Attention is a bottleneck, and a survey with only 78 responses on Google Forms is not enough to justify conclusions about such nuanced behaviors.
We are severely lacking context on the real constraints that push people to verify their documents in advance, such as the complexity of renewal processes or the often long consular delays.
Without this vital information, we cannot really say that the survey "informs" verification behavior; it remains a superficial observation.
For example, knowing that 75% of Japanese verify their documents well in advance is one thing, but without knowing the costs and procedures of a visa for America, it is very limited information.
