Problems with IQ Tests in Psychology
If you are already familiar with the IQ test and what exactly it does, you’ll find it easy to understand the essence of this article – Problems with IQ tests in Psychology. So let’s quickly examine the IQ test briefly.
The IQ test is a psychometrically developed instrument for the purpose of measuring intelligence – a type of cognitive ability. There are other types of cognitive abilities that can be tested but not so much with the IQ test. For instance, memory, creativity, and visuo-spatial abilities are some types of cognitive ability tests.
No matter how psychometrically appropriate an IQ test is designed to measure what it ought to measure (validity) and be able to deliver consistent results (reliability), it cannot be devoid of some ugly flaws. In order not to deviate too much from the essence of this article, let’s quickly have a look at some problem with the IQ test.
Intelligence Quotient or IQ is a numerical measure of your intelligence. Some schools use the IQ test as a way to gauge how college students are doing and observe for a financial useful resource. the problem is that IQ testing doesn't paint the full photograph of someone's intelligence; the Wechsler test and the Stanford-Binet intelligence scales, which are both normally used to determine one's IQ on a scale of around 70 to 165, says the US.
Now, let's have a look at some problems with the IQ test as a measure of the behavioural attribute called intelligence.
1. Limited capability and stereotypes
IQ tests can restrict intelligence and perpetuate stereotypes within a classroom environment. For instance, minorities and economically-challenged generally rating worse than the advantaged people, Also, upon receiving the end result of a bad IQ result, a look at the person may additionally consider that they are "silly" or much less clever than their peers while it isn't their fault. In addition, better-off college students with higher ratings may be treated favorably than their IQ-disadvantaged counterpart.
2. A biased determinant of the norm
The size of an IQ test is decided upon by using scoring, norm, and selection criteria are drawn from a given population. Alas, that representation to serve as a determinant to a larger group can't in all likelihood measure everybody's IQ generally. More samples from every culture, age, sex etc should be the focus of unbiased IQ test - this can, however, be a herculean task on the part of test developers and psychometrist.
3. Myopic topics
A traditional IQ test examines people in subjects like analyzing comprehension, limits, collection and mathematical expertise, but they don't take a look at for subjects that consist of mechanics, social competencies or creativity. Pretty virtually, IQ tests are an ineffective manner to measure intelligence, as intelligence itself is made up of various aspects, subjects, and competencies.
4. Predictive abilities
someone who gains an excessive rating on IQ testing may not mechanically enjoy a high level of success in her life. IQ tests are negative predictors of socioeconomic and fulfillment. This can render them pretty vain for predicting later fulfillment in life.
Now what?
'Is the IQ test totally unuseful?' should be resounding in your head right now but the simple answer to this question is an absolute 'NO'. Thanks to the Psychology of cognition and a whole lot of new developments in Psychological science which have made at least, an effort to kick-start an entity that could help our judgment on intelligence - another behavioral attribute seeming uneasy to fathom as there are still much to unravel.
