Psychologists From England

"If intellectual power is to be developed, we must somehow construct amplifiers for intelligence — devices that, supplied with a little intelligence, will emit a lot."

"Two main lines are readily distinguished. One already well developed in the hands of von Bertalanffy and his co-workers, takes the world as we find it, examines the various systems that occur in it - zoological, physiological, and so on - and then draws up statements about the regularities that have been observed to hold. This method is essentially empirical. The second method is to start at the other end. Instead of studying first one system, then a second, then a third, and so on, it goes to the other extreme, considers the set of all conceivable systems and then reduces the set to a more reasonable size. This is the method I have recently followed."

"Every isolated determinate dynamic system, obeying unchanging laws, will ultimately develop some sort of organisms that are adapted to their environments."

"Every stable system has the property that if displaced from a state of equilibrium and released, the subsequent movement is so matched to the initial displacement that the system is brought back to the state of equilibrium. A variety of disturbances will therefore evoke a variety of matched reactions."

"Many workers in the biological sciences — physiologists, psychologists, sociologists — are interested in cybernetics and would like to apply its methods and techniques to their own specialty. Many have, however, been prevented from taking up the subject by an impression that its use must be preceded by a long study of electronics and advanced pure mathematics; for they have formed the impression that cybernetics and these subjects are inseparable. The author is convinced, however, that this impression is false. The basic ideas of cybernetics can be treated without reference to electronics, and they are fundamentally simple; so although advanced techniques may be necessary for advanced applications, a great deal can be done, especially in the biological sciences, by the use of quite simple techniques, provided they are used with a clear and deep understanding of the principles involved. It is the author’s belief that if the subject is founded in the common-place and well understood, and is then built up carefully, step by step, there is no reason why the worker with only elementary mathematical knowledge should not achieve a complete understanding of its basic principles. With such an understanding he will then be able to see exactly what further techniques he will have to learn if he is to proceed further; and, what is particularly useful, he will be able to see what techniques he can safely ignore as being irrelevant to his purpose."

"Cybernetics was defined by Wiener as “the science of control and communication, in the animal and the machine” — in a word, as the art of steermanship, and it is to this aspect that the book will be addressed. Co-ordination, regulation and control will be its themes, for these are of the greatest biological and practical interest. We must, therefore, make a study of mechanism; but some introduction is advisable, for cybernetics treats the subject from a new, and therefore unusual, angle... The new point of view should be clearly understood, for any unconscious vacillation between the old and the new is apt to lead to confusion."

"Cybernetics treats not things but ways of behaving. It does not ask “what is this thing?” but “what does it do?”... It is thus essentially functional and behaviouristic. Cybernetics deals with all forms of behavior in so far as they are regular, or determinate, or reproducible. The materiality is irrelevant... The truths of cybernetics are not conditional on their being derived from some other branch of science. Cybernetics has its own foundations."

"Cybernetics is likely to reveal a great number of interesting and suggestive parallelisms between machine and brain and society. And it can provide the common language by which discoveries in one branch can readily be made use of in the others... [There are] two peculiar scientific virtues of cybernetics that are worth explicit mention. One is that it offers a single vocabulary and a single set of concepts suitable for representing the most diverse types of system... The second peculiar virtue of cybernetics is that it offers a method for the scientific treatment of the system in which complexity is outstanding and too important to be ignored. Such systems are, as we well know, only too common in the biological world!"

"The most fundamental concept in cybernetics is that of "difference", either that two things are recognisably different or that one thing has changed with time. Its range of application need not be described now, for the subsequent chapters will illustrate the range abundantly. All the changes that may occur with time are naturally included, for when plants grow and planets age and machines move some change from one state to another is implicit. So our first task will be to develop this concept of "change", not only making it more precise but making it richer, converting it to a form that experience has shown to be necessary if significant developments are to be made."

"By a state of a system is meant any well-defined condition or property that can be recognised if it occurs again. Every system will naturally have many possible states."

