No offense when I say this, but you seem to be endorsing the idea that intelligence can be raised by education. But the classic idea of intelligence is that one is born with all the intelligence one will ever have. When one's IQ seems to rise after education, it is due to the innate bias of those that make IQ tests. They tend to ask questions that educated people will have the answer for, therefore education appears to increase IQ.
But my understanding of the IQ is that a perfect IQ tests should be about logic and problem solving across many levels. However, because a Scientist can't make a perfect IQ test, bias will creep in showing that education somehow makes you smarter.
To illustrate, take a genius level person that has lived in the jungles of South America all his life. He cannot read, cannot write, cannot do math beyond simple addition. Yet he is an absolute master at thriving in the jungle where you and I would die. Now give him a standard IQ test. He will come out with the ability of a sub moron.
This is because he has no need for reading, writing or math. He's never seen a No. 2 pencil and has no idea what a scan-tron, "fill in the bubble" test is. We simply cannot judge his intelligence, because our tests assume one knows how to read, write and do math.
Now take five years and educate him and then you would start to see his intelligence appear on a genius level. The "logical" thing to assume is that education made him smarter and raised his IQ. That is of course, not true. He was always a genius, we simply could not relate to his genius.
In short, it is the fact that IQ tests have been written by people that went to colleges. Therefore, their bias will creep in no matter what they do. We are all somewhat held and influenced to a degree by our past. That's not a bad thing, bias is not an evil. It simply is.
The incorrect attitude towards bias and I would think the evil thing about bias, is your main point however. Going to school, getting good grades and being told what smart little girls and boys we are is corruptive. If we are so smart, with our college educated selves, than why is the world such a screwed up place? Nearly 99% of politicians, police, teachers, nearly every authority figure today has been to college- and yet we are arguably in a worse position today than ever.
