The vast majority of people in the United States have I.Q.s between 80 and 120, with an I.Q. of 100 considered average. To be diagnosed as having mental retardation, a person must have an I.Q. below 70-75, i.e. significantly below average.
Scores between 80 and 89 are classified as low average. So in most cases, if you receive an IQ score of around 100, then you have what is considered an average IQ. Don't worry—you are in good company. Most people score within one standard deviation of this average.
90-110 (median plus or minus 10): Average IQ. 80-90: Below Average IQ. 70 to 80: Borderline. Below 70: May indicate intellectual deficiency or mental retardation.
What is a normal IQ for a child? Though there are different average IQ scores for various age levels, the average for most children is 100, though scores will vary. Most children will fall between 80 and 120 if they are tested when they have a basic understanding of cognitive concepts.
Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults.
Like, is Elon Musk a genius? It answered, Elon Musk's IQ is reported to be 155, which is very high compared to the average of 100.
But genetics can explain the wide range of possible IQs too because so many different genes are involved in developing and running a brain. It is possible, for example, to inherit all the higher IQ genes from each parent and leave the lower IQ ones behind. Now the child will be brighter than the parent.
What's the lowest IQ ever? The lowest IQ ever would be 0. However, no one has ever scored that. Scores below 75 usually indicate a cognitive disability.
70 to 84: Borderline mental disability. 85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted.
110 - 119 is "superior intelligence", while 90 - 109 is "normal or average intelligence". An IQ between 80 and 89 suggests "dullness", while a score of 70 to 79 is classed as "borderline deficiency".
The average IQ of an 11-year-old is 85-100, which is also the average IQ for any age group. IQ, or intelligence quotient, is a measure of cognitive ability that is designed to assess a person's intelligence relative to others of the same age.
Does an individual's IQ change with age? An individual's IQ does not change with age. In other words: if you did an IQ test now and then another one in 10 years' time, your IQ score will probably be very similar. This is because IQ is always measured relative to other people your age.
Plot. In 1981, a man named Forrest Gump recounts his life story to strangers who happen to sit next to him at a bus stop. As a boy in 1956, Forrest has an IQ of 75 and is fitted with leg braces to correct a curved spine.
Mark Zuckerberg: The co-founder of Facebook, Zuckerberg has an IQ estimated to be around 152. Elon Musk: The founder of SpaceX, Tesla, Neuralink, and other companies, Musk has an IQ estimated to be around 155.
Kanye says he scored a 133 on Mensa IQ test, compares his brain to women's bodies.
This means their thinking and reasoning skills are well above their same-aged peers. To be classified as gifted, most education departments require children to have an IQ score at or above 130 on a standardised test administered by a psychologist.
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.
IQ scores between 90 and 109 indicate a normal range or average intelligence. Individual adults usually score somewhere in between the 70-130 range, with 100 being the theoretical average.
Scores of 80-89 are considered to be in the Low Average range of intellectual functioning. Scores of 90-109 are Average. Scores of 110-119 are High Average. An IQ of 125 is considered by many schools to be “gifted.” Scores of 120-129 are Superior.
The average IQ difference between a parent and his (or her) child is the same as the difference between siblings-that is, about 12 IQ points. The difference between a child and the average of both of his parents' IQ's is about 10 points.
