If you ask do you reside on land to the left side of the atlantic, it is yes/no. Where the one answer implies the other. It is trivial to convert these types of two examples to yes no questions. I was just pointing out that no would mean you include the rest of the world. It would be better to start zoning him off. That is follow up with northern or southern hemisphere. Use large land areas such as Europe, Asia and start pinning his location down. Then ask general job related questions. Is your main profession highly numeric, which includes accountants, mathematicians, programmers etc
It would be better to ask a broader question e.g. Left side of atlantic or right.
Left/Right is not a valid question cause it is not a Yes/No question.
that's why I asked for the timezone :) (UTC+1 or less)
if yes, this would restrict this to everything west of europe (+ GB and parts of africa)
