In organizational groups, expertise and information are often distributed among group members, thus making information sharing a necessity for group success. We examine the role of mood diversity on the discussion of disconfirming information and evaluation of decision alternatives in groups. In a laboratory experiment, using a hidden profile task, we manipulated mood diversity in 36 four-person, same-sex groups. Results indicated that mood diversity (vs. homogeneity) was positively related to groups’ focus on disconfirming information, which ultimately led to a more accurate evaluation of their decision alternatives. Results of the study expand our understanding of how mood composition of groups affects their discussion dynamics and decision evaluation.

在组织团体中，专业知识和信息通常分布在团体成员之间，因此信息共享成为团体成功的必要条件。我们研究了情绪多样性在讨论不确认信息和评估群体决策选择方面的作用。在实验室实验中，我们使用隐藏的个人资料任务控制了 36 个四人同性小组的情绪多样性。结果表明，情绪多样性（相对于同质性）与群体对否定信息的关注呈正相关，这最终导致对他们的决策选择进行更准确的评估。该研究的结果扩展了我们对群体情绪构成如何影响他们的讨论动态和决策评估的理解。
