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! A person who knows nothing may still be highly intelligent:
The “Flynn effect”
Why our IQ levels are higher than our grandparents’
The fact that each generation scores higher on an IQ test than the generation before it is called the “Flynn effect”. 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 test may be based on the highly scientifically validated progressive matrices test of John Raven but was originally constructed by Raymond Cattell.
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.
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 (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 intelligence tests have been reported, as shown in the Table below.
Correlations of the CFIT with other IQ tests
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 European IQ Test (the English version), I scored 25 correct (out of a possible 33). This implies an IQ of about 150 on the Cattell scale (stdev 24), about 133 on the Stanford-Binet scale (stdev 16) or about 131 on the Wechsler scale (stdev 15).
According to IQ classifications, my IQ test results put me in a range somewhere between…
…(according to Cattell) highly intelligent, (according to Wechsler) very superior / upper extreme and (according to Stanford-Binet) gifted or very advanced.
