Binet designed a set of tasks — vocabulary, logical puzzles, memory tests, pattern completions — intended as a diagnostic instrument for a specific educational context. He warned explicitly against treating the derived score as a fixed measure of general cognitive capacity. The warning went unheeded. Within two decades, the IQ test had migrated to American immigration stations, military recruitment offices, and corporate hiring departments, becoming, in popular understanding, a definition: intelligence was what IQ tests measured. In Gardner's framework, the test measures linguistic and logical-mathematical intelligence while rendering invisible the six other capacities human cognition comprises.
