This week, Adam Mosseri, the CEO of Instagram, firmly rejected claims that social media platforms are “clinically addictive”. His comments come amid a high-profile legal case in the United States that has scrutinised the very design elements of these platforms—such as infinite scroll and autoplay functionalities—that some argue foster compulsive usage. As the case unfolds, the implications for Meta and Google could potentially reshape the landscape of social media responsibility and user engagement.
A Landmark Legal Case
The ongoing trial in Los Angeles, which has captured significant attention, centres on accusations that major tech companies, including Meta and Google, have engineered their platforms to encourage addictive behaviours, particularly among younger audiences. Mark Lanier, the attorney representing the plaintiffs, stated in closing arguments that the defendants have been “addicting the brains of children”, a sentiment that has sparked intense debate about the ethical implications of social media design.
In response, Mosseri maintained that Instagram’s mission has always been to create a “safer, healthier experience” for its users. He refuted the notion that these platforms are designed to create addiction, suggesting instead that they are simply offering what consumers desire.
The Mechanics of Infinite Scroll
One of the pivotal features in question is infinite scrolling, which allows users to consume content continuously without a defined endpoint. Arturo Béjar, a whistleblower and former child online safety officer at Meta, explained that this feature exploits human psychology, providing a constant stream of stimuli that can lead to compulsive behaviour. “There is always something more that will give you another dopamine hit,” he noted, highlighting the underlying mechanics that keep users engaged.

Internal communications revealed during the trial indicate that some Meta employees were concerned about the growing “reward tolerance” among users, with discussions likening Instagram to a drug. Such revelations point to an awareness within the company of the potential psychological impact of their design choices.
The Role of Autoplay Videos
Autoplay videos have become ubiquitous on platforms ranging from Netflix to Instagram, and they have been a focal point in discussions about user engagement. Béjar, who witnessed the rise of this feature at Facebook, noted that while users initially disliked it for being disruptive, the end result was a higher consumption of video content, much to the delight of advertisers.
Drawing parallels to the experience of eating free tortilla chips at a restaurant—where the enjoyment can lead to overindulgence—Lanier emphasised the compulsive nature of these features. They exploit innate human tendencies to seek out information and entertainment, but at what cost?
The Fear of Missing Out
Another key factor in user engagement is the fear of missing out (FOMO), which is amplified by notifications and social validation mechanisms such as likes. Mark Griffith, a behavioural addiction expert, highlighted that the competitive nature of social media can provide users with dopamine rewards, reinforcing their engagement with the platforms. However, he also cautioned against conflating social media use with clinical addiction.

Griffith differentiated between “habitual use,” which can adversely affect productivity and personal relationships, and “problematic use,” which has more severe consequences. Mosseri echoed this distinction, arguing that while social media can be habit-forming, it does not equate to clinical addiction in the way substances like nicotine or cocaine do.
Implications of the Verdict
As jurors in the case began deliberations, the outcome could have far-reaching consequences for how tech companies approach platform design. A ruling against Meta and Google could prompt a reassessment of their responsibilities regarding user engagement strategies and the ethical implications of their design choices.
Why it Matters
The trial against Meta and Google serves as a crucial examination of the intersection between technology, mental health, and corporate responsibility. As society grapples with the pervasive influence of social media on daily life, the findings could catalyse a broader conversation about the ethical frameworks that should govern platform design. The case not only challenges the tech giants to reconsider their business practices but also empowers users to demand a more mindful approach to online engagement.
