Cybernetics is the
interdisciplinary study of the
structure of
regulatory systems. As an oversimplification, Cybernetics is
information theory,
control theory and
systems theory, at least in its first-order form. (
Second-order cybernetics has crucial methodological and epistemological implications that are fundamental to the field as a whole.) Both in its origins and in its evolution in the second half of the 20th century, cybernetics is equally applicable to physical and social (that is, language-based) systems.

Cybernetics is only applicable when the system being analysed is involved in a closed signal loop; that is, where action by the system causes some change in its environment and that change is fed to the system via information (feedback) that enables the system to change its behavior. This "circular causal" relationship is necessary and sufficient for a cybernetic perspective.
System Dynamics, a related field, originated with applications of electrical engineering control theory to other kinds of simulation models (especially business systems) by
Jay Forrester at
MIT in the 1950s.
Contemporary cybernetics began as an interdisciplinary study connecting the fields of control systems, electrical network theory, mechanical engineering, logic modeling, evolutionary biology, neuroscience, anthropology, and psychology in the 1940s, often attributed to the Macy Conferences.
Other fields of study which have influenced or been influenced by cybernetics include game theory, system theory (a mathematical counterpart to cybernetics), perceptual control theory, sociology, psychology (especially neuropsychology, behavioral psychology, cognitive psychology), philosophy, and architecture and organizational theory.
The term ''cybernetics'' stems from the
Greek κυβερνήτης (''kybernētēs'', steersman, governor, pilot, or rudder — the same root as
government). Cybernetics is a broad field of study, but the essential goal of cybernetics is to understand and define the functions and processes of systems that have goals and that participate in circular,
causal chains that move from action to sensing to comparison with desired goal, and again to action. Studies in cybernetics provide a means for examining the design and function of any system, including social systems such as business management and organizational learning, including for the purpose of making them more
efficient and
effective.
Cybernetics was defined by Norbert Wiener, in his book of the same title, as the study of control and communication in the animal and the machine. Stafford Beer called it the science of effective organization and Gordon Pask called it "the art of defensible metaphors" (emphasizing its constructivist epistemology) though he later extended it to include information flows "in all media" from stars to brains. It includes the study of feedback, black boxes and derived concepts such as communication and control in living organisms, machines and organizations including self-organization. Its focus is how anything (digital, mechanical or biological) processes information, reacts to information, and changes or can be changed to better accomplish the first two tasks.
A more philosophical definition, suggested in 1956 by Louis Couffignal, one of the pioneers of cybernetics, characterizes cybernetics as "the art of ensuring the efficacy of action." The most recent definition has been proposed by Louis Kauffman, President of the American Society for Cybernetics, "Cybernetics is the study of systems and processes that interact with themselves and produce themselves from themselves."
Concepts studied by cyberneticists (or, as some prefer, cyberneticians) include, but are not limited to: learning, cognition, adaption, social control, emergence, communication, efficiency, efficacy and connectivity. These concepts are studied by other subjects such as engineering and biology, but in cybernetics these are removed from the context of the individual organism or device.
The word ''cybernetics'' was first used in the context of "the study of self-governance" by
Plato in
The Alcibiades to signify the
governance of people. The word 'cybernétique' was also used in 1834 by the physicist
André-Marie Ampère (1775–1836) to denote the sciences of government in his classification system of human knowledge.
The first artificial automatic regulatory system, a
water clock, was invented by the mechanician
Ktesibios. In his water clocks, water flowed from a source such as a holding tank into a reservoir, then from the reservoir to the mechanisms of the clock. Ktesibios's device used a cone-shaped float to monitor the level of the water in its reservoir and adjust the rate of flow of the water accordingly to maintain a constant level of water in the reservoir, so that it neither overflowed nor was allowed to run dry. This was the first artificial truly automatic self-regulatory device that required no outside intervention between the feedback and the controls of the mechanism. Although they did not refer to this concept by the name of Cybernetics (they considered it a field of engineering),
Ktesibios and others such as
Heron and
Su Song are considered to be some of the first to study cybernetic principles.
