Diversity does make a diff but it depends on the problem. Its sort of the Explore-Exploit trade off.

For Explore type problems diversity has a much bigger impact then Exploit type problems. To add to the drama/misunderstandings/confusion sometimes you assemble a team for explore and they do find the gold mine, but then they arent suited to exploit it cuz its in their nature to explore. And vice versa.
