Crowdsourcing has become an increasingly popular way for marketers to conceive of and design new products. Promoting these with “designed by consumers” claims has proven highly effective in boosting innovation appeal and market success. However, beyond the appeal of the perceived similarity between co-contributors and customers (Dahl et al., 2015), little is known about the effectiveness of different communication strategies for crowdsourced products. Central to the current investigation is the crucial creative strategy decision about whether to show the co-contributor in the advertisements and the persuasive role of the co-contributor’s level of physical attractiveness. The use of attractive sources is highly prevalent in standard advertisements and is known to have reliable positive effects in persuading consumers (Mello et al., 2020). In contrast, our research suggests that showing attractive co-contributors in advertisements for crowdsourced products undermines their unique appeal and can even backfire. Through a series of qualitative and experimental studies, we found that this effect results from two mechanisms: (1) negative persuasion knowledge, where consumers question whether the attractive source is the genuine co-contributor, and (2) disruption of the similarity appeal that typically makes crowdsourced products well-received. These findings not only advance our understanding of the effectiveness of “designed by consumers” claims but also contribute significantly to the broader communication and persuasion literature. Importantly, our findings provide managers with actionable strategies for maximizing the commercial success of crowdsourced products.

Brands are increasingly engaging in social marketing campaigns that take stances on important social issues. Such campaigns can garner considerable awareness and effectively encourage consumers to purchase the focal brand. However, they can also outrage other consumer segments who disapprove of the brand’s social stance. While social campaigns that outrage consumer groups would normally be undesirable, our research investigates how they can alternatively have a positive impact for brands that support the attacked value. This prediction is based on the premise that outrage expressed towards a social campaign threatens the value involved, causing consumers who want to defend that value to engage in symbolic protective responses by strengthening self-brand connections and increasing purchase intentions. Five experiments validate this theorizing, and further show that these social threat effects are moderated by the type of outgroup that expressed the outrage and the level of viral support the expressed outrage received. Implications for the social marketing and brand relationship literatures are discussed.

We suggest that thematic ad–medium congruency versus incongruency evokes distinct effects on consumer evaluations through different underlying mechanisms. Specifically, we propose congruency largely has positive effects on consumer evaluations due to a relatively automatic fluency process, whereas incongruency evokes a more conscious and negative persuasion knowledge (PK) process that leads to negative evaluations. Study 1 showed that consumers were more attentive to incongruence than congruence, particularly when the ad–medium combination was presented with other ads or materials. Studies 2A and 2B confirmed that congruency led to positive evaluations through perceived fluency, whereas incongruency led to negative-PK thoughts involving manipulative intent and more negative evaluations. Studies 3A and 3B provided causal evidence for the role of PK by showing that positive PK attenuated the negative effects the incongruency tactic had otherwise. Overall, these findings suggest the common practice of directly comparing congruent and incongruent media tactics confounds two very different processes. Managerial implications for advertising and media marketing are discussed.

Misleading information pervades marketing communications, and is a long-standing issue in business ethics. Regulators place a heavy burden on consumers to detect misleading information, and a number of studies have shown training can improve their ability to do so. However, the possible side effects have largely gone unexamined. We provide evidence for one such side-effect, whereby training consumers to detect a specific tactic (illegitimate endorsers), leaves them more vulnerable to a second tactic included in the same ad (a restrictive qualifying footnote), relative to untrained controls. We update standard notions of persuasion knowledge using a goal systems approach that allows for multiple vigilance goals to explain such side-effects in terms of goal shielding, which is a generally adaptive process by which activation and/or fulfillment of a low-level goal inhibits alternative detection goals. Furthermore, the same goal systems logic is used to develop a more general form of training that activates a higher-level goal (general skepticism). This more general training improved detection of a broader set of tactics without the negative goal shielding side effect.

