I general support workplace diversity and mechanisms to promote it but you're making it sound like it's settled science based on some PR piece by a consulting firm promoting a a white paper that almost certainly wasn't rigorous enough to meet any reasonable standards - how do you properly control for confounding factors and how do you define "better" decision? That's miles away from being published in a peer-reviewed journal, which in isolation is also miles away from settled science. This is a microcosm of the political climate we're in - we're too eager to accept what we want to believe, while setting impossible standards for claims that we're disinclined to believe.
