What is the self-reinforcing process where a belief gains plausibility through repetition in discourse?

The self-reinforcing process where a belief gains plausibility through repetition in discourse is known as an availability cascade. This phenomenon occurs when ideas or beliefs become more accepted simply because they are frequently repeated in public discourse. As individuals encounter the same idea over and over, it becomes more familiar and appears more plausible, influencing people's perceptions and behaviors. This can occur in various contexts, such as media coverage or social conversations, where the repetition of a belief enhances its perceived validity, and thus, promotes its acceptance within a larger group.

While emotional intelligence relates to the ability to recognize and manage one’s own emotions and those of others, groupthink is concerned with group decision-making processes that discourage individual creativity or responsibility. Transactive memory pertains to how groups store and retrieve information collectively, which is not directly connected to the reinforcement of belief through repetition. These distinctions clarify why the concept of an availability cascade aptly describes the process outlined in the question.
