Passing is the ability of a person to be regarded as a member of an identity group or category, such as racial identity, ethnicity, caste, social class, sexual orientation, gender, religion, age and/or disability status, that is often different from their own. Passing may be used to increase social acceptance in order to cope with stigma by removing stigma from the presented self and could result in other social benefits as well. Thus, passing may serve as a form of self-preservation or self-protection in instances where expressing one's true or prior identity may be dangerous. Passing may require acceptance into a community and may also lead to temporary or permanent leave from another community to which an individual previously belonged. Thus, passing can result in separation from one's original self, family, friends, or previous living experiences. While successful passing may contribute to economic security, safety, and avoidance of stigma, it may take an emotional toll as a result of denial of one's previous identity and may lead to depression or self-loathing. When an individual deliberately attempts to 'pass' as a member of an identity group, they may actively engage in performance of behaviors they believe to be associated with membership of that group. Passing practices can also include information management where the passer attempts to control or conceal any stigmatizing information that may reveal disparity from their presumed identity.
Etymologically, the term is simply the nominalisation of the verb pass in its phrasal use with for or as, as in a counterfeit passing for the genuine article or an impostor passing as another person. It has been in popular use since at least the late 1920s.
Passing, as a sociological concept, was first coined by Erving Goffman as a term for one response to possessing some kind of, often less visible, stigma. Stigma, according to Goffman's framework in his work Stigma: Notes on the Management of Spoiled Identity (1963), "refer[s] to an attribute that is deeply discrediting" or "an undesired differentness from what [was] anticipated".