Using an associative judgment framework, the authors examine the implications that negative feedback about counterfeit performance can have on subsequent evaluations for both the imitated genuine brand and competing genuine brands. Findings from two studies suggest that poor–quality counterfeits can carry over to produce negative evaluations for the target brand and closely associated competitors, but not to weakly associated competitors. These negative carry–over effects were qualified by country–of–origin differences and increased cognitive elaboration. These findings have important theoretical and managerial implications for the problems that counterfeits pose to genuine brands.

Product safety warnings are pervasive in the marketplace. The frequency and, in some cases, content of such warnings has led some to speculate that the cumulative effects may undermine the efficacy of warnings in general—including that of different warnings for other products. According to the generalized desensitization hypothesis, numerous past warnings can cause consumers to react less strongly to safety warnings for other products subsequently encountered. In contrast, the literature on goal activation and compensatory consumer behavior suggests that any self-protective goals aroused by initial warnings can potentially generalize to increase awareness and safety precautions in other warning contexts, consistent with the generalized sensitization hypothesis. The authors tested both hypotheses by manipulating the number and strength of an initial set of product warnings and examining whether such exposure generalized to different product warnings. In support of the generalized sensitization prediction, prior warnings motivated appreciation of the risks communicated in a different warning context and increased relevant safety behaviors. These generalized sensitization effects were moderated by self-affirmation, supporting the prediction that they are driven by self-protective goals.

We suggest that thematic ad–medium congruency versus incongruency evokes distinct effects on consumer evaluations through different underlying mechanisms. Specifically, we propose congruency largely has positive effects on consumer evaluations due to a relatively automatic fluency process, whereas incongruency evokes a more conscious and negative persuasion knowledge (PK) process that leads to negative evaluations. Study 1 showed that consumers were more attentive to incongruence than congruence, particularly when the ad–medium combination was presented with other ads or materials.

Studies 3A and 3B provided causal evidence for the role of PK by showing that positive PK attenuated the negative effects the incongruency tactic had otherwise. Overall, these findings suggest the common practice of directly comparing congruent and incongruent media tactics confounds two very different processes. Managerial implications for advertising and media marketing are discussed.

Accuracy goals are central to communication theory. Consistent with this perspective, a comprehensive review suggests that rumors are spread largely for accuracy reasons—either because transmitters, in fact, believe the rumors are true or for the purpose of verification through sense-making (DiFonzo and Bordia 2007). This literature also suggests that rumors can be spread in service of social goals such as affiliation (Rosnow 1991), for instance, by passing on social rumors about disliked out-groups to strengthen ties with the in-group. Our own research focused on brand rumors and suggests that entertainment is a common reason that such rumors are shared. Moreover, we show entertaining rumors serve social affiliation goals, and that the social benefits of spreading entertaining rumors can dominate private concerns about their inaccuracy. Social goals also led consumers to embellish the rumors they spread in order to make them more entertaining and to share rumors over factual brand information. These entertainment effects are shown to be independent of any alternative sense-making or affect sharing explanations for transmitting questionable rumors. Theoretically speaking, the entertainment effects identified here offer a novel explanation for the spread of questionable or implausible rumors. That is, we show consumers will knowingly spread implausible rumors just because they offer a good story for entertaining others. This idea has important practical implications for brand strategies dealing with misleading rumors.

The endowment effect is one of the most robust and well-studied phenomena in the behavioral decision literature. The dominant explanation for this effect is that loss aversion and/or the psychological value of ownership changes the subjective valuation of an item. The current research presents evidence for an alternative account of endowment that requires no shift in subjective value. We argue that (a) individuals will only agree to exchange (i.e., buy and sell) if they perceive some minimum net gain, an exchange surplus, and (b) existing work cannot disentangle the possible effects of an exchange surplus from genuine shifts in subjective value because ownership and exchange are confounded in standard demonstrations of the endowment effect. Four experiments test this idea by separating the effects of exchange from ownership in various ways. Results indicate that exchange has a substantial effect on prices, that this effect appears to be independent of subjective valuation, and that it can explain valuation differences ordinarily ascribed to ownership. We discuss why individuals might demand an exchange surplus and the implications of this for monetary valuation.

