AI生成的摘要日益成为人们在各平台解读信息的媒介，包括电商网站上的产品评论。以亚马逊的AI摘要为案例，我们开展了一项预注册的随机实验（N=278），比较AI摘要与用户评论如何塑造产品感知，以及其影响力如何随效价和呈现顺序而变化。我们发现，AI摘要和用户评论均能影响参与者的观点，且负面摘要的影响大于正面摘要。呈现顺序是最关键的因素：第一个来源锚定了判断，且只有用户评论能够取代已有的锚点。尽管参与者表示更偏好用户评论，但他们往往低估了AI摘要对其判断的影响。我们的研究结果表明，AI摘要的放置位置如何塑造用户感知，并凸显了设计界面的机会，以支持用户在何时依赖摘要、何时直接审视底层内容方面做出更审慎的判断。
英文摘要
AI-generated summaries increasingly mediate how people interpret information across platforms, including product reviews on e-commerce sites. Using Amazon's AI summaries as a case study, we conducted a preregistered, randomized experiment (N = 278) comparing how AI summaries and user reviews shaped product perceptions, and how their influence varied with valence and presentation order. We found that both AI summaries and user reviews influenced participants' opinions, with negative summaries having a larger effect than positive ones. Presentation order was the most important factor: the first source anchored judgment and only user reviews could displace an existing anchor. Although participants reported preferring user reviews, they often underestimated the influence of AI summaries on their judgments. Our findings show how the placement of AI summaries shapes user perception and highlight opportunities to design interfaces that support more deliberate judgments about when to rely on summaries and when to examine the underlying content directly.
