Overview

Social stigma is a set of negative beliefs, labels and reactions that society or a group applies to people who are perceived as different or undesirable. Stigma can be overt—open discrimination and exclusion—or subtle, such as stereotyping, avoidance or whispered judgments. Public attitudes and institutional policies both shape how stigma is experienced.

Common types and characteristics

Scholars identify several forms of stigma. The sociologist Erving Goffman offered a widely used classification with three broad categories:

  • Physical differences — visible conditions or traits that attract negative attention, for example obesity or leprosy.
  • Traits and behaviors — personal attributes that are judged morally or medically, such as mental illness, drug addiction, or alcoholism.
  • Group-based ("tribal") stigma — negative attitudes attached to membership in an ethnic, national or religious group, for example prejudice against an ethnic group, a nationality, or a particular religion.

History and theoretical notes

The modern study of stigma grew from mid-20th century sociology and psychology. Researchers have described how labeling, stereotyping and power differences interact to produce status loss and discrimination. Cultural myths, fear of contagion or moral judgments often sustain stigma, while laws and institutions can either reinforce or reduce it.

Effects, examples and importance

Stigma has practical consequences: it can limit employment, access to health care, social support and legal rights. People who are stigmatized may hide conditions, delay seeking treatment, or suffer mental health declines. Examples include workplace bias against people with a history of substance use, reduced services for those with certain diseases, and social exclusion linked to racial or religious prejudice. Understanding stigma is essential for public health, education and social policy.

Addressing stigma and notable distinctions

Reducing stigma involves public education, anti-discrimination laws, inclusive services and community engagement. Interventions that combine policy change with personal contact and accurate information tend to be most effective. It is important to distinguish stigma (a social response) from the underlying condition (a health issue or characteristic) so that responses focus on rights and support rather than blame.
