12 dichotomies, Dual type, ratian socionics 2.0
There are 24 numerology problems described by hilbert which can be translated into basic functions. You can find the problems 'hilbert problems' on wiki. I've taken problems 1-12 & their functions & attached personality attributes to them, and gotten the following:
1: subjective / objective - internal / external
2: static / dynamic
3: field / object
the words from here on need some refinement, but the idea is there
4: affirming / negating
5: creative / reductive - DHCN
6: abstract / concrete - DHCN - If you are reductive & abstract, you are H in DHCN. creative & abstract - N; creative & concrete - C; reductive & concrete - D.
Dual Type:
7: expressive / receptive -
8: optimistic / pessimistic -
9: assertive / inquisitive -
10: initiating / responding -
11: idealistic / empirical - DHCN for dual type
12: absolutist / relativist - DHCN for dual type. idealistic relativist H; empirical relativist - N; empirical absolutist - C; idealistic absolutist - D
All 12 of these together form a full type. The full type looks like:
RAT: INFp-Ni-H;ESTp-Se-D
