Decision Making Using Rating Systems: When Scale Meets Binary
研究了决策者参考二元评分系统和量表评分系统时可能得出不同决策结果，发现只有奇数且不被4整除的N点量表与二元系统在个体层面一致，但总体层面仍存在不一致，并提供了判断两者是否导向相同决策结果的简单工具。
ABSTRACT This article investigates how different decisions can be reached when decision makers consult a binary rating system and a scale rating system. Since typically decision makers use rating information to make binary decisions, it is particularly important to compare the scale system to the binary system. We show that the only N ‐point scale system that reports a rater's opinion consistently with the binary system is one where N is odd and is not divisible by 4. At the aggregate level, however, we illustrate that inconsistencies persist regardless of the choice of N . In addition, we provide simple tools that can determine whether the systems lead decision makers to the same decision outcomes.
