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.

People frequently discuss extremely high IQ scores, also known as genius IQ scores, but what do these figures actually mean and how do they compare? Are people with higher IQs more successful than those with lower IQs? According to some professionals, emotional intelligence may even be more important than IQ. The term "intellectual quotient," or IQ, refers to a person's capacity for reasoning. In other words, it's meant to determine how well a person can use knowledge and reasoning to provide answers or form predictions. IQ tests measure short- and long-term memory to start evaluating this. They also gauge how quickly and accurately people can recall information from lectures and solve puzzles.

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.

Some children were able to respond to the questions typically answered by children of an older age, so these children had a higher mental age than their actual chronological age.

IQ classification is the practice of categorizing human intelligence, as measured by intelligence quotient IQ tests, into categories such as "superior" or "average". In the current IQ scoring method, an IQ score of means that the test-taker's performance on the test is of average performance in the sample of test-takers of about the same age as was used to norm the test. An IQ score of means performance one standard deviation above the mean, while a score of 85 means performance one standard deviation below the mean, and so on. By the current "deviation IQ" definition of IQ test standard scores, about two-thirds of all test-takers obtain scores from 85 to , and about 5 percent of the population scores above i. When IQ testing was first created, Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number regardless of testing procedure. Variability in scores can occur when the same individual takes the same test more than once. Even before IQ tests were invented, there were attempts to classify people into intelligence categories by observing their behavior in daily life.

Kendra Cherry, MS, is a psychosocial rehabilitation specialist, psychology educator, and author of the "Everything Psychology Book. 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. The average score on an IQ test is These labels are often given for IQ scores:. An average IQ score is between 85 and

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. In a new book, Intelligence: All that Matters , Ritchie persuasively argues that IQ doesn't necessarily set the limit for what we can do, but it does give us a starting point. And the truth is some people start ahead. Most of these charts have been pulled from Intelligence: All that Matters.
