Full disclosure, I haven't had time to vet the individual studies cited, but this article could be a good starting point to investigate this idea. Be sure to at least look at the second half, where they move from correlation to causation: https://www.scientificamerican.com/article/how-diversity-makes-us-smarter/ https://www.scientificamerican.com/article/how-diversity-mak... Here's the paragraph I want to highlight: "Members of a homogeneous group rest somewhat assured that they will agree with one another; that they will understand one another's perspectives and beliefs; that they will be able to easily come to a consensus. But when members of a group notice that they are socially different from one another, they change their expectations. They anticipate differences of opinion and perspective. They assume they will need to work harder to come to a consensus. This logic helps to explain both the upside and the downside of social diversity: people work harder in diverse environments both cognitively and socially. They might not like it, but the hard work can lead to better outcomes."