"[T]he concept of “”, so simple and natural in certain elementary cases, becomes artificial and of little use when the interconnexions between the parts become more complex. When there are only two parts joined so that each affects the other, the properties of the feedback give important and useful information about the properties of the whole. But when the parts rise to even as few as four, if every one affects the other three, then twenty circuits can be traced through them; and knowing the properties of all the twenty circuits does not give complete information about the system. Such complex systems cannot be treated as an interlaced set of more or less independent feedback circuits, but only as a whole. For understanding the general principles of dynamic systems, therefore, the concept of feedback is inadequate in itself. What is important is that complex systems, richly cross-connected internally, have complex behaviours, and that these behaviours can be goal-seeking in complex patterns."

"As shorthand, when the phenomena are suitably simple, words such as equilibrium and stability are of great value and convenience. Nevertheless, it should be always borne in mind that they are mere shorthand, and that the phenomena will not always have the simplicity that these words presuppose."

"There comes a stage, however, as the system becomes larger and larger, when the reception of all the information is impossible by reason of its sheer bulk. Either the recording channels cannot carry all the information, or the observer, presented with it all, is overwhelmed. When this occurs, what is he to do? The answer is clear: he must give up any ambition to know the whole system. His aim must be to achieve a partial knowledge that, though partial over the whole, is none the less complete within itself, and is sufficient for his ultimate practical purpose"

"The fundamental questions in regulation and control can be answered only when we are able to consider the broader set of what it might do, when “might” is given some exact specification."

"[Constraint] is a relation between two sets, and occurs when the variety that exists under one condition is less than the variety that exists under another."

"When a constraint exists advantage can usually be taken of it."

"Further, as every law of nature implies the existence of an invariant, it follows that every law of nature is a constraint."

"The concept of "variety" [is] inseparable from that of "information.""

"The most basic facts in biology are that this earth is now two thousand million years old, and that the biologist studies mostly that which exists today."

"Variety can destroy variety."

"Its importance is that if R[egulator] is fixed in its channel capacity, the law places an absolute limit to the amount of regulation (or control) that can be achieved by R, no matter how R is re-arranged internally, or how great the opportunity in T. Thus the ecologist, if his capacity as a channel is unchangeable, may be able at best only to achieve a fraction of what he would like to do. This fraction may be disposed in various ways —he may decide to control outbreaks rather than extensions, or virus infections rather than bacillary — but the quantity of control that he can exert is still bounded. So too the economist may have to decide to what aspect he shall devote his powers, and the psychotherapist may have to decide what symptoms shall be neglected and what controlled."

"Throughout, we shall be exemplifying the thesis of D. M. MacKay: that quantity of information, as measured here, always corresponds to some quantity, i.e. intensity, of selection, either actual or imaginable"

"Duration of selection. At this point a word should be said about how long a given act of selection may take, for when actual cases are examined, the time taken may, at first estimate, seem too long for any practical achievement. The question becomes specially important when the regulator is to be developed for regulation of a very large system. Approximate calculation of the amount of selection likely to be necessary may suggest that it will take a time far surpassing the cosmological; and one may jump to the conclusion that the time taken in actually achieving the selection would have to be equally long. This is far from being the case, however."

"General systems theory is considered as a formal theory (Mesarovic, Wymore), a methodology (Ashby, Klir), a way of thinking (Bertalanffy, Churchman), a way of looking at the world (Weinberg), a search for an optimal simplification (Ashby, Weinberg), didactic method (Boulding, Klir, Weinberg), metalanguage (Logren), and profession (Klir)."

"W. Ross Ashby is one of the founding fathers of both cybernetics and systems theory. He developed such fundamental ideas as the homeostat, the law of requisite variety, the principle of self-organization, and the principle of regulatory models."

