How is it possible for psychometricians to develop IQ tests for people smarter than them?

How do psychologists determine IQ?

The IQ score was calculated by dividing the test taker’s mental age by their chronological age, then multiplying this number by 100. For example, a child with a mental age of 12 and a chronological age of 10 would have an IQ of 120: (12÷10) x 100 = 120.

Do IQ tests accurately predict someone’s intelligence?

IQ tests measure a variety of skills like working memory, fluid reasoning, verbal comprehension and more. But he notes the science suggests IQ tests are still not well equipped to provide meaningful scores for these separate abilities, and should be interpreted only as measuring someone’s overall general intelligence.

How are IQ tests developed?

Historically, IQ was a score obtained by dividing a person’s mental age score, obtained by administering an intelligence test, by the person’s chronological age, both expressed in terms of years and months. The resulting fraction (quotient) was multiplied by 100 to obtain the IQ score.

How can intelligence be measured discuss some of good intelligence tests?

If we compare the mental age of a person to the person’s chronological age, the result is the IQ, a measure of intelligence that is adjusted for age. A simple way to calculate IQ is by using the following formula: IQ = mental age ÷ chronological age × 100.

The idea that both convergent and divergent thinking are important for solving problems, and that intelligence helps in the creative process, is not really new.
