I just saw this http://www.upworthy.com/things-america-is-less-gooder-at-basic-scientific-comprehension?c=la1&g=2 image showing GDP vs. belief in evoluation.  The authors proclaimed that this was due to lack of scientific education (which, I do think the US is lacking); however, I think there could be other explanations.  For example, science education might be okay, but it’s not enough to overtop trandition and customs.

Anyway, just an interesing comparison.
