A cognitive bias which leads people to disbelieve or minimize threat warnings.1 Consequently, individuals underestimate the likelihood of a disaster, when it might affect them, and its potential adverse effects. The normalcy bias causes many people to not adequately prepare for natural disasters, market crashes, and calamities. About 70% of people reportedly display normalcy bias during a disaster.2 The normalcy bias can manifest in response to warnings about disasters and actual catastrophes. Such disasters include market crashes, motor vehicle accidents, natural disasters like a tsunami, and war.
