To play the devil's advocate, how do we know this carries over to business? If this was the case, it should have a track record at this point, since DEI has been a topic for a long time. Looking at comparable companies where one did do DEI and the other didn't, did one or the other have a statistically significant edge over the other? I have no idea, but I'm far from convinced purely from a reasoning stand point.

NPR had a story on this topic years ago and the researchers they talked with said diversity appears to have a negative impact on startups but a positive impact on established businesses. The logic was startups are smaller and need to move fast and be focused so DEI type efforts distract from the main business at that time. Once established diversity help the business by having people that can see business opportunities and challenges that a more homogenous workforce would not otherwise notice.

The current example is Target vs Costco.

(Because of a black pastor-led boycott of Target for dropping their DEI policy)
