The anthropologist Sarah Blaffer Hrdy argued that a reading of "On Human Nature" refutes the accusation that Wilson aims to use sociobiology to reinforce traditional sex roles. The philosopher Roger Scruton criticized Wilson's sociobiological explanations of human social behavior, arguing that because of Wilson's "polemical purpose" he was forced to oversimplify the facts. However, he granted that sociobiological explanations of the sort favored by Wilson might possibly be correct. The anthropologist Donald E. Brown commented that he at first failed to read Wilson's book because his views were still conditioned by the "sociocultural perspectives" in which he had been trained. However, Brown concluded that "sociobiologists might be more convincing if they confined their explanations to universals rather than attempting to show that virtually everything that humans do somehow maximizes their reproductive success."
