This study deals with the industrial use of those disciplines which are primarily and directly concerned with human thought and conduct in the widest sense and which do not emphasize particular aspects of human experience. Thus by "social science" is meant only psychology, sociology, occasionally anthropology, and the new field of human relations. Other social sciences, for example economics and political science, become relevant at a very few points and are dealt with when necessary.—Print ed.
