评价顺序影响评分真实性，先打分更极端，后写评更集中。
Intuition First or Reflection Before Judgment? The Impact of Evaluation Sequence on Consumer Ratings
- 先打分再写评论，比先写评再打分更易导致极端评分。
- 高质量服务下先打分评分更高，低质量服务下则更低。
- 适合做平台界面设计优化，尤其对娱乐类商品更显著。
随着在线评论日益影响消费者决策，评论界面设计对评分真实性的影响力仍缺乏深入探讨。本研究通过三个实验和一项大规模二次数据分析，探究了评价顺序（“评分先行”与“评论先行”）对消费者评分的影响。结果揭示显著的极化效应：在高质量服务情境下，“评分先行”序列（相比“评论先行”）显著提高整体评分；而在低质量情境下，则导致明显更低的评分。这一机制由情感启发与认知努力的串行中介路径驱动。此外，产品属性起调节作用，享乐型产品比实用型产品放大评分两极化程度。来自Yelp和Letterboxd的二次数据验证了上述发现：采用“评分先行”模式的Yelp呈现极化的双峰分布，而“评论先行”的Letterboxd则显示更集中的评分分布。结论表明，从信息处理视角看，评价顺序通过情感与认知路径塑造消费者评分。该研究拓展了在线评论形成过程的理论理解，并为平台优化界面设计、提升评分真实性与可信度提供实践启示。
原文摘要 · Abstract (English)
As online reviews increasingly drive consumer decisions, the impact of review interface design on rating authenticity remains under-explored. This research investigates how evaluation sequence ("Rating-First" vs. "Review-First") influences consumer ratings through three experiments and a large-scale secondary data analysis. The results reveal a significant polarization effect: in high-quality service contexts, the "Rating-First" sequence (vs. "Review-First") increases overall ratings, whereas in low-quality contexts, it leads to significantly lower ratings. This mechanism is driven by a serial mediation path of affective heuristics and cognitive effort. Furthermore, product attributes moderate this effect, with hedonic products amplifying the rating extremity compared to utilitarian ones. Secondary data from Yelp and Letterboxd confirm these findings, showing that the "Rating-First" platform (Yelp) exhibits a polarized bimodal distribution, while the "Review-First" platform (Letterboxd) shows more concentrated ratings. In conclusion, this research reveals how evaluation sequence shapes consumer ratings through affective and cognitive paths from an information-processing perspective. These findings extend the theoretical understanding of the online review formation process and offer practical insights for platforms to optimize interface design and enhance rating authenticity and credibility.
