The idea that a simple Google Forms survey explains why people verify their documents well in advance is an excessive simplification.
Here in Italy, we don’t check papers weeks in advance out of simple planning habit, but due to administrative survival.
Who among these 75% has already missed a flight because of a missing marca da bollo or expired document? It’s the fear of disaster that motivates, not just the desire to do well.
Survey data doesn’t capture the bureaucratic pressure experienced, which forces anticipation to avoid catastrophic delays like at the Questura.
The real reason is often bitter experience and the desire to avoid concrete complications, much more than simple planning preferences.
