Is Social Media Destroying a Generation?
Teen depression doubled between 2010 and 2020 in the US, UK, Canada, and Australia — tracking smartphone adoption. Haidt says social media is the driver; critics say the data doesn't prove it. Correlation — or crisis? Two debaters, opposing sides — you score who makes the stronger case.

What's at stake
If phones are genuinely the problem, restricting them is clear public health policy. If the evidence doesn't hold, the panic crowds out research into what's actually going wrong.
The Matchup
The Positions
A 10-year, cross-national spike in teen depression tracks the smartphone's arrival too precisely to be coincidence. The mechanism is well understood: social comparison, sleep disruption, and attention fragmentation are documented effects of the infinite-scroll design.
- Girls' rates of depression and anxiety doubled between 2010 and 2020 across the US, UK, Canada, and Australia simultaneously. That pattern follows smartphone adoption, not economic cycles or any other candidate explanation.
- Social media is specifically engineered to exploit the adolescent brain's sensitivity to social approval; the infinite-scroll and notification design was built to maximize engagement, not wellbeing, with internal research at Meta showing the company knew of the harm.
- The solutions are achievable and demonstrably work: age verification, phone-free schools, and redesigning feeds away from social comparison have shown measurable wellbeing improvements where tried. The only obstacle is political will.
Debater: To be announced
The correlation exists; the causation doesn't hold up to scrutiny, and blaming screens lets us off the hook for the real drivers of youth distress.
- 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 disappear when you control for prior mental health history and socioeconomic factors.
- Mental health deteriorated across the same period in communities with minimal smartphone access and improved in some with heavy use; that pattern is inconsistent with a simple screen-time story and consistent with economic precarity and pandemic disruption.
- Blaming the phone is convenient for everyone: politicians don't have to fund mental health services, parents don't have to examine household stress, and tech companies pivot to 'safety' features without substantive change. The moral panic serves powerful interests.

“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.”

Should Billionaires Exist?
The US had 13 billionaires in 1982; it has over 800 today. Billionaires gained $5 trillion during the COVID pandemic alone. Is extreme wealth a reward for value creation — or proof of a rigged system? Two debaters, opposing sides — you score who makes the stronger case.
