The act of purchase, stripped of its commercial dressing, is a social gesture. It signals belonging, projects aspiration and, in its more anxious iterations, wards off the threat of misclassification. That a £120 trainer and an £80 one are functionally indistinguishable is not, as economists once implied, evidence of irrationality. It is evidence that the buyer is solving a rather more complex problem than the one printed on the price tag.
This complexity has deep roots. Thorstein Veblen identified it in 1899, observing that the leisure class consumed not for sustenance but for standing. Pierre Bourdieu refined the argument eight decades later, demonstrating that taste—in clothes, food, furniture, language—functions as a form of social currency, accumulated and spent within the hierarchies of class. Neither man was describing extravagance. They were describing a universal mechanism. Consumption, in their accounts, is the primary vocabulary through which modern societies speak about themselves.
The branded marketplace is merely the latest dialect.
The burden of classification
Every purchase carries what sociologists call a classificatory risk: the danger of being placed, by others, in the wrong category. A professional who arrives at a client meeting carrying the wrong laptop, wearing an unfamiliar label or driving an incongruous car does not merely risk aesthetic misjudgement. They risk being read as belonging to a different tribe—less successful, less cultured, less aligned with the norms of the room. Brands exist, in part, to manage this anxiety. They are social insurance policies, priced accordingly.
This is why information asymmetry alone cannot explain brand premiums. In categories such as financial services or pharmaceuticals, where quality is genuinely opaque, the argument for a trusted name as a substitute for due diligence is persuasive. But it struggles to account for the premium on a cotton T-shirt or a bottle of mineral water, where the functional case is negligible. Here the sociological explanation is more honest: the buyer is not purchasing a product but a position.
Erving Goffman’s dramaturgical framework, developed in the 1950s, anticipated the digital age with unsettling precision. Social life, he argued, is performance. Individuals are perpetually managing the impressions they make on others, deploying props, costumes and scripts to project a coherent self. Brands are among the most legible of these props. A logo on a chest, a handset placed face-up on a café table, a carrier bag retained long after its contents have been consumed—each is a line of dialogue in an ongoing performance whose audience is everyone in the vicinity.
Social media has not invented this theatre. It has simply enlarged the auditorium.
The self as market
Contemporary consumer culture has introduced a further complication: the commodification of identity itself. Brands no longer merely accompany the self; they increasingly constitute it. Companies invest heavily in positioning themselves not as providers of goods but as custodians of values—environmental responsibility, creative rebellion, radical inclusivity. The consumer who adopts such a brand does not merely buy a product. They acquire a narrative about who they are and, crucially, who they are not.
This dynamic has been studied extensively in the context of what researchers call self-congruity theory: the proposition that consumers prefer brands whose perceived personalities match their own self-concept, whether actual or aspirational. The data are robust across cultures and categories. People do not simply choose products that perform well. They choose products that perform their identity well.
The implications are uncomfortable for orthodox marketing. If what is being sold is not a product but a self-image, then quality—however necessary as a baseline—is not the primary competitive variable. Coherence is. The brand must sustain a legible, consistent identity across every point of contact: packaging, pricing, customer service, public conduct, the tone of an automated reply. Any inconsistency introduces noise into the signal the consumer is trying to send about themselves. That noise erodes not merely satisfaction but something closer to self-esteem.
When the signal misfires
The fragility of this arrangement becomes visible under pressure. The 2008 financial crisis reordered brand hierarchies with clinical speed. Institutions that had cultivated images of prestige and sophistication found those images suddenly liabilities. To be associated with excess became, briefly, a social penalty rather than a social reward. Customers did not simply migrate for better rates; they migrated to repair their self-presentation. The brands that survived with equity intact were those perceived as prudent, reliable and—a revealing word—honest.
More recently, the proliferation of purpose-driven branding has produced its own contradictions. When a company proclaims solidarity with a social cause while its supply chain, labour practices or lobbying activity tell a different story, the dissonance is experienced by loyal consumers as a personal betrayal. They have, after all, staked a fragment of their identity on the brand’s integrity. The reputational damage that follows is therefore disproportionate to the original offence—not because consumers are vindictive, but because the compact that was broken was never merely commercial.
This is the structural reality that marketing departments frequently misread. Brand loyalty is not affection for a product. It is investment in a shared fiction—a fiction that the consumer and the company have agreed, tacitly, to maintain. The moment the company withdraws from that agreement, the consumer is not merely disappointed. They are exposed.
The limits of desire
None of this should be mistaken for cynicism about consumption. People are not dupes. They are agents navigating a social world of genuine complexity, using the tools available to them. Brands happen to be among the most efficient of those tools: dense with information, portable across contexts and legible to strangers without explanation. That their use also enriches shareholders is a feature of the system, not a revelation about the gullibility of buyers.
What it does reveal is that the language of rational choice, still dominant in boardrooms and business schools, is an impoverished guide to understanding why people buy what they buy. The consumer standing before a shelf is not running a utility calculation. They are asking, with varying degrees of consciousness, a rather older question: what does this choice say about me, and will the answer be believed?
The brands that prosper over time are those that take this question seriously—not by manipulating the answer, but by earning the right to be part of it. Quality earns entry. Consistency builds trust. But it is the social meaning that a brand accumulates, through conduct as much as communication, that determines whether a consumer will stake their identity on it twice.
The logo, in the end, is not a mark of ownership. It is a claim about the kind of person who chooses it. Whether that claim holds is tested not in the shop, but everywhere else.
