I don't think that's actually been "shown," it's more of an axiom that's assumed to be true without proof. IIRC, the idea that "[sex/race] diversity leads to better team outcomes" may even just be an idea meant to mainly lend legal cover to diversity efforts (e.g. university affirmative action race-based admissions) that would otherwise be illegal.

As much as I personally have read on this it's not blanket "diversity", or even "diversity of opinions", but rather quite strictly "diversity of viewpoints/perspectives". You know, like for example when we design urban environments we consider residents, pedestrians, cyclists, disabled and what not.
