Have You Seen a Fly Painted in Airport Urinals? There's Real Science Behind It
Explore how a small painted fly in airport urinals demonstrates the power of behavioral science to influence behavior and improve outcomes in everyday life.

Introduction
If you’ve ever been to an airport restroom, you might have noticed something peculiar: a small fly painted inside the urinals. While it might seem like a quirky design choice, this detail has a profound scientific explanation. It's a brilliant example of how subtle interventions can significantly influence human behavior and improve everyday experiences.
The Idea Behind the Painted Fly
The painted fly was introduced as a cost-effective solution to a common issue—maintaining cleaner restrooms. By adding a small, realistic-looking fly to the urinal bowl, designers provided users with a visual target to aim at. This simple design significantly reduced spillage, thereby lowering cleaning costs.
Studies have shown that this approach can lead to notable improvements in restroom hygiene, with reductions in cleaning needs often exceeding 50%. All of this is achieved without any rules or enforcement, relying purely on instinctive human behavior.
The Science That Makes It Work
The painted fly embodies the concept of a “nudge,” a term popularized in behavioral economics. A nudge is a subtle intervention that influences people’s decisions and behaviors in a predictable way without restricting their freedom of choice or significantly altering incentives.
Behavioral economics is a discipline that combines insights from psychology and economics to understand how people make decisions, often diverging from purely rational choices. It explores how various factors, like emotions, social influences, and cognitive biases, shape human behavior. For more information, you can read about Behavioral Economics here.
This concept is extensively explored in the book Nudge: Improving Decisions About Health, Wealth, and Happiness by Richard H. Thaler and Cass R. Sunstein. The book illustrates how small changes in the environment, like the painted fly, can influence behavior in positive ways.
How the painted fly works
The painted fly works by tapping into basic psychological tendencies:
- Target fixation: Humans naturally focus on and aim at visible targets.
- Gamification: The fly creates a subtle, playful challenge that users instinctively engage with.
- Subconscious influence: Without realizing it, people modify their behavior, achieving the desired outcome effortlessly.
This simple nudge demonstrates how small environmental cues can lead to big changes in behavior.
Beyond Restrooms: Applications of Nudges
The idea behind the painted fly—using small, thoughtful cues to influence behavior—extends far beyond airport restrooms. Nudges like these are applied in many areas, including digital design, sustainability, and public health, to guide behavior effortlessly and promote positive actions without restricting choices.
What Can We Learn from the Fly?
The painted fly may seem like a small, quirky detail, but it carries a powerful lesson: thoughtful design can harness human psychology to create meaningful improvements. By understanding and applying these principles, we can design environments that subtly guide behavior in a positive direction without imposing restrictions.
Next time you encounter a fly in a restroom, remember—it’s not just decoration; it’s science at work, making the world a little cleaner and smarter.
Stay tuned for more examples of how behavioral economics and smart design impact our day-to-day lives in unexpected ways.
