It's very common for people to consider IQ tests nowadays as a way to assess their intelligence. However, many people may be doubtful whether IQ tests give a precise representation of the person's level of intelligence. To ensure that us to find out whether standard IQ tests are accurate, we are able to begin by learning about the backdrop of IQ tests.
Background of IQ Tests
Sir Frances Galton was among the first scientists to introduce the Intelligence Quotient Test. This British scientist conducted research making comparisons of various people based on their abilities to complete certain tasks. His study assured him there should be a method to measure human intelligence. After Galton, a different type of IQ test was developed by Alfred Binet, a French psychologist. Together with Theodore Simon, Binet developed tests for memory, vocabulary, practical knowledge, reasoning, and problem solving skills. Compared to Galton's test, the Binet-Simon IQ test was better in predicting academic success, and it is still the standard formula that many of today's intelligence tests were derived. Alfred Binet's test was delivered to the United States by Henry Goddard. There, the formula was revised by Lewis Terman, and a new scoring system was developed. With this scoring system, an individual's IQ test score is going to be judged against the performance of individuals of the identical age.
Accuracy of standard IQ Tests
Are standard IQ tests really accurate? People often wonder why many people who are bright at school don't do very well in IQ tests. However, people who avoid well in class may succeed in IQ tests. It doesn't imply that IQ tests aren't accurate. It just means that many people are smarter when it comes to logic and reasoning, while others have better memory skills. Because school examinations cover this type of range of topics, it is not easy to evaluate the overall intelligence of a person. Students may do well for just one or two subjects that they're exceptionally good at, while scoring lower marks for subjects that they are not so thinking about. There are people with low IQ test scores which do very well for their exams and also the reason behind this might be just that they've studied harder than the others. It has nothing to use logic and reasoning skills; it is just a few determination and hard work. Therefore, the phrase intelligence is really a continuous debate.
IQ Tests for single and multiple abilities
People also wonder if intelligence is just a measure for any single ability or a number of different abilities. Are you considered generally intelligent if you are only good in Mathematics? Or are you considered intelligent in Mathematics and merely average in overall intelligence? It all depends on how the thing is it. Today's IQ exams are accurate as long as you consider the facets of intelligence they measure. Intelligence is still something that cannot be defined by a universal value. A genius may show exceptional intelligence inside a certain field of study, but he is able to be rather slow-witted in other subjects. Is really an individual considered intelligent?
Multiple IQ exams are generally better, simply because they assess a person's intelligence in different fields of mental abilities as well as give a better account of the person's overall intelligence. In multiple IQ tests, a person's scores from various standard IQ tests is going to be added up and then divided to produce an average. One good thing about taking multiple IQ tests is that you reduce the effects of certain variations in environmental factors, such as stress and mood.
How environmental factors can affect the precision of IQ tests?
Research has shown that the standard IQ test is definitely an accurate measure of an individual's intelligence, that there are certain environmental factors that can affect it. It has been established that is a result of the score of the standard IQ test may vary as much as 15 points, if the person who is being tested is impacted by factors such as mood, anxiety, emotions and biochemistry. In order to decrease the effects of these environmental factors, many people choose to take multiple IQ tests instead of single standard IQ tests, simply because the previous provides a better representation of intelligence.
