But in what context?
When profiled you could get four letters. Or one of the big five. Or some number winged with some other number. Or whatever the classification to fit into is.
This puzzles me: But in what context? For every way of being that a classification prescribes: Can you find a context in which that does not fit?
The person that thrives on chaos but switches to a highly structured schedule when on holiday.
The attention-oriented person at work that switches that off at home.
The intense go-getter that flows freely when dancing.
The numbers and letters may have some use. But it does not apply to all contexts, and does not apply to all of one human.
