John Leonard Horn (September 7, 1928 – August 18, 2006) was a scholar, cognitive psychologist and a pioneer in developing theories of multiple intelligence.
Horn, together with Raymond Cattell, developed the theory of crystallized and fluid intelligence. This theory was later combined with the work of John Carroll and called the Cattell–Horn–Carroll theory. The CHC theory is the basis for many modern IQ tests.[1] Horn's parallel analysis, a method for determining the number of factors to keep in an exploratory factor analysis, is also named after him.
