Niklas Luhmann: systems theory

• A. The individual human being
• B. Communication ✓
• C. Social class
• D. Institutions of the state

Why: Luhmann argued that society consists of communications, not individuals. Individuals belong to the environment of social systems, while communication is the element that reproduces social systems.

• A. A system has a fixed physical location
• B. A system is a boundary-maintaining difference between itself and its environment ✓
• C. A system is always controlled by a central authority
• D. A system consists only of human participants

Why: Luhmann defined systems through the difference between system and environment. Systems maintain themselves by drawing and reproducing this boundary, which he described as a self-referential operation.

• A. Systems are designed by external planners
• B. Systems produce their own elements through their own operations, reproducing themselves ✓
• C. Systems are copied from one society to another
• D. Systems depend entirely on biological reproduction

Why: Borrowed from biologists Maturana and Varela, autopoiesis describes self-production: social systems reproduce their components (communications) using those same components, making them operationally closed.

• A. Solidarity
• B. Contingency
• C. Reduction of complexity ✓
• D. Hegemony

Why: Luhmann held that systems exist because the world offers more possibilities than can be actualized. Systems select and filter possibilities, thereby reducing complexity to a manageable level.

• A. Social systems are made of thoughts, psychic systems are made of communication
• B. Social systems operate through communication, psychic systems operate through consciousness ✓
• C. Social systems are temporary, psychic systems are permanent
• D. There is no difference; they are the same type of system

Why: Luhmann distinguished operationally closed systems by their elements: social systems reproduce through communication, while psychic systems reproduce through thought and consciousness. Each is part of the other's environment.

• A. A system's ability to import energy from its environment without any internal processing
• B. A system that produces its own elements through the network of those same elements
• C. The design of systems by external engineers to achieve specified goals
• D. The imitation of biological processes in mechanical machines

• A. Structural coupling
• B. Equilibrium
• C. Feedback amplification
• D. Input-output mapping

• A. A system describing itself in order to distinguish itself from its environment
• B. A researcher referring to their own biography when analyzing data
• C. A system copying the structure of another system
• D. A text quoting its own earlier passages

• A. Individual persons
• B. Actions of organizations
• C. Communications
• D. Physical objects

• A. A system cannot receive any information from its environment
• B. A system's operations are produced only by the system itself, though it remains open to environmental stimuli
• C. A system is sealed off from all change over time
• D. A system's boundaries are fixed by external law

• A. Individual human beings
• B. Communication ✓
• C. Social norms
• D. Actions taken by persons

Why: Luhmann argues that social systems are composed of communications, not people. Humans belong to the environment of social systems, while communication is the operation that reproduces the system itself.

• A. Sender, receiver, and medium
• B. Information, utterance, and understanding ✓
• C. Input, process, and output
• D. Stimulus, response, and feedback

Why: Luhmann defines communication as the unity of information, utterance, and understanding (Verstehen). Information is the selection of what is conveyed, utterance is the act of conveying it, and understanding is the difference between the two that is drawn by the receiver.

• A. Because people are too unpredictable to study
• B. Because social systems consist of communications, and persons belong to the system's environment ✓
• C. Because only institutions count as social systems
• D. Because people only act individually and never socially

Why: For Luhmann, social systems are made up of communications linked to one another. Psychic systems (human consciousness) are operationally closed and form part of the environment of the social system, so individuals are not components of it.

• A. Communication is controlled by a central authority
• B. Communication produces further communication, so the social system reproduces itself through its own operations ✓
• C. Communication copies itself exactly from one generation to the next
• D. Communication depends entirely on the biological needs of humans

Why: Autopoiesis means self-production. Each communication connects to previous communications and calls forth subsequent ones, so the social system continually reproduces itself through its own elements, operating as a closed yet environmentally open system.

• A. Understanding means that the receiver agrees with the message
• B. Understanding is the difference between information and utterance drawn by the receiver, and it does not require agreement ✓
• C. Understanding is only possible when sender and receiver share identical minds
• D. Understanding is a psychic process that is not part of communication at all

Why: Luhmann treats understanding as the receiver's distinction between what was said (information) and the fact that it was said (utterance). Understanding does not imply acceptance or agreement; one can understand a communication and reject it, and communication still occurs.

• A. Stratificatory differentiation based on social rank
• B. Functional differentiation into subsystems such as economy, law, science, and politics ✓
• C. Segmentary differentiation into identical clans or villages
• D. Centre-periphery differentiation based on geographic regions

Why: Luhmann argues that modern society differentiates primarily along functional lines, with subsystems like the economy, law, science, and politics each organized around a specific function and binary code.

• A. A computer programming language used by institutions
• B. A two-valued distinction (e.g., payment/non-payment in the economy, true/false in science) that structures communication within a subsystem ✓
• C. A secret cipher used by government agencies
• D. A numerical rating system for measuring social status

Why: Binary codes are the two-valued distinctions that each functional subsystem uses to sort communications, such as government/opposition in politics or legal/illegal in law, giving the system its operational logic.

• A. They are physically isolated from one another in separate buildings
• B. They reproduce their own elements through their own operations and do not directly import the operations of other systems ✓
• C. They refuse to accept any input from the environment
• D. They are controlled by a single central authority

Why: Operational closure means each system produces its own communications using its own code and programs, so it cannot simply take over operations of another system, though it remains open to environmental irritations.

