How can anyone truely judge intelligence. It's virtually impossible as there is a vast differential between education levels, skill levels and specialities...
Education varies from country to country, from community to community, it may be of a far higher standard in one area than it's neighbour.
Furthermore the most intelligent person from Community A may be a genius mathematically, with the ability to calculate and equate numbers instantly, yet he may lack in creativity, the understanding of the arts and he may be poorly able to comprehend literature.

The most intelligent person in community may be an academic unrivalled in his/her ability to perceive and understand even the most riddled literal poetry and literature, yet may be considerably behind person A in terms of mathematical ability.
So how can we truely judge?
Even IQ testing is an unfair examination of aptitude. To undertake to this examination one most conform to one specific way of undertaking the exam-one method of thinking. This will actually limit the ability of the person to perform to their highest ability as it will not allow the individual to approach the examination in their own prefered way.

The final point that i feel i must raise is simplistic and only an opinion.
Your mind is what you make of it. It doesn't matter what colour, race, height or creed you are, your mind is your own to expand if you wish or alternatively to close and corrupt as the people who still continue to discriminate against their fellow man have.
