The fourteen relation types

Same-quadra relations

Both of the partner's ego functions are among the values I hold. The partner is from the same quadra.

Identity
Instant understanding without explanation, and shared blind spots nobody points out.
Duality
The closest relation possible: each side covers exactly what the other cannot, without conscious effort.
Activation
Mutual energy that ignites fast, and exhausts if it runs too long without a break.
Mirror
The same values in reverse order: high intellectual understanding and a quiet rivalry over method.

Symmetric adjacent-quadra relations

One of the partner's functions is among my values and the other is not. The partner is from a quadra that shares half my values, and the relationship is lived the same way from both sides.

Asymmetric (ring) relations

The same mix of a valued and an unvalued function, and the partner is also from an adjacent quadra. The difference is that the relationship has a direction, so each side experiences it differently, and it runs in rings of four types.

Opposite-quadra relations

Both of the partner's ego functions lie outside my values. The partner is from the opposite quadra (Alpha with Gamma, Beta with Delta).
