The 16 types
The 16 types
Sixteen types, sixteen orders of the same eight functions. Each chapter gathers everything about one type: its profile and picture, its eight seats, its four sides, its journey and its idea of success.
The types below are grouped by core need, the temperament David Keirsey described and the DTI test uses. Each one shows its first two functions, the Hero and the Parent, and its rough share of people in the general population.
Shares from US samples of the MBTI Manual: they vary by country and by study, and none is "better" or "rarer" in any way that matters for a life.
