How rejected recommendations shape recommenders' future product intentions
研究发现，当推荐者得知自己的推荐被拒绝后，他们未来购买或选择该产品的意愿会降低，原因是自我感知的专业知识受到质疑，且该效应在推荐对象为亲近者时更显著。
Abstract When a consumer (a recommender) recommends a product to another consumer (a recommendee), it is not uncommon to learn whether the recommendee chose the recommended option (i.e., accepted the recommendation) or a different option (i.e., rejected the recommendation). Our research examines how rejected recommendations affect recommenders' subsequent intentions toward the originally recommended product. We find that upon learning one's recommendation was rejected, recommenders are less likely to repurchase or choose the product in the future. This negative effect emerges because recommenders question their knowledge about the recommended product (i.e., self‐perceived expertise is reduced). Such questioning is more likely to occur when the recommendee is a close other and less likely to occur when the recommended product is perceived to primarily differ from alternatives due to subjective preferences (i.e., horizontal differentiation is salient). Importantly, this rejected recommendation effect is shown to be distinct from a social proof account. The current research contributes to WOM theory by identifying a novel outcome of recommendation interactions—rejected recommendations—and by demonstrating that this outcome can cause consumers to shift away from a product despite having felt positively enough about the product to recommend it to others.
