Groups genuinely differ yet their member distributions overlap considerably

Evidence

As Campbell (1967) articulated, from an anthropological point of view, it is obvious that groups differ. They differ in their histories, customs, habits, preferences, values, traits, and goals. Of course, groups are themselves made up of diverse individuals, and certainly within groups there is considerable variability in those same characteristics along which groups differ from each other. Accordingly, while groups differ, undoubtedly distributions of group members show considerable overlap. — , Rudman, Laurie A - On the Nature of…, 846
