"Sub-cultures" is where the variance is at, but I don't really know what that term means. Razib, what do you mean by that term? The first forms of sub-culture that pop to mind are pretty correlated with parents, e.g. geography, language, SES, etc. Has anybody tried to tease apart not-shared environment?

Has anybody tried to tease apart not-shared environment?

My expectation would be that, culture effects (which I also think are probably major effects) should influence the mean and not the unique variance.
