Ah, survivor bias. Reminds me of analysis of damage to bombers in WW2. Data showed most damage was done to the wings and body of planes. The tail, cockpit and engines were rarely damaged. They responded by reinforcing those areas that were frequently damaged.

However they were only observing bombers that made it back to base and so data on planes that were shot down was missing. Luckily someone did eventually realise this and so the research could be used as evidence that strikes to the areas rarely recorded indicated a downed plane.

The full office being pulled into a meeting and lectured about how disheartening it was to see everyone leaving the office on time at the end of working hours. What we call good time management they apparently saw an laziness and a lack of commitment.

That and the message that discussing pay and bonuses wasn’t allowed (despite being protected by the Equalities Act here in the UK). This of course got us wondering why this would be discouraged and turns out our salaries seemed to have very little to do with length of service or performance.
