The Baining—one of the indigenous cultural groups of Papua New Guinea—have the reputation, at least among some researchers, of being the dullest culture on earth. Early in his career, in the 1920s, the famous British anthropologist Gregory Bateson spent 14 months among them, until he finally left in frustration. He called them “unstudiable,” because of their reluctance to say anything interesting about their lives and their failure to exhibit much activity beyond the mundane routines of daily work, and he later wrote that they lived “a drab and colorless existence.” Forty years later, Jeremy Pool, a graduate student in anthropology, spent more than a year living among them in the attempt to develop a doctoral dissertation. He too found almost nothing interesting to say about the Baining, and the experience caused him to leave anthropology and go into computer science. Finally, however, anthropologist Jane Fajans, now at Cornell University, figured out a way to study them.
