Cybernetics is the transdisciplinary study of circular processes such as feedback systems where outputs are also inputs. It is concerned with general principles that are relevant across multiple contexts, [1] including in ecological, technological, economic, biological, cognitive and social systems and also in practical activities such as designing, [2] 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. [3] [4]
Cybernetics' transdisciplinary [5] character has meant that it intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.
Cybernetics has been defined in a variety of ways, reflecting "the richness of its conceptual base." [6] One of the best known definitions is that of the American scientist Norbert Wiener, who characterised cybernetics as concerned with "control and communication in the animal and the machine." [7] 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." [8] 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." [9]
Other definitions include: [10] "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 Ancient Greek term κυβερνητικός (kubernētikos, '(good at) steering') appears in Plato's Republic [11] and Alcibiades , where the metaphor of a steersman is used to signify the governance of people. [12] 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. [7] 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 . [note 1] In the book, Wiener states:
After much consideration, we have come to the conclusion that all the existing terminology has too heavy a bias to one side or another to serve the future development of the field as well as it should; and as happens so often to scientists, we have been forced to coin at least one artificial neo-Greek expression to fill the gap. We have decided to call the entire field of control and communication theory, whether in the machine or in the animal, by the name Cybernetics, which we form from the Greek κυβερνήτης or steersman .
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". [7]
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 Bigelow –based on the research on living organisms that Rosenblueth did in Mexico –and 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 . [7]
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 [14] 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. [15] Similarly, computer science became defined as a distinct academic discipline in the 1950s and early 1960s. [16]
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. [17]
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. [18] 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, [19] [20] and the unrealised Fun Palace project (London, unrealised, 1964 onwards), where Gordon Pask was consultant to architect Cedric Price and theatre director Joan Littlewood. [21]
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". [22] 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 [23] [24] or a "new branch of engineering". [25]
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. [3]
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. [26]
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:
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. [30] In the social and behavioral sciences, cybernetics has included and influenced work in anthropology, sociology, economics, family therapy, [31] cognitive science, and psychology. [32] [33]
As cybernetics has developed, it broadened in scope to include work in management, design, [34] pedagogy, and the creative arts, [35] while also developing exchanges with constructivist philosophies, counter-cultural movements, [36] and media studies. [37] 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, [38] design research, [39] and the development of systemic design and metadesign practices.
Cybernetics is often understood within the context of systems science, systems theory, and systems thinking. [40] [41] 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. [42]
Academic journals with focuses in cybernetics include:
Academic societies primarily concerned with cybernetics or aspects of it include:
Systems theory is the transdisciplinary study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems. A system is "more than the sum of its parts" when it expresses synergy or emergent behavior.
Norbert Wiener 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 later became an early researcher in stochastic and mathematical noise processes, contributing work relevant to electronic engineering, electronic communication, and control systems.
Heinz von Foerster was an Austrian-American scientist combining physics and philosophy, and widely attributed as the originator of second-order cybernetics. He was twice a Guggenheim fellow and also was a fellow of the American Association for the Advancement of Science, 1980. He is well known for his 1960 Doomsday equation formula published in Science predicting future population growth.
Self-organization, also called spontaneous order in the social sciences, is a process where some form of overall order arises from local interactions between parts of an initially disordered system. The process can be spontaneous when sufficient energy is available, not needing control by any external agent. It is often triggered by seemingly random fluctuations, amplified by positive feedback. The resulting organization is wholly decentralized, distributed over all the components of the system. As such, the organization is typically robust and able to survive or self-repair substantial perturbation. Chaos theory discusses self-organization in terms of islands of predictability in a sea of chaotic unpredictability.
William Ross Ashby was an English psychiatrist and a pioneer in cybernetics, the study of the science of communications and automatic control systems in both machines and living things. His first name was not used: he was known as Ross Ashby.
Sociocybernetics is an interdisciplinary science between sociology and general systems theory and cybernetics. The International Sociological Association has a specialist research committee in the area – RC51 – which publishes the (electronic) Journal of Sociocybernetics.
