Because of increased concern with political socialization, a study was designed to determine the sources high school students used in acquiring certain international orientations, specifically on peace and war. Subjects filled out a questionnaire on their beliefs and indicated what sources they thought had most influenced their thinking on these subjects. The primary media or sources for acquiring views on the concepts of war and peace, the causes and prevention of war, the morality of war, and the possibilities of avoiding war were identified by correlation. An overview of the results showed that the mass media, especially television, newspapers, and magazines, were most influential. Other sources, ranked from higher to lower in terms of influence, were: peer group, school experiences, family, and religion. The importance of a source differs according to whether concepts of war and peace, causes of war, prevention of war, or moral judgment of war is the orientation measured. (JK)
