The present study examined how children change their evaluations when firsthand observations conflict with gossip. A total of 192 children aged four to six years participated in two experiments. Study 1 investigated the effects of age and gossip valence. Results showed that older children (five‐ and six‐year‐olds) were more likely than younger children (four‐year‐olds) to change their evaluations based on firsthand evidence when it contradicted gossip. In addition, evaluations based on negative gossip were more likely to change than those based on positive gossip. Study 2 further examined the role of the gossiper's intent. When children were informed of the gossiper's personal motives, they were more likely to rely on their own observations, and this effect surpassed both age and gossip valence. Together, these findings demonstrate that children's evaluation shifts are shaped by age, gossip valence, and the perceived intent of the gossiper. This study provides empirical support for enhancing children's ability to critically evaluate information and to cultivate more rational social cognition.\n\n\nSummary\n\nOlder children were more likely than younger children to revise their gossip‐based social evaluations after firsthand observation.\nChildren who initially received negative gossip were more likely to change their evaluations after observation than those who received positive gossip.\nCompared to behavior predictions, children's moral judgments about the gossip target were more resistant to change.\nKnowledge of the gossiper's intent significantly promoted children's reliance on firsthand observation to revise their evaluations.\n\n\n"]
