transdisciplinary study of circular causal processes such as

managing. Cybernetics' transdisciplinary
character has meant that it
intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.
The field is named after an example of circular causal feedback—that of steering a ship (the ancient
Greek κυβερνήτης (''kybernḗtēs'') refers to the person who steers a ship). In steering a ship, the position of the rudder is adjusted 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 has its origins in exchanges between numerous disciplines during the
1940s. Initial developments were consolidated through meetings such as the
Macy Conferences and the
Ratio Club. Early focuses included purposeful behaviour, neural networks,
heterarchy,
information theory

Definitions
Cybernetics has been defined in a variety of ways, reflecting "the richness of its conceptual base." One of the best known definitions is that of the American scientist
Norbert Wiener
Norbert Wiener (November 26, 1894 – March 18, 1964) was an American computer scientist, mathematician, and philosopher. He became a professor of mathematics at the Massachusetts Institute of Technology ( MIT). A child prodigy, Wiener late ...
, 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).

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

, noting that the term ''governor'' is also derived from κυβερνήτης (''kubernḗtēs'') via a Latin corruption ''

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
John von Neumann ( ; ; December 28, 1903 – February 8, 1957) was a Hungarian and American mathematician, physicist, computer scientist and engineer. Von Neumann had perhaps the widest coverage of any mathematician of his time, in ...

Norbert Wiener
Norbert Wiener (November 26, 1894 – March 18, 1964) was an American computer scientist, mathematician, and philosopher. He became a professor of mathematics at the Massachusetts Institute of Technology ( MIT). A child prodigy, Wiener late ...
. 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
Artificial intelligence (AI) is the capability of computer, computational systems to perform tasks typically associated with human intelligence, such as learning, reasoning, problem-solving, perception, and decision-making. It is a field of re ...
(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.

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
Niklas Luhmann (; ; December 8, 1927 – November 11, 1998) was a German sociologist, philosopher of social science, and systems theorist.
Niklas Luhmann is one of the most influential German sociologists of the 20th century. His thinking was ...
; 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 science and philosophy, a paradigm ( ) is a distinct set of concepts or thought patterns, including theories, research methods, postulates, and standards for what constitute legitimate contributions to a field. The word ''paradigm'' is Ancient ...

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
Ontology is the philosophical study of existence, being. It is traditionally understood as the subdiscipline of metaphysics focused on the most general features of reality. As one of the most fundamental concepts, being encompasses all of realit ...
". 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 occurs when outputs of a system are routed back as inputs as part of a chain of cause and effect that forms a circuit or loop. The system can then be said to ''feed back'' into itself. The notion of cause-and-effect has to be handle ...
. 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.
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
In biology, the nervous system is the complex system, highly complex part of an animal that coordinates its behavior, actions and sense, sensory information by transmitting action potential, signals to and from different parts of its body. Th ...
and the
homeostatic processes that regulate variables such as blood sugar; and processes of social interaction such as conversation.
Negative feedback
Negative feedback (or balancing feedback) occurs when some function (Mathematics), function of the output of a system, process, or mechanism is feedback, fed back in a manner that tends to reduce the fluctuations in the output, whether caused ...
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
Recursion occurs when the definition of a concept or process depends on a simpler or previous version of itself. Recursion is used in a variety of disciplines ranging from linguistics to logic. The most common application of recursion is in m ...

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.

* Experimental epistemology
*
Good regulator theorem
*
Heterarchy

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.

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,

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.
