Information Cascade - Wikipedia - political polarization  ## Metadata - Author: **political polarization** - Full Title: Information Cascade - Wikipedia - Category: #articles - URL: https://en.wikipedia.org/wiki/Information_cascade ## Highlights - An Information cascade or informational cascade is a phenomenon described in behavioral economics and network theory in which a number of people make the same decision in a sequential fashion. It is similar to, but distinct from herd behavior.[1][2][3] An information cascade is generally accepted as a two-step process. For a cascade to begin an individual must encounter a scenario with a decision, typically a binary one. Second, outside factors can influence this decision (typically, through the observation of actions and their outcomes of other individuals in similar scenarios).
