ItemWhat Makes Consumer Perception of Online Review Helpfulness: Synthesizing the Past to Guide Future Research( 2021-01-05)A growing body of academic research has aimed to investigate the helpfulness of online customer reviews (OCRs) given their prevalence and the need to better understand their appraisal mechanisms. However, past studies have applied varied methods and reported conflicting findings. This study aims to improve the understanding of the contributors to OCR helpfulness by synthesizing past studies on the topic. Based on a systematic literature review, a summary of the precursors to OCR helpfulness is provided. We decipher both the consistent and conflicting results and discuss the possible explanations for these mixed findings. By summarizing past studies, the review also points out possible directions for future research.
ItemThe Role of Social Media Normative Interventions and Environmental Awareness in Intentions to Change Pro-Environmental Behaviors( 2021-01-05)Social media interventions to stimulate the adoption of pro-environmental behaviors is a topic of increasing interest in both Information Systems (IS) research and environmental studies. Yet, we still know little about the factors explaining the effectiveness of such interventions and how they influence decision-making in online social networks. By bringing together insights from both social science and IS research streams, this research-in-progress studies intentions to change towards pro-environmental behaviors as the results of exposure to normative social media content and the level of environmental awareness. We conducted an online experiment to explore intentions to change behaviors regarding the consumption of meat. We find that while individual environmental awareness is positively associated with intentions to change meat consumption, exposure to social norms in social media content is not significant in predicting intentions to change meat consumption. Since our findings suggest the importance of environmental awareness in decision-making towards sustainable behaviors, our future research will explore the inclusion of information provision to stimulate environmental awareness in combination with nudging on social media.
ItemTell me the Truth: Separating Fact from Fiction in Social Media Following Extreme Events( 2021-01-05)With increased reliance on social media to spread important information during extreme events, users’ reported inability to distinguish fact from fiction is a growing concern. This experiment (N=398) tests whether feedback training improves performance in identifying true and false social media content during extreme events. Respondents completed two sets of 16 binary classification judgments (true or false) of actual social media posts following either natural disasters or soft-target terror attacks. Respondents randomly assigned to the feedback training condition received feedback after each of the 16 training judgments, while those assigned to the control condition did not receive any feedback following the training judgments. Feedback training did not increase social media content classification performance for either natural disasters or soft-target terror events. Individuals’ performance for correctly identifying false content was negatively related to self- identified political conservatism and was positively related to a measure of cognitive reflection.
