What is an &#8220;average&#8221; IQ? What does a score of 100 mean? Is it possible to improve one&#8217;s IQ? What are the limitations of this measure?

Origins and Definition<\/h2>\n<pee>The intelligence quotient (IQ) is a standardized measure aimed at assessing an individual&#8217;s general cognitive abilities compared to those of a reference group of the same age. It was developed in the early 20th century by the French psychologist Alfred Binet, commissioned by the government to identify children needing special educational support. Binet&#8217;s measure was based on &#8220;mental age&#8221; \u2014 if an 8-year-old child succeeded in tasks typically passed by 10-year-old children, their mental age was considered to be 10 years.<\/pee>\n<pee>The initial formula for IQ (mental age \/ chronological age \u00d7 100) was replaced in the 1960s by &#8220;deviation IQ&#8221; \u2014 the current score, which no longer compares to a mental age but positions an individual&#8217;s result relative to the distribution of results of their age group. It is this deviation IQ that all modern tests measure.<\/pee>\n<h3>How is IQ set at 100?<\/h3>\n<pee>The average IQ is set at 100 by construction \u2014 it is a statistical convention, not a biological reality. During the standardization (or &#8220;normalization&#8221;) of an IQ test, the designers administer it to a large representative sample of the population, calculate the median performance of each age group, and assign it the score of 100. The scores of other individuals are then positioned relative to this median according to a normal distribution (bell curve), with a standard deviation of 15 points.<\/pee>\n<div class=\"highlight-box\">\n<h4>\ud83d\udcca The normal distribution of IQ in the population<\/h4>\n<pee>IQ scores follow a normal distribution (bell curve) with an average of 100 and a standard deviation of 15.

It is closely related to crystallized intelligence \u2014 accumulated knowledge \u2014 and tends to be stable or progress with age and education.<\/pee>\n    <\/div>\n<div class=\"method-card teal\">\n<div class=\"method-badge badge-green\">\ud83e\udde9 Perceptual \/ fluid reasoning<\/div>\n<h4>Non-verbal logical reasoning, matrices, patterns<\/h4>\n<pee>This factor evaluates the ability to reason with visual information and patterns, to identify rules in sequences, and to solve new problems without relying on acquired knowledge. It is the measure closest to fluid intelligence \u2014 and the one that declines most sharply with age.<\/pee>\n    <\/div>\n<div class=\"method-card yellow\">\n<div class=\"method-badge badge-yellow\">\ud83d\udd22 Working memory<\/div>\n<h4>Retaining and manipulating information in real time<\/h4>\n<pee>Memorizing a sequence of numbers and repeating it backward, mentally performing an arithmetic operation while retaining other information \u2014 this factor evaluates the ability to maintain and manipulate information in short-term memory. It is closely related to performance in academic and professional learning.<\/pee>\n    <\/div>\n<div class=\"method-card rose\">\n<div class=\"method-badge badge-rose\">\u26a1 Processing speed<\/div>\n<h4>Speed and efficiency of cognitive processing<\/h4>\n<pee>This factor evaluates how quickly the brain processes simple information \u2014 copying symbols, identifying similarities in a series. It is one of the first to decline with age, but also one of the most sensitive to fatigue and acute stress.<\/pee>\n    <\/div>\n<h2>The Flynn effect: why does the average IQ increase?<\/h2>\n<pee>One of the most fascinating \u2014 and most discussed \u2014 phenomena in psychometrics is what New Zealand researcher James Flynn documented in the 1980s: the average IQ increases by about 3 points per decade since tests have existed. This phenomenon, called the &#8220;Flynn effect,&#8221; is robust and has been observed in many countries.<\/pee>\n<pee>What explains it? Not genetic change (too slow to produce this effect in a few decades). The most serious hypotheses point to: better nutrition during childhood (especially in micronutrients), reduced exposure to neurological toxins (like lead), longer and more intensive schooling, and \u2014 probably the most important factor \u2014 increasing familiarity with abstract thinking and reasoning modes required by IQ tests.