DUAL‐METRIC MEASUREMENT OF THE IMPACT OF COMPLEXITY ON DECISION QUALITY*
通过双指标方法测量决策者内部一致性和跨项目方差，发现复杂性与决策质量负相关，但专业决策者在复杂任务中表现更好，非专业者在简单任务中表现更好，支持决策者与任务匹配的重要性。
ABSTRACT Both sophisticated and unsophisticated subjects were provided either a simple or a complex cue set at random on which to base decisions. A dual‐metric approach that consisted of measuring interrater consistency and cross‐item variance for each subject category was used to compare the decision quality of the subjects. Although complexity and decision quality were inversely related, the sophisticated subjects performed relatively better using the complex cue set; the unsophisticated subjects performed better using the simple cue set. These findings support the notion that decision‐maker and task compatibility are important to the assessment of decision quality.
