Abstract and Figures

Green product advertisements often face credibility challenges due to perceived greenwashing, contributing to the attitude‐behavior gap in green consumption. This research examines the strategic use of two‐sided messaging through five experimental studies, assessing its impact on green consumption across various product categories. We explore the nuances of message order, demonstrating that placing the negative message first can either weaken or strengthen green product purchase based on consumers' knowledge of the green product category. This finding highlights that conventional order may not always be effective, especially in green marketing, where consumer knowledge varies. Furthermore, we explore the interactive effect of consumer knowledge in two‐sided messaging involving refutational appeals. Overall, our research offers valuable insights for marketers aiming to strategically leverage two‐sided advertising to enhance green product adoption.

ABSTRACT
Green product advertisements often face credibility challenges due to perceived greenwashing, contributing to the attitude
behavior gap in green consumption. This research examines the strategic use of twosided messaging through five experimental
studies, assessing its impact on green consumption across various product categories. We explore the nuances of message order,
demonstrating that placing the negative message first can either weaken or strengthen green product purchase based on
consumers' knowledge of the green product category. This finding highlights that conventional order may not always be
effective, especially in green marketing, where consumer knowledge varies. Furthermore, we explore the interactive effect of
consumer knowledge in twosided messaging involving refutational appeals. Overall, our research offers valuable insights for
marketers aiming to strategically leverage twosided advertising to enhance green product adoption.
1 | Introduction
The global community is increasingly recognizing the importance of
environmental preservation and is actively working towards sus-
tainable practices as a collective goal. More and more brands are
embracing sustainable practices and are introducing ecofriendly
alternatives to standard product offerings (Jaiswal, Deshmukh, and
Thaichon 2022; Sreen et al. 2021). This shift is mirrored by con-
sumers who are progressively aligning their purchasing behaviors to
favor green products, demonstrating a growing commitment to
sustainable consumption (Pope 2021). Green products refer to goods
that have less impact on the environment and are less detrimental
to human health compared to the conventional alternatives (Sdrolia
and Zarotiadis 2019).
Despite the favorable trend towards green consumption, the
credibility of green advertising remains a formidable challenge
due to the prevalent skepticism surrounding greenwashing, that
is, where brands appear sustainable without genuine commit-
ment (Matthes and Wonneberger 2014; Nguyen, Chung, and
Lagace 2023). Highprofile greenwashing scandals, like Volks-
wagen's Clean Diesellie (US Justice Department 2016), Shell's
fake carbonneutralclaims (George 2021), and Unilever's
misleading environmental ads (Financial Times 2023), have
been exposed, igniting widespread consumer skepticism. These
revelations have not only tarnished brand reputations but also
severely undermined the credibility of green advertising, fueling
a wave of skepticism across green industries (Eser 2024; Sajid
et al. 2024). Recent research in Europe shows that 67% of
consumers actively seek green options, yet over 33% are skep-
tical of brands' sustainability claims (Barratt 2023). Addition-
ally, greenwashing has become a growing concern globally
(Ioannou, Kassinis, and Papagiannakis 2022; Walser 2023), with
65% of US consumers reporting skepticism towards companies'

This study analyzes the impact of greenwashing on brand avoidance and Negative Word-of-Mouth (NWOM) using a scenario-based survey conducted in malls/supermarkets. Leveraging the Stimulus-Organism-Response model, the study demonstrates how greenwashing leads to brand hate and hypocrisy, influencing consumers to avoid brands and engage in NWOM. Findings stress the need for authentic, transparent environmental practices in brand communication to reduce greenwashing perceptions. This research confirms greenwashing's negative brand effects and introduces new insights into greenwashing-brand avoidance and NWOM dynamics, contributing to the existing literature and emphasizing methodological rigor.

Consumer scepticism has attracted increasing scholarly attention in recent years. However, the scientific un-derstanding of the development and consequences of consumer scepticism towards corporate social re-sponsibility (CSR) and related programmes remains fragmented. In response, this paper reviews, synthesises and assesses the CSR-related scepticism literature from more than two decades (1998–2021) within the ante-cedents–consequences framework. In this paper, 89 studies in the existing literature are synthesised and criticallyevaluated, and the problems and gaps in the literature are highlighted. This paper also presents an attempt todevelop an integrative framework to provide a comprehensive understanding of the antecedents and conse-quences of CSR-related scepticism. Finally, it offers future research directions based on the current knowledge and gaps in the extant literature

In the context of the digital information era, consumers’ information capability plays a crucial role in shaping their green consumption intention. To delve deeper into the dynamics of how information capability influences consumers’ green consumption intention, this study constructs a theoretical model grounded in information asymmetry theory and cognitive bias theory. Additionally, the mediating role of green trust and the moderating role of media publicity are incorporated to comprehensively investigate the influence mechanism of information capability on consumers’ green consumption intention. Empirical analysis is conducted based on data collected through a questionnaire survey. The findings of this study reveal that information capability exerts a partially mediating effect on consumers’ green consumption intention. Specifically, information capability directly influences consumers’ green consumption intention, and it also indirectly impacts their green consumption intention through its influence on green trust. Furthermore, media publicity positively moderates the relationship between information capability and consumers’ green consumption intention. This research contributes to the existing literature by enhancing our understanding of the influence pathway leading to green consumption intention. Its insights offer valuable implications for promoting green consumption and advancing sustainable development initiatives.

