Let us Take a Closer Look at IQ Testing and Why It Is Important

_IQ tests, also sometimes referred to as Intellectual Quotient tests, come in many different shapes and forms. They can be used to help doctors diagnose whether somebody has intellectual disabilities or to see whether someone has superhuman intellect. Below we will take a close look at this form of testing. _

A Brief History of IQ Tests

The very first IQ test was created by Alfred Binet, a French Psychologist at the beginning of the 20th century. However, the IQ testing that we have become more familiar with today came about thanks to the work of Henry Herbert Goddard. He was an American psychologist who studied Psychology at Clark University. He would go on to translate the test that Binet created from French into English. The test was then used to test the basic intellect of American school children and **as a means to support any diagnosis of mental delay. **

To this day, Goddard remains a psychological controversial figure as he believed that adults with a low IQ should not be allowed to have children. There are now a number of different IQ tests that have been created for different purposes, **but the majority of them are used to diagnose learning problems. **


Different Types of IQ Tests

Since Goddard’s modernized version of the Binet Tests, different psychologists have created a number of different IQ tests. Many are intended for use on school children, **but some can actually be used on adults as well. **

Below you can see some of the most common IQ tests:

• Universal Non-verbal Intelligence

• Stanford-Binet Intelligence Scale

• Peabody Individual Achievement Test

• Wechsler Adult Intelligence Scale

• Wechsler Individual Achievement Test

• Differential Ability Scales

• Woodcock Johnson III Tests of Cognitive Disabilities

IQ Test Results

The National institute of Child Health and Human Development states that 85% of intellectually disabled kids get an IQ score of 55-70. **An average IQ score is 100. **

High Scores

In order to be classified as someone with high intelligence, you need to have an IQ score that is above 100. In order to be placed in the extreme intelligence range, you need a score that is higher than 130. Stephen Hawking and Albert Einstein had IQs of 160, which truly puts them in a category of their own. In fact, it is not too farfetched to say that **these two amazing people had superhuman intelligence. **

Low Scores

If you score less than 100 in an IQ test, then you are considered to be a person with below average intelligence. If a person has an IQ that is lower than 70, there is usually a bit of cause for concern as this might suggest an underlying disability.

If a child has a low IQ score, then the doctor might suggest that they do some blood tests, an adaptive skills screening, a brain ultrasound, or a full mental health screening.

Pre-natal screenings can be used to detect intellectual deformity before a child is born. This is a good procedure to carry out in mothers who are older than 35, or those mothers who have taken excessive alcohol or drugs while pregnant. If the test finds any potential issues, **then the doctor will suggest another IQ test when the child is still young. **

IQ Tests to Determine Who Gets the Death Penalty


In 2002, the Supreme Court ruled that anyone who is “mentally retarded” – a term that we no longer use – could not be eligible for the death penalty. This is because it is argued that someone with an extremely low IQ is not intelligent enough to know the true consequences of their actions. If a person has an IQ below 70 and they go on to commit a heinous crime, it is very likely that they will end up with a sentence of life imprisonment and not the death penalty.

How Do You Get an IQ Test?

Proper IQ tests remain unavailable to most of the public. Doctors usually have access to them, but there are many families out there who do not have access to a psychologist or a doctor that can administer a test. This could lead to a lack of crucial testing, **especially during the early years when treatment is more important. **

There are plenty of IQ tests available on the Internet, but these really cannot be relied on for a medical diagnosis. If you believe that a loved one has an intellectual disability, do not sit around and wait for a doctor to offer to test them (you could be waiting a while if you do this), do some research about what your options are and take it from there.

Some Interesting IQ Facts

Below you can find some interesting IQ facts:

• Our genetic makeup is responsible for 40-80% of our IQ

• The higher your IQ, the more likely it is that you will be a social person

• Eating junk food can decrease a child’s IQ

• Breastfeeding can increase IQ by 3-8 points

• The summer vacation can decrease a child’s IQ

• Those with an IQ between 75-90 have a higher chance of dropping out of school, going to jail, and living in poverty


• The higher a country’s average IQ, the higher their GDP will be

• Those with low IQs are more likely to think about committing suicide

• If you have an IQ of 115, you will be able to do any job

• The higher your IQ, the more confident you will be

The Bottom Line about IQ Tests

An IQ test is just one of the ways to see how intelligent a person is. When a doctor is trying to diagnose whether a person has an intellectual disability, they will not rely solely on an IQ test – they will make some additional observations and tests. The results of an IQ test should never be discounted, **but nor should they be used as sole indicator of someone’s intelligence. **
