How Your IQ is Measured

There is no single specific way to measure IQ. A variety of tests have been developed to assess intelligence, both in group settings and on an individual basis. All IQ tests aim to measure a person’s mental abilities in comparison to others within similar age groups or circumstances.

What an IQ Test Measures + The Different Types of IQ Tests

  1. Logical reasoning: spotting patterns, drawing conclusions.
  2. Verbal comprehension: understanding, analyzing, and using language.
  3. Working memory: remembering and using information over short periods.
  4. Processing speed: how fast you can take in and respond to information.
  5. Mathematical ability:  understanding numbers, solving numerical problems.
  6. Spatial reasoning:  visualizing objects in space (e.g. puzzles, 3D rotation).

Different Types of IQ-Tests

IQ tests aim to quantify certain types of intelligence, so they CANNOT define your full potential.

There are several, and they all focus on different things. The Wechsler Adult Intelligence Scale (WAIS) is the one most commonly used.

For kids and teenagers 16, there’s a similar version called the Wechsler Intelligence Scale for Children (WISC).

Other notable IQ Tests:

  • Stanford–Binet Intelligence Scale 
  • Raven’s Progressive Matrices 
  • Cattell Culture Fair Intelligence Test (CFIT)
  • Woodcock–Johnson Tests of Cognitive Abilities 
  • Universal Nonverbal Intelligence Test (UNIT)

IQ Score Range

40-54: Moderately impaired or delayed 

55-69: Mildly impared or delayed 

70-79: Borderline impared or delayed 

80-89: Low average 

90-109: Average

110-119: High average 

120-129: Superior 

130-144: Gifted or very advanced 

145-160: Very gifted or highly advanced

Note: Most people tend to fall in the low average-high average range (85-115). 

The Shocking Truth – What Your IQ Test Score Says About You… 

Nothing but your logical reasoning. What it doesn’t do is reflect your personality. It also doesn’t factor in your creativity, adaptability, feelings, emotions, or other traits that define you.

So if you think an IQ test should define your self-worth, think again.

And if you feel like you really need to reach a certain score on the IQ scale on an existential level, speaking from my own experience, the frequency with which you complete logic quizzes or IQ tests also plays a significant role.

Practice doesn’t always make perfect, but it certainly makes you better and helps stimulate your cognitive function.

A Few Tips on Scoring Higher on IQ Tests 

Practice Tests & Quizes

If you are serious on wanting to score higher on IQ tests, take practice tests and complete as many logic quizzes as possible. You can also get an exercise book for the IQ-Test section like visial logic or verbal logic, or one that combines them all, to maybe see where you are lacking. 

Other Tasks to Consider

Studies show that learning new languages, musical instruments, engaging in memory activities, reading regularly, can contribute to improving cognitive function and therefore potentially increasing your IQ-Test Score. 

Physical and Test Conditions

You should also take into consideration factors like your study or test environment, such as background noise, lighting, and even smells. How well-rested and hydrated you are can also make a difference. To help calm your nerves before the test, consider adopting a breathing technique that works for you.

A Short Outro 

So while IQ tests can be a useful tool for measuring a person’s intelligence in certain areas, they do not define who you are. There are definitely ways to improve your results over time, but the most important thing is not to pressure yourself or tie your self-worth to the outcome.
