Why Are Americans So Stupid?

I think when people say that they often mean ignorant or a narrow world view. There are people in all countries who don't have a broad world view or aren't particularly concerned with current events other than things that will affect their daily lives. I think the difference with America is that it's so exposed to the rest of the world, mainly through media, so we get to see people from all different backgrounds and places. Americans are generally seen as quite bold and outspoken. So it's probably a combo of those things. I've met a lot of smart knowledgeable Americans and I do get what you mean, just giving my view as someone from overseas.
