A semantic cocoon refers to the personalized and often isolated digital environment created by algorithms and data collection, which tailors information and content to an individual’s preferences and beliefs. This cocoon can limit exposure to diverse perspectives and ideas, leading to a narrow and biased understanding of the world. It can also reinforce and amplify existing beliefs, creating an echo chamber effect. The term highlights the potential negative consequences of living in a highly curated and filtered online world, where the individual’s perception of reality may be distorted and disconnected from the larger societal context.
