Hallpike said Rushton's theory failed to take into account that many other traits, ranging from age, sex, social and political group membership, are observably more important in predicting altruistic behavior between non-kin than genetic similarity, and John Hartung criticized him for failing to conduct an adequate control group study and for ignoring contradictory evidence.
