The first link is behind a paywall so I couldn't access it.

The second link is some good research, demonstrating a correlation between diversity and profitability. I was hoping to find within it an analysis of possible confounding factors - for example, what if profitable companies can afford to initiate "diversity and inclusion" campaigns and institute quotas, which would turn the causality the other way around(higher profits -> more diversity), rather than the researchers' explanation(more diversity -> higher profits). Unfortunately there doesn't seem to be any such analysis in the paper.

Is this the full text of the third link? https://www.emeraldinsight.com/doi/pdfplus/10.1108/SHR-10-20...

The link is more of an article on what diversity and inclusion is, and how to measure its benefits, rather than research that shows those benefits.
