answer:Well, I would argue that in a complex system, behaviours emerge in a non-linear, stochastic fashion. Social norms are a manifestation of the emergent behaviour of a system composed of people and their environments interacting as part of a complex system. This leads me to a weak-determinist position on social norms. No one is responsible for their existence, although their manifestations are not predictable given knowledge of the constituents of the system. The criteria for determining their worth are less criteria than they are observations of whether they cause the system to attempt to self-correct.
