How do Howard Gardner's multiple intelligences differ from traditional IQ testing?

Howard Gardner's theory of multiple intelligences fundamentally differs from traditional IQ testing by proposing that intelligence is not a single, measurable entity, but rather a combination of distinct intellectual capacities. Traditional IQ tests, such as the Stanford-Binet Intelligence Scale, aim to provide a single score representing general intelligence, often referred to as an intelligence quotient (IQ).1234

Gardner, however, identified at least eight separate intelligences: linguistic, musical, logical-mathematical, spatial, bodily-kinesthetic, interpersonal, intrapersonal, and naturalistic. He argued that an individual's cognitive profile is better represented by the varying levels of these distinct intelligences rather than a single IQ score. Gardner's theory was inspired by his observations of cognitive processing, brain damage, exceptional individuals, and cross-cultural cognition, challenging the notion that intelligence is ethnocentric and culturally biased. While IQ tests often focus on skills like judgment, comprehension, and reasoning, Gardner's model includes abilities like musical talent and bodily-kinesthetic skills, which are not typically measured by traditional intelligence tests.1253
