They could probably get similar results in every country, one of the places I used to work I decided to ask everyone I spoke to that day how many sides a cube had... Many got it wrong...
This is what i wonderd, Although some questions are even easyer then the sides on a cube

So i thought id ask someone living there.
I know we can get some dumb ****s down here aswell though, All you need to do is go near a group of teenie boppers or a bogan fest
