Analysis of the Echo Chamber Caused by Unexpected Opinions.

Recently, with the widespread use of social media, the speed of information dissemination has significantly increased. As a result, users have started selectively consuming information, leading to a bias in information consumption. One prominent phenomenon of information consumption bias is the echo chamber effect. While the social impact of the echo chamber effect is diverse, notable instances include its influence on health and politics. These cases highlight situations not adequately captured by the conventional definition of the echo chamber effect. In response, this study proposes a new definition of echo chambers, aiming to explore instances where opinions are not only reinforced but also undergo changes.To substantiate this proposal, the study employs specific verification methods. It investigates differences in the distribution of singularity at points of opinion reinforcement and change. Additionally, it explores variances in the emotional impact of video content and the distribution of echo chamber scores. The findings demonstrate that echo chambers occur not only when opinions are reinforced but also when they undergo changes. The newly proposed definition of the echo chambers suggests a situation where individuals immerse themselves in opinions that pique their interest, regardless of their own thoughts, resulting in a feedback loop of reinforcing and potentially changing perspectives.
