"Koro is a culture-bound syndrome delusional disorder in which an individual has an overpowering belief that his or her sex organs are retracting and will disappear"
> In a typical case of running amok, an individual (often male), having shown no previous sign of anger or any inclination to violence, will acquire a weapon (traditionally a sword or dagger, but currently any of a variety of weapons) and in a sudden frenzy, will attempt to kill or seriously injure anyone he encounters and himself.

Culture-bound syndromes are fascinating.
Implying Americans are crazier seems odd. What would cause that? Higher rates of mental illness making their ancestors emigrate from their original countries? Is there any data on that? Western Diet causing mental illness? Too much empty space?
I'm not implying that (also, no need to imply such a thing, de facto knowledge at this point). I'm implying that the culture in US has a lot more UFOs in it, every major blockbuster alien movie has been produced in the US, as far as I know. Most if not all UFO sightings that gets reported around the world comes from the US. Flying experiments could contribute to that as well, which also go into the culture in the US of doing experimental aircrafts in order to achieve flight-superiority.
This seems like a sort of sampling bias as a consequence of America being really good at exporting its culture.
