How do you design a city where the healthy choice is the easy one?
We try to get people moving with awareness campaigns about health, step counters, fitness apps, cycling subsidies. And here is the awkward fact that should give us pause: the Netherlands has one of the highest rates of cycling in the world and rising obesity at the same time.[2] Movement is not automatically baked into a culture. It is baked into infrastructure, or it is not.
So the more useful question is not how to persuade people to move more, but how to design a city where moving is simply the easiest thing to do. The places that get this right do not have more motivated citizens. They have better-designed streets.
What the infrastructure does
Cities that put walking routes, wide protected cycle paths and green space at the centre of their infrastructure end up with healthier residents. Not because those residents are more disciplined or more health-conscious, but because the environment invites movement every single day. In a city built for cycling, people cycle, and it has little to do with willpower. The bike path is wide, protected and direct. The car parking is far away and expensive. The easy, obvious choice is the bike.
The infrastructure is the intervention. The campaign urging people to be active is, by comparison, almost beside the point. You do not so much choose the bike as get chosen for it by the street.
Why this is design, not willpower
It is tempting to credit cycling cultures to some special national virtue or willpower. The truth is more about tarmac than character. Drop the same person into a city where cycling is direct and pleasant and driving is slow and costly, and they cycle, whatever their level of health motivation. Move them to a city built around the car, and they drive. The behaviour follows the infrastructure, not the inner resolve.
Which means getting a population moving is far less a matter of persuasion and far more a matter of which option the built environment makes easiest.

The science: the default and the path of least resistance
The principle underneath this is the power of the default and the path of least resistance. People overwhelmingly take whichever option requires least effort in the moment, because the mind treats effort as a cost to avoid. When the healthy choice is also the easy, default choice, people make it far more often, without any conscious decision to be healthy. When it requires fighting the environment, a long detour on an unprotected bike lane, a cycle park further than the car, most people quietly take the easier, less healthy route, whatever their good intentions.
Good cycling infrastructure is a textbook example of arranging the environment so the desired behaviour is the path of least resistance.[1] The protected, direct lane and the inconvenient, costly car trip together make the bike the default, and the default is what most people choose.
Through a Behavioural Design lens: building the default
It is worth naming the discipline here, because urban movement is a clear case of the gap between intention and action. People genuinely intend to be healthier; the gap is that intention lives in the slow, deliberate mind while the moment-to-moment choice is made by the fast, automatic one, which reaches for whatever is easiest right now. Awareness campaigns aim squarely at the intention and almost entirely miss the moment of choice. That is why they so reliably fail to shift behaviour at scale.
Cycling infrastructure works because it changes the moment of choice itself. It does not try to strengthen anyone's resolve. It makes the healthy option the one that takes least effort, so the automatic mind selects it without any act of will. This is the behavioural design move in one of its purest forms: rather than pushing harder on motivation, you redesign the situation so the behaviour you want is simply the easiest available, and let people walk, or cycle, straight into it. At SUE, the Influence Framework and SWAC are the methods we teach in the Behavioural Design Fundamentals Course to systematically analyse how the built environment triggers behaviour and where you can redesign the path.
What this means in practice
Start with your own habits, because the default runs more of your day than your willpower does. You are far more likely to keep up an exercise habit when the kit is by the door and the gym is on your route than when you have to summon discipline against an inconvenient setup. The useful move is not to want it more. It is to redesign your own situation so the healthy or productive option is the easy one, and the alternative takes a little more effort.
For anyone leading people, this reframes how you get a behaviour to stick. The instinct is to motivate: explain why the new way matters, urge people towards it. Far more effective is to make the desired behaviour the path of least resistance and the old one slightly harder, so people drift into the new way without a fight. You are not strengthening their resolve; you are changing which option the moment of choice naturally reaches for.
And at the level of the organisation and its customers, this is one of the most powerful and most ignored levers you have. Whatever behaviour your defaults make easiest is the behaviour you will mostly get, regardless of what your messaging asks for. The skill this teaches is to stop trying to motivate the behaviour you want and start engineering it as the path of least resistance, the way a good cycle lane turns a healthy choice into the obvious one.
Learn to apply this yourself
What makes cycling infrastructure effective is not persuasion but path design: when the built environment makes one behaviour easier than the alternative, most people take it without a second thought. In the Behavioural Design Fundamentals Course you learn to use the Influence Framework and SWAC to map exactly where that friction sits in any situation and redesign the path so the behaviour you want becomes the obvious default.

You will not be laying cycle lanes, but the underlying move works on any behaviour you want more of. Three ways to start:
Make the good choice the easy choice. Whatever behaviour you want, from yourself, a team or a customer, shorten and smooth the path to it. The option that takes least effort is the one most people take.
Add friction to the alternative. A protected bike lane works partly because the car trip is made slow and costly. Where you want less of a behaviour, make it take a little more effort rather than banning it.
Stop campaigning, start engineering. If a behaviour is not happening, resist the urge to add another message aimed at the intention. Change the situation so the moment of choice reaches for what you want.
The Netherlands did not produce healthier cyclists by lecturing people about fitness. It built streets where the bike was the easiest way to get around, and let movement follow. That is the difference between campaigning for a behaviour and designing for it, and it works on a personal habit, a team and an organisation alike.

Frequently asked questions
Why does cycling infrastructure change behaviour when health campaigns don't?
Campaigns address intention, which lives in the slow, deliberate mind. The actual moment of getting on or off a bike is handled by the fast, automatic mind, which simply reaches for whatever is easiest right now. A campaign saying "cycle more for your health" never touches that moment. A protected, direct cycle lane that makes the bike faster and simpler than the car does. The infrastructure changes what the automatic mind selects, without requiring any act of will from the person.
How do I apply the path-of-least-resistance principle to a behaviour I want at work?
The article's core move is straightforward: make the desired behaviour the option that requires least effort, and add a little friction to the alternative. If you want a team to use a new process, make it shorter and simpler to start than the old one, rather than explaining again why it matters. If you want less of something, make it take a small extra step rather than banning it. Stop adding messages aimed at motivation and start changing which option the situation naturally presents first.
What does the automatic mind actually do at the moment of choice?
The automatic mind treats effort as a cost to avoid. In any moment of choice, it scans for the option that can be taken with least energy and selects that one, largely outside conscious awareness. This is why the article distinguishes between intention and action: the intention to cycle more, eat better or work differently lives in the deliberate mind, but that mind is not running most of your daily decisions. The automatic mind is, and it follows the path of least resistance regardless of what the deliberate mind decided earlier that morning.
The Netherlands has high cycling and rising obesity — doesn't that show the limits of design?
It shows the opposite. Cycling infrastructure makes everyday movement the default for millions of people, and it works. Obesity is rising because the food environment has moved in the opposite direction: ultra-processed food is cheaper, more present and requires less effort to choose than whole food does. Two different environments, pulling in two different directions, producing two different outcomes at the same time. The conclusion is not that design has limits; it is that the design of the food environment is winning the battle the cycling infrastructure is winning for movement.
