What you are describing is a bias. You are suggesting we should be bias towards believing a metric is wrong if it disproportionally affects a protected category. One would also assume that if we have it specify “protected category” that we should believe metrics are right even if they negatively affect those in unprotected categories. That’s a political calculation not a logical one. Also in practice members of protected groups who are over represented at a specific business can be disproportionately subject to layoffs to ensure the protection of less represented minorities. The general bias is toward integrating businesses and favouring protected classes for better or for worse.
