Goldstein和Gigerenzer（2002）[生态理性模型：识别启发式。Psychological Review，109（1），75-90]发现了使用识别启发式的证据。例如，如果一个人只认出两个城市中的一个，他们往往会推断出这个城市的人口更多。接下来的预测是“少即是多”效应：在某些条件下，识别更少的城市比识别更多的城市更能导致更准确的推断。我们扩展了识别启发式群决策的开发多数和词典模型识别信息是如何使用的群体。我们正式表明，当少即是多的效果预测组，我们提出了一项研究，其中三人组进行人口比较任务。我们的数据的几个方面表明，成员谁可以使用识别启发式，而不是在所有的，但在大多数情况下，更有影响力的群体决策过程中的成员谁不能使用启发式。我们还观察到了“少即是多”效应，并发现假设能够使用识别启发式的成员更有影响力的模型可以更好地预测效应何时发生。(C)2004年认知科学学会All rights reserved.
Goldstein and Gigerenzer (2002) [Models of ecological rationality: The recognition heuristic. Psychological Review, 109 (1), 75-90] found evidence for the use of the recognition heuristic. For example, if an individual recognizes only one of two cities, they tend to infer that the recognized city has a larger population. A prediction that follows is that of the less-is-more effect: Recognizing fewer cities leads, under certain conditions, to more accurate inferences than recognizing more cities. We extend the recognition heuristic to group decision-making by developing majority and lexicographic models of how recognition information is used by groups. We formally show when the less-is-more effect is predicted in groups and we present a study where three-member groups performed the population comparison task. Several aspects of our data indicate that members who can use the recognition heuristic are, not in all but in most cases, more influential in the group decision process than members who cannot use the heuristic. We also observed the less-is-more effect and found that models assuming that members who can use the recognition heuristic are more influential better predict when the effect occurs.
