Understanding Our Differences: Performance in Decision-Making Groups with Diverse Members
构建了一个模型，解释成员高度多样化的决策小组的绩效，发现多样性若被整合可提升绩效，并提出沟通作为整合机制。
The purpose of this article is to develop a model to explain performance in decision-making groups characterized by high diversity in composition. It begins with a brief discussion on the nature and effects of diversity. Previous research on group performance is then reviewed with the general conclusion that diverse groups perform less well than homogeneous ones do. This conclusion is challenged by closely examining a small group of studies specifically researching the effects of diversity, and it is shown that diversity can enhance a group's performance if it is integrated. Communication is proposed as an integrating mechanism, and a theory of communication in terms of preconditions is described. This theory is then used to develop propositions concerning the relationships among diversity, integration, and performance in decision-making groups. Implications for research and practice are discussed.
