Sorry I don't have time to lose! Keep hating on rather than trying to understand and don't forget to downvote and to put a reply nobody will read

Ok, I'll explain my reasoning so you can understand : We observe that if one's father went to a GE, one has a higher chance of getting in the GE. However, we know that the GE's selection system is based upon highly difficult maths exams, and that IQ is in large part inheritable. Thus we can assume that we will see more or less the same trend if we replace "father" by "mother".

You're making weird appeals to motives, probably because you're the one who got his little socialist worldview burst.

I never assumed that, I really just said IQ was heritable

No I meant that IQ is highly heritable, although there is a correlation between wealth and IQ

It's called biology

Intelligence is highly hereditary in developed countries, so I guess it should work aswell
