How is intelligence measured?

Intelligence is typically measured using standardized tests, such as IQ (intelligence quotient) tests. These tests assess various cognitive abilities, including verbal comprehension, perceptual reasoning, working memory, and processing speed. The most commonly used IQ test is the Wechsler Adult Intelligence Scale (WAIS) for adults and the Wechsler Intelligence Scale for Children (WISC) for children. These tests provide a numerical score that represents an individual's intelligence level compared to others in their age group. However, it is important to note that intelligence is a complex and multifaceted concept, and these tests may not capture all aspects of intelligence.