"The brilliant British psychiatrist, neuroscientist, and mathematician Ross Ashby was one of the pioneers in early and mid-phase cybernetics and thereby one of the leading progenitors of modern complexity theory. Not one to take either commonly used terms or popular notions for granted, Ashby probed deeply into the meaning of supposedly self-organizing systems. At the time of the following article, he had been working on a mathematical formalism of his homeostat, a hypothetical machine established on an axiomatic, set theoretical foundation that was supposed to offer a sufficient description of a living organism's learning and adaptive intelligence. Ashby's homeostat had a small number of essential variables serving to maintain its operation over a wide range of environmental conditions so that if the latter changed and thereby shifted the variables beyond the range where the homeostat could safely function, a new 'higher' level of the machine was activated in order to randomly reset the lower level's internal connections or organization... Like the role of random mutations during evolution, if the new range set at random proved functional, the homeostat survived, otherwise it expired..."

"[A] famous photograph... showing McCulloch (1898–1969) and Norbert Wiener (1894–1964) with British Cyberneticians Ross Ashby (1903–1972) and Grey Walter (1910–1977), first appeared in de Latil (1953) with the caption "The four pioneers of Cybernetics get together in Paris", and encapsulates a view of the development of cybernetics that has slowly become more accepted: that there were important British contributions from the outset."

"What is the use of ultra-stable systems which have the property that if you subject them to some influence, they change to an equilibrium state but don't even remember where they were? Warren McCulloch was a great fan of Ashby, and so finally I asked him, "Well, why do you think this is so important?" And he said, "Because he explains it so clearly." I went back and read Design for a Brain again and couldn't but agree with McCulloch that Ashby had managed to explain something more clearly than everyone else put together. The fact that the systems didn't do anything was a little bit disappointing, but that was as nothing compared to the clarity. So, if you want to explain something, you should read Design for a Brain and use that as a model for your next paper."

"We are moving towards another type of society than that to which we have become accustomed. This is sometimes referred to as a new service society, the society of the second industrial revolution or the post-industrial society. There is no guarantee of our safe arrival. Not only are the interdependencies greater – they are differently structured... The changes in the policy field [housing, health care, urban rehabilitation, education, etc.] demand a new mobilization of the sciences."

"Trist both pioneered and embodied action research – an interplay between his deep interaction with real problems in organisations, and the forefront of academic thought in social science. through coal mines in Yorkshire to an entire manufacturing town in New York State – he was an active contributor to both theory and practice. He said that “I used to look with longing at what I called the ‘white-coated peace’, the tranquillity of the white-coated scientists working in the lab. But that was not for me. I didn’t have a white lab coat. I was in the messy, ambiguous, problematic stuff that you have to endure if you are going to be a psychologist”."

"One major figure in the (Tavistock) institute and its chairman for many years was Eric Trist, who is the primary author of sociotechnical systems theory. Trist was joined in his theoretical efforts and in his research by others who were either employed by the institute or strongly influenced by it. Thus in many respects sociotechnical systems theory is a product of the same kind of group interaction on which the theory itself focuses. Trist remains the prime contributor to the theory, even though he left the institute after some twenty years."

"# Macrosocial systems. These include systems in communities and industrial sectors, and institutions operating at the overall level of a society. They constitute what I have called "domains". (Trist, 1976a; 1979a). One may regard media as socio-technical systems. McLuhan (1964) has shown that the technical character of different media has far-reaching effects on users. The same applies to architectural forms and the infrastructure of the built environment. Although these are not organizations, they are socio-technical phenomena. They are media in Heider's (1942) as well as McLuhan's sense."

"# Whole organization systems. At one limit these would be plants or equivalent self-standing workplaces. At the other, they would be entire corporations or public agencies. They persist by maintaining a steady state with their environment."

"# Primary work systems. These are the systems which carry out the set of' activities involved in an identifiable and bounded subsystem of a whole organization - such as a line department or a service unit..."

