The False Confidence of Simple Answers
Strong Towns programs are built around humility, feedback, and learning our way forward.
Last weekend, I took my daughter Stella to see the movie Pressure.
The film tells the story of the 72 hours leading up to D-Day and the agonizing decision facing General Dwight Eisenhower. The success of the invasion depended on a narrow window of acceptable weather in the English Channel. Launch too soon and tens of thousands of soldiers could be caught in a storm. Wait too long and the Germans might discover the invasion plans.
At the center of the story is a disagreement between meteorologists.
One forecaster is confident. He looks at historical weather patterns and insists conditions will be favorable. He tells the generals what they want to hear. The invasion can proceed.
Another forecaster, the Scottish meteorologist James Stagg, is far less certain. He sees the same weather system and reaches a very different conclusion. The atmosphere is changing rapidly. The available data is incomplete. The consequences of being wrong are enormous. He believes there is a storm approaching, but he cannot say exactly what it will do or precisely when it will arrive.
At one point, Stagg refers to the other forecaster as a moron. The line got a laugh from the audience, but it captured something profound. The issue wasn’t that the other man lacked intelligence. The issue was that he lacked humility.
Anyone who truly understood the complexity of the situation would have recognized how much uncertainty remained. The more Stagg learned, the less confident he became.
I’ve been obsessing about that ever since. In part, it’s because this is such a difficult posture to maintain in public. People are drawn to certainty. They reward it. They interpret hesitation as weakness and humility as a lack of conviction, especially when the stakes are high and a decision needs to be made.
But Stagg’s uncertainty wasn’t weakness. It was the product of understanding. That is the quintessential Strong Towns insight about cities: They are complex, adaptive systems. The more honestly we understand them, the more cautious we should become about claims of certainty.
The Confidence We Reward
One of the strangest things about modern city-building is that we ask people to make decisions about extraordinarily complex systems while rewarding them for projecting certainty.
Traffic engineers confidently forecast traffic volumes twenty years into the future. Economic development consultants confidently forecast job growth. Housing advocates confidently predict what will happen if a city adopts a particular reform. Politicians confidently promise outcomes. Neighborhood activists confidently predict disaster.
Everyone seems remarkably certain. And yet cities are among the most complex systems humans have ever created.
A city is not a machine. It is not a bridge. It is not a chemistry experiment.
A city is millions of individual decisions layered on top of decades, sometimes centuries, of accumulated history. It is infrastructure, institutions, markets, culture, habits, incentives, relationships, geography, and luck all interacting at the same time.
The more time I have spent working with cities, the more skeptical I have become of certainty. Not because expertise doesn’t matter. And not because data is unimportant. It’s because the people who understand cities best are often the ones most aware of how much they do not know.
That realization has shaped nearly everything we do at Strong Towns.
One of the common criticisms of Strong Towns is that we don’t offer enough simple answers. There is some truth to that. We are suspicious of simple answers. Not because we enjoy complexity for its own sake, but because cities are complex whether we acknowledge it or not. Pretending otherwise may feel reassuring, and it might help us advance our cause in the short term, but it doesn’t make us wiser.
One of the most dangerous habits in city-building is confusing confidence with competence. The confident person often sounds persuasive. They have projections. They have charts. They have a plan. They know exactly what will happen if we simply follow their recommendations. People are naturally drawn to that kind of certainty. It feels like leadership.
Sometimes it even works, just often enough to reinforce the illusion.
But when we are dealing with complex systems, false confidence becomes a substitute for learning, and learning is what cities need most.
Learning Our Way Forward
The Strong Towns response to complexity is not to stop acting. Paralysis is its own kind of failure.
Cities have to make decisions. Streets need to be built or repaired. Budgets need to be balanced. Projects need to move forward or be abandoned. There is no option where we simply wait until the system is fully understood before doing anything.
The question is: How do we act responsibly, prudently, and productively when we know we don’t know enough? What do we do in the face of uncertainty?
A lot of our work at Strong Towns can be understood as an attempt to answer that question.
Crash Analysis Studio
Take the Crash Analysis Studio. After a crash, the most common response is to look for the person to blame. The driver was distracted. The pedestrian wore dark clothing. The cyclist should have been more careful. There is always a way to reduce the tragedy to a single decision made by a single person, and sometimes that explanation is not entirely wrong.
