Partially Green, Wholly Deceptive? How Consumers Respond to (In)Consistently Sustainable Packaged Products in the Presence of Sustainability Claims
研究揭示，当产品仅部分可持续（如包装更环保但成分不变）且宣传夸大时，消费者会感到被欺骗，降低购买意愿，即使他们认可部分改进的价值。
Firms often emphasize “green” benefits for products that are only partially more sustainable than alternatives (e.g., a more sustainable packaging with similar product ingredients). The current article posits that such strategies can lead to a perceived claim–fact discrepancy and examines to what extent this makes consumers feel deceived and detracts from attitudes and purchase intentions, even though consumers can intrinsically value the (partial) sustainability improvements. In addition, given that marketing communication often relies on puffery such as exaggerated language and (visual) hyperbole, the article also investigates the effect of the use of puffery versus more subdued claims. Findings from two experiments unveil that when the actual sustainability of packaged products is (partially) discrepant with an overt sustainability claim, this leads to higher perceived deception. The use of puffery has both pros and cons, such that it adds to perceived sustainability but also to perceived deception, and it moderates the effects of actual sustainability. Furthermore, the results provide initial support for the idea that sustainability improvements in only peripheral attributes (packaging) are perceived as more deceptive than sustainability improvements in only central attributes (product contents).
