In an era where exceptionalism is an expectation, we make a case for the average. In this instance, it’s for the average IQ score, specifically by age. And here’s what to familiarize yourself with: Show
Where do you stand on the spectrum? Let’s find out. IQ stands for ‘intelligence quotient’ — based on the German term “intelligenzquotient” — and was coined by the psychologist William Stern in 1912. It’s a numerical score that “indicates how far above, or how far below, his/her peer group an individual stands in mental ability,” as described by the largest and oldest high IQ society in the world, Mensa International. Very left-brain-based, it’s essentially a measurement of your ability to apply logical reasoning to solve problems. Mensa International explains that in adults, IQ is not really a quotient at all. Instead, it’s “an indication of how well one performs on mental tests, compared to others.” But that doesn’t mean your IQ is ‘better’ than that of a three-year-old. Or that of a centenarian for that matter. Your IQ is measured against your age too. How Are IQ Scores Calculated?The two-letter term, IQ, was initially measured as a ratio of mental age to chronological age multiplied by 100. For example, if you’re ten years old with a mental age of ten, your IQ would be 100. If your mental age is greater than your chronological age (let’s say, 15 instead of ten), then your IQ would be 150. Similarly, if your mental age was lower than your chronological age, then your IQ would be that, multiplied by 100. Index scales of modern IQ testsNowadays, IQ tests measure an adult’s intelligence based on these index scales:
Your points gained on these subtests are then combined to form an overall IQ score. Mensa International explains that when the concept of IQ was extended, one major development in its testing was the creation of group tests. Prior to this, people were tested individually by qualified psychologists. “The first group test was created for the US Army,” they point out. “They soon spread to schools, workplaces, and beyond, becoming one of psychology’s greatest popular successes and remain so to this day.” What’s the normal IQ range?There are several kinds of tests to calculate your IQ. The one most trusted and widely used is the Wechsler Adult Intelligence Scale (WAIS) – its fourth edition has the following score range:
So in a nutshell, when you score higher, the higher your “intelligence.” And if you’re curious as to where you stand on this intelligence scale, you can take the IQ test to find out.  What’s the Average IQ?The average IQ score for any age group is 100 — the center of the ‘normal’ range. Most IQ scores fall somewhere around this number. And as the scores move away from the normal range (100), there are fewer and fewer scores. This is known as standard deviation. You’re actually deemed to be within the ‘normal’ IQ range if you score anywhere between 85-115 on your test. Anything over that would be considered “exceptional,” like Marilyn vos Savant, who has the highest IQ score of 228 at the age of ten, according to the Guinness Book of Records. Likewise, anything under 100 would be regarded as “intellectually disabled.” Even for the lowest IQ, that’s harsh. What Is the Average IQ By Age?There isn’t any actual data on the average IQ by age. However, there’s some information about age groups, and here are the scores that denote ‘normal or average intelligence.’
It’s important to note that these scores by age should be taken with a pinch of salt. Given that the modern IQ tests, like WAIS-IV, consider a person’s age, it’s applicable to those 16 years old and above. The average IQ scores follow the bell curve, which you can find above. For those below that age, there’s a WAIS-V test that’s available. What’s the difference? For the fifth edition, there’s an extra index scale. While WAIS-IV looks at verbal reasoning, perceptual reasoning, working memory, and processing speed, WAIS-V adds fluid reasoning to the list. This measures a person’s ability to identify relationships among visual objects by completing a series of visual patterns. But essentially, the scoring system follows the same bell curve. What is the average American IQ?The average American IQ is 97.43, according to the World Population Review of 2022. This ranks them in 29th place after Belgium and before Norway. This seems to be quite far from their standings in 2017 where they were ranked number one in the Top 10 Countries with the Highest Intelligence Capital Index list. As for the country with the highest average IQ scores in the world? According to a 2019 study, that title belongs to the Japanese with Taiwanese and Singaporeans close behind. And they maintain that status in 2022. Why High/Low IQs Do NOT Measure IntelligenceWherever you fall on the IQ score spectrum, here’s the fact of life: there’s really no such thing as a good or bad IQ score. Why? Because your IQ is such a narrow measure of specific cognitive abilities. Frankly, it does a poor job of reflecting the vast world of your mental capacities and intellectual strengths as a unique individual. It also doesn’t take into account the different types of learning styles. New research in this field reveals that we may actually possess up to nine different types of intelligence. And you can develop each of them by learning to improve your brain functions. So what field of intelligence would you genuinely like to be sharper in? What’s something completely new you would like to learn? What cognitive abilities would serve you in living your best life? These are the questions that actually count. Unleash Your SuperbrainWhether you’d like to learn a new language or instrument, learn how to read faster, remember people’s names forever, or just boost your memory in general, it’s never too late. The truth is, your brain is a muscle and there’s nothing stopping you from training it to be stronger. What is the average IQ by age?These different types of intelligence show different patterns as you get older. Crystallized intelligence "averages 98 at ages 20–24, rises to 101 by ages 35–44, before declining to 100 (ages 45–54), then 98 (55–64), then 96 (65–69), then 93 (70–74), and 88 (75+)," says Kaufman.
What is Albert Einstein's IQ?Albert Einstein was a German-born theoretical physicist and philosopher of science whose estimated IQ scores range from 205 to 225 by different measures. He is best known for his mass–energy equivalence formula E = mc2 which has been called the world's most famous equation.
What IQ is genius?The first genius IQ score was around 140. That's about one in every 250 people. But one leading researcher in the 1940s suggested that a genius should have an IQ over 180. That's about one in every 2 million people.
How is IQ calculated?IQ, or intelligence quotient A number representing a person's reasoning ability. It's determined by dividing a person's score on a special test by his or her age, then multiplying by 100.