It is just radically incomplete.
A crash is not merely an event. It is the product of a system: street design, speed, visibility, land use, lighting, enforcement, expectations, habits, signals sent to drivers and pedestrians long before anyone reached the intersection, and so on. The Crash Analysis Studio is not built around the premise that we already know the answer. It is built around the discipline of slowing down, looking closely, and asking what the system was telling people to do.
That is a very different posture than blame. It is also a very different posture than certainty.
And yet it is not passive. In fact, it is remarkably productive. Once you stop looking for a single cause, you begin noticing dozens of opportunities for improvement. A crossing that is too long. A turn that encourages excessive speed. A signal that sends conflicting messages. A land use pattern that puts people in conflict with fast-moving traffic.
The goal is not to find the one thing that caused the crash. The goal is to identify many small things that can make the next crash less likely. The more honestly we engage with the complexity of the system, the more opportunities we discover to make it better.
The Housing-Ready City
The same thing is true with housing. There are people who will tell you, with complete confidence, that the answer is to build more units. There are others who will tell you, with equal confidence, that the answer is to stop the wrong kind of development. Both can point to examples that support their view. Both can sound persuasive. Both can flatten a complex problem into a campaign slogan.
We take affordability more seriously than that.
Housing affordability is not merely a question of whether a city technically allows more units. It is a question of what kinds of homes can be built, who is able to build them, how they are financed, and whether the local system is capable of responding to real needs in real time. A city can legalize more housing on paper and still fail to create homes people can afford. A community can talk endlessly about affordability while relying on a distant financing system that rewards large, expensive, debt-dependent projects.
Our Housing-Ready work leans into that complexity instead of pretending it away.
Yes, cities need to remove the small, practical barriers that make ordinary homes illegal. They need to allow the kinds of homes that used to be normal: backyard cottages, duplex conversions, starter homes, small lots, and modest infill. But that is only one part of the work.
Someone still has to build those homes.
That means helping local people step forward: homeowners, tradespeople, small builders, local investors, and neighbors who understand their place well enough to build carefully within it. These are not the people our current housing system is designed to support. The process is confusing. The financing is difficult. The risks are personal. Many never get started, not because they lack interest or ability, but because the path is too hard to see.
So the work is not merely to change the code. It is to build the ecosystem.
And then there is finance, which may be the hardest part of all. The housing finance system is distant, standardized, and largely indifferent to the small, local, entry-level housing we most need. We can wish that system worked differently, or we can ask what local governments, local lenders, and local leaders can do right now to make bottom-up projects more viable.
That is the Strong Towns approach to affordability. Not a slogan. Not a promise that one reform will solve everything. A complete theory of change rooted in the complex reality that housing is shaped by local rules, local capacity, local builders, and distant capital systems that often do not work in our interest.
The point is not to pretend we can control the entire system. We can’t.
The point is to identify where we do have agency, act there, learn from what happens, and build capacity for the next step.
Finance Decoder
Finance Decoder comes from the same instinct. Local governments are full of confident stories about growth.
This project will expand the tax base. That development will pay for itself. This grant will bring prosperity. This annexation will position us for the future.
Maybe.
But how would we know?
One of the most remarkable things about local government is how much energy is devoted to forecasting future success and how little attention is paid to measuring the results of past decisions. Cities spend enormous amounts of time debating what might happen and comparatively little time asking what actually happened.
Did that development generate enough value to justify its long-term obligations? Did that infrastructure investment make the city financially stronger? Did that economic development project improve the community’s ability to sustain itself? Are residents wealthier? Is the city more resilient? More productive? Better positioned than it was twenty years ago?
These are not ideological questions. They are feedback questions, yet most local governments struggle to answer them. They have budgets, audits, capital plans, consultant reports, and economic forecasts. What they often lack is a practical way to understand whether the pattern of growth they have pursued is actually working.
That gap creates an opening for confident stories.
If we don’t know how previous investments performed, then every new proposal can be sold as the next big opportunity. Every subsidy can be justified. Every expansion can be framed as progress. Every grant can be celebrated as free money. The story never has to confront reality because there is no meaningful feedback loop.
Finance Decoder is our attempt to create one.
Not by predicting the future, nor by claiming to know exactly what will happen next, but by helping communities better understand the financial consequences of the choices they have already made.
