A community of 528 homes across six buildings, home to a couple of thousand people of many nationalities, ran on a quiet habit of every family for itself. The administration spent its days answering complaints one at a time. The team drew a zoo, and within the first weeks resident conduct improved by a reported 73 percent.
The environment
The community holds 528 homes spread across six buildings, with a couple of thousand residents of many nationalities, and some of them are new to Spanish. Daily life produced a steady stream of complaints: noise, pets, parking, shared spaces, and unpaid fees. The administration met each one on its own terms, one complaint at a time, which kept the team in a loop of conflict management.
The diagnosis
Direct observation, interviews, and a review of the complaint records pointed to one cause that reframed the whole problem. Most residents knew very little about the official rules. The behavior grew from a knowledge gap, which made education the natural lever. A diverse, multilingual community received the rules unevenly, and that widened the gap. Once the cause looked like missing information, the design followed on its own: teach the rule in a way people welcome.
The method: Friendly Compliance
The intervention used a behavioral design approach called Friendly Compliance. It reframes a rule as collective care, and it uses sympathetic, culturally native characters and humor to lower defensiveness. The first touch on any behavior was a friendly paper visit from the right animal, a gentle reminder that arrived well ahead of any formal step. Formal action stayed available as a quiet last resort, and the campaign earned its results long before reaching it.
This logic lines up with what behavioral science already shows. People shift when a small, private moment of recognition reaches them, and they hold to a behavior when they feel they own it. A gentle prompt at the right moment, a cue woven into daily language, does the work that a penalty struggles to do.

The zoo, and why these animals
The campaign spoke a language the community already spoke. In Colombia these animals live in everyday speech, so the meaning landed the moment a character appeared. Each one carried a behavior that residents already recognized in it.
Turtle
Parking, and the patience it tested. A turtle is everyday shorthand for slow. The label fit twice over, because clearing a badly parked car was its own slow ordeal: call security, find the owner, and wait while the minutes stacked up.
Magpie
Noise, from raised voices to a television turned all the way up. In Colombia an urraca is already what people call a loud neighbor, a word traded back and forth in everyday teasing, so the bird landed on sight.
Donkey
Carelessness, forgotten duties, and clumsiness around shared spaces. Calling someone a burro already says careless and forgetful, so the character named the habit gently and kept things warm.
Gorilla
Aggression and disrespect, most of it aimed at the cleaning and security staff. The gorilla is the one who acts bigger than everyone else and leans on the people with the least room to answer back. Naming that made it visible, and visibility protected the staff.
Rabbit
Late and unpaid monthly fees. To “hacer conejo,” to do the rabbit, is a common local expression for slipping away from a bill. Residents knew exactly what the rabbit meant.
The drawings looked like a child made them, on purpose, because a childlike drawing softens an adult and turns a correction into something almost tender. People saw a behavior in a character they already found familiar, and forgivable.
How it worked in practice
The mechanic stayed simple. A behavior earned a friendly visit from its animal first, a single sheet of paper that arrived as a gentle reminder. People found the characters charming, and that warmth did the work, because empathy is the engine behavior change runs on.
Around the campaign, the team made two structural changes. They retrained the administrative and security staff to apply the rules fairly and to calm situations down. And they rewrote the coexistence manual so the rules read clearly and felt accessible, and residents recognized themselves in it and welcomed it.
What changed
Within the first weeks, resident conduct improved by a reported 73 percent. The administration moved from an overwhelmed complaint desk toward a community that increasingly regulated itself. Residents began using the campaign’s own vocabulary to remind each other, gently.
The deepest change was cultural. The community grew a shared sense of responsibility, and an institutional proposal became a shared norm, which is where behavior change becomes permanent.
A financial loop reinforced it. An early-payment discount lifted compliance and rebuilt a sense of fairness. The recovered money went visibly back into the building, into better lighting and cleaner common areas people could see, which closed the loop between paying in and getting something back.
The honest remainder
The portion that stayed asked for a different kind of help. Some residents were living with a private health condition or an addiction, some carried a financial strain, some traveled often and arrived back after the rules had moved on, and a few situations reached the office quietly through their own families. Clearing the general friction is what made this group visible, and that visibility is the quiet value of the number. Once these residents stood out clearly, the administration could guide them toward specialized, confidential support. The rules reached everyone, the campaign eased the friction, and this first rollout left clear room to keep lowering the figure over time. Knowing this limit is part of the method.
What it transfers to any organization
This case travels far beyond one building, because organizations meet the same pattern. Most non-compliance grows from a knowledge gap, and education reaches it directly. Speak the language people already use, and the message lands on its own. Reach for the simplest cue woven into daily life. Build shared norms, because belonging is what makes a new behavior stick. And keep the economics in view: human-centered design grounded in behavioral science delivers outsized returns on a small budget.
The same defensiveness that leads a resident to wave off a parking sign is the one that leads an employee to wave off a security policy. Lower the defense, and the behavior follows.
The method
Friendly Compliance: reframing a rule as collective care, using sympathetic, culturally native characters and humor to lower defensiveness, well ahead of any penalty. It began as behavioral research and proved itself in the field.
A rule earns its welcome the day people feel it protecting them.
