retreatism
Retreatism is a sociological and criminological term for one of Robert K. Merton's five modes of adaptation to anomie. It describes a response to the discrepancy between culturally prescribed goals and the institutionalized means of achieving them: individuals who reject both the goals (such as wealth, status) and the means (employment, education) and withdraw from mainstream society. Retreatists may disengage from social roles and norms, narrowing their social world to a private sphere and often leading to isolation, homelessness, or chronic substance use; some may join insular subcultures or live as long-term dependents on others or on withdrawal from social participation.
In Merton’s framework, retreatism sits alongside conformity, innovation, ritualism, and rebellion. Ritualists still follow established rules
Critics note that retreatism can be difficult to observe and may overlap with other forms of deviance
