Howard Gardner's theory of multiple intelligences (MI), introduced in Frames of Mind (1983), proposes that human intelligence is not a unitary capacity measured by IQ tests but a set of relatively autonomous intelligences. Gardner originally identified seven intelligences — linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, interpersonal, and intrapersonal — and later added naturalistic intelligence. Each intelligence has its own developmental trajectory, neural substrate, and set of expert end-states, and can function independently of the others.

The Eight Intelligences
Linguistic intelligence involves sensitivity to language and words (writers, lawyers). Logical-mathematical intelligence involves numerical reasoning and scientific thinking (mathematicians, scientists). Spatial intelligence involves mental manipulation of spatial configurations (architects, pilots). Musical intelligence involves sensitivity to rhythm, pitch, and melody (composers, performers). Bodily-kinesthetic intelligence involves skilled control of one's body (athletes, dancers). Interpersonal intelligence involves understanding others' emotions and motivations (therapists, leaders). Intrapersonal intelligence involves self-knowledge and self-regulation. Naturalistic intelligence involves recognizing and classifying natural objects (biologists, farmers).
Criteria for an Intelligence
Gardner established eight criteria for identifying an intelligence: potential isolation by brain damage, the existence of savants and prodigies, an identifiable core operation, a distinctive developmental history, evolutionary plausibility, support from experimental psychology, support from psychometric findings, and susceptibility to encoding in a symbol system. Each proposed intelligence was evaluated against these criteria before inclusion — a more theoretically grounded approach than simply identifying factors in test batteries.
MI theory has been enormously influential in education but controversial in psychology. Critics argue that Gardner's intelligences are better described as talents or aptitudes rather than intelligences, that the eight criteria are subjectively applied, that factor-analytic evidence consistently supports g rather than independent intelligences, and that there is no empirical evidence that teaching to different intelligences improves learning outcomes. The theory's educational applications (learning styles matched to intelligences) have not been supported by controlled research, though the broader message — that human abilities are diverse and schools should cultivate multiple competencies — remains valuable.
Educational Impact
Despite scientific criticism, MI theory has had profound educational impact. It encouraged schools to value diverse abilities beyond linguistic and logical-mathematical skills, to offer varied learning activities, and to recognize that students may excel in different domains. Gardner himself has cautioned against simplistic applications (such as "learning styles" based on MI) and has emphasized that the theory should encourage deep engagement with important topics through multiple entry points rather than superficial matching of instruction to supposed intelligence types.
Disorders
- Specific learning disabilities (disruption of one intelligence)
- Savant syndrome (extreme specific intelligence) — Extraordinary ability in a specific domain (music, art, calculation, memory) alongside general intellectual disability or autism.
