Normalcy Bias
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Refers to the tendency of people, when facing an impending disaster, to assume that "everything is as normal," underestimating the likelihood and severity of the danger, leading to delayed evacuation or inadequate preparation (e.g., passengers on the Titanic reluctant to board lifeboats).
SCAFFOLDING EFFECT
Reduce cognitive load
Overcome serious wishful thinking. In the early stages of a black swan event, the brain deceives us into thinking "it's not that abnormal." One must rationally counteract this instinct, follow the principle of "better safe than sorry," and take action.
Anchor fast decisions
When facing abnormal threats, the brain's prior inertia of "everything is normal" underestimates risk, leading to delayed preparation and action.
