The Short Version
The 2026 World Happiness Report directly contradicts this claim. The report documents significant associations between heavy social media use and lower youth wellbeing, particularly among girls and in English-speaking countries and Western Europe. While the report notes complexity — such as moderate use being associated with higher wellbeing than no use at all — and stops short of claiming causation, it repeatedly identifies meaningful negative patterns. Characterizing these findings as "no significant relationship" fundamentally misrepresents the report's conclusions.
