Feeling like… a somewhat too quick interpretation of what the data really tell us about identity document verification habits.
Although the general survey on vacation planning can offer context, it doesn't directly provide proof or the explanatory mechanism for the specific behavior.
In Spain, for example, the delay to get an appointment (“cita previa”) to renew a DNI or passport can be long, which forces people to plan very far in advance, regardless of their planning nature.
It's less a planning habit than an administrative constraint that drives anticipation.
To truly confirm this, specific questions in the survey about motivations behind document verification, such as expiration or visa requirements, would be needed.