The goal is not certainty. The goal is learning.
Once a city begins measuring what creates value and what creates liabilities, the conversation changes. Decisions become less dependent on optimism, fear, ideology, or wishful thinking. Local leaders gain a clearer understanding of where their community is strong, where it is fragile, and where the next productive investment might be made.
Just as the Crash Analysis Studio helps us learn from tragedy and the Housing-Ready approach helps us learn from incremental action, Finance Decoder helps communities learn from their own experience.
And in a complex system, that may be the most valuable information we can obtain.
Mission Accomplished
Mission Accomplished comes from the same place. For generations, transportation policy has been built around one confident assumption: expansion is progress. More lanes. More interchanges. More capacity. More funding. More construction. The larger the project, the more serious it seems.
That story made sense for a while. The United States set out to build a national transportation system, and in many ways, it succeeded. We connected regions, expanded mobility, and built one of the most extensive roadway networks in the world.
The problem is that institutions rarely know what to do when their mission has been accomplished. They keep going.
The models still project future demand. The funding systems still reward expansion. The professions still organize themselves around large capital projects. Politicians still cut ribbons. Communities still celebrate grants. Everyone involved can tell a confident story about why the next project is necessary.
Meanwhile, cities and states are struggling to maintain what they already have.
That is the complexity transportation advocates often avoid. It is not enough to ask whether a project improves travel time or reduces congestion on paper. We also have to ask whether the system we are expanding can be sustained. Whether the local tax base can support the long-term maintenance. Whether each new lane, interchange, frontage road, or arterial adds more strength than fragility.
Most of the time, that question is not seriously asked.
Mission Accomplished is not an argument that transportation no longer matters. It matters enormously. The argument is that the era of expansion has ended, whether our institutions recognize it or not. The work before us is not to keep building out a system as if the continent remains unconnected. The work is stewardship: maintenance, safety, repair, and the hard discipline of making better use of what we already have.
That requires a different kind of confidence than the one our current system rewards.
It requires enough confidence to stop doing what no longer works. Enough humility to admit that the old mission has succeeded and now imposes costs we can no longer ignore. Enough honesty to recognize that the next big project may not make a community stronger, even if it comes with federal money and a compelling model.
In a complex system, success can become failure if we refuse to learn from it.
Mission Accomplished is our attempt to create that learning moment for transportation. To help communities step back from the momentum of expansion and ask what the actual mission should be now.
Not more. Better.
A Different Way to Govern
These four efforts may seem very different on the surface, but they all begin from the same place.
They begin with the recognition that cities are complex systems and that our understanding will always be incomplete. That is not a reason for inaction. It is a reason for humility.
It is a reason to be skeptical of simple stories and sweeping promises. It is a reason to build feedback loops instead of relying on forecasts. It is a reason to favor learning over certainty, adaptation over rigid plans, and many small opportunities for improvement over a single grand solution.
In other words, it is a reason to act like James Stagg instead of the meteorologist who thought he had everything figured out.
Strong Towns members make this work possible.
Not because they are funding a predetermined agenda or a fixed set of policy prescriptions. They are supporting a different way of approaching change itself. One rooted in curiosity rather than ideology. Observation rather than assumption. Humility rather than hubris.
That approach is often slower than the alternatives. It is certainly less dramatic. It rarely produces the kind of simple slogans or confident predictions that attract headlines and applause.
But cities are not simple systems. They never have been.
The communities that become stronger are not the ones that find certainty. They are the ones that learn. They learn from their mistakes. They learn from their successes. They learn from one another. They learn from reality itself.
And then they take the next step.
This week, we are celebrating the members who make that work possible.
If you are already a member, thank you. Your support helps communities ask better questions, learn from their experience, and discover practical ways forward in the face of uncertainty.
And if you are not yet a member, consider joining us. Not because we have all the answers, but because helping communities learn their way toward a stronger future may be the most important work any of us can do.
If you have thoughts you want to share on any of this, you can continue this conversation with me and other members in the Strong Towns Commons.
For every problem, there is a solution that is simple, neat, and wrong.
H. L. Mencken
I have concluded that simplification is abuse. We can rightfully hope to explain complex matters in simpler terms to help people learn, but efforts to make the world simpler cannot avoid unforeseen and unintended results.
