Any evidence for this or is it just wishful thinking? The more diverse a group is the harder it is to communicate because of culture/language barriers. So it doesn’t seem to be obviously true to me.
The parent comment uses “seems” so doesn’t claim certainty. I attended a seminar by Amy Edmunson [0] that cited studies indicating that teams of higher diversity were slightly lower performing on average but had higher variance. The takeaway was that a route to a higher performing team was increased team diversity plus psychological safety can lead to improved results by keeping the top end of the variation range.
It doesn’t match my experience. The most successful teams I have worked on were not diverse at all. And the worst teams I have worked on were very diverse. It is hard enough to understand each other and communicate clearly in a team without also having to overcome language/culture barriers.
