Let's get rid of the media hype: a survey on vacation planning habits, even online, does not make these figures universally valid for document verification.
These 78 responses via Google Forms are a specific observation, not an unbreakable law to say that 75% of travelers plan ahead.
What concretely changes?
Here in Germany, bureaucracy is such that checking your papers months in advance is a practical necessity to avoid complications, not just a preference.
If the survey did not question a representative group of international travelers with various administrative constraints, then its conclusions do not apply to everyone.
