Spiral of silence theory says people speak up or go quiet based on their perception of public opinion—the climate of opinion—not just their own beliefs.
It starts with fear of isolation (being socially left out) and relies on a quasi-statistical sense (an informal mental tally) that estimates whether one’s view is the majority or minority on a divisive issue of public interest. If a view seems popular or gaining ground, people voice it; if it seems unpopular or losing ground, they self-censor.
This imbalance in who talks creates a positive feedback loop: the active side is heard more, appears larger than it is, gets more exposure, and solidifies into a social norm (a shared “right way” to speak or act), while the quieter side seems smaller and retreats further.
The process works at the micro level (individual willingness to express) and the macro level (shifts in the overall opinion climate), with public opinion acting as social control—things you can say without risking social sanctions.
Mass media amplify this via agenda-setting (highlighting issues) and by portraying a dominant view that can become the status quo; predictions about “where opinion is headed” can become self-fulfilling.
Some resist—hardcore nonconformists or a vocal minority who don’t fear isolation—so change can still start from the margins. Perceptions can be wrong (pluralistic ignorance), so a view many privately reject can look like the norm.
Online, the same dynamics appear: social feedback can prompt self-censorship, vocal minorities may still speak, and even artificial boosts can inflate apparent support and nudge the spiral.
