讲座题目：《Likely to be Real Unless It is Positive: Truth Bias, Veracity Effects, and the Role of Valence in Perceptions of Online Reviews 》，co-authors: Dezhi Yin, Samuel D. Bond, and Han Zhang.
讲座摘要: In contrast to a growing stream of research in IS and related fields on the automated detection of “fake” online reviews, little is known about whether and why consumers trust reviews of unknown veracity. We explore the extent to which consumers perceive reviews as real (versus fake), the accuracy of those perceptions, and how they are influenced by review valence. Integrating literature on truth-default theory and deception motives, we propose that consumers have a general tendency to view reviews as real rather than fake (a truth bias) and are more accurate at detecting real reviews than fake reviews (a veracity effect), but that the truth bias and veracity effect are weaker for positive reviews than negative reviews. To test our hypotheses, we conducted five experiments in which participants were shown a set of reviews and classified each review as real or fake. The results supported our theorizing and identified the perception of deception motives as an important process mechanism. Our findings offer important implications for firms and review platforms as they establish priorities for combating fake reviews.
