Asociality refers to the lack of motivation to engage in social interaction, or a preference for solitary activities. Developmental psychologists use the synonyms nonsocial, unsocial, and social disinterest. Asociality is distinct from but not mutually exclusive to anti-social behaviour, in which the latter implies an active misanthropy or antagonism toward other people or the general social order. A degree of asociality is routinely observed in introverts, while extreme asociality is observed in people with a variety of clinical conditions.
Asociality is not necessarily perceived as a totally negative trait by society, since asociality has been used as a way to express dissent from prevailing ideas. It is seen as a desirable trait in certain monastic traditions, notably in Catholicism, Buddhism and Sufism.
Introversion is "the state of or tendency toward being wholly or predominantly concerned with and interested in one's own mental life". Some popular writers have characterized introverts as people whose energy tends to expand through reflection and dwindle during interaction.
The black triangle was a badge used in Nazi concentration camps to mark prisoners as "asocial" or "arbeitsscheu" (work-shy). It was later adopted as a lesbian or feminist symbol of pride and solidarity, on the assumption that the Nazis included lesbians in the "asocial" category. More recently it has been adopted by UK disabled people's organisations responding to increasing press allegations that disabled benefit recipients are workshy.
The symbol originates from Nazi concentration camps, where every prisoner had to wear one of the Nazi concentration camp badges on their jacket, the color of which categorized them according to "their kind." Individuals deemed "asocial" had to wear the Black Triangle. Many Black Triangle prisoners were either mentally disabled or mentally ill. The homeless were also included, as were alcoholics, the habitually "work-shy," prostitutes, and others (including draft dodgers and pacifists).
Lesbians have over time claimed the black triangle as a symbol of defiance against repression and discrimination, and it is considered a counterpart to the gay pink triangle. Lesbians in Germany and the United States began reclaiming the black triangle as a pride symbol in the 1980s.
