Can you point us to such documentation?  It would be nice to know under

https://hbr.org/2016/11/why-diverse-teams-are-smarter includes links to several studies. There are a lot more results as well to the search “diverse teams make better decisions” or “diverse groups decision making” on Google as well if those studies are lacking to you.
