Every day, shoppers face a simple choice in supermarket parking lots: return the shopping cart or leave it behind. While this may seem unimportant, it reflects deeper personality traits. The “shopping-cart theory” suggests that this small action can reveal our ethical character.
Psychologists have studied how these tiny actions provide insight into our personalities. Here are five interesting traits linked to consistent cart returners.
1. Conscientiousness
Conscientious people are reliable and disciplined. Research shows that those with high conscientiousness are more likely to follow rules and finish tasks responsibly. Returning a cart ticks all the conscientiousness boxes: it completes the task, keeps the area tidy, and requires self-discipline—even on a rainy day. These small acts build a reputation for dependability over time.
2. Empathy
Empathy is about understanding and sharing others’ feelings. People with high empathy are likely to engage in helping behaviors. When you return a cart, you save the next shopper a hassle and lighten the load for staff. Cultural anthropologist Krystal D’Costa highlights that returning carts isn’t just about rules but social norms. Empathetic people think about how their actions affect others, like making things easier for the next shopper.
3. Internal Locus of Control
This concept refers to the belief that our actions shape our outcomes. Those with an internal locus of control are less likely to excuse selfish decisions. Since no one enforces cart returns, internal thinkers choose to act responsibly. This self-governance extends into various areas, such as recycling or following traffic rules even when no one is watching.
4. Future Orientation
People oriented toward the future value long-term benefits over short-term convenience. The famed Stanford marshmallow experiment shows that those who can delay gratification tend to have better life outcomes. Returning a cart may seem like a little effort now, but it contributes to a cleaner environment for everyone later. Those who prioritize future benefits often excel in areas like finance and health.
5. Civic Mindedness
Civic-minded individuals care about their community and are willing to contribute to the common good. Returning a cart is a public good action—everyone benefits, whether they return their cart or not. Those who consistently engage in community-friendly behaviors, like cleaning up after themselves in public spaces, nourish this civic spirit.
These characteristics don’t stand alone. They intertwine and support each other. Empathy enhances conscientiousness, while an internal locus of control aids in making long-term decisions.
Interestingly, while some might argue that the shopping-cart meme oversimplifies ethics, studies indicate that those who return carts do so more often than one would expect.
Even if you sometimes skip returning your cart, there are ways to cultivate these traits:
Micro-Diligence Drills: Make a small promise to yourself, like always pushing your chair in after a meal.
Perspective Prompts: Visualize who will deal with the mess if you don’t return the cart.
Form Personal Rules: Create a short code of conduct for yourself and post it where you can see it.
Explore Future-Self Journaling: Spend some time thinking about the long-term effects of small actions.
Join Community Events: Participating in group cleanup efforts reinforces civic duty and makes it enjoyable.
Returning a shopping cart might seem mundane, but it reveals a lot about who we are. This small action speaks to our character, and building good habits can enrich communities. The next time you return your cart, remember: it’s not just about tidiness; it’s about being part of a larger social fabric.
