This research examines gossip as a facilitator of reputational social exchange, and shows that exposure to gossip moderates the social influence of product endorsement. Participants read positive and negative gossip about different endorsers, and event-related potentials (ERPs) were recorded during product endorsement. Behavioral results indicate that gossip about a close friend or celebrity (relative to a stranger) and positive (vs. negative) gossip increase consumer willingness-to-pay following product endorsement respectively. ERP results reveal two distinct ERP components following exposure to gossip. During the late stage (350–500 ms) of product endorsement, exposure to gossip about a close friend (relative to celebrity or a stranger) and negative (relative to positive) gossip each elicited a distinctively larger N400 response. During the later stage (500–700 ms), positive (versus negative) gossip elicited a larger LPP during friend endorsement relative to celebrity endorsement. The findings illustrate the motivational significance of gossip about friends from a social learning perspective. We also discuss the marketing implications for friend e...
