The Decoy Effect

How a Third Offer Can Influence Consumers to Choose Your Target Option

Imagine you’re at a café, deciding between a small and large coffee. Then, the barista introduces a medium coffee. But here’s the twist – the medium coffee is priced just slightly lower than the large one. Suddenly, you feel like the large coffee is a better deal, even though you never intended to buy it in the first place. This sneaky trick is known as the decoy effect, and it’s a powerful tool marketers use to influence consumer choices. By introducing a third option (the decoy), businesses can make the original choice seem more appealing, even if it wasn’t before.

Background:

The decoy effect was first widely recognized by psychologists Dan Ariely, along with his colleagues, in the early 2000s. In his groundbreaking work, Ariely explored how seemingly irrelevant options (the "decoys") could nudge consumers toward a specific choice without them even realizing it. The decoy, which is often an unattractive or overpriced option, makes one of the other choices appear more appealing, even though the consumer didn’t initially consider it.

Historical Experimentation:

In 2002, Dan Ariely and his team conducted a famous experiment to demonstrate the decoy effect. The experiment, titled “The Decoy Effect in Consumer Choice,” was published in the Journal of Consumer Research. The researchers presented participants with two choices: a small and a large subscription to The Economist magazine. However, they introduced a third option: a medium-sized subscription priced just slightly lower than the large one. Most participants who were given the three options chose the large subscription, despite having no prior preference for it. This experiment showed that the introduction of a decoy, a third, less attractive option, significantly increased the likelihood that people would choose the larger option. The implications were clear: the decoy effect was a powerful tool for manipulating consumer decisions.

Connection to Human Evolution/Biology/Neuroscience:

The decoy effect taps into an instinctive human behavior rooted in evolutionary psychology. Our ancestors often faced situations where they needed to make quick decisions to maximize value (for example, choosing between different food sources or survival tools). The human brain has developed mechanisms to make these decisions efficiently. When presented with a decoy, our brain uses a shortcut, the contrast effect, to make judgments based on comparison rather than independent evaluation. This cognitive shortcut may have helped our ancestors quickly determine which option was the most valuable, a skill that, when applied to modern-day consumer choices, is used against us.

Recent Research & Experimentation:

In 2017, a study titled "Decoy Effect in Online Choices" published in the Journal of Consumer Psychology by researchers from the University of California, Berkeley, expanded upon Ariely's original findings. This experiment was conducted by Dr. John A. Bargh and his team, who tested the decoy effect in online environments. They found that, much like in previous studies, introducing a decoy (such as a slightly more expensive version of a product) increased the likelihood that consumers would choose the higher-priced item. The implications of this research extended beyond physical stores to the world of e-commerce, where companies can subtly manipulate product pricing and layouts to nudge consumers toward specific products.

Conclusion:

The decoy effect is a compelling example of how psychological principles can be used to guide consumer behavior. For businesses, understanding and leveraging this effect can be a game-changer in pricing strategies. By carefully designing product options and introducing a decoy, businesses can make their target product seem like the best value, even when it might not be the most attractive at first glance. If you’re a marketer or business owner, consider your pricing and product layouts. A well-placed third option could be just what you need to guide customers toward your desired choice, boosting sales and enhancing your overall strategy.
