Have they tested other nationalities too or is it just another "let's laugh at the silly yanks" thing?
Not intended as that at all. American group, linked to the Smithsonian, publishing results on the Americans they tested.
Though they did ask some other questions with some revealing results. Apparently 44% of those surveyed think America ranks at the bottom when compared to other "developed" nations, and 46% think science is "too hard".
Just wondering if other nationalities have been tested. There was no box to tick in the demographic questions at the end.
The results from the online test are not counted (because it is too easy to cheat) - they only published the results from a proper survey.
