If you are talking about the same 'general' tests that I have seen, I think the idea of a synthesized problem with abstract concepts is already a strong cultural filter. They may seem very general and obvious to you, but someone not used to such a premise might well be completely thrown off, without necessarily being less 'intelligent' as it were (powers of deduction and reasoning, problem solving, etc.).