<\/pee>\n<div class=\"tip-box\">\n<h4>\ud83d\udca1 What the Flynn effect teaches us about IQ<\/h4>\n<pee>If the average IQ increases by 3 points per decade, it means that a score of 100 in 2024 does not correspond exactly to the same level of performance as a score of 100 in 1980. Tests are regularly re-normed to keep the average at 100. This also illustrates that performance on IQ tests is influenced by the environment \u2014 schooling, nutrition, cognitive stimulation \u2014 and not just by &#8220;innate&#8221; abilities.<\/pee>\n    <\/div>\n<h2>Can IQ increase or decrease?<\/h2>\n<pee>This is one of the most frequently asked questions \u2014 and the answer is nuanced. IQ is relatively stable in adulthood under normal conditions. But &#8220;relatively stable&#8221; does not mean &#8220;completely fixed.&#8221; Factors can modify performance on IQ tests:<\/pee>\n<div class=\"checklist\">\n<h4>\u2714 Factors that can affect IQ test results<\/h4>\n<ul>\n<li><strong>Education and intellectual stimulation:<\/strong> quality schooling and environments rich in cognitive stimulation improve cognitive performance<\/li>\n<li><strong>Health status:<\/strong> neurological diseases, nutritional deficiencies, sleep disorders, and chronic stress degrade cognitive performance<\/li>\n<li><strong>Aging:<\/strong> some components (fluid reasoning, processing speed) decline with age, while others (verbal comprehension) remain stable or even improve<\/li>\n<li><strong>Specific test training:<\/strong> familiarizing oneself with test formats can improve scores by 5 to 15 points \u2014 without necessarily improving underlying cognitive abilities<\/li>\n<li><strong>Motivation and emotional state on test day:<\/strong> anxiety, fatigue, or lack of motivation can significantly depress scores<\/li>\n<\/ul><\/div>\n<h3>Can cognitive training improve IQ?<\/h3>\n<pee>The research on this point is nuanced. Cognitive training programs (notably intensive working memory training) have shown improvements on trained tasks, and sometimes transfers to related tasks. More recent studies have found modest effects on components of fluid reasoning with intensive and prolonged programs. The effect on &#8220;IQ&#8221; in the broad sense remains debated \u2014 but the improvement of specific cognitive functions (memory, attention, executive functions) is well documented.<\/pee>\n<pee>DYNSEO offers cognitive stimulation applications tailored to each age to support this training: <a href=\"https:\/\/www.dynseo.com\/en\/brain-games-apps\/clint-brain-games-for-adults\/\" target=\"_blank\"><strong>CLINT for adults<\/strong><\/a>, <a href=\"https:\/\/www.dynseo.com\/jeux-de-memoire\/coco-jeux-enfants\/\" target=\"_blank\"><strong>COCO for children aged 5 to 10<\/strong><\/a>, and the <a href=\"https:\/\/www.dynseo.com\/en\/coach-ia-english\/\" target=\"_blank\"><strong>AI Coach<\/strong><\/a> for personalized support.<\/pee>\n<h2>The limits of IQ: what it does not measure<\/h2>\n<pee>IQ is a powerful and well-validated psychometric tool for what it measures. But it is crucial to understand its limits to avoid overinterpretation.<\/pee>\n<div class=\"method-card rose\">\n<div class=\"method-badge badge-rose\">\u26a0\ufe0f Limit 1<\/div>\n<h4>IQ does not measure all forms of intelligence<\/h4>\n<pee>Howard Gardner proposed in 1983 his theory of multiple intelligences \u2014 musical, bodily-kinesthetic, interpersonal, intrapersonal, naturalistic \u2014 which are not or are poorly measured by standard IQ tests. Robert Sternberg introduced the notion of practical intelligence (adaptive know-how in the real world) and creative intelligence. These theories are discussed in cognitive sciences, but they remind us that IQ captures only a part of human abilities.<\/pee>\n    <\/div>\n<div class=\"method-card yellow\">\n<div class=\"method-badge badge-yellow\">\u26a0\ufe0f Limit 2<\/div>\n<h4>IQ is not destiny<\/h4>\n<pee>An IQ score does not predict individual success or happiness. Factors such as perseverance, curiosity, creativity, emotional intelligence, socioeconomic conditions, the quality of education received, luck, and health play an equally important role in life trajectories. Studies show that &#8220;deliberate practice&#8221; (sustained effort over the long term) often predicts success better than IQ.