What are the limitations of intelligence quotient?
IQ is SUPPOSED to be (mental age)/(chronological age) *100,
meaning that if you have the intellect of a 20 year old and you're
only 10, you have an IQ of 200. That's the intent, but what does
"mental age" mean. The reality is, an IQ is just a test. People who
do well on tests seem to do better at taking an IQ test. How do you
objectively measure a persons ability? If a person has an ability
that is significantly above average and is able to answer all
questions regarding that subject correctly, the test is
invalidated. In other words, IQ tests are just attempts of
psychologists to measure ability, and they do so using what they
perceive to be the best questions. But in the end, it's just their
perceptions that determine the "best" questions.
