Introduction
IQ tests have long been a subject of debate in terms of measuring intelligence. Although they are widely used and accepted as a standard method for assessing cognitive ability, they have limitations. There are many factors that come into play when measuring intelligence, and some states may score higher on average IQ tests than others, due to factors beyond their population’s actual intelligence. Some studies have shown that the results of IQ tests may be influenced by culture, socioeconomic status, or other environmental factors, which can lead to inaccuracies in measuring intelligence.
Despite these limitations, IQ tests remain one of the most commonly used methods for measuring intelligence in the US. The average IQ scores in the US are calculated based on the scores of a standardized IQ test taken by a representative sample of the population. This data is used to determine the national average IQ score, which can be compared to the scores of other countries around the world.

Average IQ in USA
The American average IQ is 98, according to the latest data from 2022. Historically, the average IQ score in the US has been rising steadily, with an average increase of about 3 points per decade. This increase is attributed to factors such as improved education, healthcare, and nutrition. Despite this trend, there is a considerable variation in average IQ scores between states.
Looking at the average IQ by state gives us a better perspective on the disparities in IQ scores in the US. According to the data from the National Assessment of Educational Progress, Massachusetts has the highest average IQ score at 104.3, followed closely by New Hampshire with a score of 104.2. On the other hand, Mississippi has the lowest average IQ score at 94.2.
The reasons for these differences are complex and multifaceted. Some states have higher levels of education and access to resources such as good schools, libraries, and other educational institutions, which can contribute to higher average IQ scores. Other factors such as poverty, race, and socio-economic status can also play a role in determining average IQ scores.
States with Highest IQ
The states with the highest IQ are Massachusetts, New Hampshire, North Dakota, Vermont, Minnesota, Maine, Montana, Iowa, Connecticut, and Wisconsin. Many theories have tried to explain why some states are “smarter” than others, including proposals that argue that colder climates could favor higher IQs. Other factors like genetics may play a role in the development of an individual’s intelligence. Yet, these propositions do not provide the full picture of why Massachusetts or New Hampshire have higher IQ scores. A crucial element to look at is education: it is proven that easy and affordable access to robust and efficient education is key in explaining IQ variations. The states with the highest IQs all have great education systems and programs. Massachusetts for example is home to internationally-recognized universities including Harvard University, the Massachusetts Institute of Technology (MIT), and Boston University. As for New Hampshire, the state has one of the highest percentages of adults who have a high school diploma.
Massachusetts, with an average IQ of 104.3, is the state with the highest IQ in the United States, but only by 0.1, as New Hampshire is the second state with the highest IQ, with an IQ score of 104.2. North Dakota is the third state with the highest IQ with a score of 103.3 and only 0.5 points above Vermont, placed fourth highest IQ state, with an average IQ of 103.8. Minnesota is the fifth state with the highest IQ, holding an average IQ score of 103.7, only 0.1 point below that of fourth-place Vermont. Both Maine and Montana, the sixth and seventh states with the highest IQ, have an average IQ of 103.4. The states of Iowa and Connecticut, ranked eighth and ninth states with the highest IQ, both holding an average IQ score of 103.1. Wisconsin has the tenth highest IQ by state, with an IQ score of 102.9.

The ten states with the highest IQ are :
1. Massachusetts – 104.3
2. New Hampshire – 104.2
3. North Dakota – 103.8
4. Vermont – 103.8
5. Minnesota – 103.7

8. Iowa – 103.2
9. Connecticut – 103.1
10. Wisconsin – 102.9
State with Highest IQ
Massachusetts is the state with the highest IQ, with an average IQ of 104.3. This number is well above the national average, which indicates that the intellectual prowess and academic achievement of Massachusetts citizens are at a very high level. The state has been known as a leader in education since it was founded, and its culture and society reflect this emphasis on knowledge and learning. Massachusetts boasts some of the best universities around, such as Harvard, MIT, and Tufts, that attract some of the most brilliant minds from all over the world. In addition, its public school system consistently ranks among the highest-performing schools in America. Massachusetts also has plenty of cultural resources to further enhance its intellectual appeal, including numerous libraries, museums, galleries, symphonies, and other sources of intellectual stimulation.
Lowest IQ States
The states with the lowest IQs are Mississippi, Louisiana, California, Hawaii, Alabama, New Mexico, Nevada, Arizona, Arkansas, and Tennessee. Various factors may favor lower IQ, such as education, wealth, nutrition, and public policies. Health is another key factor. Indeed, a recent study showed that the development of the brain during childhood consumes close to 90% of a newborn calorie intake. If this newborn is contaminated by an infectious disease, part of its energy will be directed to fighting the disease, and not to develop the brain. All states with the lowest IQs in the U.S. have high levels of infectious disease as well. This suggests that infectious disease could be one of the primary causes of low IQ.
The state of Mississippi, with an IQ score of 94.2, has the lowest IQ in the United States. The second state with the lowest IQ in the country is Louisiana with an average IQ score of 95.3, this is only 0.2 points less than California, which has an average IQ of 95.5 and places the state in the third position for states with lowest IQ. Hawaii is the fourth state with the lowest IQ in the US, with an IQ score of 95.6. Both Alabama and New Mexico, the fifth and sixth states with the lowest IQ, have an average IQ score of 95.7. Nevada is the seventh state with the lowest IQ, with an average IQ of 96.5. The eighth state with the lowest IQ is the state of Arizona, with an average IQ score of 97.4 and by a 0.1 difference, Arkansas takes ninth place with a score of 97.5. Tennessee is the tenth state with lowest IQ, with an average IQ of 97.7.

2. Louisiana – 95.3
3. California – 95.5
4. Hawaii – 95.6
5. Alabama – 95.7
6. New Mexico – 95.7
7. Nevada – 96.5
8. Arizona – 97.4
9. Arkansas – 97.5
10. Tennessee – 97.7
State With the Lowest IQ
The state with the lowest IQ is Mississippi, with an average IQ score of 94.2. This score lags substantially behind the national average of 98 and puts Mississippi at an educational disadvantage when compared to other states. According to recent statistics, roughly 14% of adults in Mississippi do not possess a high school diploma, indicating that educational attainment is low in the state. Furthermore, survey data showed that only 23% of Mississippi adults had earned an associate degree or higher, again signifying a lack of education and training among its citizens. This could be attributed to a variety of factors including limited access to quality schools and resources or inadequate financial support for students seeking higher education. Additionally, research has suggested that poor health outcomes among residents may also contribute to Mississippi’s lower-than-average IQ scores.
Source
The data used on this page for the average IQ by state in the US comes from a study conducted by researchers using the National Assessment of Educational Progress (NAEP) standardized tests for reading and math. These tests are administered to a sample of public school children in each of the 50 states. The researchers estimated the average IQ for each state based on the scores of these standardized tests. The NAEP tests are considered to be highly reliable measures of student achievement, and there is substantial technical literature on these measures.
This data has been used in various studies to provide insights into educational attainment, student performance, and other indicators of academic achievement. But while this data is useful for understanding trends in education and achievement across states, it is important to remember that IQ is just one aspect of intelligence, and does not capture the full range of intellectual abilities or potential of an individual or a state. Additionally, the use of standardized test scores to estimate IQ can be controversial, as some argue that these tests may be influenced by factors such as socio-economic status, cultural bias, and other environmental factors that may affect performance.