<\/pee>\n    <\/div>\n<div class=\"method-card teal\">\n<div class=\"method-badge badge-green\">\u26a0\ufe0f Limit 3<\/div>\n<h4>IQ can be affected by cultural biases<\/h4>\n<pee>IQ tests were developed in specific cultural contexts, and some items may favor people familiar with certain cultural, linguistic, or educational codes. Significant efforts have been made to reduce these biases in modern versions of the tests, but they are not completely eliminated. A low score does not necessarily mean limited cognitive abilities.<\/pee>\n    <\/div>\n<h2>Average IQ and context: international comparisons<\/h2>\n<pee>Studies have attempted to compare average IQs between countries and regions. These comparisons are delicate \u2014 tests are not always equivalent from one cultural context to another, testing conditions vary, and sample selection biases are significant. Available data suggest significant variations between countries, largely correlated with the level of economic development, the quality of educational systems, access to healthcare, and exposure to toxic factors such as lead. What is clear: the differences observed between groups are mostly environmental in nature, not genetic.<\/pee>\n<h2>IQ and High Intellectual Potential (HIP)<\/h2>\n<pee>An IQ of 130 or higher conventionally defines High Intellectual Potential (HIP) \u2014 which represents about 2 to 2.5% of the population. People with HIP may exhibit specific characteristics that go beyond simple cognitive performance: tree-like thinking, sensory hyperesthesia, emotional hypersensitivity, perfectionism, feelings of social mismatch. HIP is not without challenges: school boredom, difficulty finding peers of similar level, and sometimes associated psychological distress are realities for some of these individuals.<\/pee>\n<div class=\"quote-box\">\n        <pee>&#8220;A high IQ is like a powerful engine \u2014 it says nothing about the direction one is taking, nor about how one drives.&#8221;<\/pee>\n<div class=\"author\">\u2014 Adapted from research on intelligence and success (Sternberg, 2019)<\/div>\n<\/p><\/div>\n<h2>Beyond IQ: how to assess your cognitive profile?<\/h2>\n<pee>Rather than focusing on a single number, the most useful approach is to explore your cognitive profile \u2014 the specific strengths and weaknesses in different cognitive areas.

They can provide an approximate indication, but with a significant margin of error. A validated IQ test (WAIS, Stanford-Binet) is always taken in the presence of a professional under standardized conditions.<\/pee>\n    <\/div>\n<div class=\"faq-item\">\n<h4>Can a child have a measured IQ? From what age?<\/h4>\n<pee>Yes. Validated IQ tests exist for children from the age of 2 and a half (WPPSI for young children, WISC-V from 6 years old). These assessments are conducted by neuropsychologists or specialized psychologists, most often in the context of a school evaluation, suspicion of giftedness, or assessment of learning disorders.<\/pee>\n    <\/div>\n<div class=\"faq-item\">\n<h4>What is the link between IQ and neurodevelopmental disorders such as ADHD or dyslexia?<\/h4>\n<pee>Neurodevelopmental disorders (ADHD, dyslexia, dyscalculia, autism) are not defined by a low IQ. Individuals with ADHD or dyslexia can have a very high IQ. What characterizes these disorders is a disharmony in the cognitive profile \u2014 marked strengths and difficulties in specific areas, often associated with very variable scores between the different sub-tests of an IQ assessment. This is why analyzing the intra-individual profile is often more important than the overall score.<\/pee>\n    <\/div>\n<div class=\"conclusion\">\n<h2>Conclusion: IQ, a tool among others to understand intelligence<\/h2>\n<pee>IQ is a useful and scientifically validated indicator for certain questions \u2014 particularly in clinical settings, special education, and research on cognitive abilities. The average IQ of 100 is a statistical convention that allows situating an individual relative to their age group, but it says little about their value, potential for development, or ability to thrive and succeed in life.<\/pee>\n        <pee>Intelligence is a multidimensional phenomenon that cannot be reduced to a score. Exploring one&#8217;s cognitive profile \u2014 specific strengths, areas for improvement, characteristics \u2014 is a richer and more useful approach than trying to assign a number to one&#8217;s brain.

