What are IQ tests?

Intelligence quotient (IQ) roughly calculates your intelligence level.

Sets encompass a series of tests that are standardized and cover a wide range of topics such as:

  • Logic
  • Visual attention
  • Spatial recognition
  • Classification
  • Analogical and pattern-driven questions

On an intelligence test, questions will be asked that will assess various categories such as:

  • Working memory
  • Verbal comprehension
  • Processing speed
  • Perceptual reasoning

All these individual scores are added together to calculate your overall IQ. The IQ is calculated as the difference between your test score and the average test score of people your age.

IQ is regarded as a rough metric because:

  • It measures general intelligence.
  • Age is used to determine IQ scores.
  • One general score is determined.
  • It is moderately predictive of job performance.
  • Its most common uses are research and education.

An IQ score is a numerical representation of a person’s intelligence on a scale of test results that has been normalized. The mean score on most modern tests is set to 100. Individuals are typically stronger in one area than the other, so combining these scores can help identify intelligence.

Scores

  • IQ scores ranging from 90 to 109 indicate intelligence that is normal to above average.
  • Individual adults typically score between 70 and 130, with a theoretical average of 100.
  • A score of more than 130 indicates that you are higher than the average population, whereas a score of less than 70 indicates that you are lower than the average population.
  • Scores ranging from 110 to 119 indicate superior or above-average intelligence.
  • Anyone with an IQ between 120 and 140 is considered gifted or has superintelligence.
  • People who have an IQ of 140 are geniuses or near geniuses such as Dr. Evangelos Katsioulis.
  • Scores ranging from 80 to 89 indicate below average.
  • Scores ranging from 70 to 79 indicate a deficiency or low level.
  • Any IQ less than 70 is considered low.

The most reliable IQ tests are those administered by a trained psychologist. These outcomes are difficult to replicate online.

Most reliable IQ tests

  • Wechsler Adult Intelligence Scale (WAIS):
    • It is a test used to assess cognitive ability. Tests have been modified numerous times and are still widely used today.
    • WAIS is regarded as one of the most reliable adult IQ tests. WAIS is designed for people older than 16 years.
    • Although based on the same skills, free online versions of Wechsler typically are not as reliable as official WAIS.
  • Mensa practice test:
    • The practice test asks questions that correspond to skills commonly tested by IQ assessments and provides an equivalent score that corresponds to your IQ range.
    • This test gives you an idea of how well you'll perform on the official admissions exam. Mensa is the largest and oldest high-IQ society in the world.
    • To be eligible to join Mensa, members must score in the 98th percentile or higher on a supervised, standardized intelligence test.
  • Stanford–Binet Intelligence Scale (SBIS):
    • It is now one of the most widely used and respected IQ tests.
    • In its most recent edition, SBIS is divided into 10 subtests, each of which takes about five minutes to complete.
    • Each of the five cognitive ability factors is thoroughly covered by the subtests.

Can you improve your IQ?

Although the science is divided on whether you can increase your intelligence quotient (IQ), research does appear to suggest that certain brain-training activities can help you do so. 

Improving your memory, executive control, and visuospatial reasoning can all help increase your intelligence.

Various methods by which you may be able to improve both your crystallized and fluid intelligence include:

  • Exercise regularly
  • Get enough sleep
  • Meditate
  • Eat and drink nutrient-rich foods that include antioxidants
  • Learn and play a musical instrument
  • Read a wide variety of books
  • Learn a new language
  • Solve crosswords or sudoku regularly

Keep your mind active if you want to keep your IQ score high as you get older. It can help you maintain your cognitive abilities.

Degenerative brain conditions such as Alzheimer’s disease may affect your IQ. It is a good idea to engage in problem-solving activities such as bingo, Sudoku, and jigsaw puzzles regularly.
