| Summary: | Product aesthetics can enhance consumer welfare in numerous ways. Aside from simply making products more pleasurable, product aesthetics can also influence the inferences that consumers make about functional attributes. In some instances, an attractive design can accurately provide information regarding utility. In other instances, however, an attractive design can be a misleading signal that prompts consumers to assume more utility than justified. Across five studies, the present research examines whether aesthetics can exert an unwarranted influence on the estimation of missing attribute information in favor of an aesthetically superior product. We show that aesthetics can bias consumers’ inferences about functionality, sometimes overriding other more diagnostic information. Boundaries to this effect are also identified that may serve to correct the bias and preserve consumer welfare.
