The equilibrium model is Talcott Parsons's functionalist view of society as tending toward a state of stability or balance, where different parts of the social system work together to maintain overall equilibrium. Parsons argued that societies are complex systems with interdependent parts, each fulfilling certain functions that contribute to the system's survival and stability. When disruptions or changes occur in one part of the system, other parts will adjust to restore balance and maintain social order. This model emphasises the self-regulating nature of social systems and their tendency to seek a state of equilibrium. However, it has been criticised for its focus on stability and its limited attention to social conflict and social change.
