The Psychology of Vending Machines

Armchair Psychology: Why Do We Love Vending Machines?

Vending machines bring more to the table than just convenience; they provide a unique and unexpectedly satisfying UX (user experience) that keeps us coming back for more. 

There’s something strangely appealing about vending machines, though it’s difficult to pinpoint exactly why. What makes pressing a button and getting a snack so satisfying?

It’s not just a happy accident. The answer lies in a combination of psychological factors that have been carefully considered in their design. Let’s look into the psychology behind this seemingly simple machine.

“We humans love instant rewards”

Delay discounting is where people place a higher value on immediate rewards over future ones, even if the future reward is larger. It’s the tendency to “discount” or reduce the perceived value of something if there’s a delay in receiving it.

Vending machines maximise on our love for instant gratification. The simple act of pressing a button and receiving a snack immediately satisfies our desire for quick rewards. This is the power of delay discounting in action.

“We’re more likely to indulge when we feel in control”

The allure of autonomy is the psychological appeal of having control over our own choices and actions. Humans naturally desire freedom and independence, and making our own decisions—even small ones—provides a sense of empowerment and satisfaction. 

Without salespeople, queues, or judgmental eyes, we have the freedom to choose our snack or drink at our own pace. This sense of autonomy, the ability to make a purchase without external influence, is a powerful psychological draw. 

“When we see the item in front of us, it creates a strong desire to reach for it”

Vending machines offer a unique and satisfying visual experience. We can see the exact product we want in full before we buy it. This visual display taps into our sensory psychology. When we see the actual snack, drink, or item in front of us, it creates a stronger desire to reach for it. 

The transparent front of a vending machine creates a sense of anticipation as we watch the robotic arm reach out and select our chosen product, heightening the satisfaction of receiving it. This satisfying experience adds a touch of excitement to the simple act of purchasing a snack.

“Humans are attracted to nostalgia”

Vending machines often stock familiar brands and snacks that many of us grew up with, creating a powerful sense of nostalgia. This nostalgic pull taps into our love for the familiar, transporting us back to simpler times and places. 

The effect is especially comforting in environments like hospitals, schools, or airports, where stress and uncertainty can run high. In these settings, a familiar treat offers the comforting taste of the nostalgia. The comforting effect of nostalgia is a big part of why people gravitate toward vending machine, finding something familiar and satisfying.

“When we invest our time, we don’t want to leave empty-handed”

The sunk cost fallacy is a cognitive bias that occurs when people continue to invest in something, such as time, money, or effort, because they’ve already invested in it, even if it’s no longer rational to do so.

In the context of vending machines, customers who’ve already spent time browsing the options may feel compelled to make a purchase to justify their investment of time, even if they don’t really want anything. Essentially, the time invested creates a psychological pull, encouraging them to walk away with a snack or drink, rather than leaving empty-handed. This is why offering a variety of choices can encourage longer browsing times and increase the likelihood of a purchase.

“We are more likely to treat ourselves to small, easily justifiable luxuries”

The small indulgence effect is a psychological phenomenon where customers feel comfortable treating themselves to small, inexpensive luxuries. 

Because these treats are minor expenses, they don’t trigger the same feelings of guilt that larger indulgences might. 

Vending machines attract customers with their affordable luxuries, tapping into the small indulgence effect. 

The appealing price of a chocolate bar or a packet of crisps makes it simple to justify that little treat. Because these purchases are small, they don’t come with feelings of remorse, allowing customers to enjoy a treat without a second thought.
