"IQ tests assess cognitive abilities and generate a score that reflects how an individual's performance compares to others within the same age group. These tests evaluate a broad range of mental functions, including verbal reasoning, visual and spatial skills, processing speed, and pattern recognition."
IQ tests are standardized, with a mean score of 100 and a standard deviation of 15. Here are some IQ score ranges:
Above 130:Very Gifted
121-130:Gifted
111-120:Above Average Intelligence
90-110:Average Intelligence
80-89:Below Average Intelligence
70-79:Cognitively Impaired
Below 70:May indicate intellectual deficiency or mental retardation
IQ tests measure a variety of cognitive abilities, including:
Reasoning ability
Problem-solving ability
Ability to perceive relationships between things
Ability to store and retrieve information
Language ability
Memory ability
Why is the IQ scale Important?
The IQ scale is important as it provides a standardized way to measure cognitive abilities like reasoning and problem-solving. It helps in identifying learning needs, diagnosing mental conditions, guiding education and career decisions, and supporting research and policy-making. However, IQ is only one aspect of intelligence and does not capture creativity, emotional skills, or practical knowledge.
What is a Good IQ Score for Your Age?
An IQ score of 90 or higher is considered good for individuals of any age. The average score ranges from 90 to 110. Scores below 90 are classified as low IQ, while those exceeding 110 are regarded as genius.
Does IQ Increase with Age?
For the most part, IQ does not increase with age. The scale reflects results based on the test taker's age. So, as long as the person is growing chronologically and mentally in the same upward trend, their IQ should be the same for their entire life.
What Causes IQ to Drop?
A decrease in IQ is usually due to some form of mental trauma, in most cases physically, but in other cases mentally. There is some evidence to suggest environmental factors like an increase in online time, changes in nutrition, the manner of education, and less reading in society overall.
Is Your IQ Genetic or Learned?
Intelligence seems to be largely genetic, though some environmental factors can affect this. Studies on sets of twins have shown that about 60% of the factors determining a person's intelligence and aptitude in learning environments come from genetics.
When Does Your IQ Peak?
As mentioned, most people should have a similar IQ level throughout their lifetime. However, it is possible that children and young teens can grow their IQ as they continue to learn in educational systems and develop biologically. When you become an adult, your IQ tends to peak at about 20 years old.