Second-order cybernetics, also known as the cybernetics of cybernetics, is the recursive application of cybernetics to itself and the reflexive practice of cybernetics according to such a critique. It is cybernetics where "the role of the observer is appreciated and acknowledged rather than disguised, as had become traditional in western science". Second-order cybernetics was developed between the late 1960s and mid 1970s by Heinz von Foerster and others, with key inspiration coming from Margaret Mead. Foerster referred to it as "the control of control and the communication of communication" and differentiated first-order cybernetics as "the cybernetics of observed systems" and second-order cybernetics as "the cybernetics of observing systems".
Biocybernetics is the application of cybernetics to biological science disciplines such as neurology and multicellular systems. Biocybernetics plays a major role in systems biology, seeking to integrate different levels of information to understand how biological systems function. The field of cybernetics itself has origins in biological disciplines such as neurophysiology. Biocybernetics is an abstract science and is a fundamental part of theoretical biology, based upon the principles of systemics. Biocybernetics is a psychological study that aims to understand how the human body functions as a biological system and performs complex mental functions like thought processing, motion, and maintaining homeostasis.(PsychologyDictionary.org)Within this field, many distinct qualities allow for different distinctions within the cybernetic groups such as humans and insects such as beehives and ants. Humans work together but they also have individual thoughts that allow them to act on their own, while worker bees follow the commands of the queen bee. . Although humans often work together, they can also separate from the group and think for themselves.(Gackenbach, J. 2007) A unique example of this within the human sector of biocybernetics would be in society during the colonization period, when Great Britain established their colonies in North America and Australia. Many of the traits and qualities of the mother country were inherited by the colonies, as well as niche qualities that were unique to them based on their areas like language and personality—similar vines and grasses, where the parent plant produces offshoots, spreading from the core. Once the shoots grow their roots and get separated from the mother plant, they will survive independently and be considered their plant. Society is more closely related to plants than to animals since, like plants, there is no distinct separation between parent and offspring. The branching of society is more similar to plant reproduction than to animal reproduction. Humans are a k- selected species that typically have fewer offspring that they nurture for longer periods than r -selected species. It could be argued that when Britain created colonies in regions like North America and Australia, these colonies, once they became independent, should be seen as offspring of British society. Like all children, the colonies inherited many characteristics, such as language, customs and technologies, from their parents, but still developed their own personality. This form of reproduction is most similar to the type of vegetative reproduction used by many plants, such as vines and grasses, where the parent plant produces offshoots, spreading ever further from the core. When such a shoot, once it has produced its own roots, gets separated from the mother plant, it will survive independently and define a new plant. Thus, the growth of society is more like that of plants than like that of the higher animals that we are most familiar with, there is not a clear distinction between a parent and its offspring. Superorganisms are also capable of the so-called "distributed intelligence," a system composed of individual agents with limited intelligence and information. These can pool resources to complete goals beyond the individuals' reach on their own. Similar to the concept of "Game theory." In this concept, individuals and organisms make choices based on the behaviors of the other player to deem the most profitable outcome for them as an individual rather than a group.
Andrew Gordon Speedie Pask was a British cybernetician, inventor and polymath who made multiple contributions to cybernetics, educational psychology, educational technology, applied epistemology, chemical computing, architecture, and systems art. During his life, he gained three doctorate degrees. He was an avid writer, with more than two hundred and fifty publications which included a variety of journal articles, books, periodicals, patents, and technical reports. He worked as an academic and researcher for a variety of educational settings, research institutes, and private stakeholders including but not limited to the University of Illinois, Concordia University, the Open University, Brunel University and the Architectural Association School of Architecture. He is known for the development of conversation theory.
The Macy conferences were a set of meetings of scholars from various academic disciplines held in New York under the direction of Frank Fremont-Smith at the Josiah Macy Jr. Foundation starting in 1941 and ending in 1960. The explicit aim of the conferences was to promote meaningful communication across scientific disciplines, and restore unity to science. There were different sets of conferences designed to cover specific topics, for a total of 160 conferences over the 19 years this program was active; the phrase "Macy conference" does not apply only to those on cybernetics, although it is sometimes used that way informally by those familiar only with that set of events. Disciplinary isolation within medicine was viewed as particularly problematic by the Macy Foundation, and given that their mandate was to aid medical research, they decided to do something about it. Thus other topics covered in different sets of conferences included: aging, adrenal cortex, biological antioxidants, blood clotting, blood pressure, connective tissues, infancy and childhood, liver injury, metabolic interrelations, nerve impulse, problems of consciousness, and renal function.
