The short version

Prominent advocates attribute rising rates of teen anxiety, depression, and suicide to a transition from play-based to phone-based childhoods starting around 2010.
Multiple large-scale psychological studies and meta-analyses have found only small, inconsistent, or statistically negligible correlations between social media use and poor adolescent mental health.
Data from Europe and recent declines in U.S. teen suicide rates since 2017–2018 complicate arguments of a direct causal link between screen time and mental health crises.

Advocates like Jonathan Haidt argue that the shift from play-based childhood to phone-based childhood between 2010 and 2015 caused a youth mental health crisis characterized by rising anxiety, depression, and suicide.[Hacker News]

A review by the National Academies of Sciences, Engineering, and Medicine found no consistent pattern across adolescent samples regarding social media's impact on sadness, anxiety, or depression.[Hacker News]
U.S. teen suicide rates have begun to fall since 2017–2018, and European suicide rates dropped despite the simultaneous adoption of social media, complicating direct causal claims.[Hacker News]
Modern youth show statistical improvements over past decades in areas such as physical safety, lower rates of smoking and drinking, and reduced physical and sexual violence.[Hacker News]

Individual-level correlational studies may fail to capture the true harms of social media if its widespread adoption acts as a collective action problem, where opting out carries a heavy social cost.[Hacker News]