"Socio-technical studies needed to be carried out at three broad levels - from micro to macro - all of which are interrelated:"

"# It was variety-increasing for both the individual and the organization rather than variety-decreasing in the bureaucratic mode."

"# It treated the individual as complementary to the machine rather than as an extension of it (Jordan, 1963)."

"#This principle valued the discretionary rather than the prescribed part of work roles (Jaques, 1956)."

"# A design principle based on the redundancy of functions rather than on the redundancy of parts (Emery, 1967) characterized the underlying organizational philosophy which tended to develop multiple skills in the individual and immensely increase the response repertoire of the group."

"# Internal regulation of the system by the group was thus rendered possible rather than the external regulation of individuals by supervisors."

"# Correspondingly, the work group became central rather than the individual jobholder."

"# The work system, which comprised a set of activities that made up a functioning whole, now became the basic unit rather than the single jobs into which it was decomposable."

"What happened in the Haighmoor seam gave to Bamforth and myself a first glimpse of the "emergence of a new paradigm of work" (Emery, 1978) in which the best match would be sought between the requirements of the social and technical systems. Some of the principles involved were as follows:"

"The work organization of the new seam was, to us, a novel phenomenon consisting of relatively autonomous groups interchanging roles and shifts and regulating their affairs with a minimum of supervision. Cooperation between task groups was everywhere in evidence, personal commitment obvious, absenteeism low, accidents infrequent, productivity high. The contrast was large between the atmosphere and arrangements on these faces and those in the conventional areas of the pit, where the negative features characteristic of the industry were glaringly apparent. The men told us that in order to adapt with best advantage to the technical conditions in the new seam, they had evolved a form of work organization based on practices common in the unmechanized days when small groups, who took responsibility for the entire cycle, had worked autonomously."

"Fellows were encouraged to revisit their former industries and make a report on any new perceptions they might have. One of these Fellows, Ken Bamforth, returned with news of an innovation in work practice and organization which had occurred in a new seam in the colliery where he used to work in the South Yorkshire coalfield. The seam, the Haighmoor, had become possible to mine "shortwall" because of improved roof control."

"Coal being then the chief source of power, much industrial reconstruction depended on there being a plentiful and cheap supply. But the newly nationalized industry was not doing well. Productivity failed to increase in step with increases in mechanization. Men were leaving the mines in large numbers for more attractive opportunities in the factories. Among those who remained, absenteeism averaged 20 percent. Labor disputes were frequent despite improved conditions of employment. Some time earlier the National Coal Board had asked the Institute to make a comparative study of a high producing, high morale mine and a low producing, low morale, but otherwise equivalent mine."

"The socio-technical concept arose in conjunction with the first of several field projects undertaken by the Tavistock Institute in the coal-mining industry in Britain. The time (1949) was that of the postwar reconstruction of industry in relation to which the Institute had two action research projects.(2) One project was concerned with group relations in depth at all levels (including the management/labor interface) in a single organization - an engineering company in the private sector. The other project focused on the diffusion of innovative work practices and organizational arrangements that did not require major capital expenditure but which gave promise of raising productivity. The former project represented the first comprehensive application in an industrial setting of the socio-clinical ideas concerning groups being developed at the Tavistock."

"Socio-technical analysis is made at three levels - the primary work system; the whole organization; and macrosocial phenomena."

"A main problem in the study of is that the environmental contexts in which organizations exist are themselves changing, at an increasing rate and towards increasing complexity. This point, in itself, scarcely needs laboring. Nevertheless, characteristics of organizational environments demand consideration for their own sake if there is to be an advancement of understanding in the behavioral sciences of a great deal that is taking place under the impact of technological change, especially at the present time."

"Ludwig von Bertalanffy's formulation enables exchange processes between the organism, or organisation, and the elements in its environment to be dealt with in a new perspective, it does not deal at all with those processes in the environment itself which are among the determining conditions of the exchanges. To analyse these an additional concept is needed - the causal texture of the environment."
