Spiral of Silence

Definition: Spiral of Silence is a 1984 model by Noelle-Neumann that explains why people are unwilling to express their opinions in public when they believe that they are in the minority. The SoS concept is based on three assumptions:
- People have a "quasi-statistical organ", a sixth-sense, which allows them to know the prevailing public opinion. Even without access to polls.
- People have a fear of isolation and know what behaviors will increase the likelihood of being socially isolated.
- People are reticent to express their minority views. Primarily out of fear of being isolated.
Related to Groupthink. Can be countered by using 6 Thinking Hats.
