สรุป	The third-person effect survey measures W. Phillips Davison's 1983 observation that people tend to believe persuasive media messages affect other people more than themselves. The perceptual component documents this self–other gap, while the behavioral component tests whether the gap leads people to support censorship, corrective action, or other responses aimed at protecting the supposedly more-influenced others.	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.
