The Like Addiction: Why We Hunt for Online Validation, Likes and Follows

What does it mean when a stranger clicking a small icon can alter how we feel about ourselves? When the first thing many of us reach for in the morning is not water or quiet thought but a glowing screen on which we count, almost involuntarily, how many people approved of something we shared while we slept, is it not worth pausing to ask what is actually happening inside us? These are not trivial questions. They point toward something deep and old in human nature, something that the architecture of modern social media has learned to exploit with remarkable precision.

The desire for social approval is not a pathology invented by smartphones. It is woven into the fabric of what we are. Evolutionary psychologists have long argued that belonging to a group, and being valued within it, was once a matter of survival. To be cast out was to be exposed. To be seen and affirmed was to be safe. The human nervous system still carries that ancient arithmetic, and it responds to social signals accordingly. What has changed is not the hunger but the marketplace in which we now try to satisfy it. We have moved from the village, where approval was slow, embodied and contextual, to a vast and instantaneous arena where validation is measured in numerical increments and refreshed by the minute.

The neurological dimension of this shift deserves careful attention. Research into dopamine, the neurotransmitter associated with anticipation and reward, suggests that variable and unpredictable rewards are far more compelling than consistent ones. A notification that sometimes brings thirty likes and sometimes brings three produces precisely the kind of intermittent reinforcement that keeps behaviour locked in place. This is the same mechanism at work in gambling. The scholar and addiction specialist Natasha Dow Schull has written extensively about how slot machines are designed to exploit this feature of human psychology, and it is not a great leap to observe that the notification systems of social platforms operate on a structurally similar principle. We pull the lever, we wait, we feel the small electric charge of being counted.

Layered on top of this neurological dynamic is the social comparison process that the psychologist Leon Festinger identified in the mid-twentieth century. Festinger proposed that human beings evaluate their own opinions and abilities by measuring them against those of others, particularly others who seem similar to themselves. Social media has turbo-charged this tendency by placing us in continuous, curated contact with the apparent lives of hundreds or thousands of people simultaneously. We are not comparing ourselves to our neighbours in any realistic sense; we are comparing ourselves to the best-lit, best-timed, most carefully edited moments from the lives of people who are, like us, performing for an audience.

This is where the curated self becomes so interesting and so troubling. The image we post is not us in any full or honest sense. It is a selection, a construction, a bid for approval dressed as spontaneity. We know this when we are the ones posting. We feel the small calculations involved: which angle, which filter, which caption signals the right combination of confidence and vulnerability. And yet, when we scroll and encounter the constructions of others, we tend to receive them as authentic. We forget that everyone else is also editing. The result is a collective illusion in which everyone appears to be thriving except the person holding the phone.

The fragility that follows from outsourcing our sense of worth to strangers is not difficult to trace. When the metric of our value can shift with a single post, when one image gathers warmth and the next passes unnoticed, the self that was built on those numbers becomes unstable. Psychologists distinguish between contingent self-esteem, which rises and falls depending on external outcomes, and a more stable, internal sense of worth that is less responsive to the daily weather of opinion. The research suggests, with considerable consistency, that contingent self-esteem is associated with higher rates of anxiety, depression and what might be called performative exhaustion. We become tired of tending the performance, and yet we cannot seem to stop.

It is worth asking what the philosophers of the good life would make of all this. The Stoic tradition, in particular, drew a firm line between what lies within our control and what does not. The judgement of others falls clearly on the outside of that line. Epictetus, a former slave who became one of the most searching moral teachers of the ancient world, argued repeatedly that a person who allows external opinion to determine inner peace has, in effect, handed sovereignty over the self to strangers. The digital equivalent of that transaction is enacted millions of times each day. We hand sovereignty to people we have never met, and we feel the consequences in our mood, our confidence and our sense of identity.

This is not, of course, an argument for indifference to community or for a cold withdrawal from shared life. Human beings need genuine connection, and there is nothing wrong with wanting to communicate, to share, to be known. The question is whether the thin, quantified feedback of a like or a follow constitutes genuine connection at all, or whether it is a simulacrum that satisfies just enough to prevent us from seeking the real thing.

Building a steadier sense of value from within is neither easy nor quick, but it is not mysterious. It involves practising what the psychologist Kristin Neff has called self-compassion: meeting oneself with the same patience and understanding one might offer a good friend. It involves engaging in activities whose reward is intrinsic rather than performed: reading, making, thinking, walking, listening. It involves asking, with some regularity, what we actually believe and value when no one is watching.

Perhaps the most honest question we can close with is this: if the screen went dark tomorrow and took all its numbers with it, what would remain of the self we have been building? And would that self be someone we actually recognise, or someone we have only ever seen from the outside?
