1.2 Communication as Control Process

Viewing communication as a control process means understanding communicative acts as operations by which systems—biological, psychological, social, or technological—monitor, regulate, and direct the behavior of themselves and their environments toward desired states. This perspective, rooted in cybernetics and systems theory, treats communication not as the incidental exchange of information but as the fundamental mechanism through which any organized system maintains itself, pursues goals, and adapts to change.

The Meaning of Control in Communication

The word "control" in this context does not refer to coercion or manipulation in the ordinary sense. It refers instead to the technical sense established by Norbert Wiener in cybernetics: the capacity of a system to use information about its own state to regulate its behavior with respect to a goal. Control, so understood, is a property of organization rather than power, and it is present wherever a system can sense states of affairs, compare them to reference values, and generate corrective responses.

In communication terms, every purposive exchange involves control processes:

• A speaker monitoring listener feedback (facial expression, posture, verbal response) and adjusting their message accordingly is exercising communicative control.
• An organization issuing policies, receiving reports, and modifying procedures in response to outcomes is a communication-based control system.
• A regulatory agency monitoring media content and issuing compliance guidelines constitutes a control process at the institutional level.
• A social norm—an internalized standard to which behavior is compared and according to which deviations are corrected—is a control mechanism distributed across communicative participants.

The Control Loop in Communication

The generic structure of a control process in communication involves the following elements operating in a loop:

Reference state (goal or standard): The value toward which the system aims. In communication, reference states may include desired relational states ("mutual respect"), content goals ("accurate understanding"), or behavioral targets ("compliance with instructions").

Sensor (monitor): The component that detects the current state of the relevant variable. In human communication, sensory systems, attention, and interpretive frameworks serve this function. In organizational communication, reporting systems and performance metrics serve as sensors.

Comparator: The component that computes the error—the discrepancy between the current state and the reference state. In interpersonal communication, this comparison occurs cognitively; in technical systems, it is performed by dedicated comparator circuits.

Effector (actuator): The component that generates action to reduce the error. In communication, the effector is the production of messages, the adjustment of tone, the revision of an argument, or the redesign of a process.

Feedback channel: The pathway through which information about the current state is returned to the comparator. Without a feedback channel, the system cannot know the effect of its corrective actions and cannot maintain control.

This loop is represented schematically as:

Types of Communication Control

Behavioral Control

The most direct form involves one communicator attempting to modify the behavior of another. Instructions, commands, requests, prohibitions, and persuasive messages are all forms of behavioral control. What distinguishes communication as control from mere information transfer is the intention to bring the other's behavior into alignment with a reference state.

The effectiveness of behavioral control through communication depends on:

• The precision with which the reference state is specified and transmitted.
• The accuracy with which the target interprets and responds to the control signal.
• The quality of feedback that informs the controller whether the desired behavior has occurred.
• The authority or relational context that makes compliance normatively appropriate.

Cognitive Control

Communicative control operates at the level of beliefs, attention, and perception, not only overt behavior. Framing, priming, agenda-setting, and persuasion all work by shaping the cognitive reference states against which receivers evaluate their own conditions and options. A public health campaign that makes people aware of risks associated with certain behaviors is exercising cognitive control by introducing new reference states (healthy behavior as a norm) against which existing behaviors are compared and found deficient.

Relational Control

In interpersonal communication, control is often exercised at the relational rather than content level. Dominance, complementarity, and symmetry in relationships are patterns of relational control: who defines the terms of interaction, who accepts the definitions offered, who claims the right to determine what topics are discussed and how they are framed. Metacommunicative signals—voice tone, turn-taking behavior, interruptions, gaze—are among the primary channels through which relational control is enacted.

Institutional and Organizational Control

Organizations coordinate action through communication-based control systems: policies, procedures, performance metrics, reporting structures, and monitoring mechanisms all constitute information-based regulatory loops. The classical cybernetic analysis of organization by Stafford Beer (Viable System Model) describes organizations as hierarchically nested control loops in which higher-order loops regulate the reference states of lower-order loops, enabling the system to manage complexity while maintaining coherent direction.

Communication, Control, and Autonomy

A critical tension in understanding communication as control arises with respect to human autonomy and agency. If communication is a control mechanism, does this mean that communicative actors are merely nodes in regulatory loops, their behavior determined by feedback from others and from structural constraints? Cybernetic theorists respond to this concern in several ways:

• They note that control loops are mutual: in any interaction, each party is simultaneously controller and controlled, sender and receiver of feedback. Control is not unidirectional but circular.
• They distinguish between control of behavior (bringing output into alignment with external reference states) and self-regulation (the autonomous maintenance of self-generated reference states), arguing that genuine autonomy involves the capacity to set and maintain one's own goals, not the absence of all feedback sensitivity.
• Second-order cybernetics emphasizes that human observers are themselves constitutive of the systems they participate in, and that the capacity for self-observation and self-modification introduces genuine reflexive agency into the picture.

Error, Noise, and Communication Failure

The control-process perspective provides precise accounts of communication failure. Failures arise from:

Sensor inadequacy: Misreading feedback signals. A speaker misinterprets audience skepticism as attention and continues in an unsuccessful direction.

Comparator error: Applying the wrong reference state. A manager evaluates employee communication against norms appropriate to a different context.

Effector limitation: Lacking the behavioral repertoire to generate effective corrective responses. A communicator who knows their message is not landing but has no alternative way to frame it.

Feedback delay: When feedback about outcomes arrives so late that corrective action is delayed past the point where it can be effective, control degrades. Delayed feedback in communication—late performance reviews, slow survey results, lagged market responses—systematically reduces the effectiveness of communication-based regulation.

Channel noise: Interference that degrades the signal, preventing accurate sensing of the current state.

Hierarchical Control and the Levels of Communication

Cybernetic control processes in communication are typically hierarchically organized. Lower-level loops regulate fast, moment-to-moment variation (word choice, syntax, gesture); higher-level loops regulate slower variables (topic, relationship stance, strategic direction). Higher-level loops set the reference states that lower-level loops pursue. This hierarchical organization is what allows complex, extended communicative processes—negotiations, therapies, organizational campaigns—to maintain overall coherence while adapting locally to moment-to-moment variation.

Understanding communication as a control process thus provides a rigorous analytical framework for understanding purpose, feedback, adaptation, and failure in any domain where organized communication takes place.
