Hmm. I wonder how much of an impact genetic ability really made. From reading the study it seems like Nurture was a much greater factor. Of course there are other confounding variables like do both parents work, or quality of education before university, but I think that anyone can learn. Was there a true impact from Nature/genetics at all?
Having a genetic makeup that makes you more inclined to education does make a child from a disadvantaged background more likely to go to university, but not as likely as a child with a lower genetic propensity from a more advantaged background.
Very interesting study though.
