Expert Measurement and Mechanical Combination in Control Reliance Decisions.
检验了Einhorn的“专家测量与机械组合”方法在控制依赖决策中消除偏差、提高共识的效果。该方法由人测量线索值，再通过数学模型组合成整体判断，减少了人整合信息时的错误。实验表明，机械组合的判断比整体判断更接近专家意见且更一致。
Abstract ABSTRACT: The ability of Einhorn's [1972] "expert measurement and mechanical combination" to eliminate bias and increase consensus in control reliance decisions was examined. This method uses the human to measure cue values end then combines these component judgments with a mathematical model to form global control reliance decisions. Its aim Is to eliminate error Induced when the human aggregates Information into a global judgment. Two groups of senior auditors evaluated a series of cases by either making global control reliance decisions or making component judgments of the strength of the individual controls end compliance tests. Component judgments of the latter group were combined mechanically into an overall Judgment. The mechanically combined component judgments were, on average, more like those provided by a group of firm experts and ware more consensual than the global judgments. These results are compared to those of prior studies which examined similar aids.
