to their eyes and ears for social learning from their parents, teachers, and other role models in their communities.
