The introduction of inferior 'decoy' options can modestly, yet measurably, influence consumer purchasing decisions in complex, real-world market environments. This innovation & markets research insight is drawn from a 2025 study published in npj Science of Learning. Using Observational data analysis with 3,600,000 transactions, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Consider the strategic placement and design of product options, including potentially less attractive alternatives, to influence consumer preference towards specific targets.

Key Findings
- 01Decoy options significantly increased the likelihood of consumers choosing a target option, consistent with the attraction effect.
- 02The strength of the decoy effect was modest, resulting in approximately a 1% change in preference.
- 03The impact of decoy options was influenced by individual consumers' past purchasing histories.
Application
Design takeaway
Consider the strategic placement and design of product options, including potentially less attractive alternatives, to influence consumer preference towards specific targets.
How to apply
When designing product lineups or promotional offers, consider introducing a carefully selected 'decoy' product that makes a target product appear more attractive by comparison.
Project actions
- 01When designing a product range, think about how the options relate to each other.
- 02Consider if a slightly less appealing version of a product could make your main product seem better.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Large-scale, real-world dataset provides high ecological validity.
- +Novel methodology for detecting choice biases in complex environments.
Limitations
The effect size is small, so it might not be noticeable in small-scale tests. The 'inferiority' of a decoy needs to be carefully defined and context-dependent.
Reliability & validity
The large sample size and real-world transaction data lend high external validity. The study's methodology for identifying decoy effects in complex data is a key strength for internal validity.
Think critically
To what extent is the use of decoy options manipulative, and where is the ethical line between influencing choice and exploiting cognitive biases?
Design Principles
"Choice architecture can be leveraged to subtly influence decision-making by carefully curating the options presented to consumers."
Understanding how subtle contextual cues like decoy options impact consumer choice is crucial for effective product positioning and marketing strategies. This research demonstrates that even small shifts in preference can be statistically significant in large-scale markets, informing how businesses design their product portfolios and present options to consumers.
What This Means for Your Design
Sometimes, if you show people a bad option alongside two good ones, they're more likely to pick one of the good ones. This study found that happens even when people are just buying wine in a real shop, and it makes a small difference.

Paragraph starter
This research demonstrates that decoy options can subtly influence consumer choice in real-world markets. By introducing an inferior option, the likelihood of selecting a target option can be increased, albeit by a modest margin. This principle of choice architecture suggests that careful consideration of product portfolio design and presentation can strategically guide consumer decision-making.
