The Tragedy of the Tragedy of the Commons

The man who wrote one of environmentalism’s most-cited essays was a racist, eugenicist, nativist and Islamaphobe—plus his argument was wrong

Fifty years ago, University of California professor Garrett Hardin penned an influential essay in the journal Science. Hardin saw all humans as selfish herders: we worry that our neighbors’ cattle will graze the best grass. So, we send more of our cows out to consume that grass first. We take it first, before someone else steals our share. This creates a vicious cycle of environmental degradation that Hardin described as the “tragedy of the commons.”

Twenty years of global biosphere data visualization by NASA.

As our ecologic crisis deepens, art can provide the unique insights necessary to light our path forward. This Fall, the artists in Gray Area’s Experiential Space Research Lab have been exploring this potential of immersive art as a tool for understanding. Our call for participation, Reworlding: The Art of Living Systemsinvited artists with diverse backgrounds to develop novel experiences for thinking like a living planet. Since the first meeting in August, the artists have been developing an immersive exhibition to reveal intimate entanglements amongst Earth’s living forms — and how to make the planetary personal.

With the support of the Knight Foundation, Gray Area has been collaborating with Gaian Systems, a collaboration between the design studio Spherical and literature and science scholar Bruce Clarke, the 2018–2019 Blumberg/NASA Chair in Astrobiology at the Library of Congress. This post introduces the broader context of these explorations in Earth Systems Science for the Research Lab.


Planetary Science & The Rise Of Cybernetic Art

The most unexpected discovery of the Space Age is that Earth is alive. Far from being a cosmic backwater or a passive vessel for random organisms, it is the matrix and dynamic extension of all life as we know it. Over several billion years, living systems have transformed and regulated Earth’s planetary environment. From oxygenating the global atmosphere to lubricating the tectonic plates to myceliating the soils, living systems have bent the planet to their own needs. Now, under the influence of human technologies, this reshaping continues at a rapidly accelerated pace.

Hierarchy, teams, self-organisation, levels of learning, circularity, domination, and accountability – six articles from Georges Romme (and reflections on Requisite Agility)

I’m participating in a thing organised by Amit Arora called Requisite Agility – a sort of project, a sort of movement, which began with Amit producing some software for someone doing Requisite Organisation work (after Elliott Jaques). With the title Requisite Organisation, some people persuaded of the deep value of the underlying insights of management cybernetics said ‘hang on, we know about this stuff’, and therefore the movement has become about how we can bring together a meta perspective on RO, Agile, and the viable systems model etc – along with a lot of other stuff people work with. As you can imagine, this is a bit like herding cats to the power of x, and there are a few fundamental challenges here:
  • are we seeking an underlying theoretical/insight-based approach from which the most powerful organisational interventions can be derived, or an effective collation of multiple methodologies from which to select? (personally, I’d say the former, with the latter in its service)
  • are we integrating ‘Requisite’ (i.e. Requisite Organisation) with ‘Agility’ (i.e. the Agile movement), or looking for approaches that can effectively target approaches that help organisations to have a level of operational and strategy agility requisite to their context? (I’d say the latter)
  • are we dealing with two or more incommensurable paradigms here, or apparently opposite ways to achieve the same requisite organisational conditions? (I say the latter)
  • can we overcome our egos, tribalism, and attachment to our approaches – and all the other challenges of bringing together people with a tendency to critical thinking, a need to sell their approaches for their livelihoods, potentially post-conventional thinking, potential to collaborate or compete for work, pressures on our time and capacity, unclear shared goals, different orientations and different emotional biases, etc? (So far, maybe…)
The results of this are as yet not certain, but some signs are promising, and I feel a strong need to be involved because it matches my preoccupations so closely – and the development of my own somewhat-integrated, multi-methodological approach (see https://medium.com/@antlerboy/seeking-a-small-cohort-of-people-to-co-learn-the-redquadrant-way-tool-shed-293a8489e0d5).
I’ve just returned from a two-day ‘bootcamp’ hashing out some of this with a really great group of people (in my experience, always one of the benefits of this kind of work). In particular, we were lucky enough to have with us, on one day only, Professor Georges Romme – https://en.wikipedia.org/wiki/Georges_Romme. Looking into his work, the nuanced understanding he has of organising in complexity, the play-off of ‘hierarchy’ and ‘self-organisation’, learning, and related issues, is really exciting. Hence this selection of some of the most powerful pieces I’ve seen so far.
The Role of Hierarchy in Self-Organizing Systems (April 1995)
This paper discusses the role of hierarchy in human systems. Two kinds of self-organizing processes are distinguished: conservative and dissipative self-organization. The former leads to rather stable and specialistic systems, whereas the latter leads to continuously changing generalistic systems. When conservative and dissipative self-organization are combined, autonomous self-organization emerges. Autonomous self-organization, characterized by intertemporal stability, appears to be fundamental to human organizations. In the context of autonomous self-organization, the traditional concept of hierarchy as a chain of command is replaced by hierarchy as a vertical sequence based on different degrees of abstraction. Moreover, a simple model shows that autonomous self-organization requires large human systems to use a variety of information processing systems, including administrative hierarchy. The model suggests hierarchy is one instrument for variety reduction among several others.

