Cybernetics

Cybernetics is a field of systems theory that studies circular causal systems whose outputs are also inputs, such as feedback systems. It is concerned with the general principles of circular causal processes, including in ecological, technological, biological, cognitive and social systems and also in the context of practical activities such as designing, learning, and managing.

The field is named after an example of circular causal feedback—that of steering a ship (the ancient Greek κυβερνήτης (''kybernḗtēs'') means "helmsperson"). In steering a ship, the helmsperson adjusts their steering in continual response to the effect it is observed as having, forming a feedback loop through which a steady course can be maintained in a changing environment, responding to disturbances from cross winds and tide.

Cybernetics' transdisciplinary character has meant that it intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.

Definitions

Cybernetics has been defined in a variety of ways, reflecting "the richness of its conceptual base." One of the most well known definitions is that of Norbert Wiener who characterised cybernetics as concerned with "control and communication in the animal and the machine." Another early definition is that of the Macy cybernetics conferences, where cybernetics was understood as the study of "circular causal and feedback mechanisms in biological and social systems." Margaret Mead emphasised the role of cybernetics as "a form of cross-disciplinary thought which made it possible for members of many disciplines to communicate with each other easily in a language which all could understand."

Other definitions include: "the art of governing or the science of government" (André-Marie Ampère); "the art of steersmanship" ( Ross Ashby); "the study of systems of any nature which are capable of receiving, storing, and processing information so as to use it for control" ( Andrey Kolmogorov); and "a branch of mathematics dealing with problems of control, recursiveness, and information, focuses on forms and the patterns that connect" (Gregory Bateson).

Etymology

The Ancient Greek term κυβερνητικός (kubernētikos, '(good at) steering') appears in Plato's ''Republic'' and '' ''Alcibiades'''', where the metaphor of a steersman is used to signify the governance of people. The French word ''cybernétique'' was also used in 1834 by the physicist André-Marie Ampère to denote the sciences of government in his classification system of human knowledge.

According to Norbert Wiener, the word ''cybernetics'' was coined by a research group involving himself and Arturo Rosenblueth in the summer of 1947. It has been attested in print since at least 1948 through Wiener's book '' Cybernetics: Or Control and Communication in the Animal and the Machine''. In the book, Wiener states:

Moreover, Wiener explains, the term was chosen to recognize James Clerk Maxwell's 1868 publication on feedback mechanisms involving governors, noting that the term ''governor'' is also derived from κυβερνήτης (''kubernḗtēs'') via a Latin corruption '' gubernator''. Finally, Wiener motivates the choice by steering engines of a ship being "one of the earliest and best-developed forms of feedback mechanisms".

History

First wave

The initial focus of cybernetics was on parallels between regulatory feedback processes in biological and technological systems. Two foundational articles were published in 1943: "Behavior, Purpose and Teleology" by Arturo Rosenblueth, Norbert Wiener, and Julian Bigelowbased on the research on living organisms that Rosenblueth did in Mexicoand the paper "A Logical Calculus of the Ideas Immanent in Nervous Activity" by Warren McCulloch and Walter Pitts. The foundations of cybernetics were then developed through a series of transdisciplinary conferences funded by the Josiah Macy, Jr. Foundation, between 1946 and 1953. The conferences were chaired by McCulloch and had participants included Ross Ashby, Gregory Bateson, Heinz von Foerster, Margaret Mead, John von Neumann, and Norbert Wiener. In the UK, similar focuses were explored by the Ratio Club, an informal dining club of young psychiatrists, psychologists, physiologists, mathematicians and engineers that met between 1949 and 1958. Wiener introduced the neologism ''cybernetics'' to denote the study of "teleological mechanisms" and popularized it through the book '' Cybernetics: Or Control and Communication in the Animal and the Machine''.

During the 1950s, cybernetics was developed as a primarily technical discipline, such as in Qian Xuesen's 1954 "Engineering Cybernetics". In the Soviet Union, Cybernetics was initially considered with suspicion but became accepted from the mid to late 1950s.

By the 1960s and 1970s, however, cybernetics' transdisciplinarity fragmented, with technical focuses separating into separate fields. Artificial intelligence (AI) was founded as a distinct discipline at the Dartmouth workshop in 1956, differentiating itself from the broader cybernetics field. After some uneasy coexistence, AI gained funding and prominence. Consequently, cybernetic sciences such as the study of artificial neural networks were downplayed. Similarly, computer science became defined as a distinct academic discipline in the 1950s and early 1960s.

Second wave

The second wave of cybernetics came to prominence from the 1960s onwards, with its focus inflecting away from technology toward social, ecological, and philosophical concerns. It was still grounded in biology, notably Maturana and Varela's autopoiesis, and built on earlier work on self-organising systems and the presence of anthropologists Mead and Bateson in the Macy meetings. The Biological Computer Laboratory, founded in 1958 and active until the mid-1970s under the direction of Heinz von Foerster at the University of Illinois at Urbana–Champaign, was a major incubator of this trend in cybernetics research.

Focuses of the second wave of cybernetics included management cybernetics, such as Stafford Beer's biologically inspired viable system model; work in family therapy, drawing on Bateson; social systems, such as in the work of Niklas Luhmann; epistemology and pedagogy, such as in the development of radical constructivism. Cybernetics' core theme of circular causality was developed beyond goal-oriented processes to concerns with reflexivity and recursion. This was especially so in the development of second-order cybernetics (or the cybernetics of cybernetics), developed and promoted by Heinz von Foerster, which focused on questions of observation, cognition, epistemology, and ethics.

