內(nèi)容簡介：
This research examines negativity bias in the formation of trust by online consumers evaluating peer information regarding potential sellers. Drawing on research from social perception, the authors propose that negative reviews are not always more influential than positive ones: although online consumers should be biased towards negative content when evaluating information concerning sellers’ integrity, the bias should be reduced for information concerning sellers’ competence. In two experiments, participants were provided text reviews (Study 1) or ratings (Study 2) of sellers in typical online settings, and then asked to provide evaluations of seller trustworthiness. As predicted, negative word-of-mouth was not always stronger than positive in trust formation; instead, the magnitude of the bias depended on the type of seller information encountered. These findings challenge the traditional wisdom of a universal negativity bias and contribute to current understanding regarding the development of consumer trust.
