So, I know how to deal with shit tests, for the most part (DARE, never DEER), but how do you know if it's a shit test or not?

One that I'm thinking of is the "don't have sex before marriage" shit test. In the US, that's a joke. When I'm on vacation in the Middle East, how do I know the difference?

My gut tells me to game anyway. But is there a way to verify?
