So, an interesting idea arose in the
Romantic Mirage thread, which I have been mulling over for a while.
The idea is that, because types in adjacent quadras share only half of their valued information elements (either the Rational elements or the Irrational elements), Rational and Irrational types will have significant differences in the way they experience adjacent-quadra relationships. That would include Semi-Duality, Kindred, Mirage, Look-a-Like, Supervision, and Benefit.
Essentially, the trend seems to be that partners who share valued Irrational elements will tend to find the relationship comfortable, relaxing, and easy to work together, but ultimately unfulfilling, while parters who share valued Rational elements will find the relationship meaningful, fulfilling, with a deeper personal connection, but ultimately uncomfortable and difficult to work together productively.
Shared Irrational: comfortable, "safe", sympathetic, harmless, casual, easy to work together to achieve a goal, productive, useful, superficial, shallow, unsupportive, unable to support each other during times of stress, unfulfilling, unexciting, void, lacking intimacy and depth
Shared Rational: close and satisfying, fulfilling, meaningful, deep, intimate, easy to discuss points of view but difficult to agree on practical implementation, difficult to execute joint activities, not living up to full potential, can't get anything open-ended done, uncomfortable, under-stimulated, growing laziness
I will call the "shared Irrational" relationship style "Productive-Shallow", and the "shared Rational" style "Unproductive-Deep".
Productive-Shallow Relationships
Rational Types: Mirage, Look-a-Like, Supervisee, Beneficiary
Irrational Types: Semi-Dual, Kindred, Supervisor, Benefactor
Unproductive-Deep Relationships
Rational Types: Semi-Dual, Kindred, Supervisor, Benefactor
Irrational Types: Mirage, Look-a-Like, Supervisee, Beneficiary
In general, it seems that Productive-Shallow relationships connect in terms of lifestyle, but can't make any deeper, personal connections. Unproductive-Deep relations seem to make those deeper personal connections, but clash in terms of how to go about daily life.
Anyway, that's the theory I've been working on. Any input, theoretical insights, personal observations, is welcome!
