Final answer:
The 'emergent-norm' is not one of Neil Smelser's six basic preconditions for collective behavior; rather, it is part of a different theory on the matter.
Step-by-step explanation:
The six basic preconditions for collective behavior as identified by Neil Smelser do not include the 'emergent-norm'. According to Smelser's value-added theory, which is a functionalist perspective theory, the required conditions for collective behavior to take place are: structural conduciveness, structural strain, growth and spread of a generalized belief, precipitating factors, mobilization for action, and social control. 'Emergent-norm' is actually a different theory on collective behavior that emphasizes the importance of social norms.
