Just relying on 78 responses to claim that 75% of people plan their papers weeks in advance and others do not, ignores the menu of real reasons behind these behaviors.
There is always a third way, a more nuanced explanation than just "stress" or "laziness".
For example, for administrative delays here in Morocco, even the best intentions cannot always avoid unforeseen delays at Mouqataa or with the passport service.
We should rather ask if people have external constraints that are unforeseen, rather than just poor time management.
An advanced planning is a luxury not everyone can afford when trips are decided at the last minute for family or professional reasons.
