Not to sound degrading but I don't believe in this IQ testing business... I had an IQ test done in my early teens and got 128 which supposedly is above average in the higher end but still the way the tests are designed does not take into account many factors. The questions being posed, etc... culture, society, upbringing, etc... as well as application of what's on the test. What if at one point in life you're good at that, and later in life you forget these things? I was pretty damn good at math at one point then I just stopped doing math (seriously). Or vice versa? What about the presentation of the questions taking into account the understanding of other cultures and societies? The same cannot be asked or assumed of all people.
Our God given intellect is unique and everyone has certain abilities, scopes, etc... it could be anyone, however intellect can be of a variety of applications and scopes... someone who never went to school could have intellect that does not get recognized and yet?... Someone who doesn't do well in an IQ test could be intelligent, wise, etc... and yet?
Likewise I don't believe in formal education as something that guarantees intellect either, some people believe if they get so and so degrees and they plaster these papers in their house, office, etc... it does not necessarily mean they are adept at what they could do.
And finally someone could be intelligent or wise enough to invent things, lead people, etc... and never have done an iq test or done poorly on one and they may be more valuable to mankind than someone who just scores high on an iq test?
