“An information (or informational) cascade occurs when a person observes the actions of others and then—despite possible contradictions in his/her own private information signals—engages in the same acts. A cascade develops, then, when people “abandon their own information in favor of inferences based on earlier people’s actions”.[1] Information cascades provide an explanation for how such situations can occur, how likely they are to cascade incorrect information or actions, how such behavior may arise and desist rapidly, and how effective attempts to originate a cascade tend to be under different conditions. By explaining all of these things, the original Independent Cascade model sought to improve on previous models that were unable to explain cascades of irrational behavior, a cascade’s fragility, or the short-lived nature of certain cascades.”
