Zuckerberg Testifies in Social Media Addiction Trial

Meta CEO Mark Zuckerberg was clearly getting testy.

"That's not what I'm saying at all," said the tech billionaire. "I think you're misunderstanding what I'm saying," Zuckerberg responded. "You're mischaracterizing what I'm saying," he shot back.

The executive was testifying on Wednesday before a jury in Los Angeles in a marquee social media trial accusing Meta of deliberately designing features of Instagram to addict children, and the legal team for the family suing was intent on showing that Zuckerberg's fingerprints were all over the company's big decisions.

Mark Lanier, a Texas trial lawyer and pastor with a folksy courtroom demeanor, directed Zuckerberg's attention to a 2020 internal Meta document showing that 11-year-olds were four times as likely to keep coming back to its apps, compared to older users. Instagram and Facebook require users to be 13 to sign up.

"People who join Facebook at 11 years old? Lanier asked Zuckerberg. "I thought y'all didn't have any of those?"

Zuckerberg did admit that many users lie about their age to get on Instagram and Facebook. Enforcing age limit rules, he said, can be "very difficult."

Lanier then argued that not only did Instagram know there were users under 13, but the company aggressively sought to recruit them to the platform.

One Meta document from 2015 showed how an estimated 30% of 10- to 12-year-olds in the U.S. were using Instagram. The company had a goal to increase the time 10-year-olds spend on Instagram, another document showed.

"I don't remember the context of this email from more than ten years ago," Zuckerberg said. "I think the way we should build things is to build useful services for people to connect with their family and friends and learn about the world."

One 2018 internal Meta document stated "If we wanna win big with teens, we must bring them in as tweens," Lanier pointed out, saying that contradicted Meta's stated policies.

The legal team representing the plaintiff, a 20-year-old California woman known as "Kaley," attempted to demonstrate that the top-down goal of Meta has always been to encourage users to get on their platforms as young as possible, and once there, to figure out ways to keep them around. Often features like "beauty filters," made the app more alluring, Lanier argued.

When the company hired experts who affirmed that such appearance-enhancing filters contributed to body-image issues among young girls, Zuckerberg would not dispense with the filters, calling getting rid of them "paternalistic."

Under questioning in court, the billionaire Facebook founder responded: "What we allowed was letting people use those filters if they wanted but deciding not to recommend them to people," he said. "So that was the balance we came to to let people express themselves the way they want."

Kaley, who's also identified as KGM in court documents, often used these filters, which her lawsuit says contributed to body dysmorphia and other mental health issues.

Had Zuckerberg looked at Kaley's Instagram posts before the trial, Lanier asked? His staff had shown him some, he responded.

That's when Lanier, who is known for orchestrating spectacles at trial, had six lawyers unspool a 35-foot-wide collage of hundreds of selfies that Kaley posted to Instagram.

Lanier implored Zuckerberg to dwell on the posts. Was her account ever looked into for this much use as a child? The Meta chief executive did not say, as Kaley herself peered on from the court gallery.

When it was time for Meta's lawyer, Paul Schmidt, to ask Zuckerberg questions, he lobbed them softer and more gently. That, in turn, made Zuckerberg ease up a bit.

Zuckerberg said there's a misconception that the more attention the company captures, and the more time people spend on its apps, the better it is for Meta's bottom line, regardless of harms they may encounter.

"But if people feel like they're not having a good experience, why would they keep using the product?" Zuckerberg said.

Keeping users safe, especially teen users, has always been a priority, Zuckerberg said.

"Questions about well-being I consider part of this for sure," he said. "If you build a community and people don't feel safe, that's not sustainable and eventually people go and join another community."

The appearance of Zuckerberg, the star witness of the trial, came in the second week of what's expected to be a six-week proceeding. Other tech executives, social media specialists, addiction experts and others have also testified.

Kaley, the plaintiff, is expected to deliver the most emotional testimony later in the trial.

Her lawsuit claims she began using social media young, YouTube at age 6, then Instagram at 9. She was also a frequent user of TikTok and Snap. After becoming hooked on the platforms, she said her body image issues, depression and suicidal thoughts worsened. The suit points to features like beauty filters, infinite scroll and auto-play as being tantamount to a "digital casino." Evidence of the harms of these features were concealed from the public, the lawsuit says.

In response, Meta and Google, which owns YouTube, have said the accusations over-simplify the complexity of adolescent mental health issues. The companies argue social media use does not directly cause young people to be mentally unwell, so they should not be held legally liable for a user's mental health struggles.

The family's legal team called expert witnesses who described multiple studies linking regular social media use with worsening depression, anxiety and body image issues, yet attorneys for Meta and Google have said there is no scientific evidence showing social media is the sole cause of mental anguish.

The jury will determine to what degree social media platforms should be held legally culpable for plaintiff Kaley's struggles. The trial is a bellwether case tied to 1,600 similar suits filed by families and school districts. How the jury decides is expected to influence settlement talks in all those pending cases.

While debates about social media addiction have raged for decades, it has taken until now for a major trial on the issue to unfold largely due to a federal legal shield that has protected Silicon Valley. A law known as Section 230 of the 1996 Communications Decency Act has allowed tech companies to fend off lawsuits over what users post to their sites. Social media firms have also won legal battles, including a key Supreme Court case, that have found how companies curate content on platforms is a type of protected free speech.

Despite these legal hurdles, the plaintiff's lawyers in the Los Angeles case found a way to legally attack tech giants: by treating social media apps as unsafe products, viewing Instagram, YouTube and other services as defective under product liability law. The argument is that tech companies deliberately designed social media sites as harmful and dismissed internal warnings that the services could be problematic for teenagers.

The jury will ultimately have to assess Zuckerberg's credibility, which was under scrutiny on Wednesday.

Lanier, Kaley's lawyer, brought up an internal document showing how Meta communications staffers have pushed Zuckerberg to portray himself as more "human" and "relatable," and "empathetic, and less "fake," and "corporate," and "cheesy."

When questioned about his performance in various other public settings, whether in courtrooms or before Congress, Zuckerberg showed some humility.

He said: "I think I'm actually well-known to be very bad at this," which drew some laughter from the courtroom.
