Some people can&#x27;t read a map in North view, that&#x27;s where customer interviews get interesting - they even need a 3D view or the speech. Actually in my IT-engineering school a subgroup couldn&#x27;t read the technical blueprints at all (drawings of mechanical parts in left&#x2F;right section), and it was all the students from Morrocco - even if both their parents were French immigrants with servants and wealth. The only possible explanation I&#x27;ve though about is that they may not have been exposed to Lego when young.
