'''Social systems theory''' is a sociological framework developed by the German sociologist [[Niklas Luhmann]] (1927–1998) that applies [[Autopoiesis|autopoiesis theory]] and [[Second-Order Cybernetics]] to the study of society. Luhmann's radical claim is that societies are not composed of human beings but of communications — and that the social system is defined by the recursive production of communications by communications. Humans are in the ''environment'' of social systems, not inside them.

The framework distinguishes three types of autopoietic social systems: '''interaction systems''' (present, face-to-face communication), '''organizational systems''' (membership-based, decision-producing), and '''functional systems''' — the major differentiated subsystems of modern society: law, economy, science, politics, religion, education, art, and medicine. Each functional system is operationally closed: the legal system uses only legal operations (verdicts, contracts, statutes) to continue producing legal operations; the economy uses only economic operations (payments, prices, transactions) to continue producing economic operations. No system can ''tell'' another system what to do; it can only perturb it.

This operational closure does not mean systems are isolated. Luhmann distinguishes '''operational closure''' from '''cognitive openness''': a system cannot import the operations of another system, but it can be ''irritated'' by its environment and adapt its own operations in response. The economy does not become the legal system when a contract is signed; it selects, using its own economic logic, how to process the legal fact that a contract exists.

The theory's power is its systematic account of [[Complexity|complexity]] reduction: each functional system reduces social complexity by applying a distinctive binary code (legal/illegal, payment/non-payment, true/false, powerful/powerless) that converts the overwhelming complexity of possible communications into manageable decisions. [[Differentiation|Functional differentiation]] — the specialization of separate systems for separate social functions — is Luhmann's characterization of modernity.

Critics note that the framework is deliberately non-normative — Luhmann refuses to privilege any functional system's perspective — which makes it difficult to use for social critique. Admirers respond that this is a virtue: social theory that operates from within one functional system's code (say, the political code of power) is not sociology but ideology. Whether the theory successfully occupies a position outside all functional systems, or whether it simply imports the code of science (true/false), remains contested.
