Information cocoon and selective forgetting: a study on the effect of propaganda desensitization based on push mechanism

摘要: Under the algorithmic mechanism, the audience's long-term exposure to homogenous content will cause a certain degree of cognitive dissonance. However, long-term exposure to certain information may also cause a decline in the audience's understanding of the importance of the information, resulting in a desensitization effect. Based on the observation of the audience's desensitization to epidematic-related information during the epidemic, this paper uses the questionnaire survey method to collect data, and conducts cross-analysis to draw the following conclusions: First, on the whole, the more audiences are exposed to certain propaganda, the more important they believe it to be Secondly, there is a certain inflection point when the audience is in contact with the propaganda content. When a certain inflection point is reached, the greater the amount of propaganda, the less sensitive the audience is to the information. Three reasons for this phenomenon are proposed: reducedfear appeal shockof entertainment information and long-term exposure to numbness.
