The New Frontier of Liability

Social media liability is entering new territory as courts consider whether the design of digital platforms can contribute to real-world harm.

For years, concerns about children and social media largely belonged to parents, pediatricians, educators and policymakers. Increasingly, they also belong to the courts.

A growing wave of litigation against some of the world's largest technology companies is asking a consequential question: What happens when the alleged danger is not simply the content appearing on a platform, but the design of the platform itself?

Thousands of lawsuits have been brought against companies including Meta, TikTok, Snap and Google alleging that social media platforms were deliberately designed to encourage compulsive use among children and adolescents, and that those design choices contributed to serious mental-health injuries. Southern Med Law is currently involved in this litigation, representing families who believe their children's mental health was harmed by platform design.

The litigation could help define an entirely new frontier of product liability and mass tort law.

From Harmful Content to Harmful Design

The distinction matters — and it's the reason this litigation has been able to move forward at all.

For years, Section 230 of the Communications Decency Act shielded technology companies from liability for content posted by third parties on their platforms. That immunity made claims based on what appeared on a platform extremely difficult to bring.

Plaintiffs in the current wave of cases are taking a different approach. Rather than focusing on individual pieces of content, they are focusing on the architecture of the products themselves: recommendation algorithms, infinite scrolling, autoplay, push notifications and other features allegedly engineered to maximize engagement among young, still-developing users. Courts in a number of these cases have allowed claims to proceed on the theory that a platform's design — as opposed to the content it hosts — falls outside Section 230's protection.

That reframing changes the legal question entirely.

Instead of asking only whether a technology company should be responsible for content created by someone else, courts are increasingly being asked to consider whether companies can be held responsible for the foreseeable consequences of their own product-design decisions.

It is a question with implications far beyond social media.

The Difficult Question of Medical Causation

For plaintiffs, establishing that a platform was designed to maximize engagement is only part of the equation.

They must also confront a considerably more complicated question: Did the alleged exposure cause or contribute to an individual's injury?

Mental health rarely presents a simple causal pathway. Depression, anxiety, eating disorders, self-harm and other conditions can involve biological, environmental, developmental and social factors.

That makes expert testimony and careful examination of the medical evidence particularly important.

Courts and juries may ultimately have to distinguish between ordinary social media use, problematic use and clinically significant impairment while determining whether a particular platform substantially contributed to an individual plaintiff's condition.

Those questions should sound familiar to attorneys who practice in complex medical and product-liability litigation. The technology may be new. The challenge of proving causation is not.

A Rapidly Developing Mass Tort Landscape

The scale — and pace — of this litigation is another reason it deserves attention.

Thousands of claims are now consolidated in a federal multidistrict litigation before the U.S. District Court for the Northern District of California, alongside a coordinated proceeding in California state court and additional cases filed in jurisdictions around the country. Bellwether trials are beginning to test plaintiffs' theories before juries, and early rulings on Section 230 and product-design claims are already shaping how these cases will be litigated going forward.

Those early cases can provide important information about how jurors respond to evidence involving product design, corporate knowledge, medical causation and damages.

There are echoes of previous mass tort litigation involving pharmaceuticals, medical devices and other consumer products: allegations of widespread exposure, disputed scientific evidence, internal corporate knowledge and potentially enormous aggregate liability.

Social media litigation will develop its own body of law, and significant legal questions remain unresolved. But its trajectory demonstrates how traditional principles of product liability are being applied to products that are increasingly digital rather than physical.

When the Product Is an Experience

Perhaps the most consequential aspect of these cases is what they suggest about the evolving definition of a "product."

For much of product-liability law, the object at issue was tangible: a medication, medical device, automobile or piece of machinery.

A social media platform presents something different. The product is continuously changing. Algorithms respond to individual behavior. Recommendations are personalized. The user's interaction with the product can influence what the product presents next.

That creates extraordinarily complex questions about exposure and causation.

If courts increasingly recognize design features and algorithmic systems as potentially actionable product characteristics, the consequences could extend well beyond social media.

The central question may no longer be simply what did the product contain?

Increasingly, it may be: what was the product designed to make its user do?
