What is the normal human IQ?
Disease description:
My child is not doing well in school, always forgets things, and cannot seem to learn anything. I am worried about his low intelligence and am planning to take him for an IQ test. May I ask what is considered a normal IQ score for an average person?
Doctor's answer (1)
Dr. Huang Shichang
The range of intelligence quotient (IQ) in healthy individuals is broad, but most people's IQ scores fall between 90 and 110. This range is considered normal or average for IQ. IQ is a relative measure of an individual's intellectual development level, assessed through standardized testing tools that evaluate multiple domains, including language comprehension, mathematical ability, logical reasoning, and spatial cognition.
IQ is not the sole criterion for measuring a person's overall abilities and is also influenced by various factors such as personal interests, experiences, and environment. Therefore, even if an IQ score falls outside the normal range, it should not be used as the sole determinant of a person's abilities and potential.
However, if there are genuine concerns, it is recommended to seek immediate medical consultation for professional evaluation by a qualified physician.
