Aptitude tests
Apparently aptitude tests do not prove jack all according to my psychologist sister. They are merely a weeding tool used because there is nothing else that can reduce huge number of applicants.
Just because one can see figures and their relationship to each other simply proves that one has this ability. People without simply use another part of the brain to make alternate strategies.
She reckons that our innate hard wired "warrior qualities" that both men and woman are born with demonstrate more readily the qualities needed to fly. It just takes more time to access them and assess them because of the culture, education and life experience we all have gotten from society.
Just a thought.