The study of ''teleological mechanisms'' (from the Greek τέλος or ''telos'' for ''end'', ''goal'', or ''purpose'') in machines with ''corrective feedback'' dates from as far back as the late 18th century when James Watt's steam engine was equipped with a governor, a centrifugal feedback valve for controlling the speed of the engine. Alfred Russel Wallace identified this as the principle of evolution in his famous 1858 paper. In 1868 James Clerk Maxwell published a theoretical article on governors, one of the first to discuss and refine the principles of self-regulating devices. Jakob von Uexküll applied the feedback mechanism via his model of functional cycle (''Funktionskreis'') in order to explain animal behaviour and the origins of meaning in general.
Contemporary cybernetics began as an interdisciplinary study connecting the fields of control systems,
electrical network theory,
mechanical engineering,
logic modeling,
evolutionary biology and
neuroscience in the 1940s. Electronic control systems originated with the 1927 work of
Bell Telephone Laboratories engineer
Harold S. Black on using negative feedback to control amplifiers. The ideas are also related to the biological work of
Ludwig von Bertalanffy in General Systems Theory.
Early applications of negative feedback in electronic circuits included the control of gun mounts and radar antenna during World War II. Jay Forrester, a graduate student at the Servomechanisms Laboratory at MIT during WWII working with Gordon S. Brown to develop electronic control systems for the U.S. Navy, later applied these ideas to social organizations such as corporations and cities as an original organizer of the MIT School of Industrial Management at the MIT Sloan School of Management. Forrester is known as the founder of System Dynamics.
W. Edwards Deming, the Total Quality Management guru for whom Japan named its top post-WWII industrial prize, was an intern at Bell Telephone Labs in 1927 and may have been influenced by network theory. Deming made "Understanding Systems" one of the four pillars of what he described as "Profound Knowledge" in his book "The New Economics."
Numerous papers spearheaded the coalescing of the field. In 1935 Russian physiologist P.K. Anokhin published a book in which the concept of feedback ("back afferentation") was studied. The study and mathematical modelling of regulatory processes became a continuing research effort and two key articles were published in 1943. These papers were "Behavior, Purpose and Teleology" by Arturo Rosenblueth, Norbert Wiener, and Julian Bigelow; and the paper "A Logical Calculus of the Ideas Immanent in Nervous Activity" by Warren McCulloch and Walter Pitts.
Cybernetics as a discipline was firmly established by Wiener, McCulloch and others, such as W. Ross Ashby and W. Grey Walter. Walter was one of the first to build autonomous robots as an aid to the study of animal behaviour. Together with the US and UK, an important geographical locus of early cybernetics was France.
In the spring of 1947, Wiener was invited to a congress on harmonic analysis, held in Nancy, France. The event was organized by the Bourbaki, a French scientific society, and mathematician Szolem Mandelbrojt (1899–1983), uncle of the world-famous mathematician Benoît Mandelbrot.
During this stay in France, Wiener received the offer to write a manuscript on the unifying character of this part of applied mathematics, which is found in the study of Brownian motion and in telecommunication engineering. The following summer, back in the United States, Wiener decided to introduce the neologism cybernetics into his scientific theory. The name ''cybernetics'' was coined to denote the study of "teleological mechanisms" and was popularized through his book ''Cybernetics, or Control and Communication in the Animal and Machine'' (Hermann & Cie, Paris, 1948). In the UK this became the focus for the Ratio Club.
In the early 1940s John von Neumann, although better known for his work in mathematics and computer science, did contribute a unique and unusual addition to the world of cybernetics: Von Neumann cellular automata, and their logical follow up the Von Neumann Universal Constructor. The result of these deceptively simple thought-experiments was the concept of self replication which cybernetics adopted as a core concept. The concept that the same properties of genetic reproduction applied to social memes, living cells, and even computer viruses is further proof of the somewhat surprising universality of cybernetic study.
Wiener popularized the social implications of cybernetics, drawing analogies between automatic systems (such as a regulated steam engine) and human institutions in his best-selling ''The Human Use of Human Beings : Cybernetics and Society'' (Houghton-Mifflin, 1950).
While not the only instance of a research organization focused on cybernetics, the Biological Computer Lab at the University of Illinois, Urbana/Champaign, under the direction of Heinz von Foerster, was a major center of cybernetic research for almost 20 years, beginning in 1958.