The Role of Hierarchy in Self-Organizing Systems

A Note on the Hierarchy-Team Debate (May 1996)
This note explores the debate between proponents of organizational learning who have criticized hierarchy as an obstacle to learning and those who have defended hierarchy as indispensable for large organizations. By considering hierarchy and team as ideal-typical information systems, it is argued that both teams and hierarchies are essential for organizational learning in large organizations. Teams appear to be the key learning units which are indispensable for producing and understanding novel information, and hierarchies are indispensable for processing and storing important learning results. The trade-off between teams and hierarchy can be solved by emphasizing the idea of circularity, involving the ability to switch between teams and hierarchies as complementary information systems in the context of organizational learning.

A Note on the Hierarchy-Team Debate

Organizational Learning, Circularity and Double-Linking (June 1997) 
In recent writings on organizational learning an interesting debate between proponents of team learning and those defending hierarchy as an essential condition for learning has developed. Here it is argued that teams appear to be the key learning units in organizations, but hierarchies are necessary to store and accumulate important learning results. Thus, in larger organizations teams must be integrated into some kind of hierarchy. Several authors have dealt with the problem of combining the benefits of both hierarchical and team-like structures. Attempts by Likert and Ackoff to combine the benefits of both hierarchical and team structures are based on the ideas of circularity and the (single) linking pin. A further elaboration of these solutions involves the idea of double-linking, as it is used in several Dutch organizations. Double-linking between teams provides the kind of vertical linkages which support and safeguard upward as well as downward information processing. As such, through the principle of double-linking organizations may become reflexive learning organizations.

Organizational Learning, Circularity and Double-Linking

Circular organizing and triple loop learning (June 1999)
The organizational learning literature distinguishes different levels of learning (zero learning and single, double and triple loop learning) in order to understand the complexity and dynamics of changes in policies, objectives, mental maps, and structures and strategies for learning. This article explores the case of an emerging new organizational design, the circular organization, in order to understand the role of triple loop learning. The circular model was developed on the basis of ideas about the relationship between organizational structure and behavior taken from theories of dynamic systems. Circular design precepts appear to provide a structural facilitation of single and double loop learning. In this respect, the circular design tends to act as a facilitating infrastructure for triple loop learning, that is, exploring the structural opportunities and key competences people need to participate in making well-informed choices about policies, objectives and other issues.

Circular organizing and triple loop learning

Domination, Self-Determination and Circular Organizing (September 1999)
The emergence of self-organizing forms of control, based on the idea of self-determination, have challenged traditional forms of control based on the concept of domination. As such, self-determination has been put forward as an alternative rather than as a complement to domination. This paper describes and explores the circular forms of organizing that have been emerging in several parts of the world, viewing them as a possible synthesis of two existing archetypical concepts of power-self-determination and domination. In particular, the emergence of circular organizing in the Dutch company Endenburg Elektrotechniek is documented and interpreted. This case illustrates how a circular structure can be superimposed on the administrative hierarchy, with the latter continuing to play a substantial role in controlling and managing work processes. In the absence of a single ultimate authority, organizational control is exercised through feedback rather than power. As a result of this study, circularity of power is shown to be an interesting theoretical and instrumental concept.

Domination, Self-Determination and Circular Organizing

Climbing up and down the hierarchy of accountability: Implications for organization design (November 2019)
The notion of organizational hierarchy is disputed, also in view of the rise of new organizational forms claimed to have ‘hierarchies without bosses’. To better understand the contested nature of hierarchy, this essay provides a systemic perspective on organizational hierarchy defined as a sequence, or ladder, of accountability levels. I then argue this ladder can be used in a top-down manner (e.g., as a chain of command), but also in bottom-up ways (e.g., by employees taking charge of higher-level responsibilities). Subsequently, several propositions that may guide future work in this area are formulated and the implications for organization design are fleshed out. Overall, the notion of hierarchy may become less contested by defining it as an accountability ladder which can be instantiated and used in highly different ways.

