Episode notes
Big Tech Sued For Designing Addiction
- Multiple U.S. lawsuits claim Meta and YouTube purposely used persuasive design like endless scroll and algorithms to prioritise engagement over wellbeing.
- Plaintiffs argue this design addicting the brains of children caused mental health problems, citing internal research and feature examples like the like button.
Legal Hurdles Around Proving Social Media Harm
- Proving causation and 'social media addiction' will be legally difficult because addiction lacks formal diagnostic consensus and mental health is multifactorial.
- Defendants will contest addiction legitimacy, point to safety features, and demand proof social platforms caused the harms.
Use Home Rules To Counter Platform Design
- Parents are not powerless: set clear household rules about screens and discuss persuasive design and algorithms with kids.
- Emphasise sleep, movement and open conversations instead of relying on platforms' safety features.
