The essence of IQ
Intelligence quotient or IQ instead of being a special type of test, is a method to score various standardized tests
The tests attempt to measure intelligence, which can be defined as a capability to reason, think abstractly, learn and solve problems
IQ=Mental age/Chronological age*100 :
IQ tests are designed to measure above mentioned mental age or intelligence, which is then divided by the chronological age or real age of a person, and expressed in percentage terms
E xample : if a 20 years old person scores 20 in a test that measures mental age, he has IQ score of 100, which is the population average

Why different IQs are incomparable? (I)
Even though the standardized IQ test s attempt to include diverse fields to measure one’s intelligence, they are becoming more and more focused :
If a person scores high in IQ tests that is more focused on verbal capabilities, it doesn’t mean that he will also score high in a test that measures mathematical abilities
Modern IQ scores are calculated according to a different scale than the ones from the middle of 20th century
both methods yield similar results for medium IQ scores, for high IQs the old method gives substantially higher results

Is Shakira more intelligent than George Bush ?
In order to prove that Shakira is more inteligent than George Bush or Ronald Reagan one should have the following evidence :
Shakira should have been taken the same IQ tests that the presidents took
Their scores should be calculated using the same scales and standard deviations.
All of them should be at similar age at the time when taking the test
if Shakira was prepared for the IQ test through purposeful trainings - it could partly explain the fact of higher IQ score
As there is actually no information about criteria of measuring IQs for different famous people – comparisons of IQs are not objective and may give false perceptions
One question still remains unanswered – how was the IQ of Michelangelo measured!?!
