Proclaiming theories as fact is not a very nice way to proceed in an argument.
That said, please consider a counter-theory to your theory: Due to the fact that many people imprisoned for long terms do end up obtaining their GED and one or more vocations, it seems quite probably that american criminal law is a test of education more than one of genetic factors.
Alas, no. Mental tests in childhood and early adolescence predict subsequent educational failure. The effect is independent of race, culture, parental socioeconomic status, etc.
It merely proved a correlation between mental ability and educational success in the current educational system.
It does not show whether the cause of crime is the actual lack of mental ability, or the failure of the education system to properly prepare them for adult life.
In other words: You've not shown that more effort to educate people would result in the same crime levels as with the current effort.
That said, please consider a counter-theory to your theory: Due to the fact that many people imprisoned for long terms do end up obtaining their GED and one or more vocations, it seems quite probably that american criminal law is a test of education more than one of genetic factors.
