@genoves,
It is not just how high your IQ is but how you use your intellegens.
Lately also EQ (emotional ) is tested. If Obamas IQ is 121 and his EQ is high he will make a good leader - president or not.
How is a person´s logical thinking - can that person draw conclusions of things experienced or not.? There are people who knows all kinds of facts, but cannot draw a conclusion of two facts put together.
A person can have a high IQ and learn a lot, but have difficulties by oral tests or by expressing themselves amongst other people - with other words being shy.
That person will never be a good leader, but be good in working by him/herself.
Others with a lower IQ might be able to talk a lot and express themselves with all kinds of fancy words learned by heart. They impress people, but might not be such good leaders nor good at work.
Don´t judge people from their IQ - judge people how they are.