Ranulph Glanville was an Anglo-Irish cybernetician and design theorist. He was a founding vice-president of the International Academy for Systems and Cybernetic Sciences (2006–2009) and president of the American Society for Cybernetics (2009–2014).
Management cybernetics is concerned with the application of cybernetics to management and organizations. "Management cybernetics" was first introduced by Stafford Beer in the late 1950s and introduces the various mechanisms of self-regulation applied by and to organizational settings, as seen through a cybernetics perspective. Beer developed the theory through a combination of practical applications and a series of influential books. The practical applications involved steel production, publishing and operations research in a large variety of different industries. Some consider that the full flowering of management cybernetics is represented in Beer's books. However, learning continues.
Stuart Anspach Umpleby is an American cybernetician and professor in the Department of Management and Director of the Research Program in Social and Organizational Learning in the School of Business at the George Washington University.
Peter Andrew Corning is an American biologist, consultant, and complex systems scientist, Director of the Institute for the Study of Complex Systems, in Seattle, Washington. He is known especially for his work on the causal role of synergy in evolution.
Pharmacocybernetics is an upcoming field that describes the science of supporting drugs and medications use through the application and evaluation of informatics and internet technologies, so as to improve the pharmaceutical care of patients. It is an interdisciplinary field that integrates the domains of medicine and pharmacy, computer sciences and psychological sciences to design, develop, apply and evaluate technological innovations which improve drugs and medications management, as well as prevent or solve drug-related problems.
Cybernetics: Or Control and Communication in the Animal and the Machine is a book written by Norbert Wiener and published in 1948. It is the first public usage of the term "cybernetics" to refer to self-regulating mechanisms. The book laid the theoretical foundation for servomechanisms, automatic navigation, analog computing, artificial intelligence, neuroscience, and reliable communications.
Self-organization, a process where some form of overall order arises out of the local interactions between parts of an initially disordered system, was discovered in cybernetics by William Ross Ashby in 1947. It states that any deterministic dynamic system automatically evolves towards a state of equilibrium that can be described in terms of an attractor in a basin of surrounding states. Once there, the further evolution of the system is constrained to remain in the attractor. This constraint implies a form of mutual dependency or coordination between its constituent components or subsystems. In Ashby's terms, each subsystem has adapted to the environment formed by all other subsystems.
Laurence Dale Richards has been a key figure in the modern development of cybernetics as a transdisciplinary field of inquiry, often referred to as the new cybernetics. He was the first to create interdisciplinary masters and doctoral programs in engineering management, with curricula built explicitly on concepts drawn from systems theory and cybernetics. He served as president for both the American Society for Cybernetics (1986–88) and the American Society for Engineering Management (1998–99) and was elected an Academician in the International Academy for Systems and Cybernetic Sciences in 2010.
Dualism in cybernetics refers to systems or problems in which one or more intelligent adversaries attempt to exploit the weaknesses of the investigator. Examples could include a game-playing opponent, adversarial law, evolutionary systems of predator/parasite and prey/host, or politics/enslavement attempts.
It seems that cybernetics is many different things to many different people. But this is because of the richness of its conceptual base; and I believe that this is very good, otherwise cybernetics would become a somewhat boring exercise. However, all of those perspectives arise from one central theme; that of circularity
artificial intelligence was born at a conference at Dartmouth in 1956 that was organized by McCarthy, Minsky, rochester, and shannon, three years after the Macy conferences on cybernetics had ended (Boden 2006; McCorduck 1972). The two movements coexisted for roughly a de- cade, but by the mid-1960s, the proponents of symbolic ai gained control of national funding conduits and ruthlessly defunded cybernetics research. This effectively liquidated the subfields of self-organizing systems, neural networks and adaptive machines, evolutionary programming, biological computation, and bionics for several decades, leaving the workers in management, therapy and the social sciences to carry the torch. i think some of the polemical pushing-and-shoving between first-order control theorists and second-order crowds that i witnessed in subsequent decades was the cumulative result of a shift of funding, membership, and research from the "hard" natural sciences to "soft" socio-psychological interventions.
