Why does IQ fail at determining exact intelligence?

Some people feel that they are already very intelligent once they get a high score in their IQ test. Over the past years, it has been proven that intelligence cannot be measured by the score that will be received.

There are some people who are speculating that the IQ test may become obsolete in the future especially if more and more studies will continue to discredit the various IQ tests available. If you get a low score in the IQ test, do not be discouraged. There are various factors that may affect the type of score that you will get. It is not solely dependent on your level of intelligence.

I think it is more a failure of people to realize that there is no such thing as "exact intelligence" The IQ - intelligence quotient - is a measure derived from a number of different intellectual areas: memory, vocabulary, verbal reasoning, spatial skill, non-verbal reasoning. If a reliable and valid test is used, such as the Wechsler Scales, the resulting IQ should be a good measure of present intellectual functioning.

If you seek something akin to the number of seconds a runner takes to cover a set distance, you will be disappointed. There is no discrete point at which someone's intellectual ability falls. A seasoned psychologist will normally give IQ test results as a range within which the individual's score will fall 90% of the time.