Origins and Definition<\/h2>\n\n    <p>The intelligence quotient (IQ) is a standardized measure aimed at assessing an individual's general cognitive abilities compared to those of a reference group of the same age. It was developed in the early 20th century by the French psychologist Alfred Binet, commissioned by the government to identify children needing special educational support. Binet's measure was based on \"mental age\" \u2014 if an 8-year-old child succeeded in tasks typically passed by 10-year-old children, their mental age was considered to be 10 years.<\/p>\n\n    <p>The initial formula for IQ (mental age \/ chronological age \u00d7 100) was replaced in the 1960s by \"deviation IQ\" \u2014 the current score, which no longer compares to a mental age but positions an individual's result relative to the distribution of results of their age group. It is this deviation IQ that all modern tests measure.<\/p>\n\n    <h3>How is IQ set at 100?<\/h3>\n\n    <p>The average IQ is set at 100 by construction \u2014 it is a statistical convention, not a biological reality. During the standardization (or \"normalization\") of an IQ test, the designers administer it to a large representative sample of the population, calculate the median performance of each age group, and assign it the score of 100. The scores of other individuals are then positioned relative to this median according to a normal distribution (bell curve), with a standard deviation of 15 points.<\/p>\n<div class=\"highlight-box\">\n        <h4>\ud83d\udcca The normal distribution of IQ in the population<\/h4>\n        <p>IQ scores follow a normal distribution (bell curve) with an average of 100 and a standard deviation of 15. This means that :<br><br>\n        \u2022 <strong>68 %<\/strong> of the population is between 85 and 115 (\u00b11 standard deviation)<br>\n        \u2022 <strong>95 %<\/strong> of the population is between 70 and 130 (\u00b12 standard deviations)<br>\n        \u2022 <strong>99.7 %<\/strong> of the population is between 55 and 145 (\u00b13 standard deviations)<br>\n        \u2022 Only <strong>2.2 %<\/strong> of the population has an IQ above 130<br>\n        \u2022 Only <strong>2.2 %<\/strong> of the population has an IQ below 70<\/p>\n    <\/div>\n\n    <h2>The distribution of IQ scores: ranges and meanings<\/h2>\n<div class=\"bell-curve-container\">\n        <h4>\ud83d\udcca Distribution of IQ scores in the population<\/h4>\n        <div class=\"iq-range-grid\">\n            <div class=\"iq-range-card\" style=\"background:#fde8ee;\">\n                <span class=\"range\" style=\"color:#e73469;\">&lt;

It is one of the first to decline with age, but also one of the most sensitive to fatigue and acute stress.<\/p>\n    <\/div>\n\n    <h2>The Flynn effect: why does the average IQ increase?<\/h2>\n\n    <p>One of the most fascinating \u2014 and most discussed \u2014 phenomena in psychometrics is what New Zealand researcher James Flynn documented in the 1980s: the average IQ increases by about 3 points per decade since tests have existed. This phenomenon, called the \"Flynn effect,\" is robust and has been observed in many countries.<\/p>\n\n    <p>What explains it? Not genetic change (too slow to produce this effect in a few decades). The most serious hypotheses point to: better nutrition during childhood (especially in micronutrients), reduced exposure to neurological toxins (like lead), longer and more intensive schooling, and \u2014 probably the most important factor \u2014 increasing familiarity with abstract thinking and reasoning modes required by IQ tests.<\/p>\n\n    <div class=\"tip-box\">\n        <h4>\ud83d\udca1 What the Flynn effect teaches us about IQ<\/h4>\n        <p>If the average IQ increases by 3 points per decade, it means that a score of 100 in 2024 does not correspond exactly to the same level of performance as a score of 100 in 1980. Tests are regularly re-normed to keep the average at 100. This also illustrates that performance on IQ tests is influenced by the environment \u2014 schooling, nutrition, cognitive stimulation \u2014 and not just by \"innate\" abilities.<\/p>\n    <\/div>\n\n    <h2>Can IQ increase or decrease?<\/h2>\n\n    <p>This is one of the most frequently asked questions \u2014 and the answer is nuanced. IQ is relatively stable in adulthood under normal conditions. But \"relatively stable\" does not mean \"completely fixed.