Dans le domaine de la consommation pro-environnementale, les recherches se sont évertuées ces dernières années à expliquer l’écart existant entre les attitudes et les comportements effectifs. Trois études expérimentales montrent que lorsque la contradiction entre ce que les individus disent et ce qu’ils font est rendue saillante, c’est-à-dire dans une situation d’hypocrisie induite, ils réduisent de manière indirecte la dissonance cognitive qui en résulte en étant plus altruistes à l’égard d’associations qui agissent pour l’environnement mais pas pour des associations humanitaires. Cet effet de l’hypocrisie induite n’est plus significatif lorsque les individus ont pu, au préalable, affirmer leur Soi.

In the field of ethical consumption, research in recent years has attempted to explain the gap between principles and actual behaviour. Three experimental studies show that when the contradiction between what individuals say and what they do is made salient in the field of environmental protection, that is to say in a situation of induced hypocrisy, they indirectly reduce the resulting cognitive dissonance by being more altruistic towards associations that act for the environment but not towards humanitarian associations. This effect of induced hypocrisy fades as individuals become less vulnerable to the threat to the self by affirming values that are important to them.

E-commerce offers retailers the opportunity to attract new customers online; however, consumer distrust toward unfamiliar retailers can seriously impede these efforts. Construal Level Theory suggests that such distrust can be partially understood in terms of psychological distance, and that reducing psychological distance using simple website tactics should overcome distrust and encourage first-time purchases. Studies 1 and 2 show a physically distant retail store, or lack of a physical store altogether, contribute to psychological distance, distrust, and reluctance to purchase online. Studies 2 and 3 further show that website images of an office building (increased tangibility), or the owner’s name and appearance (social proximity), can improve trust and purchase intentions by specifically reducing the psychological distance otherwise associated with purely virtual or physically distant retailers.

Marketers often advocate the use of targeted promotional strategies because they are presumed more effective. However, common targeting variables (gender and age) can also serve to stereotype some consumers (female or older) as more vulnerable to sales pressure. The current research shows that this can cause sales agents to target these stigmatized groups with inferior products. In contrast, encouraging sales agents to empathize with target customers was effective in reducing the targeting of these groups with substandard items. Implications are discussed.

The use of idealized advertising models has been heavily criticized in recent years. Existing research typically adopts a social comparison framework and shows that upward comparisons with models can lower self-esteem and affect, as well as produce maladaptive behavior. However, the alternative possibility that consumers can cope with threatening advertising models by excelling in other behavioral domains has not been examined. The present research draws on fluid compensation theory (Tesser, 2000) and shows that idealized models motivate improved performance in consumer domains that fall outside that of the original comparison. These more positive coping effects operate through self-discrepancies induced by idealized models, rather than self-esteem or negative affect. Specifically, self-discrepancies motivate consumers to improve decision-making by: 1) making more optimal choices from well-specified consideration sets, and 2) better self-regulating indulgent choices. More broadly, the current research integrates and extends theories of fluid compensation and self-discrepancy, as well as provides a more complete picture of the ways in which consumers cope with idealized advertising models.

In a process the authors term just world coping, some consumers use positive beliefs concerning the general benevolence of the world as a resource to cope with marketplace threat. This belief buffers or even, ironically, enhances trust judgments in the face of threat. Three experiments and one replication show that, whereas consumers who do not hold this belief respond to decision-generated threat with distrust, trust is significantly higher for those who believe in a just world (optimistic trust effect). Process evidence shows such coping is automatically activated in response to threat but can be corrected for more normative considerations when an obvious ulterior motive is present. Finally, evidence this coping serves an ego-protective function is provided by manipulating whether consumers are directly threatened. Overall, findings are consistent with the view that belief in a just world operates as a positive illusion that allows consumers to cope with decision threat.
