Is Social Media Addictive? Zuckerberg Admits Instagram Flaws

Los Angeles – Meta CEO Mark Zuckerberg testified on Wednesday, February 18, 2026, in a landmark trial concerning the potential addictive nature of Instagram and its impact on young users. The case, brought by over 1,600 plaintiffs including families and school districts, alleges that Meta knowingly designed its platforms to be harmful to the mental health of children and teenagers. While Zuckerberg maintained that Meta does not intentionally seek to make Instagram addictive, he acknowledged shortcomings in the platform’s age verification processes.

The trial centers around the experiences of K.G.M., now 20 years old, who began using Instagram at age nine. Her lawsuit, and those consolidated with it, claims that features like recommendation algorithms and infinite scrolling are deliberately engineered to foster addiction. Zuckerberg faced questioning regarding Meta’s policies surrounding users under the age of 13, a demographic officially prohibited from using Instagram.

Zuckerberg conceded that enforcing this age restriction is challenging, stating that “there are a meaningful number of people who lie about their age to use our services.” He was confronted with internal Meta documentation suggesting that Instagram had approximately four million users under 13 in 2015. When asked about the pace of improvement in age verification, Zuckerberg admitted, “The age control has not improved at the desired pace in retrospect. I always wished we had achieved it sooner,” but asserted that the system is now “on the right track.”

A key point of contention during the testimony revolved around the question of whether Meta actively aims to maximize user engagement, even if it means increasing time spent on the platform. Zuckerberg stated that Meta measures time spent on Instagram as a metric to gauge its competitiveness against platforms like TikTok, but insisted this isn’t equivalent to a deliberate effort to create addiction. “It’s different than us trying to just increase time,” he explained. “Just us trying to see how we’re stacking up in the industry.”

The legal team representing the plaintiffs, led by Mark Lanier, argued that social media companies like Meta and Google have effectively engineered addiction into the brains of children, prioritizing advertising revenue over user well-being. Lanier’s opening arguments posited that these companies intentionally designed their apps to be habit-forming, leading to significant psychological harm. Instagram’s head of product, Adam Mosseri, previously contested the claim that the app possesses addictive qualities.

Zuckerberg also addressed the controversy surrounding Instagram’s beauty filters, which allow users to alter their appearance. Meta temporarily removed these filters following concerns that they promoted unrealistic beauty standards and potentially encouraged cosmetic surgery. Zuckerberg explained that the company ultimately decided to reinstate them in the name of “free expression,” while also acknowledging a responsibility to avoid creating or recommending such filters themselves.

This trial is significant as it represents the first time a major social media CEO has been compelled to testify before a jury regarding the safety of children on their platform. Historically, Section 230 of the Communications Act of 1934 has shielded internet companies from liability for content posted by users. However, this case seeks to challenge that protection by arguing that the platforms themselves are inherently harmful due to their design. TikTok and Snap have already reached settlements with the plaintiff, K.G.M., prior to the trial’s commencement.

The outcome of this case could have far-reaching implications for the social media industry. A ruling against Meta could open the door to further lawsuits and potentially lead to stricter regulations governing the design and operation of social media platforms, particularly concerning their impact on young users. The trial raises fundamental questions about the responsibilities of tech companies to protect their users, and the balance between free expression, user engagement, and mental health.

Zuckerberg’s testimony offered a glimpse into Meta’s internal thinking on these issues, but the core question of whether Instagram is designed to be addictive, and whether Meta bears responsibility for the harm it may cause, remains for the jury to decide. The case is expected to continue for several weeks, with further testimony from experts and witnesses anticipated.
