Rituals that induce pain or instill fear occur in the majority of boys’ adolescent initiation ceremonies. They have been accounted for in several ways: as resolving a psychological conflict, as expressing dominance over juniors, as promoting male bonding, and as preparation for participation in war. This cross-cultural study examines these harsh rituals and concludes that they are a form of adult male control over adolescent boys and unmarried (sub-adult) youths. They occur in societies in which control over young males is an important social issue and other means of control are lacking. We also examine a subset of harsh rituals, those that include circumcision and other genital operations, and discuss the cultural features, particularly marriage practices, that are significantly associated with these operations.
