I agree that looking at group differences is the wrong thing to do. We should be looking at individuals as measured, as much as possible, by objective standards. But tell that to government, the media, academia, etc, which are utterly obsessed with group differences and which zealously insist that all such differences be eliminated. Even small group differences at the median can produce very large group differences two or three standard deviations out along the left or right tail of the Bell curve. If we focus on individuals and insist on a level playing field, that’s not a problem. For the race and gender wokesters, nothing else matters.
Too many lawyers and too many sociologists! ;)
