群体应该如何做出决策？作者提供了一个原始的评估9群决策规则的基础上，他们在模拟试验台环境中的自适应成功。当应用自适应成功标准时，多数和复数规则表现得相当好，其表现水平可与资源需求更高的规则（如个体判断平均规则）相媲美。多数规则匹配计算要求孔多塞多数赢家是标准的优先选择的评估。作者还测试了他们的理论分析的结果，在名义人类群体决策的行为研究，并证实了经验的基本发现。本研究的结论支持多数和多元规则在寻求真相的群体决策中的普遍性。
How should groups make decisions? The authors provide an original evaluation of 9 group decision rules based on their adaptive success in a simulated test bed environment. When the adaptive success standard is applied, the majority and plurality rules fare quite well, performing at levels comparable to much more resource-demanding rules such as an individual judgment averaging rule. The plurality rule matches the computationally demanding Condorcet majority winner that is standard in evaluations of preferential choice. The authors also test the results from their theoretical analysis in a behavioral study of nominal human group decisions, and the essential findings are confirmed empirically. The conclusions of the present analysis support the popularity of majority and plurality rules in truth-seeking group decisions.
