Educators From The United States

"A delay in a balancing feedback loop makes the system likely to oscillate."

"The least obvious part of a system, its function or purpose, is often the most crucial determinant of the system's behavior."

"No one can define or measure justice, democracy, security, freedom, truth, or love. [...] But if no one speaks up for them, if systems aren't designed to produce them, if we don't speak about them and point toward their presence or absence, they will cease to exist."

"Our culture, obsessed with numbers, has given us the idea that what we can measure is more important than what we can't measure. Think about that for a minute. It means that we make quantity more important than quality."

"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?"

"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?"

"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."

"Even people within systems don't often recognize what whole-system goal they are serving. "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? To 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."

"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."

"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. The 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."

"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."

"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."

"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."

"Changing the length of a delay may utterly change behavior. [...] Overshoots, oscillations, and collapses are always caused by delays."

"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."

"Like resilience, self-organization is often sacrificed for purposes of short-term productivity and stability."

"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."

"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."

"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."

"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."

"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."

"Ever since the Industrial Revolution, Western society has benefited from science, logic, and reductionism 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."

"A system 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!"

"Systems thinking can only tell us to do these things. It can't do them for us. And so we are brought to the gap between understanding and implementation. Systems thinking by itself cannot bridge that gap. But it can lead us to the edge of what analysis can do and then point beyond—to what can and must be done by the human spirit."

"Expand the boundary of caring."

"Seeing systems whole requires more than being "interdisciplinary," if that word means, as it usually does, putting together people from different disciplines and letting them talk past each other. Interdisciplinary communication works only if there is a real problem to be solved, and if the representatives from the various disciplines are more committed to solving the problem than to being academically correct."

"Don't be stopped by the "if you can't define it and measure it, I don't have to pay attention to it" ploy. No one can [precisely] define or measure justice, democracy, security, freedom, truth, or love. No one can [precisely] define or measure any value. But if no one speaks up for them, if systems aren't designed to produce them, if we don't speak about them and point toward their presence or absence, they will cease to exist."

"Pay attention to what is important, not just what is quantifiable."

"If I could, I would add an Eleventh Commandment: Thou shalt not distort, delay, or sequester information."

"Pretending you're in control even when you aren't is a recipe not only for mistakes, but for not learning from mistakes. What's appropriate when you're learning is small steps, constant monitoring, and a willingness to change course as you find out more about where it's leading."

"Before you charge in to make things better, pay attention to the value of what's already there."

"And finally, starting with history discourages the common and distracting tendency we all have to define a problem not by the system's actual behavior, but by the lack of our favorite solution. (The problem is, we need to find more oil. The problem is, we need to ban abortion. The problem is, how can we attract more growth to this town?)"

"The world is a complex, interconnected, finite, ecological–social–psychological–economic system. We treat it as if it were not, as if it were divisible, separable, simple, and infinite. Our persistent, intractable global problems arise directly from this mismatch."

"Models can easily become so complex that they are impenetrable, unexaminable, and virtually unalterable."

"Starting with the behavior of the system forces you to focus on facts, not theories. It keeps you from falling too quickly into your own beliefs or misconceptions, or those of others."

"Before you disturb the system in any way, watch how it behaves. If it's a piece of music or a whitewater rapid or a fluctuation in a commodity price, study its beat. If it's a social system, watch it work. Learn its history."

"The future can't be predicted, but it can be envisioned and brought lovingly into being. Systems can't be controlled, but they can be designed and redesigned. We can't surge forward with certainty into a world of no surprises, but we can expect surprises and learn from them and even profit from them."

"Calculating how much carbon is absorbed by which forests and farms is a tricky task, especially when politicians do it."

"In recent years it has become impossible to talk about man's relation to nature without referring to "ecology"...such leading scientists in this area as Rachel Carson, Barry Commoner, Eugene Odum, Paul Ehrlich and others, have become our new delphic voices...so influential has their branch of science become that our time might well be called the "Age of Ecology"."

"Clearly, we have compiled a record of serious failures in recent technological encounters with the environment. In each case, the new technology was brought into use before the ultimate hazards were known. We have been quick to reap the benefits and slow to comprehend the costs."

"The peak of the [Presidential] campaign happened in Albuquerque, where a local reporter said to me, "Dr. Commoner, are you a serious candidate or are you just running on the issues?""

"You will need find your passion. Many of you have already done it, many of you will later, many of you may take to your thirties or forties, but don't give up on finding it. Right, then all you are doing is waiting for the reaper. Find your passion and follow it. And if there is anything that I have learned in life, you will not find that passion in things. And you will not find that passion in money. Because the more things and the more money you have, the more you will just look around and use that as the metric — and there will always be someone with more. Your passion must come from the things that fuel you from the inside. And honors and awards are nice things, but only to the extent that they regard real respect from your peers. And to be thought of well by people you think of more highly up is a tremendous honor I've been granted. Find your passion, and in my experience, no matter what you do at work or what you do in in official settings, that passion will be grounded in people. It will be grounded in the relationships you have with people and what they think of you when your time comes."

"It is not the things we do in life that we regret on our death bed. It is the things we do not. I assure you I've done a lot of really stupid things, and none of them bother me. All the mistakes, and all the dopey things, and all the times I was embarrassed — they don't matter. What matters is that I can kind of look back and say: Pretty much any time I got chance to do something cool I tried to grab for it — and that's where my solace comes from."

"We don't beat the reaper by living longer, but by living well, and living fully — for the reaper will come for all of us. The question is: what do we do between the time we're born and the time he shows up. Because when he shows up, it’s too late to do all the things that you’re always gonna, kinda get around to."

"Treat the Disease, Not the Symptom."

"Do not tell people how to live their lives. Just tell them stories. And they will figure out how those stories apply to them."

"We all stand on the dart board and very few of us catch the darts. Do not think it is unfair. It is fair but you are unlucky."

"Never give up: There are certain times that you think, “OK, you have beaten me down to my knees. And now the challenge is, I am on my knees and you keep on beating me down. And the question is, are you going to keep beating me all the way to the ground or will I find a way to struggle my way back on to my feet.”"

"The key question to keep asking is, Are you spending your time on the right things? Because time is all you have.""

"Look, I'm going to find a way to be happy, and I'd really love to be happy with you, but if I can't be happy with you, then I'll find a way to be happy without you.""
