user anthropologist
n.— «He’s also sometimes referred to as a “user anthropologist.” To an outsider, the job can seem decidedly oblique. His mission, broadly defined, is to peer into the lives of other people, accumulating as much knowledge as possible about human behavior so that he can feed helpful bits of information back to the company—to the squads of designers and technologists and marketing people who may never have set foot in a Vietnamese barbershop but who would appreciate it greatly if that barber someday were to buy a Nokia.» —“Can the Cellphone Help End Global Poverty?” by Sara Corbett New York Times Apr. 13, 2008.
