Spiral of silence
The spiral of silence theory is a political science and mass communication theory which states that an individual's perception of the distribution of public opinion influences that individual's willingness to express their own opinions. Also known as the theory of public opinion, the spiral of silence theory claims individuals will be more confident and outward with their opinion when they notice that their personal opinion is shared throughout a group. But if the individual notices that his opinion is unpopular with the group he will be more inclined to be reserved and remain silent. In other words, from the individual's perspective, "not isolating himself is more important than his own judgement", meaning his perception of how others in the group perceive him is more important to himself than the need for his opinion to be heard.According to Glynn (1995), "the major components of the spiral of silence include (1) an issue of public interest; (2) divisiveness on the issue; (3) a quasi-statistical sense that helps an individual perceive the climate of opinion as well as estimate the majority and minority opinion; (4) 'fear of isolation' from social interaction "(though, whether this is a causal factor in the willingness to speak out is contested)"; (5) an individual's belief that a minority (or 'different') opinion isolates oneself from others; and (6) a 'hardcore' group of people whose opinions are unaffected by others' opinions. "The theory is not without criticism, some arguing that its widely understood definition and parameters have not been updated to reflect the behavior of 21st century society.
