The Segmentation Paradox: When Marketing’s Core Logic Becomes Moral Gatekeeping

This article challenges a foundational assumption in marketing theory: that segmentation, targeting, and positioning are neutral analytical tools. The authors argue that when firms deny access to lawful customers, they demonstrably have the capacity to serve; the decision is not a matter of resource allocation but rather a moral judgment about consumer legitimacy, concealed within the operational language of standard marketing practice. The article introduces the concept of moral gatekeeping, defined as the organizational process through which segmentation systems convert social and reputational judgments about stigmatized individuals into technical classifications, effectively transforming exclusion into a routine managerial decision. The authors identify two distinct pathways through which this process operates. The first is selective underservicing, in which organizations claim an inability to serve a consumer group adequately despite demonstrably having the capability to do so. The second is explicit refusal, whereby organizations openly decline to serve groups whose identity or occupation conflicts with institutional reputational norms. Two empirical illustrations anchor the argument. The hospitality sector's treatment of disabled consumers exemplifies selective underservicing: hotels routinely demonstrate awareness of the specific needs of wheelchair users, blind guests, and deaf guests, yet systematically fail to translate that knowledge into adequate service provision. The exclusion of webcam workers from Colombian banking services exemplifies explicit refusal: financial institutions deny access to a legally recognized occupational group on reputational grounds, pushing workers into informal economic channels where exploitation and wage theft are substantially more likely. The authors contend that the constraint in both cases is not organizational capability but organizational willingness to apply segmentation logic equitably. They advance a policy agenda calling for documented justification requirements when organizations deny service in sectors functioning as social infrastructure, regulatory standards distinguishing discretionary commercial decisions from exclusions that undermine economic citizenship, genuine co-design authority for excluded consumers, and public accountability mechanisms when private segmentation practices effectively override legislative intent. The article concludes that marketing scholarship must confront the paradox at the heart of the discipline: segmentation is celebrated as foundational when it enables profit, yet inclusion remains treated as optional when consumer difference challenges organizational comfort. Until this paradox is addressed directly, appeals for market inclusivity will remain rhetorical rather than substantive.
