This Indicator has been developed over thirty-five years of rigorous scientific validation and is the most widely used of any Personality Indicator . The Indicator is a very useful tool to enlarge and deepen our self-knowledge and understanding of our behaviour. It can be of real benefit to us in making informed life-choices and in relationship building. It is not a test . There are no right or wrong answers .
TYPE is a shorthand way of describing four sets of mental processes.
Types are not pigeonholes, but describe preferred ways of functioning in the world. Just as every person has a differently shaped body, so each of us has a differently 'shaped' personality. There are sixteen different combinations of letters corresponding to sixteen different and unique Personality Types. Each scale represents two ends of a continuum of two preferences. These are like 'right' or 'left-handedness' to use an example.
