Class action lawsuit documents from US school districts reveal that Meta concealed internal research suggesting that "stopping Facebook use is good for your health."
Meta is once again embroiled in controversy over concealing research data. According to a Reuters report, in a class-action lawsuit filed by multiple school districts against the social media giant in the United States, an unedited court document alleges that Meta concealed research findings that users who stopped using Facebook experienced reduced feelings of depression, anxiety, and loneliness, and even deliberately suspended related internal investigations. The lawsuit accuses the tech giant of knowingly concealing the health risks posed by its platform from users. "Project Mercury," which confirmed negative impacts, is suspected of being deliberately aborted. The research project, codenamed "Project Mercury," began in 2020 as a collaboration between Meta scientists and Nielsen, investigating the specific effects of "stopping" Facebook use on users. The lawsuit alleges that when research data showed "mental health benefits of leaving Facebook," Meta not only shut down the project but also chose not to publish the results, even labeling these findings as biased and contaminated by "existing media narratives." However, internal documents reveal differing opinions among Meta employees. Researchers explicitly stated, "Nielsen's research does indeed show the causal impact of Facebook on social comparisons." Even more startlingly, an internal employee likened this situation to past practices in the tobacco industry—"like conducting research that discovers cigarettes are harmful and then hoarding that information." This is reminiscent of energy giants like Shell and Exxon, who discovered the link between fossil fuels and climate change in the 1980s but chose to conceal it. Meta retaliates: Citing out of context. Facing the accusations, a Meta spokesperson issued a statement to Reuters, saying, "The full record will show that for over a decade we have listened to parents, researched critical issues, and made substantial changes to protect teenagers (such as Instagram's teen accounts)." Meta emphasized, "We strongly disagree with these allegations; the content relies on out-of-context quotations and erroneous viewpoints." Meta is currently seeking to have the court remove the underlying documents supporting these allegations, claiming the plaintiff's request for declassification is too broad. The related hearing is scheduled for January 26, 2026, in the Northern District of California District Court. The global wave of "bans on social media for minors" is not the first time Meta has been accused of concealing harmful research. For example, in 2023, 41 US states sued Meta on similar issues, and the judge ruled that Meta's lawyers had attempted to block internal research showing that its platform was harmful to teenagers. As concerns intensify, countries around the world are taking more aggressive measures. Malaysia recently announced that it will join Denmark and Australia in planning legislation to ban minors from using social media, indicating that regulators' trust in tech giants is plummeting.
