Social media is a complex environment that presents both opportunities and threats for adolescents, with self-expression and emotional support on the one hand and body-shaming, cyberbullying and addictive behaviors on the other. This complexity underscores the challenge to regulating teen social media use, but it also points to another avenue for protecting young people online: how social media platforms are designed.
The growing debate around teen social media use has intensified, with recent bipartisan policy efforts in the U.S., such as the Kids Online Safety Act, seeking to protect young people from digital harms. These efforts reflect legitimate concerns. However, broad restrictions on social media could also limit benefits for teens, throwing the baby out with the bath water.
I am a researcher who studies online safety and digital well-being. My recent work with colleagues in computer scientist Pamela Wisniewski’s Socio-Technical Interaction Research Lab underscores a critical point: social media is neither inherently harmful nor entirely beneficial. It is a tool shaped by its design, how teens use it, and the context of their experiences.
In other words, social media’s impact is shaped by its affordances – how platforms are designed and what they enable users to do or constrain them from doing. Some features foster connection while others amplify harms.
As society moves toward practical solutions for online safety, it is important to use evidence-based research on how these features shape teens’ social media experiences and how they could be redesigned to be age appropriate for young people. It’s also important to incorporate teens’ perspectives to pinpoint what policies and design choices should be made to protect young people using social media.
My colleagues and I analyzed over 2,000 posts from teens ages 15-17 on an online peer-support platform. Teens openly discussed their experiences with popular social media platforms such as Instagram, YouTube, Snapchat and TikTok. Their voices highlight a potential path forward: focusing on safety by design – an approach that improves platform features to amplify benefits and mitigate harms. This approach respects young people’s agency while prioritizing their digital well-being.
What teens say about social media
While social media’s worst outcomes such as cyberbullying or mental health crises are often in the spotlight, our research shows that teens’ experiences are far more nuanced. Instead, platforms enable diverse outcomes depending on their features and design.
Teens commonly described negative experiences involving social drama, cyberbullying and privacy violations. For example, Instagram was a focal point for body-shaming and self-esteem issues, driven by its emphasis on curated visual content. Facebook triggered complaints about privacy violations, such as parents sharing private information without teens’ consent. Snapchat, meanwhile, exposed teens…
