# Jonathan Haidt Brings New Evidence to the Battle Against Social Media | Hard Fork Source: https://www.youtube.com/watch?v=tZSteN2g5yM Recap page: https://rapidrecap.app/video/tZSteN2g5yM Generated: 2026-01-16T22:03:09.98+00:00 --- ## Quick Overview Jonathan Haidt presented new research arguing that the evidence for social media causing harm to children is now overwhelming, moving beyond mere correlation to causation through various mechanisms like sexual harassment and sextortion, while hosts Kevin Roose and Casey Newton shared numerous examples of listeners successfully building functional software using Claude Code, demonstrating the empowering, anti-slop potential of generative AI tools. **Key Points:** - Haidt contends that evidence for social media causing harm is now 'overwhelming,' citing true experiments showing depression decreases after getting off social media for at least a week. - Meta's internal research, exposed via lawsuits, revealed high rates of harm mechanisms for kids, including about 15% experiencing sexual harassment weekly and the standout issue of 'sextortion.' - Haidt separates the 'historical population question' (proving social media caused the post-2012 mental health increase) from the 'product safety question' (which he confirms with 99.9% confidence: social media is hurting millions of kids). - Haidt blames the companies for creating 'collective action traps' that prevent parents from opting out, asserting blame falls on them, not on parents or teachers. - Listeners demonstrated the power of Claude Code by building functional products, such as Sarah Haggard's full-featured book recommendation website, sarahbooks.com, despite having no prior coding experience. - Welder Joe, without formal training, built his own business infrastructure using Claude Code, including an MCP server acting as a personal assistant to track jobs and create estimates, emphasizing this is 'anti-slop' empowerment. - Haidt plans to focus advocacy on social media first, stating that if they cannot win consensus on social media harms, they 'just give up on AI,' viewing the current fight as a strategic prerequisite for addressing future AI threats. **Context:** Tech columnist Kevin Roose and Casey Newton of Platformer host Jonathan Haidt, author of the mega-bestseller 'The Anxious Generation,' to discuss his new research addressing criticisms about correlation versus causation in social media's effect on teen mental health. The conversation also pivoted to the hosts' recent experiment involving listeners using Anthropic's Claude Code to build software, contrasting the dangers of social media with the empowering creation capabilities of new AI agents. ## Detailed Analysis Jonathan Haidt returned to Hard Fork to present new research with Zachary Roush, asserting that the debate over whether social media causes depression in youth is settled, declaring the evidence for causation 'overwhelming,' supported by true experiments and internal Meta data revealing mechanisms like frequent sexual harassment and sextortion experienced by users. Haidt distinguishes between proving the historical population-level cause and confirming that the product itself is unsafe for children, stating he is 99.9% confident in the latter. He attributes the widespread adoption of harmful tech to 'collective action traps' and places blame squarely on the companies, not on parents or regulators. Haidt noted his advocacy shift, citing a successful meeting with French President Macron who promised to push for EU-wide action. Separately, hosts Kevin Roose and Casey Newton highlighted listener success stories using Claude Code, framing these projects as 'anti-slop' empowerment; examples included a welder building complex business tools and a user launching a functional public web app, Stash, demonstrating that non-coders can now build sophisticated software, which the hosts view as crucial for understanding the true pace of AI progress before the technology evolves into new threats like advanced AI companions. ### Social Media Harm & Causality - Evidence for causation is now 'overwhelming' via experiments and internal data - Mechanisms include sexual harassment (15% weekly rate) and sextortion - Haidt separates historical proof from current product safety confirmation. ### Advocacy and Policy Response - Haidt finds doors open to lawmakers globally, citing a commitment from Macron to push for EU-level restrictions - Proposed norms include no smartphone before high school and no social media before 16 - He views winning the social media fight as necessary groundwork before tackling AI threats. ### AI Coding Agent Empowerment - Listeners successfully built functional software using Claude Code, often with zero prior experience - Examples include Sarah Haggard's book recommendation site and Joe the welder's custom business infrastructure - Hosts frame this creation as 'anti-slop' and essential for understanding the current state of AI. ### Listener Creation Highlights - Gina designed a website with a 'MySpace profile' Easter egg - David Phillips turned his family's Christmas letter into an 80s text adventure game - Fay Bell built a 'wallpaper calculator' for her interior design business, eliminating manual calculations. ### Future Trajectory and Reflection - Haidt needs five years to judge the success of the Australian experiment on mental health metrics, but notes ancillary benefits like reduced harm already justify policy - Hosts note that adults, even tech employees, struggle to manage attention, confirming the scope of the problem beyond children.
