The end product of anthropological research, if properly carried out, is a coherent statement about a people that provides an explanatory framework for understanding the beliefs, behavior, or biology of those who have been studied. And this, in turn, is what permits the anthropologist to frame broader hypotheses about human beliefs, behavior, and biology. A single instance of any phenomenon is generally insufficient for supporting a plausible hypothesis. Without some basis for comparison, the hypothesis grounded in a single case may be no more than a particular historical coincidence. On the other hand, a single case may be enough to cast doubt on, if not refute, a theory that had previously been held to be valid. For example, the discovery in 1948 that Aborigines living in Australia’s northern Arnhem Land put in an average workday of less than
6 hours, while living well above a bare-sufficiency level, was enough to call into question the widely accepted notion that food-foraging peoples are so preoccupied with finding scarce food that they lack time for any of life’s more pleasurable activities.
The observations made in the Arnhem Land study have since been confirmed many times over in various parts of the world.
To test hypothetical explanations of cultural and biological phenomena, researchers compare data gathered from several societies found in a region; these data are derived from a variety of approaches,
Including archaeology, biology, linguistics, history, and ethnography. Carefully controlled comparison provides a broader basis for drawing general conclusions about humans than does the study of a single culture or population.
Ideally, theories in anthropology are generated from worldwide comparisons or comparisons across species or through time. The cross-cultural researcher examines a global sample of societies in order to discover whether hypotheses proposed to explain cultural phenomena or biological variation are universally applicable. The crosscultural researcher depends upon data gathered by other scholars as well as his or her own. These data can be in the form of written accounts, artifacts and skeletal collections housed in museums, published descriptions of these collections, or recently constructed databases that allow for cross-species comparisons of the molecular structure of specific genes or proteins.
