We have discussed research on team diversity in race or gender. But what about diversity created by national differences? Like the earlier research, evidence here indicates these elements of diversity interfere with team processes, at least in the short term. 34 Cultural diversity does seem to be an asset for tasks that call for a variety of viewpoints. But culturally heterogeneous teams have more difficulty learning to work with each other and solving problems. The good news is that these difficulties seem to dissipate with time. Although newly formed culturally diverse teams underperform newly formed culturally homogeneous teams, the differences disappear after about 3 months. 35 Fortunately, some team performance-enhancing strategies seem to work well in many cultures. One study found that teams in the European Union made up of members from collectivist and individualist countries benefited equally from having group goals.
