In a landmark trial taking place in Los Angeles, the spotlight is firmly on social media giants Meta and Google as they face serious allegations concerning the potential addictive nature of their platforms. Adam Mosseri, Instagram’s chief executive, firmly rejected claims that social media is “clinically addictive.” However, this case has reignited discussions about the design features of social media that critics argue are engineered to keep users, particularly children, engaged for prolonged periods.
The Core of the Controversy
At the heart of the trial are design elements like infinite scrolling, autoplay videos, and an incessant barrage of notifications. These features, integral to user experience, are accused of fostering compulsive behaviours that mirror addiction. Mark Lanier, the attorney representing the plaintiffs, asserted that these platforms have “addicted the brains of children,” a sentiment that resonates with many concerned about the impact of digital consumption on younger audiences.
In contrast, Mosseri and his team have consistently claimed their goal is to create a “safer, healthier experience.” They maintain that while these features may enhance user engagement, they do not constitute addiction in the traditional sense. The trial has drawn parallels to historical lawsuits against the tobacco industry, highlighting the potential responsibility of tech companies for the psychological effects of their products.
Infinite Scroll: A Never-Ending Loop
Gone are the days when social media feeds were finite. The advent of infinite scrolling has transformed the way users interact with content online. Arturo Béjar, a former child safety advocate at Meta, explained that the endless scroll lures users into a cycle of constant engagement, where there is always “something more” waiting to be discovered. This design strategy is predicated on the idea of providing an unending stream of dopamine-releasing content, reinforcing user behaviour that may lead to compulsive consumption.

Internal communications revealed during the trial indicated that even Meta employees were concerned about the implications of this feature. One email exchange from 2020 likened Instagram to a drug, underscoring fears that the platform might be manipulating users’ psychological responses.
The Impact of Autoplay and Notifications
Autoplay videos, now ubiquitous across various platforms, were initially met with resistance from users, according to Béjar. While advertisers revelled in the uptick in video views, users expressed dissatisfaction with the disruptive nature of such features. Autoplay capitalises on human curiosity, compelling individuals to watch just a bit longer to fully grasp the content, which in turn increases exposure to advertising.
Alongside autoplay, notifications and the race for likes contribute to what experts term “fear of missing out” (FOMO). Mark Griffith, a behavioural addiction expert, pointed out that the competitive nature of social media engagement can trigger dopamine release, akin to addictive behaviours. While he noted that few would meet the strict criteria for clinical addiction, he acknowledged a “moreish quality” to social media that keeps users returning for more.
The Verdict’s Potential Implications
As jurors in the case against Meta and Google begin their deliberations, the outcome could have far-reaching consequences for how technology companies are held accountable for their design choices. Should the court side with the plaintiffs, it may usher in a new era of regulatory scrutiny, compelling tech giants to reassess their engagement strategies and implement changes aimed at promoting healthier user interactions.

Why it Matters
This trial is not merely about the practices of two tech behemoths; it represents a critical examination of the broader implications of social media design on public health, particularly among vulnerable populations like children. As society grapples with the balance between engaging digital experiences and the potential for addictive behaviours, the outcome could redefine the ethical responsibilities of technology companies. The verdict may set a precedent that influences how platforms operate and how they are regulated, shaping the future landscape of digital interaction.
