Decoy Effect
The presence of a third, less attractive option can influence preferences between two other choices.
Why it works
Based on choice architecture research (Huber et al., 1982), asymmetric dominance occurs when a decoy option makes a target option appear superior. The brain uses comparative heuristics rather than absolute evaluation, making relative attractiveness more important than objective value. This violates rational choice theory but reflects actual decision-making patterns (Ariely, 2008).

Implementation tips
- Create decoy options that are slightly inferior to your target choice at nearly the same price
- A/B test different decoy configurations to find most effective combinations
- Ensure decoy options are plausible - obvious decoys reduce credibility
- Use visual emphasis (badges, highlighting) to guide attention to target option
- Test 3-option vs 2-option presentations to measure decoy impact
- Position decoy adjacent to target option for easy comparison
eCommerce fit
High Highly effective for increasing average order value and guiding customers to preferred tiers. Particularly valuable for subscription models and tiered product offerings.
Caution
Ensure decoy options provide genuine value if customers choose them - don't create fake options. Avoid manipulative practices that could damage trust or violate consumer protection laws. Test that decoy effects don't confuse or frustrate customers. Consider cultural differences in choice preferences.
