Hobson's +1 Choice Effect
People are more likely to choose an option when a third, clearly inferior choice is added to the set.
Why it works
Based on choice architecture research (Simonson, 1989), adding an inferior third option enhances perceived autonomy while making the preferred choice appear superior by comparison. This asymmetric dominance creates the illusion of meaningful choice while guiding customers toward the intended option through contrast effects (Heath & Chatterjee, 1995).

Implementation tips
- Create decoy options that are clearly inferior to your preferred choice
- A/B test two-option vs three-option presentations to measure effectiveness
- Ensure decoy options are plausible - obvious manipulation reduces trust
- Use visual cues (badges, highlighting) to guide attention to preferred option
- Make the decoy option similar in price but clearly inferior in value
- Position the preferred option between lower and higher-priced alternatives
eCommerce fit
Medium Can be effective for guiding customer choices when used ethically with genuine options. Must balance choice optimization with customer trust and satisfaction. Requires careful implementation to avoid appearing manipulative.
Caution
Ensure decoy options provide genuine value if customers choose them - don't create fake options. Avoid manipulation that damages customer trust or satisfaction. Focus on helping customers make good decisions rather than just driving preferred choices. Consider ethical implications of choice manipulation.
