Alternative_Cultural_Formations_And_Behaviour represents social phenomena that emerge as variations, challenges, or alternatives to dominant cultural patterns and mainstream social arrangements. This class encompasses subcultures that deliberately oppose mainstream values (Counterculture, Deviant_Subculture), alternative relationship arrangements that exist outside traditional marriage (Cohabitation), and dynamic cultural expressions that reflect temporary collective preferences (Fashion). It also includes informal behavioural norms that guide everyday social interaction (Folkway) and theoretical concepts that explain unintended social consequences (Latent_Function). These phenomena demonstrate the diversity and adaptability of human social organisation, showing how societies accommodate difference, manage deviance, and generate new forms of cultural expression. This grouping highlights the dynamic tension between conformity and innovation that characterises all social systems.
