Erving Goffman's concept of stigma refers to the social disapproval or discrimination that individuals face due to certain characteristics or traits. In his work, Goffman identifies three types of stigma: physical deformities, character flaws, and tribal affiliations. These stigmas can lead to negative perceptions and social exclusion, impacting a person's identity and interactions with others. Goffman emphasizes that stigma is not just about the individual but also about societal reactions. People with a stigma may internalize negative attitudes, leading to feelings of shame and isolation. Understanding stigma helps in addressing issues of discrimination and promoting social acceptance for marginalized groups.
