>>509178637 (OP)all current classification and categorization was made and it's propagate by dimwits.
Look at your gay map for example, everthing between 0.6 and 0.9 are being hold back one way or another, fore (((reasons))), everything between 0.6 and bellow are being prop-up.
Also just taking this index as relevant or valid since education is relative, and not as international as people think, there's some country curriculum that are down right retarded, even in countries with higher HDI, like burger-land, HDI high? Still living like peasants and measure things with inches and dicks.
Even some academic graduates, mostly because their specialty has fuck all to do with math and physical constant.
And even then, a diploma doesn't make you immune of acting like a retarded, matter of fact it has nothing to do with it. A sophisticate and snob retard, is still a retard.
