The following are some facts about the IQ test that you should understand.
What Is an IQ Test?
IQ test or Intelligence Quotient is an assessment that is intended to measure various kinds of cognitive abilities of a person. The test results will be displayed in the form of a score as a measure of a person’s ability and intellectual potential. Until now, the IQ test is still one of the psychological tests that is often carried out. The IQ test was first created by a French psychologist named Alfred Binet in the early 20th century. The form of the test itself, namely the Stanford-Binet, is still used today.
Then, this one test began to be developed again by a psychologist named Charles Spearman with the concept of overall intelligence or mental ability to perform various kinds of cognitive tasks. Some of the aspects that are considered include language skills, mathematics, speed in processing or learning, memory storage, visual processing, and also reasoning abilities.
The following are the levels of IQ scores:
– 69 and below: Intellectual Disability (very low)
– 70-79: Borderline (limit intellectual function)
– 80-89: Low Average
– 90-109: Average
– 110-119: High Average
– 120-129: Superior (above average)
– 130 and above: Very Superior (intelligent)
Higher IQ scores are often associated with higher academic ability. People who have a high IQ are judged to be easier to achieve higher achievements in school. Meanwhile, people who have low IQ scores are often associated with intellectual disorders.
Facts to Understand Before Taking an IQ Test
Before deciding to take an IQ test, there are several important things that you must understand about this cognitive intelligence test, including:
1. IQ Tests Are Not the Only Determinants of Someone’s Intelligence
This IQ test can indeed provide an overview regarding a person’s ability to learn something or at work. However, you don’t need to rely solely on an IQ test. Because this test will only show intelligence from a cognitive perspective. Meanwhile, intelligence itself is not limited to just a matter of logic. But also creativity, empathy, spiritual, social, and so forth. It cannot be measured on an IQ test.
Not only that, a study proves that the background of the test taker can also affect the results of a person’s IQ test. Where people who often play computer games will tend to get higher scores on reasoning tests and also short term memory. Whereas test takers who have anxiety problems will get lower short-term memory test results. Then, the complexity of the human brain today has begun to evolve. IQ test questions that were created in ancient times may no longer be relevant.
2. IQ Score Cannot Reflect Who You Are
People who have high IQs such as Albert Einstein, Stephen Hawking, and also Terence Tao, where they are successful and well known to the world. However, a high IQ score cannot guarantee that someone will be happier, smarter, sane, and also prosperous. Vice versa, a low IQ score does not always mean that the person has intellectual retardation, is mentally disturbed, and also cannot be a financially successful person. There is also someone who theoretically belongs to intelligent people but has mediocre achievements.
Even though he has a score of 50 on the IQ test and is declared a stupid person or even has academic special needs. But in reality, the ability to drive can still be obtained by people who have an IQ score between 50 to 75. On average, people who have a low IQ are proven to be successful in their field of work. In addition, they can also have offspring with an average or even higher IQ and can live successfully.
3. The Higher the IQ, The Higher the Risk of Mental Disorders
Have you ever watched a movie called A Beautiful Mind starring Russell Crowe? The film is a biography that tells about the life of John Nash, a famous mathematician and also a Nobel laureate in economics, but he has schizophrenia.
In addition, David Foster Wallace, a world-famous writer, also struggled with depression for more than 20 years before he finally decided to commit suicide in 2008. So, the link between IQ test scores and the risk of mental illness has also earned names. names like Abraham Lincoln, Isaac Newton, and Ernest Hemingway. No one knows for sure what causes an increased risk of mental disorders in someone with a high IQ. However, a study found that this possibility is influenced by the NCS-1 gene which is responsible for maintaining the activity and also the strength of the connections between nerves in the brain.
People who are classified as intelligent have a higher number of NCS-1 receptors compared to other ordinary people. This increase in the number of NCS-1 receptors has been linked to the risk of schizophrenia as well as bipolar disorder. Not only that, other studies have also found that people who show the best intelligence performance on math tests, they will tend to have bipolar disorder.
4. IQ Test Scores Can Go Up and Down
The next fact about the IQ test is that the score on this intelligence test will not always be the same from time to time. IQ test results are very subject to change since the first time you took the test as a child. Because, a person’s intelligence is not only influenced by academic history, but also from life experiences and also how they socialize in society.
The rise and fall of this IQ score is also associated with changes in the brain with age. The brains of young children are not fully developed. So, maybe the IQ test results will be lower when compared to when they started growing. Then, the theory according to Richard Nisbett, a psychology lecturer from the University of Michigan, can change at any time. In modern society, the ability of the brain will also increase. So it is very likely that the IQ score will increase by 3 points every 10 years.
However, whatever the results, this cognitive intelligence test is not a determinant that can predict our future. Actually, it is human character that is more complex than just the level of intelligence. So, don’t let your IQ test score keep you from continuing to strive for success.
