Knowledge that Transforms

The authors propose that consumer choices are often systematically influenced by preference fluency (i.e., the subjective feeling that forming a preference for a specific option is easy or difficult). Four studies manipulate the fluency of preference formation by presenting descriptions in an easy- or difficult-to-read font (Study 1) or by asking participants to think of few versus many reasons for their choice (Studies 2–4). As the authors predict, subjective experiences of difficulty increase choice deferral (Studies 1 and 2) and the selection of a compromise option (Studies 3 and 4), unless consumers are induced to attribute the experience to an unrelated cause. Unlike studies of decision conflict, these effects are obtained without changing the attributes of the alternatives, the composition of the choice sets, or the reference points. The authors discuss the theoretical and practical implications of the results.

This research demonstrates the strong influence of disgust in a consumer context. Specifically, it shows how consumer evaluations may change in response to physical contact with products that elicit only moderate levels of disgust. Using evidence from six studies, the authors develop a theory of product contagion, in which disgusting products are believed to transfer offensive properties through physical contact to other products they touch, thus influencing evaluations.

Three experiments show that the source of price change information—whether human or nonhuman—moderates the effect of price change on perceptions of price fairness. Both inferences of the marketer's motive and stimulus-induced affect mediate the effects of the source and price change. Opportunity and motivation to process also affect the relative influence of inferred motive and affect. This research demonstrates antecedent roles of both price source and affect.

This article proposes that compared with a promotion regulatory focus, a prevention focus increases sensitivity to the advertiser's manipulative intent. Specifically, when message cues make manipulative intent moderately salient, prevention-focused people are more likely to activate persuasion knowledge and give less favorable brand evaluations than promotion-focused people. When message cues make manipulative intent highly salient or when manipulative intent is not salient, brand evaluations do not differ across regulatory foci. In addition, externally priming suspicion of manipulative intent makes promotion-focused people react similarly to prevention-focused people, suggesting that regulatory focus affects vigilance against persuasion.

Research on choice over time has found that people tend to focus on concrete aspects of near-future events and abstract aspects of distant-future events. Furthermore, a focus on concrete aspects heightens the feasibility-related components, whereas a focus on abstract aspects heightens the desirability-related components, which can lead to preference inconsistency over time. In this research, the authors integrate research on choice over time with mental simulation. They propose and show that counter to people's natural tendencies, outcome simulation for near-future events and process simulation for distant-future events lead to preference consistency over time. The results also suggest that outcome timing moderates the effectiveness of process versus outcome simulation.

Several individual, social-setting, and choice-set factors have been shown to be related to satisfaction. This article argues that these factors operate through a set of choice goals. Using panel data on purchasers of consumer electronics, the authors examine how five goals (justifiability, confidence, anticipated regret, evaluation costs, and final negative affect) drive decision and consumption satisfaction, which in turn determine loyalty, product recommendations, and the amount and valence of word of mouth.

This article examines the effects of monitoring on interfirm relationships. Whereas some research suggests that monitoring can serve as a control mechanism that reduces exchange partner opportunism, there is also evidence showing that monitoring can actually promote such behavior. The authors propose that the actual effect of monitoring depends on (1) the form of monitoring used (output versus behavior) and (2) the context in which monitoring takes place. With regard to the form of monitoring, the results from a longitudinal field study of buyer–supplier relationships show that output monitoring decreases partner opportunism, as transaction cost and agency theory predict, whereas behavior monitoring, which is a more obtrusive form of control, increases partner opportunism. With regard to the context, the authors find that informal relationship elements in the form of microlevel social contracts serve as buffers that both enhance the effects of output monitoring and permit behavior monitoring to suppress opportunism in the first place.
