A federal court in Northern California found that Meta hid internal studies and research data showing negative impacts, particularly on Instagram users' self-image and psychological well-being.

What happened

A coalition of more than 40 U.S. states sued Meta, alleging that its Facebook and Instagram platforms were designed to induce dependency and cause significant damage to youth's physical and mental health.

A federal court in Northern California found that Meta deliberately hid evidence, including internal studies and research data detailing the negative impact of its platforms, especially Instagram, on adolescents' self-image and psychological well-being.

According to court documents from an unredacted lawsuit filed by U.S. school districts, Meta had scientists develop the 'Mercury' project in 2020 to assess the effects of deactivating Facebook and Instagram. The study found that people who stopped using Facebook for a week reported feelings of lower depression, anxiety, loneliness, and social comparison.

Reported impact

Meta allegedly halted the Mercury project and declared internally that the study's negative conclusions were contaminated by media narrative around the company, despite finding a connection between its platforms and negative effects on people's lives.

Prosecutors argue this is the most important legal initiative to counter the impact of social media on youth mental health and force structural changes to the platforms' core features.

Index analysis

The court's preliminary findings suggest Meta acted to prevent disclosure of relevant information and created a presumption of bad faith, indicating the company was aware of risks inherent in its product design but chose to prioritize user engagement and profit over the safety of minors.

Governance controls

Meta stated in its defense that it introduced significant tools and resources to protect young users and their families, and denied any intention to conceal data or promote unsafe environments.