• A. A function is a ceremonial ritual that binds society together
• B. A function is a problem reference that a subsystem addresses, such as securing collectively binding decisions for politics or scarcity management for the economy ✓
• C. A function is the personal purpose of an individual actor
• D. A function is a mathematical formula used to predict social change

Why: For Luhmann, functions are not moral goals but the societal problems that a given subsystem specializes in handling, and each subsystem develops its own solutions to its distinctive function.

• A. Luhmann rejects the idea that society has any structure at all
• B. Luhmann sees society as a network of communications organized into self-referential subsystems, rather than as a set of interdependent parts serving a shared social integration ✓
• C. Luhmann believes society should return to traditional segmentary forms
• D. Luhmann argues that differentiation is caused exclusively by economic forces

Why: Luhmann moves away from Parsons' structural-functionalist model of integrated parts by treating society as a system of communications, where subsystems are self-referential and no single subsystem stands at the top of the hierarchy.

• A. To guarantee that all communications between people are accurate and true
• B. To reduce the overwhelming complexity of the world by selecting possibilities and making them manageable ✓
• C. To express the emotional intentions of individual psychic systems
• D. To establish a fixed hierarchy of values that governs social organization

Why: For Luhmann, meaning is a form that organizes experience by actualizing some possibilities while keeping others open as horizons. Its core function is reducing complexity, making the vast range of possible experiences and actions tractable for systems.

• A. The situation in which two systems are contingent on the same external event
• B. The condition in which each party's action depends on how the other party will respond to it, and vice versa ✓
• C. The duplication of communication channels to ensure that messages are received
• D. The fact that every social rule has both a legal and a moral dimension

Why: Double contingency arises when ego's behavior depends on alter's reaction and alter's behavior depends on ego's reaction. Neither can know the other's choice in advance, which Luhmann treats as a fundamental problem that social systems must solve for communication to begin.

• A. Through the direct transfer of intentions from one consciousness to another
• B. Through the emergence of shared generalized expectations and the structuring of meaning that makes interaction possible ✓
• C. Through the enforcement of uniform behavior by a central authority
• D. Through agreement on a common biological instinct shared by all participants

Why: Luhmann argues that double contingency is resolved not by mutual understanding of inner states but by the development of stable expectations and shared meaning structures. These allow communication to proceed even though the minds involved remain opaque to each other.

• A. The technical difficulty of understanding modern machinery and computing systems
• B. The excess of possible events, relations, and actions that exceeds what any system can actually realize at a given time ✓
• C. The moral confusion produced by competing ethical traditions in society
• D. The number of different languages spoken within a single nation

Why: For Luhmann, complexity means that there are always more possibilities than can be actualized. Systems exist precisely to select among these possibilities and reduce the complexity to a manageable level, which is why he sees system formation as a response to the world's excess of possibilities.

• A. The environment is a passive backdrop that systems simply observe without affecting
• B. A system is defined by a boundary that distinguishes it from its environment, and the environment always exceeds the system in complexity ✓
• C. Systems and environments are identical, since everything is part of one universal system
• D. The environment contains only other social systems, while nature is irrelevant to systems theory

Why: Luhmann's theory is built on the difference between system and environment. A system maintains its identity by drawing a boundary, and the environment is always more complex than the system, so systems must continually reduce environmental complexity to operate.

• A. Drawing a distinction that separates a marked side from an unmarked side
• B. Reducing the complexity of the environment through direct sensory perception
• C. Transmitting information from one subsystem to another without loss
• D. Establishing consensus among communicating participants about shared meanings

• A. The external environment of the system
• B. The observer's own internal memory
• C. The unmarked side of the distinction used to observe
• D. The future outcomes of the communication

• A. An observer who observes the observations made by another observer, including how that observer draws distinctions
• B. A system that observes the environment twice to verify accuracy
• C. An external scientist who studies society from outside all social systems
• D. A subsystem that monitors the output of a first-order subsystem for errors

• A. Because the second-order observer can see what the first observer could not see, namely the distinction the first observer used
• B. Because second-order observers have access to more sensory data than first-order observers
• C. Because second-order observers are immune to the limits of perception
• D. Because they can observe the unconscious motives of other people

• A. The observer stands outside the system and describes it objectively
• B. The observer is always inside the system, so observation is never neutral or fully transparent
• C. The observer's position is determined entirely by the social roles they occupy
• D. Observers can eliminate their biases through rigorous method

• A. Communication
• B. Individual decision-making
• C. Physical interaction between people
• D. Emotional bonding between members

• A. Structural coupling
• B. Binary coding
• C. Lifeworld rationalization
• D. Double contingency

• A. Profitable/unprofitable
• B. True/false
• C. Lawful/unlawful
• D. Powerful/powerless

• A. They are isolated from their environment and cannot be affected by it
• B. They reproduce themselves using their own operations, though they remain open to environmental influence
• C. They are controlled entirely by the state
• D. They cannot communicate with other social systems

• A. Structural coupling
• B. Autopoietic reproduction
• C. Functional equivalence
• D. Second-order observation