The 1960s onwards also saw cybernetics begin to develop exchanges with the creative arts, design, and architecture, notably with the ''Cybernetic Serendipity'' exhibition (ICA, London, 1968), curated by Jasia Reichardt, and the unrealised Fun Palace project (London, unrealised, 1964 onwards), where Gordon Pask was consultant to architect Cedric Price and theatre director Joan Littlewood.

Third wave

From the 1990s onwards, there has been a renewed interest in cybernetics from a number of directions. Early cybernetic work on artificial neural networks has been returned to as a paradigm in machine learning and artificial intelligence. The entanglements of society with emerging technologies has led to exchanges with feminist technoscience and posthumanism. Re-examinations of cybernetics' history have seen science studies scholars emphasising cybernetics' unusual qualities as a science, such as its "performative ontology". Practical design disciplines have drawn on cybernetics for theoretical underpinning and transdisciplinary connections. Emerging topics include how cybernetics' engagements with social, human, and ecological contexts might come together with its earlier technological focus, whether as a critical discourse or a "new branch of engineering".

Key concepts and theories

The central theme in cybernetics is feedback. Feedback is a process where the observed outcomes of actions are taken as inputs for further action in ways that support the pursuit, maintenance, or disruption of particular conditions, forming a circular causal relationship. In steering a ship, the helmsperson maintains a steady course in a changing environment by adjusting their steering in continual response to the effect it is observed as having. This theme has also been carried forward in modern cybernetic theories (e.g., Cybernetic Trait Complexes Theory).

Other examples of circular causal feedback include: technological devices such as the thermostat, where the action of a heater responds to measured changes in temperature regulating the temperature of the room within a set range, and the centrifugal governor of a steam engine, which regulates the engine speed; biological examples such as the coordination of volitional movement through the nervous system and the homeostatic processes that regulate variables such as blood sugar; and processes of social interaction such as conversation.

Negative feedback processes are those that maintain particular conditions by reducing (hence 'negative') the difference from a desired state, such as where a thermostat turns on a heater when it is too cold and turns a heater off when it is too hot. Positive feedback processes increase (hence 'positive') the difference from a desired state. An example of positive feedback is when a microphone picks up the sound that it is producing through a speaker, which is then played through the speaker, and so on.

In addition to feedback, cybernetics is concerned with other forms of circular processes including: feedforward, recursion, and reflexivity.

Other key concepts and theories in cybernetics include:
* Autopoiesis
* Black box
* Conversation theory
* Double bind theory: Double binds are patterns created in interaction between two or more parties in ongoing relationships where there is a contradiction between messages at different logical levels that creates a situation with emotional threat but no possibility of withdrawal from the situation and no way to articulate the problem. Mary Catherine Bateson. (2005). The double bind: Pathology and creativity. ''Cybernetics and Human Knowing''. ''12''(1-2) The theory was first described by Gregory Bateson and colleagues in the 1950s with regard to the origins of schizophrenia,Bateson, G., Jackson, D. D., Haley, J. & Weakland, J., 1956, Toward a theory of schizophrenia.''Behavioral Science'', Vol. 1, 251–264. but it is also characteristic of many other social contexts.
* Experimental epistemology
* Good regulator theorem
* Perceptual control theory: A model of behavior based on the properties of negative feedback (cybernetic) control loops. A key insight of PCT is that the controlled variable is not the output of the system (the behavioral actions), but its input, "perception". The theory came to be known as "perceptual control theory" to distinguish from those control theorists that assert or assume that it is the system's output that is controlled. Method of levels is an approach to psychotherapy based on perceptual control theory where the therapist aims to help the patient shift their awareness to higher levels of perception in order to resolve conflicts and allow reorganization to take place.
* Radical constructivism
* Second-order cybernetics: Also known as the cybernetics of cybernetics, second-order cybernetics is the recursive application of cybernetics to itself and the practice of cybernetics according to such a critique.
* Requisite Variety
* Self-organisation
* Social systems theory
* Viable system model

Related fields and applications

Cybernetics' central concept of circular causality is of wide applicability, leading to diverse applications and relations with other fields. Many of the initial applications of cybernetics focused on engineering, biology, and exchanges between the two, such as medical cybernetics and robotics and topics such as neural networks, heterarchy. In the social and behavioral sciences, cybernetics has included and influenced work in anthropology, sociology, economics, family therapy, cognitive science, and psychology.

As cybernetics has developed, it broadened in scope to include work in management, design, pedagogy, and the creative arts, while also developing exchanges with constructivist philosophies, counter-cultural movements,Dubberly, H., & Pangaro, P. (2015). How cybernetics connects computing, counterculture, and design. In Hippie Modernism: The Struggle for Utopia. Walker Art Center. http://www.dubberly.com/articles/cybernetics-and-counterculture.html and media studies. The development of management cybernetics has led to a variety of applications, notably to the national economy of Chile under the Allende government in Project Cybersyn. In design, cybernetics has been influential on interactive architecture, human-computer interaction, design research, and the development of systemic design and metadesign practices.

Cybernetics is often understood within the context of systems science, systems theory, and systems thinking. Systems approaches influenced by cybernetics include critical systems thinking, which incorporates the viable system model; systemic design; and system dynamics, which is based on the concept of causal feedback loops.

Many fields trace their origins in whole or part to work carried out in cybernetics, or were partially absorbed into cybernetics when it was developed. These include artificial intelligence, bionics, cognitive science, control theory, complexity science, computer science, information theory and robotics. Some aspects of modern artificial intelligence, particularly the social machine, are often described in cybernetic terms.
