This article explores the average American IQ, its variations across states, and how it compares globally while addressing the concept’s limitations and broader implications for understanding human intelligence.
Intelligence Quotient (IQ) measures a person’s reasoning ability compared to the statistical norm for their age group. The average IQ of a region can be determined by examining statistical data on various individuals from that region or country.
Despite controversies, IQ scores remain a widely used metric for estimating intellectual potential. That being said, let us get straight to the details.
Average IQ In The United States
According to recent data, the national average IQ score for the United States is approximately 98. This places the US slightly below the standardized IQ test mean of 100. However, the US ranks globally above the average, estimated at around 82-85.
Over time, IQ scores in the US have been increasing, a phenomenon known as the Flynn effect (Named after Dr. Flynn in the picture above, who was credited with discovering it).
This increase is attributed to factors such as improved nutrition, better education, and enhanced cognitive stimulation from technology.
However, some recent studies suggest this trend may be slowing or even reversing in developed countries, including the US.

The Concept Of IQ
The concept of IQ dates back to the early 20th century when French psychologist Alfred Binet developed the first intelligence test. David Wechsler then standardized the modern IQ test later in the 1930s.
IQ is typically measured through standardized tests assessing various cognitive abilities, including verbal comprehension, perceptual reasoning, working memory, and processing speed.
Despite its widespread use, IQ testing is heavily criticized!
These include concerns about cultural bias, the narrow focus on specific cognitive abilities, and the inability to measure other forms of intelligence, such as emotional or creative intelligence.
Critics argue that IQ tests may not accurately reflect real-world problem-solving abilities or success in diverse cultural contexts.
Is It Possible To Increase Your IQ Score?
Disclaimer: Significant long-term increases are challenging to achieve.
While genetics partly influences IQ, research suggests it can be improved to some extent.
Here are a few recommendations to help you increase your IQ.
- Engaging in mentally stimulating activities
- Pursuing education
- Maintaining good physical health
- Indulging in activities that help reduce stress can enhance cognitive abilities and IQ scores.
Conclusion: The Average American Iq Is 98, Placing The U.S. 18th Globally
The average American IQ of 98 places the United States slightly below the standardized mean but above the global average.
The variations in IQ across states highlight the influence of factors such as education, socioeconomic conditions, and environmental influences on cognitive development.
While IQ tests provide valuable insights into specific cognitive abilities, they should not be considered the sole measure of intelligence or potential.
Therefore, the future of IQ testing in America may evolve into more comprehensive assessments that account for diverse forms of intelligence and cultural backgrounds.
Ultimately, it’s crucial to recognize that human intelligence is multifaceted and that IQ scores are just one piece of a much larger puzzle in understanding cognitive capabilities and potential.
