Xenocentrism was coined by American sociologists Donald P. Kent and Robert G. Burnight in the 1952 paper "Group Centrism in Complex Societies" published in the American Journal of Sociology [REF].
The term is opposed to ethnocentrism, as coined by 19th-century American sociologist William Graham Sumner, which describes the natural tendencies of an individual to place disproportionate worth upon the values and beliefs of one's own culture relative to others [REF].
