What is the Average IQ in the USA: What Does It Mean to Have Average Intelligence?

Have you ever wondered if you're "smart enough"? Or if your intelligence quotient (IQ) score is above average? You're not alone!

In the United States, IQ scores are widely used to gauge intelligence levels. But what does it mean to have an average intelligence quotient?

An average IQ score (between 85 and 115) signifies a typical range for your cognitive abilities compared to others. However, this single number cannot fully encapsulate one's intellectual capacity and potential. Intelligence encompasses problem-solving, emotional intelligence, creativity, determination, mental strength, and more.

Sadly, society often places people with genius IQs on such a pedestal that many people with average IQs feel inadequate or like failures. However, it's important to remember that countless successful individuals have thrived with average IQ scores. For instance, former US President Harry S. Truman, business magnate Richard Branson, and legendary boxer Muhammad Ali all achieved remarkable success despite having IQs in the average range.

In this article, we'll unpack the concept of IQ scores in the USA—what the numbers represent, why this metric matters (and why it doesn't), how to nurture your unique intellectual strengths beyond just a score, and provide examples of successful people with average intelligence scores.

What is an Average IQ Score?

IQ stands for intelligence quotient. An average IQ score means your result on the intelligence test was typical or normal compared to most other test takers. Specifically, if your score lands between 85 and 115, it would be considered in the average range.

When scoring IQ tests, all test takers' median (middle) score is set at 100 as a reference point. The scores then follow a bell curve distribution. About 68% of people will have scores bunched around that middle 100 score, between 85 and 115.

So, an IQ score of 85-115 implies your cognitive abilities and test performance were pretty much in the middle compared to others who took the same test. It doesn't mean you have low, high, or average intelligence; it's just that your mental skills were standard or enough for that specific IQ exam.

Why Do IQ Tests Set 100 as Average Intelligence?

The decision to use 100 as the average IQ score ensures the scoring is easier for you to understand and interpret. The 100 IQ score serves as a middle reference point against which to measure your performance.

Using 100 as the average allows the scores to be distributed neatly— about half of the test takers will score above 100 and the other half below.

Additionally, setting the average IQ at 100, with most scores falling within about 15 points above or below, allows for a wide range of IQ scores while keeping the numbers simple to comprehend.

Scores much higher or lower than that average range of 85-115 become increasingly rare and outstanding. For example, an IQ of 130 only occurs in about 2% of people.

However, you need to understand that a score of 100 doesn't mean "average intelligence" in a definite sense. It's just the central benchmark number that test makers chose to represent the middle point for that specific IQ test's scoring system.

What is the Average IQ in the United States?

In the US, approximately two-thirds of the population is estimated to have an average IQ between 85 and 115. Recent studies have estimated the average IQ range for Americans to be around 97 to 98 (based on data from the National Assessment of Educational Progress (NAEP). However, it's important to note that this is just an approximate figure, and individual IQ scores can vary considerably. 

Several key factors, including educational level, socioeconomic and environmental factors, ethnicity and culture, and health and nutrition, can influence someone's performance on an intelligence test and impact their score.

So, while 97-98 may represent the average score nationwide, there is substantial variability within the US population based on demographics and environmental factors. An individual's IQ score paints just one part of the overall intelligence picture.

How Does IQ in the United States Compare with Global Average IQ Scores?

The global average IQ is estimated to be around 100, similar to the average score in the United States. However, we should compare national IQ scores with caution. Cultural differences and historical contexts can all affect these comparisons and limit their accuracy.

Additionally, there are variations in the IQ tests used across different countries as there are no typically standardized tests. Comparing average national IQ scores can also be misleading, as there is significant variation within each nation's population, and focusing on these comparisons can oversimplify the complex realities of intelligence distribution.

Moving Beyond IQ Numbers: What Really Matters?

IQ tests assess specific cognitive abilities but provide a limited view of your full intellectual potential. As such, they may not accurately measure intelligence. Qualities like creativity, emotional intelligence, determination, practical problem-solving abilities, and social skills are significant in cultivating a well-rounded mind.

However, taking an intelligence quotient (IQ) test can still offer valuable insights into your strengths, abilities to develop further, and how you approach specific challenges. Rather than fixating on the IQ score alone, use it as a data point to better understand and nurture your unique intellectual landscape.

The IQ estimates provided for the historical figures, celebrities, and successful people on this list are based on various secondary sources, including biographies, interviews, and analyses conducted by psychologists and researchers. 

Since most of these individuals have not taken formal IQ tests, their estimated scores are derived from assessments of their educational backgrounds, accomplishments, and anecdotal evidence about their intellectual abilities. These estimates are not definitive but offer a general idea of where they may fall on the intelligence scale. 

Ultimately, they emphasize that a numerical score does not solely determine one's potential for success or impact in their chosen field.

These individuals serve as reminders that while IQ can offer some insights into one's cognitive capabilities, it does not define success. Resilience, vision, dedication, job satisfaction (in a career you love), and passion often play a more significant role in achieving one's goals and impacting the world.

They are living proof that you don't have to be an "Einstein" to make your mark on the world!

IQ Doesn't Define You: Average IQ Scores FAQs

Understanding average IQ scores in the USA can provide some context, but it shouldn't define your intelligence or what you can achieve. 

There's so much more to your intellectual potential than a single number. Embrace your unique strengths, explore your interests, and keep fostering your love of learning.

Let's close with frequently asked questions about average intelligence scores.

Is an IQ Score of 100 Bad or Good?

An intelligence quotient score of around 100 is neither bad nor good— it is simply a statistical average used for comparison. Having an average IQ doesn't make someone more or less intelligent overall. IQ tests only measure specific cognitive abilities at one point in time.

Is an IQ of 80 Good?

An IQ score of 80 falls in the below-average range, but it doesn't define your intelligence or potential. Everyone has unique strengths and abilities that intelligence tests can't fully measure. With the right learning environment and support you can thrive and reach your goals.

Is an IQ of 100 Good?

An average score of 100 means your cognitive abilities are average compared to the population. But "average" doesn't mean limited— it simply sets a useful baseline. Everyone has a mix of strengths and weaknesses. Focus on developing your talents and believing in your capability to learn and grow.

Is an IQ of 110 Good?

Yes, an IQ of 110 is considered above average when 100 is used as the median average IQ score. It falls within the range of 85 to 115, which encompasses most of the population and indicates solid cognitive abilities. People with this score often perform well in educational and professional settings.

Is an IQ of 120 Good?

A 120 IQ is considered a high score that suggests above-average cognitive abilities for analytical thinking and academics. However, a high IQ alone doesn't guarantee success. Traits like creativity, drive, resilience, and emotional intelligence play vital roles too. Nurture all your intellectual gifts to reach your full potential.
