National psychology refers to the (real or alleged) distinctive psychological make-up of particular nations, ethnic groups or peoples, and to the comparative study of those characteristics in social psychology, sociology, political science and anthropology.
The assumption of national psychology is that different ethnic groups, or the people living in a national territory, are characterized by a distinctive "mix" of human attitudes, values, emotions, motivation and abilities which is culturally reinforced by language, the family, schooling, the state and the media.
