About This of book Summary epub: Thinking in Systems: A Primer [Paperback]. Jake implements living systems thinking and understanding of ecological patterning, collaborative cultures, systemic solutions, resource cycles, community engagement and human ecology to create unique solutions. This review walks us through the model presented by Donella Meadows in her paper on places to intervene in a system. Each component of the model is examined and explained. The leverage points in a system where intervention is possible and the resulting effects of those interventions are also explained. • Meadows (2000) '. In: The Global Citizen, November 30, 2000. Thinking in Systems: A Primer (2008) [ ] Donella H. Meadows, edited by Diana Wright, Thinking in Systems: A Primer,, 2008 (). • A is a set of things – people, cells, molecules, or whatever – interconnected in such a way that they produce their own pattern of behavior over time. [.] The system, to a large extent, causes its own behavior! • Ever since the Industrial Revolution, Western society has benefited from science, logic, and over intuition and holism. Psychologically and politically we would much rather assume that the cause of a problem is “out there,” rather than “in here.” It’s almost irresistible to blame something or someone else, to shift responsibility away from ourselves, and to look for the control knob, the product, the pill, the technical fix that will make a problem go away. Serious problems have been solved by focusing on external agents – preventing smallpox, increasing food production, moving large weights and many people rapidly over long distances. Because they are embedded in larger systems, however, some of our “solutions” have created further problems. And some problems, those most rooted in the internal structure of complex systems, the real messes, have refused to go away. Hunger, poverty, environmental degradation, economic instability, unemployment, chronic disease, drug addiction, and war, for example, persist in spite of the analytical ability and technical brilliance that have been directed toward eradicating them. No one deliberately creates those problems, no one wants them to persist, but they persist nonetheless. That is because they are intrinsically systems problems – undesirable behaviors characteristic of the system structures that produce them. They will yield only as we reclaim our intuition, stop casting blame, see the system as the source of its own problems, and find the courage and wisdom to restructure it. Part one: systems structure and behavior [ ] • If a government proclaims its interest in protecting the environment but allocates little money or efforts toward that goal, environmental protection is not, in fact, the government's purpose. Purposes are deduced from behaviour, not from rhetoric or stated goals. • In fact, one of the most frustrating aspects of systems is that the purposes of subunits may add up to an overall behavior that no one wants. • Dynamic systems studies usually are not designed to predict what will happen. Rather, they're designed to explore what would happen, if a number of driving factors unfold in a range of different ways. • That very large system, with interconnected industries responding to each other through delays, entraining each other in their oscillations, and being amplified by multipliers and speculators, is the primary cause of business cycles. Those cycles don't come from presidents, although presidents can do much to ease or intensify the optimism of the upturns and the pain of the downturns. Economies are extremely complex systems; they are full of balancing feedback loops with delays and they are inherently oscillatory. • Whenever we see a growing entity, whether it be a population, a corporation, a bank account, a rumor, an epidemic, or sales of a new product, we look for the reinforcing loops that are driving it and for the balancing loops that ultimately will constrain it.

We know those balancing loops are there, even if they are not yet dominating the system's behavior, because no real physical system can grow forever. [.] An economy can be constrained by physical capital or monetary capital or labor or markets or management or resources or pollution. Part two: systems and us [ ] • Like resilience, self-organizazion is often sacrificed for purposes of short-term productivity and stability. • There always will be limits to growth. They can be self-imposed. If they aren't, they will be system-imposed. No physical entity can grow forever. If company managers, city governments, the human population do not choose and enforce their own limits to keep growth within the capacity of the supporting environment, then the environment will choose and enforce limits. • Changing the length of a delay may utterly change behavior. [.] Overshoots, oscillations, and collapses are always caused by delays. • Pages 104-105. • Bounded rationality means that people make quite reasonable decisions based on the information they have. But they don't have perfect information, especially about more distant parts of the system. [.] We don't even interpret perfectly the imperfect information that we do have, say behavioral scientists. [.] Which is to say, we don't even make decisions that optimize our own individual good, much less the good of the system as a whole. • Pages 106-107. • Economic theory as derived from Adam Smith assumes first that homo economicus acts with perfect optimality on complete information, and second that when many of the species homo economicus do that, their actions add up to the best possible outcome for everybody. Neither of these assumptions stands up long against the evidence. • These examples confuse effort with result, one of the most common mistakes of this kind is designing systems around the wrong goal. Maybe the worst mistake this kind has been the adoption of the GNP as the measure of national economic success. [.] If you define the goal of a society as GNP, that society will do its best to produce GNP. It will not produce welfare, equity, justice, or efficiency unless you define a goal and regularly measure and report the state of welfare, equity, justice, or efficiency.

Part three: creating change – in systems and in our philosophy [ ] • Growth has costs as well as benefits, and we typically don't count the costs – among which are poverty and hunger, environmental destruction, and so on – the whole list of problems that we are trying to solve with growth! What is needed is much slower growth, very different kinds of growth, and in some cases no growth or negative growth. Donella Meadows Thinking In Systems Pdf To Jpg FileThe world's leaders are correctly fixated on economic growth as the answer to virtually all problems, but they're pushing it with all their might in the wrong direction. • Power over the rules is real power. That's why lobbyists congregate when Congress writes laws, and why the Supreme Court, which interprets and delineates the Constitution – the rules for writing the rules – has even more power than Congress. If you want to understand the deepest malfunctions of systems, pay attention to the rules and to who has power over them. • Even people within systems don't often recognize what whole-system goal they are serving. Donella Meadows Thinking In Systems Pdf To Jpg Free'To make profits', most corporations would say, but that's just a rule, a necessary condition to stay in the game. What is the point of the game? Donella Meadows Thinking In Systems Pdf To Jpg ConverterTo grow, to increase market share, to bring the world (customers, suppliers, regulators) more and more under the control of the corporation, so that its operations becomes ever more shielded from uncertainty. • The shared idea in the mind of society, the great big unstated assumptions, constitute that society's paradigm, or deepest beliefs about how the world works. [.] people who have managed to intervene in systems at the level of paradigm have hit a leverage point that totally transforms systems. • Pages 162-163. • How is it that one way of seeing the world becomes so widely shared that institutions, technologies, production systems, buildings, cities, become shaped around that way of seeing? • Why are they [people] more likely to listen to people who tell them they can't make changes than they are to people who tell them they can? • You've seen how information holds system together and how delayed, biased, scattered, or missing information can make feedback loops malfunction.
