In his career books (Pathfinder and Now What?) Nicholas Lore uses the mbti plus the maestro or tribal preference to form your core type.
Maestros (around 25% of the population) are essentially misfits and sometimes outsiders; oddballs on their own wavelength who are often specialists of some sort.
Tribals are group workers and team players, preferring to work in an organization and contribute to its goals. It follows that tribals are the majority in such places as the corporate world and government agencies.
The degree of your tribal or maestro preference can, of course, range from mild to extreme. Here are some identifying characteristics of each from Lore’s checklist:
Tribal – On same wavelength as others; prefer to be part of a team; consider yourself to be like other people; are attracted to team sports or activities; fit in naturally; sometimes wish you stood out more; prefer to collaborate on ideas with others; into popular TV shows; know just enough in your areas of interest; have similar taste in music as peers; keep in touch with family a lot; can take and give orders easily
Maestro – On your own wavelength; prefer to do your own thing; read in depth on subjects of interest; are unique, different from others; have unusual taste in TV shows; dress distinctively; family has to remind you to keep in touch; don’t like being told what to do; challenge the typical way of doing things; not a joiner; prefer your own individual ideas; dream of living a different and highly personalized lifestyle; sometimes wish you were a bit more normal
Another comparison that comes to mind is that tribals are more like dogs and maestros are like cats.
Career examples from Lore’s book:
Extroverted tribal: sales people, networkers, administrators, personnel directors, flight attendants, lobbyists, fund-raisers
Introverted tribal: generally favor more secluded positions within the hive such as clerical workers, accountants, financial analysts, etc.
Extroverted maestro: performing artists, college professors who enjoy the classroom audience, comedians, dancers, actors
Introverted maestro: artists, novelists, specialists, inventors, actors, professors who prefer research and writing to the classroom
