Who’s really choosing the playlist of your thoughts? You, or the algorithm remixing your emotions in real time?
Eight years since the release of Katy Perry’s pop hit Chained to the Rhythm, the digital world we inhabit feels even more defined by the idea of living our lives through a lens.
What was once regarded a catchy social commentary has matured into a near-prophecy; our feeds scrolling endlessly before us, every click and swipe nudging us deeper into a ‘curated’ reality. Below the surface of visually appealing interfaces and seamless interactions lies a meticulously crafted UX, engineered not only to engage but also to influence: subtly shaping our emotions, behaviours, and, most discreetly, our sense of identity.
Recent research published in the National Library of Medicine takes this conversation beyond metaphor, grounding it in neuroscience. A 2025 study, “Social Media Algorithms and Teen Addiction: Neurophysiological Impact and Ethical Considerations” maps how algorithmic design interacts with the brain’s reward pathways.
The findings indicate that personalised feeds, push notifications and infinite scroll act as behavioural triggers that activate dopamine-driven feedback loops, making disengagement a considerable challenge for adolescents, whose prefrontal cortex (the seat of impulse control and decision-making) is still in the development stages. The researchers conclude that these effects amongst teens can be magnified, that lead to compulsive use patterns that mirror substance addiction.
If this sounds abstract, the numbers make it uncomfortably real. Recent data from England paints a stark picture: mental health conditions are rising sharply among young people.
According to the House of Commons Library, between 2017 and 2023, the prevalence of probable mental disorders among children aged 8–16 rose from 12% to 20%, representing hundreds of thousands more young people in need of support. Among 16–24 year-olds, rates climbed from 18.9 % to 25.8 % in the same period. Emergency referrals for children’s anxiety have more than doubled, from roughly 99,000 in 2019–20 to over 204,000 in 2023–24. Furthermore, hospital admissions for mental health issues have surged by 65 % over the past decade, with eating disorders particularly on the rise among girls aged 11–15.
These escalating figures highlight the urgent need for intervention in the digital spaces where young people spend significant time. While algorithms and UX design have contributed to these challenges, they also hold the potential to mitigate them through intentional, ethical redesigns that prioritize well-being over unchecked engagement.
Design to the Rescue?

Recognizing that design is inherently influential, every interaction, be it a swipe, notification, or tap—leaves a lasting imprint. The critical question to ask is: what impact are we embedding in the minds of the most vulnerable users?
Cognitive Imprints
The mental traces formed through interactions shape how young users perceive future experiences. For instance, a social media feed that amplifies outrage does more than deliver content; it subtly moulds a worldview, framing how users interpret the world around them.
Emotional Residue
The emotions evoked by design choices linger long after an app is closed. A single comment, a reset streak counter, or the rush of a ‘like’ can influence an adolescent’s emotional state for hours or even days, leaving a lasting emotional footprint.
Behavioural Conditioning
Seemingly innocuous UX patterns can foster long-term habits. For teenagers, still developing impulse control, these patterns can become ingrained behaviours, such as scrolling to cope with stress or compulsively checking notifications during moments of idleness. This can have notable impacts on academic performance, relationships, and sleep quality.
As mental health data reveals rising trends in anxiety, depression, and compulsive behaviours among youth, UX must serve as a protective mechanism, not merely a driver of engagement. This requires designing for disengagement as much as for retention, creating systems that empower user autonomy, preserve mental clarity, and promote emotional well-being over relentless interaction. While algorithms will continue to optimize for attention, our responsibility is to ensure that user well-being is not the price paid for engagement.
In the end, the question isn’t whether we can break the chain; it’s whether we’ll design a future where users hold the key… or let the algorithm keep it hidden.
