In a significant court case that has captivated both the tech industry and public discourse, Instagram’s chief executive Adam Mosseri has taken a firm stance against claims that social media platforms are ‘clinically addictive’. This assertion comes amidst ongoing legal scrutiny of Meta and Google, where features like infinite scrolling and autoplay functionality are under fire for allegedly fostering addictive behaviours, particularly among young users. As the trial in Los Angeles draws to a close, the implications for the tech sector could be profound.
The Trial and Its Implications
The case being heard in Los Angeles has drawn parallels to the landmark litigation against tobacco companies in the 1990s. Prosecutor Mark Lanier stated that the defendants were guilty of “addicting the brains of children,” a claim that has been robustly denied by the tech giants. Meta, for its part, maintains that its goal is to create a “safer, healthier experience” for users, particularly the younger demographic.
As this six-week trial comes to a head, the courtroom discussions surrounding the design elements of social media platforms are drawing increased attention. Critics argue that features designed to enhance user experience may, in fact, be responsible for fostering compulsive behaviours rather than simple engagement.
The Mechanics Behind Infinite Scrolling
Once upon a time, social media feeds had a definitive endpoint. Now, the concept of infinite scrolling means that users can endlessly consume content, leading to a cycle of perpetual engagement. Arturo Béjar, a former employee at Meta focused on child online safety, highlighted that this feature is engineered to provide “an infinite supply” of stimuli that generates dopamine responses in users.

Internal communications revealed during the trial suggest that there are concerns within Meta about rising “reward tolerance” among users. One email exchange from 2020 noted Instagram was akin to a drug. Béjar articulated the challenge of this design: users are continually “chasing” the next piece of engaging content, often leading to hours spent scrolling without a clear endpoint.
Sonia Livingstone, a professor of social psychology at the London School of Economics, added that the rapid-fire decision-making process as users swipe through feeds fuels a cycle of anticipation. The thrill of potentially discovering something rewarding keeps users locked into their digital worlds, blurring the lines between enjoyment and compulsion.
Autoplay: Convenience or Compulsion?
The rise of autoplay functionality has transformed content consumption across platforms like Netflix, YouTube, and Instagram. Béjar noted that although many consumers initially disliked autoplay for its disruptive nature, the feature ultimately increased viewing times and satisfied advertisers. Autoplay effectively taps into an innate human tendency to want to understand and engage with what is presented, thereby keeping users glued to their screens.
Lanier likened the experience of engaging with endless scrolling and autoplay to enjoying free tortilla chips at a restaurant—delicious but potentially overwhelming. This analogy underscores the tension between user satisfaction and the potential for overconsumption.
The Role of Notifications and the ‘FOMO’ Factor
Notifications, likes, and other interactive features are integral to keeping users engaged, particularly among younger audiences. According to Mark Griffith, a behavioural addiction expert at Nottingham Trent University, the competition for likes and engagement generates a rush of dopamine, which can lead to a cycle of habitual use.

While Griffith acknowledged that some individuals may develop a genuine addiction to social media, he emphasised that this is not comparable to substance addictions like nicotine or cocaine. Instead, he suggested that social media’s allure often stems from its “moreish quality,” which can lead to habitual use that affects productivity and relationships without necessarily resulting in severe consequences.
In a testament to the ongoing debate, Adam Mosseri defended the platforms, asserting that social media can be likened to binge-watching a popular television series—engaging but not inherently addictive. As jurors in the trial prepare to deliver their verdict, the outcome could redefine the responsibilities of tech companies regarding platform design.
Why it Matters
The implications of this trial extend far beyond the courtroom. As society grapples with the influence of technology on mental health, the findings from this case may shape future regulations and corporate responsibilities in the tech industry. The way in which platforms design user interactions could be scrutinised more rigorously, potentially leading to a reshaping of practices that prioritise user well-being over engagement metrics. This trial represents a pivotal moment in the ongoing conversation about the ethical obligations of technology companies, particularly in safeguarding vulnerable populations such as children and adolescents.
