nounC1GRESAT

formalinformal

An environment, especially on social media, where a person encounters only beliefs or opinions that coincide with their own, so that their existing views are reinforced and alternative ideas are not considered.

The term implies a self-reinforcing cycle where like-minded individuals communicate primarily with each other, leading to a lack of exposure to diverse perspectives and often an intensification of existing beliefs.

The story behind the word. The term 'echo chamber' literally refers to a room designed to produce echoes, often used in audio recording. Its metaphorical use in social and political discourse emerged in the early 2000s, gaining prominence with the rise of the internet and social media. It vividly describes how information and opinions bounce around within a closed group, amplifying and reinforcing themselves, much like sound waves in a physical chamber.
