From Keirsey to OnType

An ancient idea, a modern theory

The idea of four temperaments reaches back to ancient Greek thought, including Plato. Psychologist David Keirsey developed it into a modern theory in Please Understand Me (with Marilyn Bates, 1978), linking four temperaments to the sixteen types. Each temperament shares characteristic interests, values and ways of contributing.

OnType keeps Keirsey's four groups, calling his Rationals the Intellectuals, and builds on later work in the Jungian community led by C.S. Joseph. Each temperament is made of three pairs of traits: concrete or abstract, affiliative or pragmatic, and interest or systematic.

Concrete types, whose sensing functions sit high in their stack, focus on what is and what was: the tangible and the useful. Abstract types focus on what could be: hypotheticals, possibilities and hidden patterns.
