In a pivotal moment for the tech industry, Instagram’s CEO, Adam Mosseri, has firmly dismissed claims that social media platforms are ‘clinically addictive’. This assertion comes amidst a high-profile trial in Los Angeles, where Meta and Google are facing allegations that their design features, such as infinite scrolling and autoplay videos, contribute to addictive behaviours, particularly among young users. The outcome of this trial could set significant precedents regarding the responsibilities of tech companies in safeguarding user well-being.
The Legal Landscape
The trial, which has drawn comparisons to the landmark litigation against tobacco firms in the 1990s, revolves around the assertion that the mechanisms of social media are systematically conditioning users—especially children—towards addictive behaviours. During closing arguments, attorney Mark Lanier described the case as “easy as ABC”, suggesting that the evidence against the defendants was compelling. He accused Meta and Google of “addicting the brains of children”, a claim that both companies vehemently refute.
Mosseri and his colleagues argue that their primary focus is developing a “safer, healthier experience” for users. However, the trial has revealed internal communications that suggest a different narrative. Some Meta employees have expressed concerns over rising “reward tolerance” among users, with one email referring to Instagram as a drug and another suggesting that social media companies are akin to “pushers”.
The Mechanics of Engagement
At the heart of the debate are the features designed to enhance user engagement. Infinite scrolling, for instance, offers an unending stream of content that can keep users glued to their screens. Arturo Béjar, a former child safety engineer at Meta, explained that this feature creates a perpetual cycle of anticipation and reward, driving users to continually seek out new content. He articulated the psychological impact of this design choice: “You are constantly chasing… there is the promise of something else that catches your attention right after.”

Sonia Livingstone, a social psychology professor at the London School of Economics, noted that the rapid-fire nature of social media feeds encourages impulsive behaviour. Users make split-second decisions to scroll, watch, and engage, often driven by the thought that the next post could provide satisfaction.
Autoplay and Notifications: The Hidden Traps
Autoplay functionality is another contentious feature. Initially met with user disdain for being disruptive, this design choice has proven successful for increasing viewer engagement, albeit at the expense of user satisfaction. Béjar pointed out that while advertisers benefit from higher viewership, many users find the experience frustrating.
Moreover, notifications and the quest for likes serve to amplify user engagement further. Mark Griffith, a behavioural addiction expert, noted that the rush of receiving likes triggers the release of dopamine, creating a cycle of reward that can lead to habitual usage. Yet, he cautioned against equating this to traditional addiction. While some individuals may exhibit addictive-like behaviours, Griffith emphasised that most users fall into the realm of “habitual use”, where social media affects daily life but does not dominate it.
The Verdict and Its Implications
As jurors in the trial began deliberations, the tech community is abuzz with speculation about the potential outcomes. The verdict could significantly influence how social media platforms are designed and operated in the future, particularly regarding user protection and ethical responsibilities.

Why it Matters
The implications of this trial extend far beyond the courtroom. If the jurors decide in favour of the plaintiffs, it could usher in a new era of regulation for technology companies, compelling them to rethink their design strategies to prioritise user health over engagement metrics. This moment underscores the growing scrutiny of social media platforms and their impact on society, challenging the industry to balance profitability with ethical considerations in a rapidly evolving digital landscape.
