Meta hides mental health research on its platforms, lawsuit claims

Meta is accused of suppressing internal research that found Facebook and Instagram could harm users’ mental health, according to newly unsealed court filings in a US class action lawsuit.

The lawsuit, filed by school districts against Meta and other social media firms, alleges Meta halted a 2020 study after it showed that users who deactivated the platforms reported less depression, anxiety, and loneliness.

Internal documents cited in the filing claim Meta staff acknowledged the study’s findings were valid, but chose not to publish the results, instead citing external media narratives.

The plaintiffs also allege Meta hid known product risks from users and authorities, designed ineffective youth safety features, and prioritized growth over safety.

Other claims include Meta allowing repeat offenders to remain on the platform, and stalling efforts to protect minors.

Meta disputed the allegations, saying its safety measures are effective and that the cited documents are being misrepresented.

A court hearing on the matter is scheduled for January 26 in California.

🧠 Food for thought

Implications, context, and why it matters.

Judge Yvonne Gonzalez Rogers is a federal judge. She ruled that Section 230 of the Communications Decency Act (a law that shields platforms from suits over user posts) does not cover Meta’s design choices, including inadequate parental controls and the timing and clustering of notifications of its content 1 2. The court also said platform features can count as products under product liability law, including age verification and account deletion barriers 1.
If that reading holds at the January 26 hearing, Meta could face legal risk tied to alleged addictive design features instead of user content, and over 200 school districts joined the case within one year with many claims by state attorneys general (the top law enforcement officials in each state) moving forward under consumer protection laws 1 2.
The Kids Online Safety Act (KOSA) returned on May 14, 2025 with bipartisan backing from Senate leadership after a 91-3 Senate vote in the prior Congress, and it stalled in the House over First Amendment (free speech) concerns 3. The new draft limits government enforcement tied to protected speech while keeping safeguards such as account deletion, privacy protections, and parental controls 3.
Vendors of compliance tools include age verification technology (to verify or estimate a user’s age), safety-by-design audit tools (to assess whether features minimize harm), and parental control systems (to help caregivers manage minors’ accounts). If KOSA passes this Congress, platforms will need solutions immediately, and late entrants will lose an early lead 3. Apple has endorsed the bill 4.
