The spiral of silence theory is a political science and mass communication theory proposed by the German political scientist Elisabeth Noelle-Neumann, which stipulates that individuals have a fear of isolation, which results from the idea that a social group or the society in general might isolate, neglect, or exclude members due to the members' opinions. This fear of isolation consequently leads to remaining silent instead of voicing opinions. Media is an important factor that relates to both the dominant idea and people's perception of the dominant idea.
