 If there is no biological factor that accounts for the statistical discrepancy, then by process of elimination, we must be talking about socio-econometric factors.

I will posit that statistically Germans per capita play the accordion more than other nationalities.  I don't believe that even here anyone would argue that there is a biological factor for that.  So, must it be socioeconomic by the process of elimination?

If one found that Europeans had better foot-eye coordination than people in Kansas, is that a biological or socioeconomic factor of one group or the other?

If Hawaiians eat more seafood than do the people in South Dakota, is that a biological or socioeconomic factor of one or the other?
