This phenomenon suggests that when people group several individual items together, they tend to evaluate the group itself more positively. This may explain why, when selling a bundle of products, the grouped items are perceived as having a higher value than when sold individually. For example, items on a particular restaurant menu may be perceived as less valuable when listed individually, but when the same items are presented as a “set menu,” the group as a whole may be perceived as more attractive. This can be used to provide consumers with a variety of choices and value, and to facilitate purchase decisions.
