Let's forget what we've invested: simply conducting a survey on vacation planning habits does not justify drawing direct conclusions about identity document verification without a clear mechanism explaining how one informs the other.
The link between a general vacation survey and the specific behavior of verifying identity documents is often tenuous, inviting us to walk away from hasty conclusions.
For example, if the vacation survey did not include any questions about passports or visas, it's difficult to have that data to explain why some verify their documents early or late.
