Nobody wants to be a number. But there is one number that probably says a lot about you, whether you know it or not: your IQ, or intelligence quotient. IQ is often dismissed as antiquated, misguided, or less important than personality traits. But according to Stuart Ritchie , an intelligence researcher at the University of Edinburgh, there's a massive amount of data showing that it's one of the best predictors of someone's longevity, health, and prosperity. And psychologists have been able to replicate these findings over and over.

Herrnstein and libertarian political scientist Charles Murray. Its central argument is that human intelligence, measured by IQ tests, is influenced substantially by both inherited and environmental factors, and IQ is better predictor of financial income, job performance, and involvement in crime than are parental socioeconomic status or education level. This claim is supported by the facts. It is called a bell curve because of its bell shape. It has a similar shape for all populations in which IQ has been measured. Now look at this data on college students, based on SAT scores. First, going back to translating back from standard deviations to IQ scores! The average IQ of Ivy League colleges was But if we jump forward to , just before The Bell Curve was written, you see a very different picture. While the average IQ of all college graduates in the country has barely changed from to , the average IQ of Ivy League college graduates has increased from to That was back in Now the IQ level may be even greater, assuming it has not reached close to its natural limit — as we find in elite athletes. The Bell Curve was controversial, and generated a lot of inaccurate and misleading public reports and discussion about IQ. To counter these reports an IQ manifesto was issued in the Wall Street Journal in December , signed by 52 professors specializing in intelligence and related fields, including around one third of the editorial board of the journal Intelligence. We have come on since then in our understanding of IQ considerably but these points are still accepted and provide a good starting point for our current understanding.

However, some students have difficulty in the classroom due to a deficiency in a particular area of intelligence.

The distribution of the scores on these tests fall uniformly from each side of the mean and form what is known as the IQ bell curve. This distribution of scores is known as a standard distribution, seen in the graph below of the score distribution for the Wechsler intelligence tests. The IQ bell curve helps categorize where people fall along the scale of intelligence and does so in a neatly compartmentalized way. If you look at the graph above, you can see that there are equal parts above and below the mean of The further out you go you will find fewer and fewer people, as only 4. The next level of scores above or below these levels is extremely rare, as people with IQs below 55 are intellectually impaired, while people with IQs above are exceptionally gifted and often considered geniuses.

The IQ percentile calculator lets you find out what percentage of people score lower than you in the IQ test scales. IQ, a measure of fluid intelligence, is known to be the best predictor of academic and occupational success, especially in cognitively demanding disciplines, which is why finding your IQ can help you when making decisions about your career. Psychologists divide human intelligence into crystallized and fluid intelligence. Crystallized intelligence refers to acquired knowledge and skills. Fluid intelligence means a general cognitive ability, ability to learn new things, reason, recognize patterns, and draw inferences. IQ is a score obtained from tests invented to measure fluid intelligence. IQ stands for Intelligence Quotient. It's called this way because it used to equal the mental age based on the test score divided by chronological age and multiplied by Nowadays, it is no longer a quotient, although the name remains. The so-called deviation IQ used by most tests is determined by comparing scores to the average performance of the representative group in the person's age range.

People often talk about very high intelligence quotient IQ scores, often referred to as genius IQ scores, but what exactly do these numbers mean and how do they stack up? How do IQ scales break down scores into different IQ levels? Are geniuses more successful than their lower-IQ counterparts? Some experts suggest that other factors, including emotional intelligence , might matter even more than IQ levels.

Levine, Albert J. Those environments we create can then "amplify" the potential of our genes. Main article: Cognitive Assessment System. Human Intelligence. If you look at the graph above, you can see that there are equal parts above and below the mean of Categorisation of people's intelligence based on IQ. Understanding Our Gifted. Who has the highest IQ ever? Archived from the original PowerPoint on 9 October For instance, Richard Nisbett, a psychology professor at the University of Michigan, stated :.

IQ stands for intelligence quotient and describes a score earned on a test designed to measure intelligence.

Additionally, IQ scores are not fixed and can change over time as a result of environmental and other factors. For rough comparability of scores between the second and third revision of the Stanford—Binet test, scoring table author Samuel Pinneau set for the median standard score level and 16 standard score points for each standard deviation above or below that level. Lewis Terman chose " 'near' genius or genius" as the classification label for the highest classification on his version of the Stanford—Binet test. Because all IQ tests have error of measurement in the test-taker's IQ score, a test-giver should always inform the test-taker of the confidence interval around the score obtained on a given occasion of taking each test. Molecular Psychiatry That is, twins' genes seem to be less important for IQ when they're children compared with when they're adults. It is of course obvious that much error may creep into an experiment of this sort, and the I. The Flynn effect: a meta-analysis. Binet's measure of intelligence was based on the average abilities of children of a particular age group. It is believed that fluid intelligence involves many of the same brain regions. Charles Spearman, bearing in mind the influential theory that he originated—that intelligence comprises both a "general factor" and "special factors" more specific to particular mental tasks—wrote in , "Every normal man, woman, and child is, then, a genius at something, as well as an idiot at something. Teachers can identify which students would benefit from this extra help by using IQ tests. An overview of some valid online IQ tests can be found here.
