There might be some people who
claim to have a very good IQ because they have scored good in
some tests. Some go to the extent of displaying their IQ score
wherein sometimes the score is said to be as high as 120! The
intelligence is directly proportional to the score so is
the prevalent belief. But such a claim and belief is false and
biased. Each IQ test is unique, hence a high score in one test
may cannot be compared to an average score of another test.

A good IQ score is highly subjective. Raw score is what you
obtain when counting the answers that are correct. They should
be evaluated and interpreted using some rules, otherwise it
would be useless. Psychometric principles may be used to
compare two scores, but some issues discussed below cannot be
ignored before coming to a conclusion about the IQ score.
The Title of the IQ Test
It is rather unfortunate that psychologists haven't till now
frozen on a system to compare two IQ scores from two varying
tests. Comparing two scores just on the basis of their
magnitude may not be a very good idea. To determine if a score
is good you have to know what the test is about and what was
the highest score that one secured.
How tough is the test
The second parameter to be focused on is how tough the IQ test
it. It will be easy to know if the score is really good, if we
know how tough is the test. Usually the tougher the test is
the lower one scores. It is highly probable that the IQ scores
of two tests with the same name differ. This is because the
level of difficulty of both the tests is not the same. Those
who design the test decide upon the level of difficulty
depending upon the age group, education and other parameters.
The Matter matters
There can be a lot of tests which have the same title or name
but have different matter or subject they focus on. A 120 IQ
score on one test, say verbal capability doesn't mean you
have the same level on a test with the same name but focus on
mathematical abilities. Usually IQ tests try to include
subject from all other categories, but today IQ tests are
becoming more and more focused. Hence the subject of focus of
the test should also be given its due consideration.
Age: another parameter to be addressed
When you are young, you tend to be a high IQ scorer. As you
grow up the intelligence start deteriorating. But the actual
intelligence that you possess may be different. The label of
test, the level of difficulty or the focus area of the test is
crucial. The highest score that you have got in any IQ test
may not be the correct indicator of your intelligence.
Standard Deviation Units may differ
Mental age was believed to be good enough to evaluate your
intelligence. But soon it was found to be of no use and a
concept of intelligence quotient (IQ) was born. It is ratio of
mental age to chronological age interpreted in percentage. 100
is believed to be an average score and any difference is
believed to be above of below average. This system was good
until it was proved worthless, because the standard deviation
is not the same throughout your life.
All IQ tests don't use same standard deviation. One may use
a standard deviation of 15 and another 20. it is obvious then
that two different scores cannot be compared at the same
level. Hence interpreting a good IQ score becomes all the more
The foundation has vanished
You can find all the above discussed parameters - the level of
difficulty, the matter, standard deviation explained in detail
in the IQ tests. But you will never be able to find the
systedm from which the test was designed.
The system is a perfect sample taken from the population. But
the population cannot be perfect since the pubic varies a lot.
The situation even more convoluted when you compare different
societies. Hence no IQ score can be perfect or be considered
the best, even though the variables remain stable.
IQ Score: does it exist?
No digit cannot be established as a good IQ score. Any such
claim is false and biased. So there neither exists a good IQ
score or a bad one for that matter. But the industry is not at
all concerned to remove this misconception. No efforts are
being taken to clarify this issue by anyone.
