I don;'t even know if i can follow the point of this conversation. Are we measuring intellegence with one another or generally?
The thing about educaitons is it has been set up to a one size fits all- which we know it doesn't.
Every individual has a different learning curve and even then they have various degrees of levels of attainment.
As an example my friend went to Private school and was never diagniosed as having dyslexia- failed all academic exams, however, she is a very successful business woman- multi millionaire.
My nephew has Autism he is an absolute genius with numbers, cannot communcate at an intellectual level. he is also more IT savvy than his teacher- he is 9.
Some people can read an instruction manual and withou tchecking it again can build something
Some people can build something by watching some one else and copying them.
It depends on your learning curve. Exams do not measure how employable someone is.
Being a snob about money or education is a sad pastime for many.
