Social Systems Theory

👥 Sociology By CampusDown Wiki Editorial Team Last updated
Quick answer: social systems theory sees society as a system of interconnected parts that maintains and changes itself through interaction with its environment. Parsons argued that every social system must meet four functions (AGIL): adaptation, goal attainment, integration and latency. Luhmann recast society as an autopoietic system that reproduces itself through communication.

Overview

Social systems theory applies the system concept of general systems theory to society, analysing social units such as families, organizations, communities and states as systems. In sociology the best-known versions are Talcott Parsons's structural functionalism and Niklas Luhmann's systems theory; in social work it is a basic lens for understanding the interaction between people and their environments.

Parsons's social system

In The Social System (1951) Parsons treated society as a system in which interaction between actors is stabilized by institutionalized roles and norms. The action system is divided into the behavioural organism, personality, social and cultural systems, and the social system is one of these.

  • AGIL scheme: developed with Bales and Shils around Working Papers in the Theory of Action (1953), the scheme holds that every system must solve four functional problems: Adaptation (securing resources from the environment – the economy), Goal attainment (setting goals and mobilizing resources – the polity), Integration (coordinating parts – law and the societal community) and Latency (maintaining values and motivation and managing tension – family, education, religion).
  • Pattern variables: Parsons and Shils (1951) set out five pairs of choices actors face in roles: affectivity vs affective neutrality, self-orientation vs collectivity-orientation, particularism vs universalism, ascription vs achievement, and diffuseness vs specificity. Traditional societies lean toward the first of each pair, modern societies toward the second.

Because it views society as a system tending toward equilibrium, Parsons's theory became the standard example of functionalism.

Luhmann's social systems theory

The German sociologist Niklas Luhmann rebuilt systems theory in Soziale Systeme (1984). A system exists through its distinction from its environment and reduces the environment's complexity. The elements of social systems are not people but communications, and social systems are autopoietic: they produce their own elements. Modern society is functionally differentiated into subsystems such as the economy, law, politics, science and education, each operating with its own code (for example legal/illegal or true/false).

Use in social work

In Human Behavior in the Social Environment: A Social Systems Approach (1974), Anderson and Carter analysed individuals, families, groups, organizations and communities as social systems. Concepts often used in this framework include:

  • Holon: every system is at once a suprasystem of smaller systems and a subsystem of a larger one, both whole and part.
  • Synergy: interaction within and across the system increases available energy so the system can maintain and grow itself.
  • Boundary, input–throughput–output, feedback, homeostasis, entropy and negentropy: concepts drawn from general systems theory, explained in the general systems theory article.

The approach locates problems in person–environment interaction rather than inside the individual, and it laid the groundwork for ecological systems theory and family systems theory.

Criticism

Parsons was criticized for overemphasizing equilibrium and consensus, failing to explain conflict, power and rapid change, and justifying the status quo. Luhmann was criticized as extremely abstract and for erasing individuals and agency, and his debate with Habermas set him against critical social theory. In social work, the system concept is so broad that it does not directly yield specific intervention methods.
