The document discusses Howard Gardner's theory of multiple intelligences, which posits that intelligence is comprised of different specific abilities rather than a single general ability. It describes eight types of intelligence: linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalist. People with different intelligences may be drawn to different careers. The document also notes that both heredity and environment contribute to shaping a person's intelligence through the genes inherited from parents and life experiences.
