 Social norms become less powerful as a structuring mechanism as populations grow, as they become more difficult to enforce, and as more new members who do not follow these norms enter the society.These new developments mean that social organizations, which have clear membership and enforcement measures, must be more heavily relied upon to govern the inmate society.These organizations typically take the form of prison gangs, which are initially formed to provide protection to their members, as these members can no longer rely on norms or correctional officials to do the same.
