Education? Or more directly, socio-economics.

The many of the subjects tested never had any experience with this kind of formal testing, had little to no education, and of course predictably failed on several abstract tasks. It might be that the very pattern of sitting down and intensely focusing on apparently meaningless problems isn't as innate as expected.

Eh, I wish we could retire socioeconomics as a valid term. It can mean just about any factor and for it to be used it scientific publications and even normal discourse that goes beyond Facebook level discussion, feel a little counter-productive.

What, exactly, did you mean though?

		I thought I was being clear. Access to education, which is a function of wealth, race segregation, and/or cultural expectations, or in other words, economic + social factors. For example, if a family encourages their child to work from the earliest allowed age at the expense of schooling, that's a manifestation of both economic and social pressures.
