To date, numerous research endeavors have documented both the positive and negative effects of racial diversity on numerous group-level performance outcomes. Indeed, a reading of the racial diversity literature would lead one to make one of two contradictory predictions regarding the effects of racial diversity in groups. In the interest of solving this theoretical issue, both perspectives were synthesized, such that racially diverse groups were expected to outperform homogeneous groups when performing a decision-making task, but only when relationship conflict between members was minimized. In addition, the association between racial diversity and decision-making quality was expected to be negative when relationship conflict between members was high. A study is reported which investigates the validity of and finds general support for this proposition (i.e., racial diversity in groups increased the group’s ability to make accurate decisions, but only under conditions in which relationship conflict between group members was kept to a minimum). A discussion is offered in which the implications of these results are entertained.

调查种族多样性对决策群体的影响：关系冲突的调节作用

迄今为止，许多研究工作已经记录了种族多样性对许多群体绩效结果的正面和负面影响。事实上，阅读种族多样性文献会导致人们对种族多样性对群体的影响做出两个相互矛盾的预测之一。为了解决这个理论问题，综合了两种观点，因此种族多样化的群体在执行决策任务时被期望优于同质群体，但前提是成员之间的关系冲突最小化。此外，当成员之间的关系冲突很高时，预计种族多样性与决策质量之间的关联为负相关。据报道，一项研究调查了这一主张的有效性并找到了普遍支持（即，群体中的种族多样性提高了群体做出准确决策的能力，但前提是群体成员之间的关系冲突保持在最低限度）。提供了一个讨论，其中考虑了这些结果的含义。
