The fact is that we tend to jump to conclusions based on survey data.
A Google Forms survey with 78 responses is a good starting point, but it feels more like a description than a deep explanation of motivations.
The boss I see, without being able to prove it completely, is that people interpret raw statistics too quickly as reasons, without digging into the why.
For example, to understand why 75% verify their documents in advance, one should inquire about administrative constraints or the fear of local bureaucracy, not just vacation planning.
A more in-depth qualitative survey on the specific reasons for these behaviors would confirm or refute this impression.
