The polar bear clip has racked up millions of views. Paired with a melancholic piano track that’s taken over TikTok, it captures a solitary bear paddling through widening gaps between drifting ice sheets. The comment section brims with young people expressing sorrow, fury, and a sense of powerlessness.
Next to my laptop sits the newest Intergovernmental Panel on Climate Change (IPCC) report. Same topic, entirely different world. The careful, restrained language of climate research couldn’t be further from the intense feelings stirred by that TikTok. Each holds a piece of truth, yet they operate on completely different wavelengths of human comprehension.
Gen Z, the first cohort to grow up entirely within the smartphone age, has forged an entirely new way of relating to what’s true.
Beginning around 2010, scientists in numerous countries started recording a dramatic spike in teen anxiety, depression, isolation, self-harm, and withdrawal from social settings. Broad survey findings from the United States, the United Kingdom, Canada, Australia, and Europe revealed nearly identical patterns surfacing between 2012 and 2014. The timing matched almost perfectly with the period when smartphones, selfie cameras, and algorithm-powered content platforms became the central gathering places of teenage social life.
Research drawing on data from the Centers for Disease Control and Prevention’s longstanding Youth Risk Behavior Survey, the University of Michigan’s Monitoring the Future project, and comparable international mental health records uncovered sharp rises among adolescent girls in depressive episodes, sleep disturbances, and ongoing feelings of deep sadness and despair. Scientists also noted drops in in-person socializing alongside surges in hours spent engaging online.
But the more profound change wasn’t merely psychological. It was cultural and mental. As social existence shifted onto platforms built for maximum engagement, visibility, and emotional response, questions of truth increasingly passed through the lenses of identity, feeling, and peer approval rather than through the slower institutional frameworks of evidence, expertise, and deliberation. Beyond reshaping what young people absorbed, social media also transformed how they made sense of the world. That pivot, from a commonly held public truth toward individualized and algorithmically reinforced truth, lies at the heart of where truth is headed.
“Our realities,” says Emma Lembke, “are being molded by a profit-hungry attention economy that values clicks over well-being.” Lembke leads Gen Z Advocacy at the Sustainable Media Center, a nonprofit I run that unites an intergenerational board dedicated to shielding children from social media’s harms. She has devoted years to mobilizing young people around these concerns, monitoring platform practices, and forging alliances among researchers, lawyers, and youth activists. For her, this isn’t some distant, theoretical danger. It’s the daily reality of her generation.
The threat has evolved beyond simple misinformation. With AI, it’s now feasible to fabricate false realities on a massive scale. Deepfake videos, replicated voices, and fabricated news pieces are erasing the boundary between genuine and fake more quickly than society can keep up.
Completely AI-crafted personalities, complete with faces, voices, personal histories, and millions of followers are already active across Instagram and TikTok, impossible to tell apart from real human influencers. Gen Z didn’t cause this crisis. They were handed it. And they’re making their way through it without any guide, inside feeds under no duty to distinguish fact from fiction. For Gen Z, whose worldview is already shaped by algorithmic feeds, reality itself frequently shows up pre-packaged, emotionally fine-tuned, and digitally magnified.
New York University professor and media analyst Scott Galloway has been forthright about how AI and algorithm-driven platforms are redefining truth for Gen Z. He contends that AI-fueled platforms like Facebook and TikTok aren’t merely social networks. They’ve evolved into influence machines with the power to determine what millions of young people see, believe, fear, and ultimately take as fact.
At the core of Galloway’s argument is the notion that engagement has supplanted human reasoning as the guiding force behind online information. Platforms are engineered not for accuracy, compassion, or dialogue but for capturing attention and provoking emotional responses. “They aren’t scanning the real world; they aren’t scanning what’s best about us,” he remarked during a discussion with Lembke at the Sustainable Media Center. “They’re scanning the comments section.”
That friction between lived emotional experience and verifiable truth is especially apparent when it comes to climate change. Climate campaigner Xiye Bastida, one of Gen Z’s most prominent figures in the worldwide climate movement, has maintained that social media enables younger audiences to encounter climate change through personal narratives and direct testimonies, fostering an emotional grasp of the crisis that feels entirely distinct from simply reading scientific data.
