In recent years the attention towards demographic diversity has increased among academics and practitioners dealing with organization management. Finding a possible connection between diversity and group performance has been the objective of much extant research. Still, however, results are inconclusive. Based on a sample consisting of 489 members of multicultural academic departments, we set out to examine the relationship between diversity climate (group openness to linguistic, visible, value, and informational diversity), and performance (perceived group performance, group satisfaction). We found openness to linguistic, value, and informational diversity to have strong positive associations with perceived group performance and group satisfaction. Implications of the findings are discussed in detail.
