It is very common for individuals to take IQ tests nowadays as a way to assess their intelligence. However, many people might be doubtful whether IQ tests give an accurate representation of a person's degree of intelligence. In order for us to find out whether standard IQ tests are accurate, we can begin by learning about the backdrop of IQ tests.
Background of IQ Tests
Sir Frances Galton was one of the first scientists to introduce the Intelligence Quotient Test. This British scientist conducted research and made comparisons of various people based on their abilities to complete certain tasks. His study assured him that there should be a method to measure human intelligence. After Galton, a different kind of IQ test was created by Alfred Binet, a French psychologist. Together with Theodore Simon, Binet developed tests for memory, vocabulary, practical experience, reasoning, and problem solving skills. In comparison to Galton's test, the Binet-Simon IQ test was more accurate in predicting academic success, and it is still the standard formula that a lot of today's intelligence tests were derived. Alfred Binet's test was brought to the United States by Henry Goddard. There, the formula was revised by Lewis Terman, along with a new scoring system was created. With this scoring system, a person's IQ test score is going to be judged against the performance of people of the identical age.
Accuracy of normal IQ Tests
Are standard IQ tests really accurate? People often wonder why many people who're bright in class avoid very well in IQ tests. On the other hand, people who don't do well at school may excel in IQ tests. It doesn't mean that IQ tests aren't accurate. It only means that many people are smarter with regards to logic and reasoning, while some have better memory skills. Because school examinations cover such a wide array of topics, it is not easy to evaluate the general intelligence of the person. Students may prosper for one or two subjects that they are exceptionally proficient at, while scoring lower marks for subjects that they're not too interested in. There are people with low IQ test scores which do perfectly for their exams and also the cause of this might be just that they've studied harder than others. It has absolutely nothing to use logic and reasoning skills; it's really a few determination and difficult work. Therefore, the phrase intelligence is really a continuous debate.
IQ Tests for single and multiple abilities
People also wonder whether intelligence is just a measure for a single ability or several different abilities. Are you currently considered generally intelligent if you are only good in Mathematics? Or are you considered intelligent in Mathematics and just average in overall intelligence? It all depends on how the thing is it. Today's IQ tests are accurate as long as you consider the aspects of intelligence they measure. Intelligence continues to be something that can't be defined by a universal value. A genius may show exceptional intelligence in a certain field of study, but he is able to be quite slow-witted in other subjects. Is such an individual considered intelligent?
Multiple IQ exams are generally better, because they assess an individual's intelligence in different fields of mental abilities as well as give a better account of a person's overall intelligence. In multiple IQ tests, a person's scores from various standard IQ tests will be added up and then divided to create a typical. A good thing about taking multiple IQ tests is you reduce the effects of certain variations in environmental factors, for example stress and mood.
How environmental factors can impact the precision of IQ tests?
Research has shown that the standard IQ test is an accurate way of measuring an individual's intelligence, only that there are certain environmental factors that may affect it. It has been established that is a result of the score of the standard IQ test may vary up to 15 points, if the person who is being tested is impacted by factors for example mood, anxiety, emotions and biochemistry. To be able to lessen the effects of these environmental factors, lots of people choose to take multiple IQ tests instead of single standard IQ tests, simply because the previous provides a better representation of intelligence.
