Gen Z Is Pioneering a New Understanding of Truth
The polar bear the video has millions of views. Set to haunting piano music that has become omnipresent on TikTok, it shows a solitary bear swimming between increasingly distant ice floes. The comments section is full of teenage heartbreak, rage, and helplessness.
Next to my laptop screen is the latest report from the Intergovernmental Panel on Climate Change (IPCC). Same subject, different universe. The measured language of climate science stands in stark contrast to the raw emotions evoked by this TikTok. Both contain some truth, but also fundamentally different frequencies of human understanding.
Generation Z, the first generation to spend their formative years in the smartphone era, has developed a fundamentally different relationship with the truth.
Starting in 2010, researchers in several countries began to document a sharp increase in anxiety, depression, loneliness, self-harm, and social withdrawal among adolescents. Data from large-scale surveys conducted in the US, UK, Canada, Australia and Europe showed similar trends between 2012 and 2014. The timing matched almost exactly when smartphones, front-facing cameras and algorithm-driven content platforms became the dominant centers of teens’ social lives.
Studies using data from the Centers for Disease Control and Prevention’s long-running Youth Risk Behavior Survey, the University of Michigan’s Monitoring the Future study, and parallel international mental health datasets have found sharp increases among adolescent girls in depressive symptoms, sleep disturbances, and persistent feelings of sadness and hopelessness. Researchers also documented a decline in face-to-face social interactions as well as a dramatic increase in time spent interacting online.
But the deeper transformation was not simply psychological. It was cultural and cognitive. As social life migrated to platforms optimized for engagement, visibility, and emotional reactions, questions of truth were increasingly filtered through identity, emotion, and social validation rather than slower institutional systems of evidence, authority, and debate. Beyond changing what young people consume, social media has also changed the way they deal with reality. This shift from shared public truth to personalized, algorithmically enhanced truth is at the center of the future of truth.
“Our realities,” says Emma Lembke, “are shaped by a profit-driven attention economy that prioritizes engagement over well-being.” Lembke is director of Gen Z Advocacy at the Sustainable Media Center, a nonprofit I run that brings together an intergenerational council to protect children from the harms of social media. She has spent years organizing young people around these issues, tracking platform behavior, and building coalitions between researchers, lawyers, and youth advocates. For her, it is not an abstract threat. This is the daily life of his generation.
The danger is no longer just misinformation. Thanks to AI, it is now possible to manufacture false realities on a large scale. Deepfake videos, cloned voices and fake news are dissolving the line between what is real and what is not faster than society can adapt.
Fully AI-generated characters, with faces, voices, stories and millions of followers, are already operating on Instagram and TikTok, indistinguishable from human influencers. Generation Z did not create this problem. They inherited it. And they navigate without a map, in flows that have no obligation to tell them what is real. For Generation Z, whose understanding of the world is already filtered through algorithmic feeds, reality itself often arrives pre-organized, emotionally optimized, and computationally amplified.
Scott Galloway, a New York University professor and media critic, has been outspoken about how AI and algorithmic platforms are reshaping the truth for Generation Z. He argues that AI-powered platforms like Facebook and TikTok are not just social networks. They have become engines of influence capable of shaping what millions of young people see, believe, fear and ultimately accept as real.
At the heart of Galloway’s critique is the idea that engagement has replaced human judgment as the organizing principle of online information. Platforms are optimized not for accuracy, empathy, or discussion, but for attention and emotional response. “They’re not exploring the real world; they’re not exploring the best of us,” he said during a panel with Lembke at the Sustainable Media Center. “They explore the comments section.”
This tension between emotional experience and factual truth is particularly visible in the context of climate change. Climate activist Xiye Bastida, one of the most visible Gen Z voices in the global climate movement, has argued that social media allows young users to experience climate change through human stories and first-hand accounts, creating an emotional understanding of the crisis that feels very different from just reading scientific reports.