EXECUTIVE SUMMARY

Stern Stewart Research // Volume 68

We do not just want to keep up, we want to win. Win against the established competition and against start-ups and the Valley. We want to increase decision speed. Silo thinking and traditional hierarchies drive us crazy. Cost-efficiency remains on the agenda and we consistently apply new, digital technologies. We have to get employees convinced and offer them new development paths. The megatrend digitalization and our VUCA world demand a fundamental rethinking of the organization of a company.

But how to do it? We should begin to transform our entire company into a Next Generation Corporation (NextGenCorp). This is an organization consisting of a platform, project swarm and a radically new plexus. We believe both together are possible: flexibility and entrepreneurial freedom while at the same time realizing best practices and scaling economies.

We first separate the platform and the project swarm and then align both towards a common goal in the entrepreneurial plexus. We organize the platform by processes and digitalize it proactively. We eliminate bureaucracy and hierarchies through a swarm of projects. We give the entrepreneurs in the company the freedom to use the platform and mandate the swarm. We believe in a revolutionary and holistic target picture and a flexible roadmap for implementation.

Cybernetic Creature Timeline from cyberneticzoo.com

A timeline showing significant Cybernetic animals and events, the dates being the creation or announcement of the cybernetic models.

[There’s significant confusion between ‘cybernetics’ the set of thinking and theories and insights, all around purposeful or goal-seeking activity in complexity, and robotics – and that is because they came from the same roots. This collection of robots or ‘cybernetic creatures’ covers the range from slightly gimmicky to deeply fascinating (and demonstrates swarming and ‘collective sensemaking’ behaviour long before swarms and boids), but they all use feedback loops to make sense of an unknown, unknowable, and irreducibly complex world in pursuit of a goal – and of course, in so doing, demonstrate the cybernetic roots of agent-based modelling. Of course, everything is so deeply intertwingled that this ought no longer to be surprising to me. I just bought and read RM Currie’s classic ‘work study’ from 1960, the historical section of which draws links (and divergences) between Robert Owen, Perronet, Babbage, FW Taylor, Adam Smith, , the Gilbreths, Bedaux, Cripps, TWI, and thereby between work study, the invention of computing, the human potential movement, capitalism, lean, and this stuff…]

Abstract
Although the strategic ideas of John Boyd encompass much more than the well known OODA loop, the loop does provide a concise framework for improving competitive power throughout an organization. Much of this power will be lost, however, if people use the most common version. Fortunately, Boyd only drew one sketch of the OODA loop, which bears little resemblance to the popular misconception, and that one is
the key to his entire body of work.

Braess’s paradox – Wikipedia

Braess’s paradox

From Wikipedia, the free encyclopedia

Braess’ paradox is the observation that adding one or more roads to a road network can end up impeding overall traffic flow through it. The paradox was postulated in 1968 by German mathematician Dietrich Braess, who noticed that adding a road to a particular congested road traffic network would increase overall journey time.

The paradox may have analogies in electrical power grids and biological systems. It has been suggested that in theory, the improvement of a malfunctioning network could be accomplished by removing certain parts of it. The paradox has been used to explain instances of improved traffic flow when existing major roads are closed

ISSS 2020 conference South Africa July 11-14 2020 – potential for international ‘nodes’ to join in

copy of a message from Peter Tuddenham, past-president@myisss.org:

The ISSS 2020 Conference and Annual Meeting will be held in South Africa July 11-14 2020. The theme is Systemic Change towards Sustainable Development: Innovative and Integrative Approaches The ISSS2020 conference will be co-hosted by the CST and NWU in Stellenbosch, Cape Town, South Africa. Watch the invitational video here https://youtu.be/xLvN-y5Y0Pw

It is understood that not all members will be able to travel to South Africa. It is also recognized that the ISSS now has 9 months of experience conducting SIG sessions on the web using video meeting apps like Bluejeans and Zoom.

I am leading a small sub-committee exploring the possibility of arranging Conference Nodes, so that members not able to travel to South Africa could travel to a location acting a Conference Node somewhere in the world. This ISSS Conference Nodes would mirror some of the main activities at the conference in South Africa but at a location that might be more convenient for members. For example plenary sessions would be live streamed and or recorded and forwarded for viewing, and paper presentations would be organized in both South Africa and at Conference Nodes. I and others helped several members make presentations in their SIG this year from locations around the world to a screen in Corvallis by using bluejeans, zoom, or skype. Presenters paid the full or a day registration fee. Attendees at a Node Conference would be expected to pay a registration fee.

