James Averill, a major proponent of social constructivism, describes a behavior pattern, called “being a wild pig”, that is quite unusual by Western standards, but is common and even “normal” among the Gururumba, a horticultural people living in the highlands of New Zealand. The behavior gets its name by analogy. There are no undomesticated pigs in this culture, but occasionally, and for unknown reasons, a domesticated one will go through a temporary condition in which it runs wild. But the pig can, with appropriate measures, be redomesticated and returned to the normal pig life among the villagers. And, in a similar vein, Gururumba people can act this way, becoming violent and aggressive and looting and stealing, but seldom causing harm or taking anything of importance, and eventually returning to routine life. In some instances, after several days of living in the forest, during which time the stolen objects are destroyed, the person returns to the village spontaneously with no memory of the experience and is never reminded of the event by the villagers. Others, though, have to be captured and treated like a wild pig - held over a smoking fire until the old self returns […]
Averill uses “being a wild pig” to support his claim that “most standard emotional reactions are socially constructed or institutionalized patterns of response” rather than biologically determined events.
