Dark triad-consumer behavior relationship: the mediating role of consumer self-confidence and aggressive interpersonal orientation

Abstract

Purpose This study aims to investigate the consumer behavior of the Dark Triad (DT) personality traits. It investigates the sequential mediating role of consumer self-confidence and aggressive interpersonal orientation in the relationship between the DT personality traits (i.e., narcissism, psychopathy and Machiavellianism) and consumer behavior. Design/methodology/approach Using identity theory as a theoretical framework, the authors develop and assess a model linking the DT personality traits to consumer behavior, using two products: a watch and restaurant menu items, in different experimental settings. Findings Results from the two studies that surveyed consumers show that individuals with the DT personality traits have a positive significance of consumers’ attitudes, intent to recommend to others and purchase intentions, regardless of hedonic or utilitarian products. Further, consumer self-confidence mediates the DT–consumer behavior relationship, and this relationship is sequentially mediated by aggressive interpersonal orientation of the consumer. Research limitations/implications Consumer behavior researchers and marketing managers will have a better understanding of who DT consumers are and the variables associated with their consumption attitudes and intentions. This understanding allows marketers to focus on promotions to boost consumer self-confidence and aggressive interpersonal orientation of these DT consumers, which will increase their purchase intentions. Future researchers could replicate the results beyond an experimental design to improve the external validity of the findings, among other future research opportunities. Originality/value Our findings highlight the underlying reasons behind dark triad consumption behaviors. This furthers our understanding of dark triad consumers using identity theory as our theoretical framework.

Analysis of the influence of enterprise managers’ overconfidence on the overinvestment behavior of listed companies under the media reports

“…However, some negative reports or news reports with exaggerated elements will affect managers’ emotions, shake managers’ confidence, and reduce investment efficiency. Blair et al (2022) verified the market pressure hypothesis of the media from an audit perspective. The media can enhance the power of external audit, reduce the motivation of enterprise profit management, and effectively realize the role of enterprise governance.…”

“… Greo (2021) and Mundi and Kaur (2022) pointed out that managers with overconfidence will be keen on enterprise expansion strategies and realize enterprise expansion by increasing investment in mergers and acquisitions, but the result will increase the possibility of companies falling into financial crisis. Blair et al (2022) refined the scope of investment and defined it as the investment in fixed assets by enterprises. The results found that the higher the level of managers’ overconfidence, the more investment in fixed assets by enterprises.…”

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

“…Narcissism and Machiavellianism act differently. Past research purported a wide overlap between the personalities of narcissism and Machiavellianism and in certain scenarios, but past researchers have not been distinct in analyzing their impact on their considered outcomes (Gala et al , 2020; Blair et al , 2022). Our research finds an exclusive behavior of these two personalities wherein they are not similar to each other.…”

“…Similarly, narcissists have also been known to demonstrate a negative relationship with ethical decision-making (Antes et al , 2007). However, the reasoning behind the unethical behavior differs between these two personality styles, with narcissists being primarily motivated by opportunities to self-promote and Machiavellians motivated by potential benefits to their own agendas (Gnambs and Appel, 2018; Jones and Paulhus, 2009; Lee and Ashton, 2017; Blair et al , 2022). Thus, understanding their interaction with relativism/idealism would bring a unique contribution to the literature, proving how they work in tandem to influence CEB.…”

Assessing impact of consumer perceived CSR on consumer attitude and purchase behaviour in retail segment: a stakeholder theory perspective

“…Further, Akintimehin et al (2022) investigated CA towards ethical consumption to engage in ethical consumption behaviour by consumers. Blair et al (2022) investigated the relationship between consumers' personality traits and CB and found positive significance. So, consumers may base their purchase decisions on their attitudes towards the environment and socially responsible retailers.…”
