Step 1: Understanding the Concept:
This theory explains how public opinion is formed and why people sometimes withhold their opinions.
Step 2: Detailed Explanation:
The Spiral of Silence theory was proposed by German political scientist Elisabeth Noelle-Neumann in 1974.
It suggests that individuals have a fear of isolation.
When they perceive that their opinion is in the minority or losing popularity, they remain silent to avoid social rejection.
As the dominant view is expressed more and the minority view less, it creates a "spiral" effect where the majority view seems even more dominant than it might actually be.
Step 3: Final Answer:
Elisabeth Noelle-Neumann is the developer of this theory.
