Because twin studies show genetic overlap, causal blame on screen-time weakens. Robust heritability of social media use and genetic correlations with well-being/anxiety mean observed harms may reflect shared predispositions, demanding higher evidentiary standards for causal regulation.
— This reframes legal and policy arguments about youth online safety, platform liability, and school/device restrictions by elevating confounding and individualized risk over blanket causation claims.
