The affective consequences of diversity and homogeneity in groups

Understanding the impact of diversity on group process and performance has been the focus of much research, yet there are still unanswered questions about how diversity impacts group process and performance. One factor that is clearly a consequence of group composition is affective tone. In this chapter, we discuss the impact of diversity and homogeneity on affective responses from group members and argue that the relatively negative affective tone experienced in diverse groups may fuel more systematic information processing and improve decision-making performance. The implications for managing both positive and negative affect in groups will be considered.
