Confidence via correction: The effect of judgment correction on consumer confidence
研究发现，当产品推荐来自低可信度来源时，消费者修正判断反而会增强信心，进而提高购买意愿；而高可信度来源下修正会降低信心。该效应在高思考消费者中减弱。
Abstract At times, consumers are motivated to reduce the influence of a product recommendation on their judgments. Based on previous research, it is unclear whether this correction process will increase or decrease consumers' confidence in their judgments. We find that source credibility moderates the effect of correction on confidence: correction decreases confidence when a product recommendation comes from a high credibility source but increases confidence when the same message comes from a low credibility source. As a result, correction increases the effectiveness of recommendations from low credibility sources on purchase intentions. Notably, this “confidence via correction” effect is further moderated by elaboration, such that the effect is attenuated for high elaboration consumers. Our results have implications for understanding consumers' reactions to persuasive messages and for both marketing practitioners and consumer protection agencies using correction cues to influence message persuasiveness.
