In marketing, the decoy effect (or attraction effect or asymmetric dominance effect) is a phenomenon in consumer decision-making in which the inclusion of unattractive third option can change the perceived preference between the other two. This third option is asymmetrically dominated when it is inferior in all respects to one option; but, in comparison to the other option, it is inferior in some respects and superior in others.
