Investigating consumer ethical beliefs: role of moral philosophies and personality traits

PurposeThis research looks at the main effect of individuals' moral philosophies, idealism and relativism, and its impact on the four dimensions of the consumer ethics beliefs - active benefit, passive benefit, no harm and doing good. The moderating impact of two dominant personalities - Machiavellianism and narcissism - was also analyzed. Based on Hunt-Vitell theory of ethics, this study aims to propose that there is a positive and significant impact of more relativistic and less idealistic moral philosophies on the decreased consumer ethical perceptions and that the narcissistic/Machiavellian personality traits drive that effect. Design/methodology/approachA total of 497 survey respondents were recruited via an online platform. All respondents were asked to answer questions, which were divided into four major parts. The first part consisted of scales related to both moral philosophies, the second part had both dark personality scales, the third part questioned about their consumer ethical beliefs and the final part was related to consumer demographics. FindingsRelativists had higher scores in three consumer unethical belief dimensions. Idealists were not supportive of the active and passive illegal activities, as did their positive relation with doing good aspect of the ethical beliefs. Machiavellians strengthen the positive relativism relationship. The idealistic relation of narcissists, compared to relativistic relation, is stronger on unethical decision-making for consumers. Originality/valueThis study contributes to the current knowledge of individual's moral philosophies and their impact on consumer ethical beliefs. It further demonstrates how the dark personalities of narcissism and Machiavellianism drive the relationship.
