Singaporeans are already have difficulties getting along well
with one another on a genuine daily basis.
Cultural Intelligence? Let me lie and tell you YES ok? 
Depends on which kind of Cultural Intelligence you are after. If
it's those put on a false mask and become everyone's best friend
type of cultural intelligence, then of course I will tell you that
Singaporeans excel very well in it.
But if you're after the genuine kind, then I can tell you maybe
not many Singaporeans can actually excel in it.