\" Factors can modify performance on IQ tests:<\/p>\n<div class=\"checklist\">\n        <h4>\u2714 Factors that can affect IQ test results<\/h4>\n        <ul>\n            <li><strong>Education and intellectual stimulation:<\/strong> quality schooling and environments rich in cognitive stimulation improve cognitive performance<\/li>\n            <li><strong>Health status:<\/strong> neurological diseases, nutritional deficiencies, sleep disorders, and chronic stress degrade cognitive performance<\/li>\n            <li><strong>Aging:<\/strong> some components (fluid reasoning, processing speed) decline with age, while others (verbal comprehension) remain stable or even improve<\/li>\n            <li><strong>Specific test training:<\/strong> familiarizing oneself with test formats can improve scores by 5 to 15 points \u2014 without necessarily improving underlying cognitive abilities<\/li>\n            <li><strong>Motivation and emotional state on test day:<\/strong> anxiety, fatigue, or lack of motivation can significantly depress scores<\/li>\n        <\/ul>\n    <\/div>\n\n    <h3>Can cognitive training improve IQ?<\/h3>\n\n    <p>The research on this point is nuanced. Cognitive training programs (notably intensive working memory training) have shown improvements on trained tasks, and sometimes transfers to related tasks. More recent studies have found modest effects on components of fluid reasoning with intensive and prolonged programs. The effect on \"IQ\" in the broad sense remains debated \u2014 but the improvement of specific cognitive functions (memory, attention, executive functions) is well documented.<\/p>\n\n    <p>DYNSEO offers cognitive stimulation applications tailored to each age to support this training: <a href=\"https:\/\/www.dynseo.com\/en\/brain-games-apps\/clint-brain-games-for-adults\/\" target=\"_blank\"><strong>CLINT for adults<\/strong><\/a>, <a href=\"https:\/\/www.dynseo.com\/jeux-de-memoire\/coco-jeux-enfants\/\" target=\"_blank\"><strong>COCO for children aged 5 to 10<\/strong><\/a>, and the <a href=\"https:\/\/www.dynseo.com\/coach-ia\/\" target=\"_blank\"><strong>AI Coach<\/strong><\/a> for personalized support.<\/p>\n\n    <h2>The limits of IQ: what it does not measure<\/h2>\n\n    <p>IQ is a powerful and well-validated psychometric tool for what it measures. But it is crucial to understand its limits to avoid overinterpretation.<\/p>\n\n    <div class=\"method-card rose\">\n        <div class=\"method-badge badge-rose\">\u26a0\ufe0f Limit 1<\/div>\n        <h4>IQ does not measure all forms of intelligence<\/h4>\n        <p>Howard Gardner proposed in 1983 his theory of multiple intelligences \u2014 musical, bodily-kinesthetic, interpersonal, intrapersonal, naturalistic \u2014 which are not or are poorly measured by standard IQ tests. Robert Sternberg introduced the notion of practical intelligence (adaptive know-how in the real world) and creative intelligence. These theories are discussed in cognitive sciences, but they remind us that IQ captures only a part of human abilities.<\/p>\n    <\/div>\n\n    <div class=\"method-card yellow\">\n        <div class=\"method-badge badge-yellow\">\u26a0\ufe0f Limit 2<\/div>\n        <h4>IQ is not destiny<\/h4>\n        <p>An IQ score does not predict individual success or happiness. Factors such as perseverance, curiosity, creativity, emotional intelligence, socioeconomic conditions, the quality of education received, luck, and health play an equally important role in life trajectories. Studies show that \"deliberate practice\" (sustained effort over the long term) often predicts success better than IQ.<\/p>\n    <\/div>\n\n    <div class=\"method-card teal\">\n<div class=\"method-badge badge-green\">\u26a0\ufe0f Limit 3<\/div>\n        <h4>IQ can be affected by cultural biases<\/h4>\n        <p>IQ tests were developed in specific cultural contexts, and some items may favor people familiar with certain cultural, linguistic, or educational codes. Significant efforts have been made to reduce these biases in modern versions of the tests, but they are not completely eliminated. A low score does not necessarily mean limited cognitive abilities.<\/p>\n    <\/div>\n\n    <h2>Average IQ and context: international comparisons<\/h2>\n\n    <p>Studies have attempted to compare average IQs between countries and regions. These comparisons are delicate \u2014 tests are not always equivalent from one cultural context to another, testing conditions vary, and sample selection biases are significant. Available data suggest significant variations between countries, largely correlated with the level of economic development, the quality of educational systems, access to healthcare, and exposure to toxic factors such as lead. What is clear: the differences observed between groups are mostly environmental in nature, not genetic.