As the debate surrounding social media’s impact on mental health escalates, Instagram’s chief executive, Adam Mosseri, has made a bold assertion: social media platforms are not ‘clinically addictive’. This statement comes in the wake of a high-profile trial involving Meta and Google, where the consequences of features like infinite scrolling and autoplay videos are under scrutiny. With closing arguments concluded, the case could have far-reaching implications for how tech companies are held accountable for their design choices.
The Trial’s Key Arguments
The courtroom drama unfolded in Los Angeles over six weeks, drawing parallels to landmark cases against tobacco firms in the 1990s. Lawyer Mark Lanier, representing the plaintiffs, argued that Meta and Google have contributed to the addiction of young users, claiming they “addicting the brains of children.” In stark contrast, Mosseri has insisted that providing a “safer, healthier experience” for users is at the core of Instagram’s mission.
Features such as autoplay videos and endless scrolling were central to the prosecution’s case, raising questions about whether these elements are merely tools for user engagement or if they are, in fact, mechanisms of addiction. As the jury begins deliberations, the outcome could redefine the responsibilities of tech giants in shaping user experiences.
Unpacking Infinite Scroll
Once upon a time, users could reach the end of a social media feed. Today, with infinite scrolling, the experience is designed to keep users engaged indefinitely. Arturo Béjar, a former child safety whistleblower at Meta, describes the mechanism as an endless cycle of dopamine hits, constantly enticing users with the promise of more engaging content.
Internal communications revealed during the trial highlighted growing concerns among Meta employees about rising “reward tolerance” among users. One email exchange likened Instagram to a drug, with a colleague quipping that all social media platforms function as “pushers.” This suggests an awareness within the company of the potential psychological impact of their design choices.
Sonia Livingstone, a social psychologist at the London School of Economics, noted how quickly users scroll through their feeds, making rapid decisions on what to engage with. The anticipation of discovering something rewarding keeps users hooked, compelling them to swipe continuously, often without realising the time spent online.
The Role of Autoplay Videos
Autoplay videos have become ubiquitous across platforms like Netflix and YouTube, but Béjar recalls a time when user feedback indicated a dislike for the feature. Although it was disruptive, the autoplay function resulted in increased viewership—a win for advertisers, despite user discontent.
Béjar explains that autoplay plays on human curiosity, compelling users to watch enough to grasp the context. Lanier likened this to the experience of free tortilla chips at a restaurant; the more you consume, the harder it is to stop.
Notifications and the Fear of Missing Out
The architecture of social media is designed to foster engagement through notifications and likes, creating a competitive atmosphere that can be particularly potent among younger users. Mark Griffith, a behavioural addiction expert, notes that the thrill of receiving likes generates a pleasurable reaction akin to a chemical reward, driven by dopamine production.

While Griffith acknowledges that social media can be addictive for some, he differentiates this from substance addictions like nicotine or cocaine. He suggests that most users experience a “moreish quality” rather than a clinical addiction. Social media use predominantly falls into two categories: habitual use, which may disrupt productivity and relationships, and problematic use, which can have more severe consequences.
In his testimony, Mosseri reiterated that social media is not “clinically addictive”, drawing a parallel to the enjoyment derived from binge-watching a television series rather than a pathological dependency.
The Jury’s Decision and Its Implications
As jurors in the case against Meta and Google begin their deliberations, their verdict will be closely monitored. It holds the potential to reshape not only the responsibilities of tech companies but also the legislative landscape surrounding digital platform design. A ruling against the tech giants could herald a new era of accountability, prompting a reevaluation of how platforms engage users and the ethical implications of their design choices.
Why it Matters
The outcome of this trial could alter the trajectory of social media regulation significantly. As society grapples with the consequences of digital engagement, the implications for user safety and mental health cannot be understated. If the court finds that features designed to maximise engagement contribute to addiction, it may compel tech companies to rethink their strategies. This could lead to a more balanced approach to user interaction, prioritising well-being over engagement metrics, ultimately reshaping the digital landscape for future generations.
