IQ, or Intelligence Quotient, is a standardized score that measures an individual’s mental ability in relation to their peers. The average IQ score is 100, which is determined by administering the same test to a large and diverse group of people.
The concept of IQ was introduced in 1912 by psychologist William Stern. Initially, IQ was calculated as the ratio of an individual’s mental age to their chronological age, multiplied by 100. For example, if a 10-year-old had a mental age of 10, their IQ would be 100. If their mental age was higher (e.g., 12), their IQ would be greater than 100. Conversely, if their mental age was lower, their IQ would be below 100.
These days, people measure their IQ to gain insights into their level of intelligence. While an IQ score doesn’t define whether someone is “smart” or “not smart,” it does provide valuable information about cognitive abilities.
IQ scores offer a means to assess how knowledgeable someone is compared to others in their age group. It’s a scale that provides useful information about intellectual capabilities.
