What does the term 'Availability Cascade' refer to?

The term 'Availability Cascade' refers to a self-reinforcing belief system that emerges as a result of information being repeatedly encountered. This phenomenon occurs when a particular idea becomes more widely accepted and considered credible due to its frequent mention and the availability of that information in public discourse. As individuals hear the same narrative repeatedly, it gains traction and legitimacy, making it more likely that others will adopt this belief, regardless of its actual validity.

This concept emphasizes the way in which collective belief can be shaped by the repetition of ideas in social contexts or media, leading to a snowball effect where an opinion becomes increasingly entrenched over time. It illustrates how our perceptions can be influenced by the sheer availability of information rather than the quality or accuracy of that information.
