What is IQ?
IQ, short for intelligent quotient, is the most researched attempt to measure human intelligence and the one with the most practical applications to date.
IQ Scores have been linked to educational success, job performance and even personal income. In general, IQ is considered by many to be a reliable indicator of successful educational, professional, economic and social performance.
IQ research has shown that it is a stronger predictor of educational and professional success than any other single score.
What is an IQ test?
The IQ Score comes from standardized tests developed to assess human intelligence. Several IQ tests have been developed by different researchers that aim to measure intelligence by focusing on different related skills and qualities, such as verbal ability, mathematical understanding, visual ability, short-term memory, pattern recognition, analytical thinking and spatial orientation.
The French psychologist Alfred Binet, together with the psychologists Théodore Simon and Victor Henri, was the first to publish an IQ test (Binet-Simon test) in 1905. It was developed to measure a child’s intelligence and compare it to what their intelligence “should be” based on their age.
Since then, a variety of self-taken IQ tests have been developed and constantly updated. Intelligence researchers have found IQ tests to be among the most accurate (technically speaking, the most reliable and valid) of all psychological tests and assessments.
What do IQ tests measure?
IQ tests do not attempt to measure a person’s general level of knowledge, but rather their actual ability to learn. The final IQ Score can be an indicator of how capable an individual is of solving complex problems of a (mostly) analytical nature.
However, it may be said that IQ tests can only measure a certain part of human intelligence, namely that associated with logic and analytical thinking. There are aspects of human intelligence such as creativity or emotional intelligence that cannot be measured by an IQ test.
The BGI™-certified IQ test measures five different aspects of human intelligence: visual perception, abstract thinking, pattern recognition, spatial orientation and analytical thinking.Start the BGI™-certified IQ test now!
How is IQ measured?
The IQ test consists of a series of questions designed to measure different areas of intelligence, such as visual perception, abstract thinking, pattern recognition, analytical thinking and spatial orientation. Once you have answered the IQ test questions, your results are compared with those of people the same age and then a normalized score is given.
“Normalized” means that the average IQ Score is 100. Your score shows where you stand compared to other peers in your age group who have taken the test. How far you fall on either side of the average IQ Score roughly determines how unusual your IQ is.
IQ Scores follow a normal distribution of statistical data. About 95% of people in the world have scores within two standard deviations (SD) of the mean (average IQ Score). If one SD is 15 points, which is the norm in almost all modern tests, then 95% of the population is in the range 70-130, and 98% is below 131. Alternatively, two-thirds of the population have IQ Scores within one SD of the mean, i.e. in the range 85-115.
Can your IQ improve?
Recent research has shown that a person’s IQ Score can change significantly. There is strong evidence that life and learning experiences can have an impact on the brain and IQ.
Many studies suggest that cognitive training can increase intelligence, and it is possible that we are constantly improving the cognitive skills we want to work on. The human brain is equated by many with a muscle that is strengthened through exercise. Recent neuro-research has also confirmed the brain’s plasticity and demonstrated its ability to form new synapses.
