TikTok settles as social media giants face landmark trial over youth addiction claims

Details of the settlement with TikTok were not disclosed, and the company did not immediately respond to a request for comment.

At the core of the case is a 19-year-old identified only by the initials “KGM,” whose case could determine how thousands of other, similar lawsuits against social media companies will play out. She and two other plaintiffs have been selected for bellwether trials — essentially test cases for both sides to see how their arguments play out before a jury and what damages, if any, may be awarded, said Clay Calvert, a nonresident senior fellow of technology policy studies at the American Enterprise Institute.

Joseph VanZandt, co-lead counsel for the plaintiff, said in a statement Tuesday that TikTok remains a defendant in the other personal injury cases, and that the trial will proceed as scheduled against Meta and YouTube.

Jury selection starts this week in the Los Angeles County Superior Court. It's the first time the companies will argue their case before a jury, and the outcome could have profound effects on their businesses and how they will handle children using their platforms. The selection process is expected to take at least a few days, with 75 potential jurors questioned each day through at least Thursday. A fourth company named in the lawsuit, Snapchat parent company Snap Inc., settled the case last week for an undisclosed sum.

“This was only the first case — there are hundreds of parents and school districts in the social media addiction trials that start today, and sadly, new families every day who are speaking out and bringing Big Tech to court for its deliberately harmful products,” said Sacha Haworth, executive director of the nonprofit Tech Oversight Project.

KGM claims that her use of social media from an early age addicted her to the technology and exacerbated depression and suicidal thoughts. Importantly, the lawsuit claims that this was done through deliberate design choices made by companies that sought to make their platforms more addictive to children to boost profits. This argument, if successful, could sidestep the companies' First Amendment shield and Section 230, which protects tech companies from liability for material posted on their platforms.

“Borrowing heavily from the behavioral and neurobiological techniques used by slot machines and exploited by the cigarette industry, Defendants deliberately embedded in their products an array of design features aimed at maximizing youth engagement to drive advertising revenue,” the lawsuit says.

Executives, including Meta CEO Mark Zuckerberg, are expected to testify at the trial, which will last six to eight weeks. Experts have drawn similarities to the Big Tobacco trials that led to a 1998 settlement requiring cigarette companies to pay billions in health care costs and restrict marketing targeting minors.

“Plaintiffs are not merely the collateral damage of Defendants’ products,” the lawsuit says. “They are the direct victims of the intentional product design choices made by each Defendant. They are the intended targets of the harmful features that pushed them into self-destructive feedback loops.”

The tech companies dispute the claims that their products deliberately harm children, citing a bevy of safeguards they have added over the years and arguing that they are not liable for content posted on their sites by third parties.

“Recently, a number of lawsuits have attempted to place the blame for teen mental health struggles squarely on social media companies,” Meta said in a recent blog post. "But this oversimplifies a serious issue. Clinicians and researchers find that mental health is a deeply complex and multifaceted issue, and trends regarding teens' well-being aren't clear-cut or universal. Narrowing the challenges faced by teens to a single factor ignores the scientific research and the many stressors impacting young people today, like academic pressure, school safety, socio-economic challenges and substance abuse."

A Meta spokesperson said in a statement Monday the company strongly disagrees with the allegations outlined in the lawsuit and that it's “confident the evidence will show our longstanding commitment to supporting young people.”

José Castañeda, a Google Spokesperson, said Monday that the allegations against YouTube are “simply not true.” In a statement, he said “Providing young people with a safer, healthier experience has always been core to our work."

TikTok did not immediately respond to a request for comment Monday.

The case will be the first in a slew of cases beginning this year that seek to hold social media companies responsible for harming children's mental well-being. A federal bellwether trial beginning in June in Oakland, California, will be the first to represent school districts that have sued social media platforms over harms to children.

In addition, more than 40 state attorneys general have filed lawsuits against Meta, claiming it is harming young people and contributing to the youth mental health crisis by deliberately designing features on Instagram and Facebook that addict children to its platforms. The majority of cases filed their lawsuits in federal court, but some sued in their respective states.

TikTok also faces similar lawsuits in more than a dozen states.

In New Mexico, meanwhile, jury selection begins next week for trial on allegations that Meta and its social media platforms have failed to protect young users from sexual exploitation, following an undercover online investigation. Attorney General Raúl Torrez in late 2023 sued Meta and Zuckerberg, who was later dropped from the suit.

Prosecutors have said that New Mexico is not seeking to hold Meta accountable for its content but rather its role in pushing out that content through complex algorithms that proliferate material that can be harmful, saying they uncovered internal documents in which Meta employees estimate about 100,000 children every day are subjected to sexual harassment on the company’s platforms.

Meta has said it uses sophisticated technology, hires child safety experts, reports content to the National Center for Missing and Exploited Children, and shares information and tools with other companies and law enforcement, including state attorneys general, to help root out predators.