I have taken a look at current membership and looked at countries and regions that have more than 5 members. I think that is a reasonable criteria for an expectation of where an ISSS 2020 Conference Node might be a possibility. The idea is that a Node would encourage face to face activity at the Node and also between the Node and the main conference site in South Africa, and other Nodes too.

Those potential areas are: Argentina, Australia, Canada, Germany, Japan, Korea, Mexico, New Zealand, Uk, and in the USA the states of California, New York, Maryland, Oregon, Virginia and Washington.

To even begin to think of this as a possibility someone or someones in a region would need to step forward and be a Node organizer. If you are willing to think about the possibility please email me. There is no budget for this, and it would be a bootstrap experience.

Obviously the tradition has been to encourage the one site face to face meeting in one location. But we believe we need to be creative to encourage diversity and wider participation and to build membership by developing a Conference Node strategy. There are organizational, technical, financial, and many other challenges to realize this idea.

So if you are willing to explore this idea and willing to organize a Conference Node contact me. This is a possibility exploration at this stage.

Thanks

ADAM SMITH AND THE “MAN OF SYSTEM” – Knowledge Problem

Post by @knowledgeprob.

Source: ADAM SMITH AND THE “MAN OF SYSTEM” – Knowledge Problem

key quotes from Adam Smith:

One of the most interesting threads that ran throughout the discussion was the dimensions of Smith’s reference to the “man of system” in Theory of Moral Sentiments (paragraph VI.II.42):

The man of system, on the contrary, is apt to be very wise in his own conceit; and is often so enamoured with the supposed beauty of his own ideal plan of government, that he cannot suffer the smallest deviation from any part of it. He goes on to establish it completely and in all its parts, without any regard either to the great interests, or to the strong prejudices which may oppose it. He seems to imagine that he can arrange the different members of a great society with as much ease as the hand arranges the different pieces upon a chess-board. He does not consider that the pieces upon the chess-board have no other principle of motion besides that which the hand impresses upon them; but that, in the great chess-board of human society, every single piece has a principle of motion of its own, altogether different from that which the legislature might chuse to impress upon it. If those two principles coincide and act in the same direction, the game of human society will go on easily and harmoniously, and is very likely to be happy and successful. If they are opposite or different, the game will go on miserably, and the society must be at all times in the highest degree of disorder.

Perhaps it’s instructive to compare this “man of system” to the man of humanity and benevolence, as Smith did (paragraph VI.II.41):

The man whose public spirit is prompted altogether by humanity and benevolence, will respect the established powers and privileges even of individuals, and still more those of the great orders and societies, into which the state is divided. Though he should consider some of them as in some measure abusive, he will content himself with moderating, what he often cannot annihilate without great violence. When he cannot conquer the rooted prejudices of the people by reason and persuasion, he will not attempt to subdue them by force; but will religiously observe what, by Cicero, is justly called the divine maxim of Plato, never to use violence to his country no more than to his parents. He will accommodate, as well as he can, his public arrangements to the confirmed habits and prejudices of the people; and will remedy as well as he can, the inconveniencies which may flow from the want of those regulations which the people are averse to submit to. When he cannot establish the right, he will not disdain to ameliorate the wrong; but like Solon, when he cannot establish the best system of laws, he will endeavour to establish the best that the people can bear

 

 

Glossary of rules for the viable system

Appendix 2: Glossary of rules for the viable system (Extracted from The Heart of Enterprise Beer, 1979) to which book the page numbers refer, taken from http://kybernetik.ch/dwn/Viable_System_Model.pdf

Aphorisms

The first regulatory aphorism It is not necessary to enter the black box to understand the nature of the function it performs (p.40)

The second regulatory aphorism It is not necessary to enter the black box to calculate the variety that it potentially may generate (p.47)

Principles

The first principle of organization

Managerial, operational and environmental varieties, diffusing through an institutional system, tend to equate; they should be designed to do so with minimum damage to people and to cost. (p.97)

The second principle of organization

The four directional channels carrying information between the management unit, the operation, and the environment must each have a higher capacity to transmit a given amount of information relevant to variety selection in a given time than the originating subsystem has to generate it in that time. (p.99)

