Let's dispel the media hype: 78 responses on a Google Form won't concretely change travel habits of anyone. It's a tiny, self-selected sample, not a solid basis for general conclusions. Claiming that 75% of travelers check their documents in advance based on so little data is a bit light.
To prove such behavior on a large scale, hundreds or thousands of participants and a more robust methodology would be needed; otherwise, it's like basing national statistics on my circle of friends who always eat Currywurst. This type of survey only gives us an indication, not a proven truth about what works or not for the population.
