You mistake repeated headlines for objective reality.
An availability cascade occurs when a chain of expressed perceptions triggers a public belief through repetitive reinforcement.
As a claim is repeated across media, it becomes more accessible in your memory, leading you to assume its truth based on its frequency. The belief gains legitimacy not from data, but from the social visibility of the idea. The world feels like what you hear most often.
Repetition is frequently mistaken for evidence.
