Popularizing Systems Thinking

Models of complex behavior increasingly sit at the background of vital political discussions like global warming and pandemics. It is time to make them a more integral part of our political discussion. Until voters can understand and participate developing models to predict the behavior of systems, we will have unstable politics, particularly in a country like ours that puts so much stock in the opinion of everyone. This country was defined by a way of thinking. It’s time to expand that.

Our founding fathers did not pioneer Enlightenment thinking but they were the first to create a community organized around it. The Enlightenment shifted people from a reliance on authority and tradition (church and king) to reason and debate (science and democracy). Our founding fathers popularized education – most notably, Thomas Jefferson founded the University of Virginia – with an emphasis on rhetoric and analysis as essential to creating smart voters. They generally believed that education was necessary to freedom and democracy. But as it turns out, rhetoric is a poor way to understand or communicate complexity. We need to update what constitutes a good education.

Today we have expert systems thinkers but we haven’t popularized systems thinking, made it a part of the way we organize and act or even a part of what we include in education. Analysis focuses on parts at one point in time; systems thinking focuses on interactions over time, like how viruses spread at different rates depending on how we behave or how CO₂ builds in the atmosphere depending on our technology. Systems thinking is as important to an effective democracy in this 21^st century as Enlightenment philosophy was to an effective democracy in the 19^th and 20^th centuries. We can’t coherently debate systems as varied and crucial as our financial, environmental, education, and healthcare systems with fluency in systems thinking.

Hearing Bill Gates talk about a pandemic in 2015 and how serious it will be, he mentions what "our models told us." Listening to California governor Gavin Newsom in press conferences, he, too, references "our models." Models have the potential to explain futures we haven't yet experienced. Models will never be perfect; they can, however, be sufficient to inform good policy.  Once you understand compound interest, you may not be able to predict how much wealth you’ll have in 30 years but you know what to do: invest early and often to maximize that wealth. Once you understand how rapidly the coronavirus can spread, it informs policies like shelter-in-place. Even though models are sensitive to changes in assumptions and inputs, they can still point us in the right direction. The better people understand them, both their limits and the insights they provide, the more credible and helpful these models.

I work with really bright scientists and engineers to plan – or model – their projects to develop new products like drugs, medical devices and computer chips. Two benefits inevitably follow. One, each person gets insights into what others are doing and how that impacts them. Good models are key to coordination. Two, they learn more of what is possible as they play with the model, play a game of “what if” to see how they might accelerate launch. “What if we hired one more circuit engineer?” “What if we doubled the number of clinical trial sites so that we could enroll patients more quickly?” The models let them answer what-if questions and become tools for making really smart people even smarter, in the same way that a spreadsheet can help a financial planner to get and communicate insights. Models that a group jointly creates and maintains could be used to inform an entire populace about their policy options on issues like economic stimulus, global warming, or the spread of a pandemic. Even very simple models can help to illustrate important dynamics more clearly than rhetoric.

Democracy depends on education. Change is accelerating. We’re increasingly dependent on systems. Education needs to include system thinking. In a crisis like a pandemic, we have to react to what the models predict about consequences because if we wait to react to actual consequences or rely on our intuition (intuition informed by completely different circumstances) our actions will be tragically late. Models let us learn from the past and from possible futures. The AI that recently beat the world champion Go player Ke Jie was able to make a move no one had ever before seen, a move learned from millions of game simulations it had simulated play even before playing its “first” game with Ke Jie. When a community encounters something like the coronavirus, it would be nice to be at least as prepared as one might be for a game of Go.

There are a variety of ways to popularize systems thinking. One way might look like video games. Imagine kids learning about global warming or economic development by getting exposed to simple models that play out over time. They first learn to turn the knob on this variable and then that variable. They see which variables are akin to the butterfly's wings in Brazil that causes a snowstorm in Minneapolis and which are akin to a hundred moths beating their wings uselessly against a light bulb. Over time they begin to introduce their own data, their own variables, or even change the structure of the model. The class as a whole could build a model that represents their collective insights and predicts outcomes few – if any – minds are sophisticated enough to foresee.

Good education changes life outside the classroom. Eventually democracy might mean that we have collective, online models that represent our best knowledge and are as widely understood as an op-ed or debate. Policy could come out of millions of simulations that are largely transparent and contributed to and understood by millions of citizens. Perhaps working on models will become as much a part of citizenship as working on campaigns or reading and arguing about op-eds. In the same way that a car lets us travel further than we could on foot, good models can let us create better policy than we can with debates.
