Stigma refers to a socially constructed process through which a characteristic, identity, condition or association becomes negatively marked and linked to devaluation, stereotyping, social distancing or exclusion. The concept is strongly associated with sociologist Erving Goffman, whose work examined how a socially discrediting attribute can alter how a person is perceived and treated. Stigma is not simply a personal feeling of embarrassment or shame. It depends on social meanings, cultural expectations and relationships between people and groups.
A characteristic becomes stigmatising when a social context attaches negative significance to it and treats the affected person as somehow diminished, undesirable or outside an accepted norm. Stigma can concern visible characteristics, concealed characteristics, behaviour, illness, occupation, poverty, identity, family circumstances or association with a stigmatised group. Its meaning therefore varies substantially across historical periods and cultures.
Goffman's distinction between discredited and discreditable identities is particularly important for understanding stigma. A discredited identity is already known or immediately apparent to others, whereas a discreditable identity is potentially concealable and may become known through disclosure or discovery. People with concealable characteristics may therefore engage in information management, selective disclosure or decisions about whether to reveal aspects of their identity.
Stigma can also involve what Goffman described as spoiled social identity, meaning that a particular attribute can dominate other aspects of how someone is perceived. This does not mean the characteristic objectively reduces a person's worth. Rather, the social reaction can narrow the range of identities recognised by others. Stigma can therefore be understood as a relational phenomenon involving classification, expectation, social judgement and unequal interaction rather than simply an attribute residing inside an individual.
Sociological research commonly distinguishes enacted stigma, anticipated stigma and internalised stigma. Enacted stigma refers to actual discriminatory or exclusionary treatment experienced because of a stigmatised characteristic. Anticipated stigma concerns expectations that disclosure or visibility will result in rejection, discrimination or negative judgement. Internalised stigma occurs when individuals adopt or absorb negative social beliefs about the category to which they belong and apply those beliefs to themselves. These forms can reinforce one another.
A person who has experienced rejection may anticipate further rejection, conceal information and eventually internalise negative messages. Conversely, supportive relationships, collective identities and positive representation can weaken internalised stigma and provide alternative interpretations. Distinguishing these mechanisms is useful because reducing discriminatory behaviour, changing social attitudes and supporting individual self acceptance involve related but different interventions.
Stigma can operate through several mechanisms, including labelling, stereotyping, separation, status loss and discrimination. Labelling assigns a socially meaningful category to a person, while stereotyping associates that category with generalised beliefs. Separation establishes a social boundary between the stigmatised group and an assumed normal group. Status loss occurs when the label lowers perceived social standing, while discrimination converts negative evaluations into differential treatment. These mechanisms can operate in everyday interaction as well as through institutions.
Stigmatising labels can influence employment decisions, healthcare interactions, educational expectations, housing opportunities and interpersonal relationships. Institutional language and administrative categories can sometimes unintentionally reinforce stigma when they define people primarily through deficits or problems. For this reason, stigma research examines not only individual prejudice but also the organisational and cultural systems that make particular classifications socially consequential.
Stigma is particularly important in relation to health, disability and mental health because fear of social judgement can influence whether people disclose symptoms, seek assistance or remain engaged with services. However, the effects differ across conditions and social contexts. A person may experience visible stigma from others, anticipated stigma before an interaction, or self stigma arising from internalised negative cultural beliefs. Concealment can protect someone from immediate discrimination but can also create stress, reduce access to support and complicate relationships.
Disclosure can increase authenticity and social support in some environments while exposing a person to discrimination in others. These trade offs demonstrate that stigma management is context dependent rather than governed by a universal strategy. Professional communication, accurate public information, peer support and institutional practices that treat people as whole individuals can influence whether a characteristic becomes socially dominant in an interaction.
Stigma can also operate at group and community levels. Certain occupations, neighbourhoods, social classes, ethnic groups, religions or forms of behaviour may acquire negative reputations that affect everyone associated with them. This can produce territorial stigma, where a geographical area is treated as inherently problematic, or courtesy stigma, where people experience negative judgement because of their association with a stigmatised person or group. Stigma can therefore affect families and communities as well as individuals.
It can also influence political and institutional priorities by determining whose experiences are treated as legitimate, credible or worthy of resources. Social movements frequently attempt to challenge stigma through collective identity, public visibility, counter narratives and changes in language. Such movements can transform a previously negative category into a source of solidarity, political mobilisation or pride, although the success and effects of these strategies vary by context.
Stigma is historically variable because the attributes considered discrediting are not fixed. Characteristics that were heavily stigmatised in one period can become normalised, while new forms of stigma can emerge when social values, institutions or technologies change. Language is especially important because terminology can either reinforce negative categorisation or provide more neutral and person centred descriptions. Nevertheless, simply changing terminology does not necessarily remove stigma if underlying social relationships remain unchanged.
Stigma is sustained by power because groups with greater institutional influence can more effectively define categories, establish norms and determine whose behaviour is considered acceptable. This means stigma should not be understood only as an interpersonal attitude. It can involve cultural representations, institutional rules, economic consequences and unequal authority over classification. Studying these dimensions helps explain why some forms of stigma persist despite widespread formal opposition to discrimination.
Stigma should be distinguished from shame, prejudice, discrimination and stereotyping. Shame is an emotional experience, whereas stigma is a social process that can produce shame but does not require it. Prejudice concerns negative attitudes, discrimination concerns differential treatment, and stereotypes concern generalised beliefs. Stigma can encompass all of these processes but is conceptually broader because it focuses on the social devaluation attached to an identity or characteristic.
Anti stigma approaches therefore operate at multiple levels, including education, contact between groups, representation, legal protection, institutional reform and support for affected communities. Interpersonal contact can challenge stereotypes when it involves meaningful relationships rather than superficial exposure. Structural reforms can reduce the material consequences of stigma even when cultural attitudes change more slowly. A comprehensive understanding therefore treats stigma as a dynamic relationship between cultural meaning, social interaction, institutional power and individual experience.
