It smells like a hasty correlation here between the simple fact that a survey was conducted and the interpretation of its results.
My intuition tells me that just because a survey has been filled out, it doesn't make it a reliable source for understanding a behavior like verifying identity documents.
The sampling bias or the phrasing of questions can easily distort conclusions.
There is a lack of transparency on the methodology to validate such a link.
If the 78 responses come solely from a group of highly organized travelers, it biases our perception of the majority.