Nowadays brands are using customization strategies to reach their consumers with experiences that perfectly fit their preferences. At the same time, with customization consumers could effectively dilute the impact of the company's brand. Despite the robust literature on customization, little attention has been paid to how the decision to customize is linked to the brand experience. This paper aims to better understand the mechanisms behind customization choice in terms of preferences and assess the role of brand experience in this decision. We hypothesize a positive relationship between customization and brand experience. Moreover, since customization has a strong emotional component, we also analyze the moderating role of cognitive and psychological factors in shifting consumer preferences—from technical performances to emotional and symbolic ones. Through a two‐equation model that encompasses a number of factors, we find strong support for the main effect of an improved brand experience when consumers are permitted to customize the offering.

Consumers, in their daily lives, tend to select and repurchase agricultural products through experience or trust. With the improvement of consumers’ quality of life, green agricultural products are now favored, and consumers have begun to pay more attention to the perceived value of green agricultural products. Based on the ABC model of attitude, this study analyzed the mechanism of consumer perceptions (safety value, functional value, and green value) of green food rice and green food apple on their behavioral intentions (repurchase intention of green agricultural products) through structural equation modeling. Based on signaling theory and cue utilization theory, the mechanism of the role of green trust in mitigating information asymmetry in the green agricultural products market was analyzed through mediating effects. To verify the applicability of the findings to specific sample groups and the impact of different sample differences on the findings, multiple-group analyses were conducted for apples and rice and high and low education. Data were collected using a questionnaire method through a cell phone random push questionnaire service on the Credamo platform, and the respondents were consumers of green food rice and green food apples distributed in all provinces of the country. The results showed that the perceived value significantly and positively influences the repurchase intention of green agricultural products. In terms of the degree of influence, the functional value is greater than the safety value, while the green value has no influence. Green trust mediates the relationship between perceived value and repurchase intention of green agricultural products, with a fully mediating role in the path from green value to repurchase intention. There is a significant difference between green value and repetitive purchase intention by the type of green products (necessities and non-essentials). In addition, education levels (low and high education) also show differences in the effects of green value on repurchase intention, the functional value on green trust, and green value on green trust. This study not only enriches the research related to perceived value theory and repurchase intention but also enriches the research related to green trust to provide some references for enhancing the external effects of trust theory.

Augmented reality (AR) has been shown to improve consumers' shopping decisions and experiences. Based on a theoretical stimulus-organism-response model and cognitive load theory, this research examines the effects that AR has on cognitive variables related to cognitive load, hitherto scarcely considered. Specifically, this research examines the impact of perceived similarity among options, confusion caused by overchoice and prepurchase cognitive dissonance on purchase-related behavioral intention variables such as purchase intention and willingness to pay for products. The study is based on consumers' AR web shopping experiences of an online cosmetics store which offers a wide assortment of products. The mixed-method research combines two focus groups and an experiment. This combination allows triangulation of the findings to provide corroboration. The results showed that AR reduces cognitive dissonance through its effects on perceived similarity and confusion caused by overchoice. Furthermore, lower cognitive load enhances purchase intentions, resulting in greater willingness to pay more for the product. The research extends knowledge of the benefits provided to consumers by AR in their decision-making through its impacts on perceived similarity, confusion by overchoice and prepurchase cognitive dissonance. The application of web AR in e-commerce shops is particularly useful when a wide assortment of similar products is offered. Online retailers can use AR to improve their economic performance both by increasing their sales’ volumes and their margins.

It has been generally assumed that higher levels of skepticism towards advertising invariably lead to higher resistance to advertising appeals. The main purpose of the present research was to examine whether highly skeptical consumers’ resistance can be overcome by appeals associated with higher credibility. We tested our hypotheses using message sidedness as an advertising variable that has been associated with higher (two‐sided) vs. lower (one‐sided) credibility. In three experimental studies, we examined more vs. less skeptical consumers’ responses to two‐ vs. one‐sided appeals. We found that two‐sided messages are more effective in increasing purchase intentions, through enhanced credibility, but only for consumers who are more skeptical of advertising. Less skeptical consumers trust both messages equally and their purchase intentions are not affected by the type of message. Importantly, we also showed that highly skeptical consumers trust two‐sided appeals as much as their less skeptical counterparts. The study contributes to the literature on advertising and persuasion knowledge by showing that advertising skepticism does not elicit a single response tendency, as originally conceptualized. Rather, advertising skepticism is more consistent with the underpinnings of the Persuasion Knowledge Model, in that higher knowledge about persuasion tactics aids consumers to better cope with, and not invariably resist persuasion attempts. We conclude that transparency pays off because it may entice a more skeptical audience and, at the same time, it does not harm less skeptical consumers’ trust and purchase intentions.

Choice deferral is a common and lousy phenomenon for companies and consumers. This research examines how visual boundaries (by-alternatives vs. attributes) interact with consumer knowledge to influence choice deferral. Five studies (N = 1,245) and two single-paper meta-analyses demonstrate that by-alternative (vs. attribute) visual boundaries reduce choice deferral and that choice difficulty mediates this effect. The research also shows that these effects are stronger for less knowledgeable consumers. However, the interactive effect of visual boundaries and consumer knowledge on choice deferral depends on task and context characteristics. We discuss future research about choice deferral moderators and how to facilitate consumer choice.