The third principle of organisation

Wherever the information carried on a channel capable of distinguishing a given variety crosses a boundary, it undergoes transduction; the variety of the transducer must be at least equivalent to the variety of the channel (p.101)

The fourth principle of organization

The operation of the first three principles must be cyclically maintained through time without hiatus or lags. (p.258)

Theorem

Recursive system theorem

In a recursive organizational structure, any viable system contains, and is contained in, a viable system (p.118)

Axioms

The first axiom of management

The sum of horizontal variety disposed by n operational elements equals the sum of vertical variety disposed on the six vertical components of corporate cohesion (p.217)

The second axiom of management

The variety disposed by System Three resulting from the operation of the First Axiom equals the variety disposed by System Four (p.298)

The third axiom of management

The variety disposed by System Five equals the residual variety generated by the operation of the Second Axiom (p.298)

Law

The law of cohesion for multiple recursions of the viable system

The System One variety accessible to System Three of Recursion x equals the variety disposed by the sum of the metasystems of Recursion y for every recursive pair. (p.355)

Guiding the Self-organization of Cyber-Physical Systems

cxdig's avatarComplexity Digest

Self-organization offers a promising approach for designing adaptive systems. Given the inherent complexity of most cyber-physical systems, adaptivity is desired, as predictability is limited. Here I summarize different concepts and approaches that can facilitate self-organization in cyber-physical systems, and thus be exploited for design. Then I mention real-world examples of systems where self-organization has managed to provide solutions that outperform classical approaches, in particular related to urban mobility. Finally, I identify when a centralized, distributed, or self-organizing control is more appropriate.

Threshold Concepts: Undergraduate Teaching, Postgraduate Training, Professional Development and School Education
A Short Introduction and a Bibliography from 2003 to 2018

The Meyer and Land Threshold Concept

The idea of threshold concepts emerged from a UK national research project into the possible characteristics of strong teaching and learning environments in the disciplines for undergraduate education (Enhancing Teaching-Learning Environments in Undergraduate Courses). In pursuing this research in the field of economics, it became clear to Erik Meyer and Ray Land [1-7], that certain concepts were held by economists to be central to the mastery of their subject. These concepts, Meyer and Land argued, could be described as ‘threshold’ ones because they have certain features in common.
Glynis Cousin, An introduction to threshold concepts

Over the past decade this concept has been embraced by many disciplines outside economics; indeed the above quote is from Glynis Cousin’s excellent short introduction to the concept written for earth scientists. The threshold concept has been seen as a valuable tool, not only in facilitating students’ understanding of their subject, but in aiding the rational development of curricula in rapidly expanding arenas where there is a strong tendency to overload the curriculum (Cousin, [20082006]). This web page will describe, briefly, the characteristics of a threshold concept and list selected references to the work of those examining its value in a broad range of disciplines.

Features of a Threshold Concept

Portal Picture

‘Threshold Concepts’ may

be considered to be “akin

to passing through a portal”

or “conceptual gateway”

that opens up “previously

inaccessible way[s] of

thinking about something”

(Meyer and Land [1]).

  • Transformative: Once understood, a threshold concept changes the way in which the student views the discipline.  >  More …
  • Troublesome: Threshold concepts are likely to be troublesome for the student. Perkins [19992006] has suggested that knowledge can be troublesome e.g. when it is counter-intuitive, alien or seemingly incoherent.   >  More …
  • Irreversible: Given their transformative potential, threshold concepts are also likely to be irreversible, i.e. they are difficult to unlearn.  >  More …
  • Integrative: Threshold concepts, once learned, are likely to bring together different aspects of the subject that previously did not appear, to the student, to be related.  >  More …
  • Bounded: A threshold concept will probably delineate a particular conceptual space, serving a specific and limited purpose.  >  More …
  • Discursive: Meyer and Land [2] suggest that the crossing of a threshold will incorporate an enhanced and extended use of language.  >  More …
  • Reconstitutive: “Understanding a threshold concept may entail a shift in learner subjectivity, which is implied through the transformative and discursive aspects already noted. Such reconstitution is, perhaps, more likely to be recognised initially by others, and also to take place over time (Smith)”.  >  More …
  • Liminality: Meyer and Land [4] have likened the crossing of the pedagogic threshold to a ‘rite of passage’ (drawing on the ethnographical studies of Gennep and of Turner in which a transitional or liminal space has to be traversed; “in short, there is no simple passage in learning from ‘easy’ to ‘difficult’; mastery of a threshold concept often involves messy journeys back, forth and across conceptual terrain. (Cousin [2006])”.  >  More …
