The book was named after the 'naven' rite, an honorific ceremony among the Iatmul, still continued today, that celebrates first-time cultural achievements. The ceremony entails many antics that are normally forbidden during everyday social life. For example, men and women reverse and exaggerate gender roles; men dress in women's skirts, and women dress in men's attire and ornaments. Additionally, certain categories of female kin smear mud in the faces of other relatives, beat them with sticks, and hurl bawdy insults. Mothers may drop to the ground so their celebrated 'child' walks over them. And during a male rite, a mother's brother may slide his buttocks down the leg of his honoured sister's son, a complex gesture of masculine birthing, pride, and insult, rarely performed before women, that brings the honoured sister's son to tears. Bateson suggested the influence of a circular system of causation, and proposed that:  Women watched for the spectacular performances of the men, and there can be no reasonable doubt that the presence of an audience is a very important factor in shaping the men's behavior. In fact, it is probable that the men are more exhibitionistic because the women admire their performances. Conversely, there can be no doubt that the spectacular behavior is a stimulus which summons the audience together, promoting in the women the appropriate behavior. In short, the behaviour of person X affects person Y, and the reaction of person Y to person X's behaviour will then affect person X's behaviour, which in turn will affect person Y, and so on. Bateson called this the "vicious circle." He then discerned two models of schismogenesis: symmetrical and complementary. Symmetrical relationships are those in which the two parties are equals, competitors, such as in sports. Complementary relationships feature an unequal balance, such as dominance-submission (parent-child), or exhibitionism-spectatorship (performer-audience). Bateson's experiences with the Iatmul led him to publish a book in 1936 titled "Naven: A Survey of the Problems suggested by a Composite Picture of the Culture of a New Guinea Tribe drawn from Three Points of View" (Cambridge University Press). The book proved to be a watershed in anthropology and modern social science. Until Bateson published "Naven," most anthropologists assumed a realist approach to studying culture, in which one simply described social reality. Bateson's book argued that this approach was naive, since an anthropologist's account of a culture was always and fundamentally shaped by whatever theory the anthropologist employed to define and analyse the data.
