The Kiersey Temperament and Meyers & Briggs Type test are based on Jungian psychology. They both use the same 16 basic personality designations. Each offers a slightly different interpretation of the personality type so both tests are worth doing and reading up on.

In the Meyers and Briggs Personality system “NF”s are Idealists.
David Kiersey, creator of the Kiersey Temperament Sorter says:
“Idealists talk little of what they ovserve ‘of shoes and ships and sealing wax, of cabbages and kings.’ They talk instead of what can only be seen with the mind’s eye: love, tragedy, heart and soul, tales and legends, eras and epochs, beliefs, fantasies, possibilities, symbols, selves and yes, temperament, character and personality.”
