Sociologists who study organizational collapse have a term for the phase just before failure becomes visible: 'normative drift' — but the more precise mechanism was documented by Diane Vaughan in her forensic account of the Challenger disaster. She found that NASA engineers had observed O-ring anomalies on multiple previous launches. Each time, the rocket survived. And each flight that didn't end in disaster quietly reclassified the anomaly as 'acceptable risk' — not because anyone decided to lower the bar, but because survival itself became the evidence that the bar was in the right place. Vaughan called this 'the normalization of deviance': a structural process where organizations — and people — systematically mistake continued functioning for continued safety. The dangerous habits aren't the ones that immediately break things. They're the ones that keep almost working, long enough to become the new baseline. What you're looking for today isn't where things are going wrong. It's where nothing has gone wrong yet — and where that track record has quietly become your reason to stop looking.

In the last 48 hours, what did you let pass without comment — in yourself or around you — because nothing bad happened last time?
