Diversity is based on the belief that some group‘s behavior patterns are fitting better with the environment, even temporarily and locally. But DEI is denying this difference, expecting any behavioral pattern should deserve the same result. They can’t even reach a logic consistency.
PS: I saw an academic department with unwitting ideological and morphological homogeneity that couldn't see their hiring and selection biases. It wasn't done with malice, but most PI's hired people who looked like them because the dept chair was so hands off that there was no leadership conferred, i.e., blinding resume or CV details. The dept chair was rarely in and basically just a salesman and occasional figurehead.
