You can't cherry pick your examples, you have to look at the entire aggregate. If that aggregate is trending to shift one way then you either have a basis for a hypothesis or a serious data error. There are Eastern European countries that nod their head up & down to indicate "no". When they nod in America, what does that indicate?

My sosh prof used to say: when you positively know the answer, you don't have enough data
