    Displaying enthusiasm (an emotional manifestation of passion) is a common practice for entrepreneurs to attract crowdfunding. However, we propose that funders may attribute an entrepreneur’s displayed enthusiasm to impression management motives, which can in turn reduce their funding intentions. Moreover, this negative pathway is more likely to occur when the entrepreneur is perceived to have lower domain expertise. We found consistent support for these hypotheses from a survey and an experiment. Our findings suggest that displaying enthusiasm may not always be effective for entrepreneurs because there are both positive and negative pathways underlying the influence of displayed enthusiasm on funders.

    Mixed or inconsistent opinions are commonplace in online reviews. Research shows that review inconsistency has different effects: its product-level manifestation (e.g., in terms of inconsistent product ratings) is associated with poorer sales, but its review-level manifestation (e.g., in terms of two-sided arguments in an individual review) is associated with better review-level evaluations such as perceived review helpfulness and credibility. In practice, consumers rarely consult all reviews or a single review before they make purchase decisions. Instead, they often read a set of featured reviews (i.e., a review set) and some additional reviews if needed. Focusing on inconsistency in a review set, we introduce a new form of inconsistency across reviews that does not exist within a single review or at the level of product ratings: cross-review incoherence. Based on Cognitive Dissonance Theory, we explore how and when cross-review incoherence influences helpfulness and credibility judgments of the review set, revealing how reactions to such incoherence might operate differently beyond an individual review. In addition, we examine how and why consumers’ judgments of a review set influence their purchase deferral—i.e., the likelihood of making a “buy/not buy” decision immediately after consulting the top reviews or deferring it until after obtaining more information. Two laboratory experiments demonstrate that cross-review incoherence increases purchase deferral via more negative evaluations of the review set and reduced attitude certainty, and that the negative effect on review set evaluations is weaker when the reviewers provide more specific context behind their opinions. These findings deepen our understanding of inconsistency across multiple pieces of information, reveal the consequences of review evaluations during an under-studied stage of the consumers’ decision-making process, and provide critical implications for review platforms, companies, and reviewers.

  3. Lei, Z., Yin, D., Mitra, S., & Zhang, H. (forthcoming). Swayed by the Reviews: Disentangling the Effects of Average Ratings and Individual Reviews in Online Word-of-Mouth. Production and Operations Management. [AbstractAbstract] [PDF]

    Online word-of-mouth studies generally assume that a product’s average rating is the primary force shaping consumers’ purchase decisions and driving sales. Similarly, practitioners place more emphasis on average ratings by displaying them at more salient places than individual reviews. In contrast, emerging evidence suggests that individual reviews also affect the decision-making of those consumers who consult both kinds of information. However, because average ratings and individual reviews are often correlated and confounded empirically, little research has attempted to disentangle their effects. To address this empirical challenge, we construct trade-off situations in which the average ratings and top-ranked reviews of different product options do not align with each other. We then investigate consumers’ preferences that can indirectly reveal the relative impact of average ratings vs. top reviews. Through an archival analysis of a panel dataset and two laboratory experiments, we find consistent evidence for a swaying effect of individual reviews and reveal their textual content as a likely reason. These findings challenge the commonly accepted assumption of average ratings being the primary driver of consumers’ purchase decisions and suggest that consumers may not be as rational as previous literature assumed. In addition, this paper is the first to disentangle the effects of average ratings and individual reviews on consumer decision-making and to explore a possible reason for the swaying effect of individual reviews. Our paper illustrates the importance of information accessibility in consumers’ purchase decisions, and our findings offer valuable insights for product manufacturers, online retailers, and review platforms.

    A common assumption in prior research and practice is that more helpful online reviews will exert a greater impact on consumer attitudes and purchase decisions. We suggest that this assumption may not hold for reviews expressing anger. Building on Emotions as Social Information (EASI) theory, we propose that although expressions of anger in a negative review tend to decrease reader perceptions of review helpfulness, the same expressions tend to increase the negative influence of the review on reader attitudes and decisions. Results from a series of laboratory experiments provide support for our claims. Our findings challenge the widely accepted assumption that more “helpful” reviews are ultimately more persuasive, and they extend current understanding of the interpersonal effects of emotion in online communication. Our findings also suggest implications for review platforms, retailers, marketers, and manufacturers faced with the task of managing consumer reviews.

  5. Lei, Z., Yin, D., & Zhang, H. (2021). Focus Within or On Others: The Impact of Reviewers’ Attentional Focus on Review Helpfulness. Information Systems Research, 32(3), 801-819. [AbstractAbstract] [PDF]

    When reviewers write online reviews, they differ in the focus of their attention: some focus on their own experiences, whereas some direct their attention to others—prospective consumers who may read the reviews in the future. This paper explores how, why, and when reviewers’ attentional focus can influence the helpfulness evaluation of reviews beyond the impact of substantive review content. Drawing on the attentional focus and persuasion literatures, we develop a theoretical model proposing that reviewers’ attentional focus may influence consumers’ perception of review helpfulness through opposing processes, and that its overall effect is contingent on the review’s two-sidedness. Results of one archival analysis and five controlled experiments provide consistent support for our hypotheses. This work challenges the predominant view of the positive impact of other-focus (vs. self-focus), explores the interpersonal impact of a reviewer’s attentional focus on prospective consumers who are total strangers, and reveals an important, context-specific boundary condition.

