Is Social Media Destroying a Generation?

“Girls' rates of depression and anxiety doubled between 2010 and 2020 across the US, UK, Canada, and Australia simultaneously. That pattern follows smartphone adoption and social media penetration, not economic cycles, political events, or any other candidate explanation. The cross-national, cross-demographic simultaneity is exactly the pattern a single cause would produce.”

“Social media is specifically engineered to exploit the adolescent brain's sensitivity to social approval. Infinite scroll and notification design were built to maximize engagement, not wellbeing. Meta's own internal research showed the company knew Instagram was harmful to teenage girls' body image and mental health — and chose continued growth over remediation.”

“The most rigorous pre-registered studies — including Przybylski's work on 350,000 teenagers — find effects of social media on wellbeing smaller than wearing glasses or eating potatoes. The effect sizes largely disappear when controlling for prior mental health history, socioeconomic factors, and reverse causality: depressed teenagers spend more time online.”

“Mental health deteriorated across the same period in communities with minimal smartphone access, and improved in some communities with heavy use. That pattern is inconsistent with a simple screen-time story and consistent with economic precarity, housing insecurity, academic pressure, and pandemic disruption as primary causes.”
