A perennial issue in transformative consumer research and public policy is the plight of low‐literate vulnerable consumers. Low‐literate consumers have been observed misinterpreting labels, misusing products and purchasing the wrong item, which leads to devastating outcomes as they continue to make poor decisions out of ignorance. Based on a thorough review of past studies on consumer literacy and vulnerability, we explore how stigma and attribution operate as underlying mechanisms for influencing how low‐literate consumers behave in the marketplace. This paper problematises blanket statements that all low‐literate consumers are vulnerable and addresses the possibility that universal policy actions may inadvertently create further marginalization for those it is meant to protect. Our paper contributes by introducing a new typology of low‐literate consumer vulnerability to challenge conventional understandings of who the vulnerable consumers are in relation to their literacy level and actual marketplace behaviour. From a policy standpoint, the insights gained from our review speak to the need for differentiating low‐literate consumers in terms of their status of vulnerability, which inform public policy initiatives and effective consumer education for their empowerment and protection.