<\/p>\n\n    <h2>IQ and High Intellectual Potential (HIP)<\/h2>\n\n    <p>An IQ of 130 or higher conventionally defines High Intellectual Potential (HIP) \u2014 which represents about 2 to 2.5% of the population. People with HIP may exhibit specific characteristics that go beyond simple cognitive performance: tree-like thinking, sensory hyperesthesia, emotional hypersensitivity, perfectionism, feelings of social mismatch. HIP is not without challenges: school boredom, difficulty finding peers of similar level, and sometimes associated psychological distress are realities for some of these individuals.<\/p>\n\n    <div class=\"quote-box\">\n        <p>\"A high IQ is like a powerful engine \u2014 it says nothing about the direction one is taking, nor about how one drives.\"<\/p>\n        <div class=\"author\">\u2014 Adapted from research on intelligence and success (Sternberg, 2019)<\/div>\n    <\/div>\n\n    <h2>Beyond IQ: how to assess your cognitive profile?<\/h2>\n\n    <p>Rather than focusing on a single number, the most useful approach is to explore your cognitive profile \u2014 the specific strengths and weaknesses in different cognitive areas. A cognitive profile can reveal excellent working memory associated with average processing speed, or very high verbal comprehension associated with less developed executive functions.<\/p>\n\n    <div class=\"program-card\">\n<div class=\"program-card-content\">\n            <h4>\ud83e\uddea Explore your cognitive profile with DYNSEO<\/h4>\n            <p>DYNSEO offers several online cognitive tests to assess different dimensions of your cognitive abilities \u2014 well beyond a simple overall score:<\/p>\n            <p>\u2022 <a href=\"https:\/\/www.dynseo.com\/test-age-mental-quel-est-lage-de-votre-cerveau\/\" target=\"_blank\"><strong>Mental age test<\/strong><\/a> \u2014 estimate the cognitive age of your brain<br>\n            \u2022 <a href=\"https:\/\/www.dynseo.com\/test-des-fonctions-executives\/\" target=\"_blank\"><strong>Executive functions test<\/strong><\/a> \u2014 planning, flexibility, inhibition<br>\n            \u2022 <a href=\"https:\/\/www.dynseo.com\/test-memoire\/\" target=\"_blank\"><strong>Memory test<\/strong><\/a> \u2014 assess your memory capabilities<br>\n            \u2022 <a href=\"https:\/\/www.dynseo.com\/nos-tests\/\" target=\"_blank\"><strong>All DYNSEO cognitive tests<\/strong><\/a><\/p>\n            <a href=\"https:\/\/www.dynseo.com\/nos-tests\/\" target=\"_blank\" class=\"cta-button\">Discover all tests<\/a>\n        <\/div>\n    <\/div>\n\n    <p>For professionals supporting children or adults in educational, therapeutic, or educational settings, the <a href=\"https:\/\/www.dynseo.com\/nos-outils\/tableau-suivi-competences\/\" target=\"_blank\"><strong>DYNSEO skills tracking table<\/strong><\/a> allows for documenting the evolution of cognitive abilities over time \u2014 a valuable complement to one-time assessments.<\/p>\n\n    <div class=\"faq-item\">\n        <h4>Is an online IQ test reliable?<\/h4>\n        <p>Public online IQ tests are generally not rigorously standardized and cannot replace a professional psychometric evaluation.

From what age?<\/h4>\n        <p>Yes. Validated IQ tests exist for children from the age of 2 and a half (WPPSI for young children, WISC-V from 6 years old). These assessments are conducted by neuropsychologists or specialized psychologists, most often in the context of a school evaluation, suspicion of giftedness, or assessment of learning disorders.<\/p>\n    <\/div>\n\n    <div class=\"faq-item\">\n        <h4>What is the link between IQ and neurodevelopmental disorders such as ADHD or dyslexia?<\/h4>\n        <p>Neurodevelopmental disorders (ADHD, dyslexia, dyscalculia, autism) are not defined by a low IQ. Individuals with ADHD or dyslexia can have a very high IQ. What characterizes these disorders is a disharmony in the cognitive profile \u2014 marked strengths and difficulties in specific areas, often associated with very variable scores between the different sub-tests of an IQ assessment. This is why analyzing the intra-individual profile is often more important than the overall score.<\/p>\n    <\/div>\n\n    <div class=\"conclusion\">\n        <h2>Conclusion: IQ, a tool among others to understand intelligence<\/h2>\n        <p>IQ is a useful and scientifically validated indicator for certain questions \u2014 particularly in clinical settings, special education, and research on cognitive abilities. The average IQ of 100 is a statistical convention that allows situating an individual relative to their age group, but it says little about their value, potential for development, or ability to thrive and succeed in life.<\/p>\n        <p>Intelligence is a multidimensional phenomenon that cannot be reduced to a score.
