Why are most Reinin dichotomies not really useful?
Because very different types belong to the same groups.
Democratic/Aristocratic: Betas are aristocratic, indeed. Deltas not really...
Tactical/Strategic: NJs are strategic, indeed. SPs not really, they fail to plan ahead...
Carefree/Farsighted: ENFp and ENTp are carefree, indeed. ENFj not at all, they worry all the time. They could be called shortsighted instead of carefree...
So why should there be 8 types in one group? It just doesn't work.
Smaller groups with 4 types are appropriate for explaining behaviour and even for typing.
Carefree / Farsighted: (replaced carefree with shortsighted because ENFj and ISFj are not "carefree" at all)
IS = shortsighted doers --- 4-dimensional --- "let's do what makes us happy today"
EN = shortsighted dreamers --- 4-dimensional --- "let's see what happens today"
ES = farsighted doers --- 4-dimensional --- "how can we reach that long-term goal?"
IN = farsighted dreamers --- 4-dimensional --- "what might happen in the future?"
Yielding / Obstinate:
IF: yielding feelers --- 4-dimensional --- "Behave as you wish as long as it doesn't affect me."
ET: yielding thinkers --- 4-dimensional --- "Believe what you like. I will work hard instead of discussing with you."
IT: obstinate thinkers --- 4-dimensional --- "I know the truth. Believe it or prove otherwise!"
EF: obstinate feelers --- 4-dimensional --- "I know how to behave ethically. Do it like that, too!"
Static / Dynamic:
EP: sanguine --- static perceiving function as base --- "A seems to be interesting, B seems to be boring."
IJ: phlegmatic --- static judging function as base --- "A is right, B is wrong."
EJ: choleric --- dynamic judging function as base --- "If we do A we will achieve B"
IP: melancholic --- dynamic perceiving function as base --- "If A happens B will happen"
Democratic / Aristocratic: (replaced with individualist / collectivist)
Alphas: peaceful individualists --- valued . blocked with --- "I am what I am, you are what you are."
Gammas: competitive individualists --- valued . blocked with --- "I am rich, beautiful and intelligent - you are poor, ugly and stupid."
Betas: competitive collectivists --- valued . blocked with --- "We are the master race, you are subhumen."
Deltas: peaceful collectivists --- valued . blocked with --- "We are friends, you are other people"
Si means peace, Se means competition.
Judging personal relationships is Fi-related, seeing the big picture is Ne-related, seeing single aspects is Se-related
For Alphas and Gammas Fi is blocked with Se so they rather see their relationship with every single human. That's why they are individualists.
For Betas and Deltas Fi is blocked with Ne so they rather see the big picture, their relationship with a group. That's why they are collectivists.
