Why Normalcy Bias Can Wreck Your Decisions
The most expensive sentence in any planning meeting is four words long: “that’s never happened before.” Normalcy bias is the mind’s quiet refusal to prepare for an event it hasn’t personally lived through. Most weeks resemble most other weeks, so the brain runs that calm straight out across the planning horizon — and treats the genuinely unprecedented as not-quite-real until it is already happening.
Usually that’s the smart move. If you treated every new warning as the start of a catastrophe, you’d never get out of bed in the morning; efficiency is the entire point of the shortcut. But every so often the world hands you something with no precedent in your own experience, and the same reflex that keeps you sane on an ordinary Tuesday is the one that files the once-in-a-generation event under “someone else’s problem.”
The discipline is telling the two apart on purpose: asking, deliberately, what you are currently treating as too far-fetched to plan for — and building the plan anyway. That habit is the difference between an analyst and a spectator. So what are you filing under “that won’t happen here” right now?
