If this fails, what protects us? The fact that a survey of 78 people shows a trend for document verification does not tell us whether this trend is solid proof or just a coincidence, especially when deep motivations are unclear.
Before drawing hasty conclusions, we must consider the risk of a simplistic interpretation.
A survey on vacation habits cannot be the sole basis for understanding such a critical behavior as identity document verification, especially since legal conditions vary.
For example, in Germany, document verification is a legal necessity, not just a habit, and the absence of this nuance is a flaw in the validity of the explanation.