In the 1970s,
new cyberneticians emerged in multiple fields, but especially in
biology. The ideas of
Maturana,
Varela and
Atlan, according to
Dupuy (1986) "realized that the cybernetic metaphors of the program upon which molecular biology had been based rendered a conception of the autonomy of the living being impossible. Consequently, these thinkers were led to invent a new cybernetics, one more suited to the organizations which mankind discovers in nature - organizations he has not himself invented". However, during the 1980s the question of whether the features of this new cybernetics could be applied to social forms of organization remained open to debate.
In political science, Project Cybersyn attempted to introduce a cybernetically controlled economy during the early 1970s. In the 1980s, according to Harries-Jones (1988) "unlike its predecessor, the new cybernetics concerns itself with the interaction of autonomous political actors and subgroups, and the practical and reflexive consciousness of the subjects who produce and reproduce the structure of a political community. A dominant consideration is that of recursiveness, or self-reference of political action both with regards to the expression of political consciousness and with the ways in which systems build upon themselves".
One characteristic of the emerging new cybernetics considered in that time by Geyer and van der Zouwen, according to Bailey (1994), was "that it views information as constructed and reconstructed by an individual interacting with the environment. This provides an epistemological foundation of science, by viewing it as observer-dependent. Another characteristic of the new cybernetics is its contribution towards bridging the "micro-macro gap". That is, it links the individual with the society". Another characteristic noted was the "transition from classical cybernetics to the new cybernetics [that] involves a transition from classical problems to new problems. These shifts in thinking involve, among others, (a) a change from emphasis on the system being steered to the system doing the steering, and the factor which guides the steering decisions.; and (b) new emphasis on communication between several systems which are trying to steer each other". The work of Gregory Bateson was also strongly influenced by cybernetics.
Recent endeavors into the true focus of cybernetics, systems of control and emergent behavior, by such related fields as game theory (the analysis of group interaction), systems of feedback in evolution, and metamaterials (the study of materials with properties beyond the Newtonian properties of their constituent atoms), have led to a revived interest in this increasingly relevant field.
Cybernetics is an earlier but still-used generic term for many types of subject matter. These subjects also extend into many others areas of science, but are united in their study of control of systems.

Cybernetics in biology is the study of cybernetic systems present in biological organisms, primarily focusing on how animals adapt to their environment, and how information in the form of
genes is passed from generation to generation. There is also a secondary focus on
combining artificial systems with biological systems.

By examining group behavior through the lens of cybernetics, sociologists can seek the reasons for such spontaneous events as
smart mobs and
riots, as well as how communities develop rules such as etiquette by consensus without formal discussion.
Affect Control Theory explains
role behavior,
emotions, and
labeling theory in terms of homeostatic maintenance of sentiments associated with cultural categories. The most comprehensive attempt ever made in the social sciences to increase cybernetics in a generalized theory of society was made by
Talcott Parsons. In this way, cybernetics establishes the basic hierarchy in Parsons'
AGIL paradigm, which is the ordering system-dimension of his
action theory. These and other cybernetic models in sociology are reviewed in a book edited by McClelland and Fararo.

Nicolas Schöffer's ''CYSP I'' (1956) was perhaps the first artwork to explicitly employ cybernetic principles (CYSP is an acronym that joins the first two letters of the words "CYbernetic" and "SPatiodynamic"). The artist
Roy Ascott elaborated an extensive theory of cybernetic art in "Behaviourist Art and the Cybernetic Vision" (Cybernetica, Journal of the International Association for Cybernetics (Namur), Volume IX, No.4, 1966; Volume X No.1, 1967) and in "The Cybernetic Stance: My Process and Purpose" (Leonardo Vol 1, No 2, 1968). Art historian
Edward A. Shanken has written about the history of art and cybernetics in essays including "
Cybernetics and Art: Cultural Convergence in the 1960s" and "From Cybernetics to Telematics: The Art, Pedagogy, and Theory of Roy Ascott"(2003), which traces the trajectory of Ascott's work from cybernetic art to
telematic art (art using computer networking as its medium, a precursor to
net.art.)
