The Measurement of Intelligence
Quick Summary
Lewis Terman's 1916 book, The Measurement of Intelligence, presented his Stanford revision of the Binet-Simon intelligence scale. This work introduced the concept of the intelligence quotient, or IQ, which compares a person's mental age to their chronological age, with an average score of 100. Terman's research also included a long-term study of gifted children, a term he coined, which challenged stereotypes by finding that gifted individuals tended to be healthier and more stable than average. His work supported the development of mass intelligence testing, including programs for the U.S. Army.12
