IQ and Vocabulary
IQ tests have a long and controversial history, but they remain one of the most popular psychological tests taken today. They measure both crystallized and fluid intelligence. Crystallized intelligence refers to the skills and knowledge you learn throughout your life. It is directly impacted by learning and can increase as you get older. Fluid intelligence refers to your ability to reason, problem-solve, and interpret abstract information. Fluid intelligence is not impacted by learning, and experts believe that it declines as you get older. (1)
Early intelligence quotient tests were scored by dividing a person’s mental age by their chronological age and then multiplying that number by 100. Today, IQ scores are determined by how far someone differs from the average score, which is 100. (1, 2)
This means that the mean IQ score is 100, with about two-thirds of all scores falling within 15 points above or below it. So if you have a score around 100, you’re of average intelligence, as do the vast majority of people who take an IQ test. (1, 2)
Many IQ tests include subtests that measure things like memory, reasoning skills, processing speed, mathematical skills, and language skills. This is one reason some people believe that vocabulary and intelligence quotient are related and that you can increase your IQ by improving your vocabulary. (1)
