How many intelligences has Howard Gardner identified?

Howard Gardner, a developmental psychologist, introduced the theory of multiple intelligences in 1983. He identified a range of distinct forms of intelligence that reflect different ways of processing information and learning. In total, Gardner's research has led to the identification of nine intelligences. These include linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, naturalistic, and existential intelligence. Each of these intelligences showcases a unique way that individuals can learn and interact with the world around them, emphasizing the diversity of human capabilities beyond traditional academic skills.
