Botan & Hazleton explain: "Citizens have particular images (or conceptions) of their own nation in relations to other nations, and those images reflect specific values and emotions. People in one nation make attributions about those living in other nations even when they have not visited a particular country. When individuals discuss their personal images with others, they contribute to the creation of public images. The public images of nation-states emanate from a “universe of discourse” (Boulding, 1956, p. 15)."