    Given the popularity and prevalence of medical question-and-answer (Q&A) services, it is increasingly important to understand what constitutes a helpful answer in the medical domain. Prior studies on user-generated content have examined the independent impacts of content and source characteristics on reader perception of the content’s value. In the setting of medical Q&A sites, we propose a novel content-context congruence perspective with a focus on the role of congruence between an answer’s content and the answer’s contextual cues. Specifically, we identify two types of contextual cues critical in this unique setting—the language attributes (i.e., concreteness and emotional intensity) of the question’s content, and the acuteness of the disease to which the question is related. Building on the priming literature and construal-level theory, we hypothesize that an answer will be perceived as more helpful if the language attributes of the answer’s content are congruent with those of the preceding question, and if they are congruent with the disease’s acuteness. Analyses of a unique data set from WebMD Answers provide empirical evidence for our theoretical model. This research deepens our understanding of readers’ value judgment of online medical information, demonstrates the importance of considering the congruence of content with contextual cues, and opens up exciting opportunities for future research to explore the role of content-context congruence in all varieties of user-generated content. Our findings also provide direct practical implications for knowledge contributors and Q&A sites.

    Does displaying positive emotions (e.g., joy) during a funding pitch help an entrepreneur gain more financial support? Past research has approached this question mostly by treating emotional displays as static and focusing on the overall or average levels of displayed emotions. However, emotional displays are temporally dynamic and more salient in some moments or phases than others. Drawing from gestalt characteristics and event system theories, we take a dynamic approach to examine the “peak” moments of entrepreneurs’ displayed joy—specifically, the strength and duration of peak displayed joy during different phases of a pitch. We analyzed data from over eight million frames in 1,460 pitch videos, using the latest facial expression analysis technology. The findings unveil the benefit of pitching with a greater level of peak displayed joy, especially during the beginning and ending phases of a pitch. Moreover, the amount of time an entrepreneur spends at the peak level of his or her displayed joy has an inverted U-shaped relationship with funding performance. This research highlights not only the importance of investigating emotion temporal dynamics in the interpersonal context, but also the unique research opportunities provided by facial expression analyses in understanding complex management phenomena.

    This research explores how expressed emotional arousal in a consumer review affects reader perceptions of its helpfulness. Drawing from research on written communication and lay theories of emotion, the authors propose a pattern of diminishing returns, in which the marginal effect of arousal on perceived helpfulness is positive at low levels of arousal but diminishes at higher levels. Results of a field study using Apple’s App Store, a follow-up survey, and two laboratory experiments provide consistent evidence for the predicted pattern. In addition, the results suggest that the nonlinear effect is explained in part by perceptions of reviewer effort and that the effect is stronger for products that are utilitarian in nature. By revealing a nuanced relationship between emotional expression and perceived helpfulness, these findings offer valuable implications for effective word-of-mouth communication.

  9. Yin, D., Mitra, S., & Zhang, H. (2016). When Do Consumers Value Positive vs. Negative Reviews? An Empirical Investigation of Confirmation Bias in Online Word of Mouth. Information Systems Research, 27(1), 131-144. [AbstractAbstract] [PDF]

    In the online word-of-mouth literature, research has consistently shown that negative reviews have a greater impact on product sales than positive reviews. Although this negativity effect is well documented at the product level, there is less consensus on whether negative or positive reviews are perceived to be more helpful by consumers. A limited number of studies document a higher perceived helpfulness for negative reviews under certain conditions, but accumulating empirical evidence suggests the opposite. To reconcile these contradictory findings, we propose that consumers can form initial beliefs about a product on the basis of the product’s summary rating statistics (such as the average and dispersion of the product’s ratings) and that these initial beliefs play a vital role in their subsequent evaluation of individual reviews. Using a unique panel data set collected from Apple’s App Store, we empirically demonstrate confirmation bias—that consumers have a tendency to perceive reviews that confirm (versus disconfirm) their initial beliefs as more helpful, and that this tendency is moderated by their confidence in their initial beliefs. Furthermore, we show that confirmation bias can lead to greater perceived helpfulness for positive reviews (positivity effect) when the average product rating is high, and for negative reviews (negativity effect) when the average product rating is low. Thus, the mixed findings in the literature can be a consequence of confirmation bias. This paper is among the first to incorporate the important role of consumers’ initial beliefs and confidence in such beliefs (a fundamental dimension of metacognition) into their evaluation of online reviews, and our findings have significant implications for researchers, retailers, and review websites.

  10. Yin, D., Bond, S. D., & Zhang, H. (2014). Anxious or Angry? Effects of Discrete Emotions on the Perceived Helpfulness of Online Reviews. MIS Quarterly, 38(2), 539-560. [AbstractAbstract] [PDF]

    This paper explores the effects of emotions embedded in a seller review on its perceived helpfulness to readers. Drawing on frameworks in literature on emotion and cognitive processing, we propose that over and above a well-known negativity bias, the impact of discrete emotions in a review will vary, and that one source of this variance is reader perceptions of reviewers’ cognitive effort. We focus on the roles of two distinct, negative emotions common to seller reviews: anxiety and anger. In the first two studies, experimental methods were utilized to identify and explain the differential impact of anxiety and anger in terms of perceived reviewer effort. In the third study, seller reviews from Yahoo! Shopping web sites were collected to examine the relationship between emotional review content and helpfulness ratings. Our findings demonstrate the importance of examining discrete emotions in online word-of-mouth, and they carry important practical implications for consumers and online retailers.
