Ringkasan	The spiral of silence survey operationalizes Elisabeth Noelle-Neumann's 1974 theory that people who perceive their opinion to be in the minority grow reluctant to express it for fear of social isolation, which makes the apparent majority seem ever stronger — a self-reinforcing spiral. The method measures individuals' own opinions, their perception of the opinion climate, their fear of isolation, and their willingness to speak out, then models how these combine.	Media system dependency analysis operationalizes Ball-Rokeach and DeFleur's 1976 theory that media effects are strongest when individuals depend heavily on the media system to attain personal goals — understanding their world, orienting their actions, and finding diversion. The method surveys the intensity of these dependency relations and relates them to cognitive, affective, and behavioral effects of media.
