An intelligence quotient (IQ) is a total score derived from several standardized tests designed to assess human intelligence.
An IQ test consists of a number of tasks measuring various measures of intelligence including short-term memory, analytical thinking, mathematical ability and spatial recognition. Like all IQ tests it does not attempt to measure the amount of information you have learned but rather your capacity to learn.
Intelligence is NOT knowledge! Knowledge is the collection of skills and information a person has acquired through experience or learning whereas intelligence is the ability to apply such knowledge. A person who knows nothing may still be highly intelligent:
The “Flynn effect”
The fact that each generation scores higher on an IQ test than the generation before it is called the “Flynn effect”. It is fully present in pre-school children, does not increase during the school age years and is greater for non-verbal abilities than for verbal abilities.
In this fast-paced spin through the cognitive history of the 20th century, moral philosopher James Flynn challenges our fundamental assumptions about intelligence.
Are we actually getting smarter, or just thinking differently? He suggests that changes in the way we think have had surprising (and not always positive) consequences.
CFIT stands for Culture Fair Intelligence Test. What does ‘culture fair’ mean? This nonverbal intelligence test is culture fair because it avoids cultural and language biases and focuses on logical reasoning only.
The benefits are quite obvious: All may step up at the starting line with the very same equal opportunity, regardless of their cultural (therefore ‘culture fair’) i.e. educational, language and other backgrounds. Even a illiterate person can take such a CFIT and benefits from common prerequisites.
At its extreme, culture does impact IQ scores. That means that what we think of as intelligence here means a lot in some places and rather little in others. According to some researchers, the “cultural specificity” of intelligence makes IQ tests biased towards the environments in which they were developed – namely white, Western society. This makes them potentially problematic in culturally diverse settings.
The test may be based on the highly scientifically validated progressive matrices test of John Raven but was originally constructed by Raymond Cattell as an attempt to measure cognitive abilities devoid of sociocultural and environmental influences.
Cattell proposed that general intelligence comprises both fluid intelligence and crystallized intelligence. Fluid intelligence is the ability to solve novel reasoning problems and is correlated with a number of important skills such as comprehension, problem solving, and learning. Crystallized intelligence, on the other hand, involves the ability to deduce secondary relational abstractions by applying previously learned primary relational abstractions.
I always get very much amused if one talks about IQ tests, results thereof and even dares compare these outcomes with one another. There are countless IQ test varieties out there and so naturally are the results.
That’s why it’s impossible to compare such results unless they are based on the very same IQ test and conditions or at least correctly converted according to IQ classifications (also taking into account stdev – standard deviation), for example:
- Cattell-IQ = (Wechsler-IQ – 100) * 24/15 + 100
- Wechsler-IQ = (Cattell-IQ – 100) * 15/24 + 100
Convergent Validity is the extent to which the CFIT correlates with other tests of intelligence, achievement, and aptitude. The intercorrelations between the Culture Fair Intelligence Test and some other IQ tests have been reported as shown in the table here: Cattell Culture Fair Intelligence Test.

My IQ Test Results
With this CFIT, I scored above average with 104 and that puts me in a group range that represents a third of the population. With this test, only 5% of the people in the world score 124 or higher – the minimun required to become a member of the International High IQ Society (IHIQS).
