Abstract
Purpose The purpose of this study was to examine the impact of unsubstantiated claims that a product is "ecological ."Design/methodology/approach A between-subjects experimental design was used in which the absence versus the presence of an (unsubstantiated) ecological claim regarding a product was a manipulated factor. The design comprised four products, representing non-ingestible/ingestible products and familiar/unfamiliar brands. These two aspects were seen as potentially moderating factors with respect to the impact of ecological claims. Findings The results show that ecological product claims boosted beliefs that a product is indeed ecological. This influence was not moderated by non-ingestible/ingestible and familiar/unfamiliar product characteristics. Moreover, ecological product claims enhanced conceptually related product beliefs, namely, beliefs that the product is natural, environmentally friendly and healthy. Ecological claims also had a positive impact on the attitude toward the product. Practical implications The results imply that influencers who want a receiver to believe that a product is ecological can expect to be successful by merely claiming that a product is ecological. Social implications From a societal point of view, however, and in an era in which "alternative facts" and "post-truths" are becoming the subject of increasing concern, the results are problematic, because they underline that customers can be made to believe in claims even though no supporting evidence is provided.
