Complementary relation

Semi-duality

ESI ↔ LSE

There may be real warmth and understanding here, along with a gap that keeps showing up when they try to coordinate.

Also called Partial duality

ESI and LSE stand in the same position, so the relation reads the same from either side.

How Semi-duality works

When it helps

They speak openly, take each other's concerns seriously, and allow some space without treating it as a setback.

What to notice

Plans can bring unexpected disappointment when they reach an area where neither can give the other enough support.

Complementary relations. One person's strengths may help with things the other finds harder. That can feel supportive, even when they help each other in different ways.

What passes between them

Every type has eight functions, from what comes most naturally to what costs the most effort. These are the places where ESI’s and LSE’s meet most directly.

  • HelpESI → LSETrust and personal bonds Fi

    Comes easily to ESI, and it is exactly the kind of help LSE looks for.

Rows follow Model A’s eight function positions, from Leading (1) to Demonstrative (8); they are not a ranking of strength or value. The highlighted rows are the contacts that hold across all sixteen ordered pairs the archive assigns to Semi-duality.

Where this comes from

The relation name and roles come straight from the archived relation table, and the meeting points follow from Model A. The summaries are the Atlas’s plain-language reading of the archived Semi-duality guide: a place to start, not a prediction about two real people.

Why Semi-duality
The same broad block shape also appears in Benefit and Mirage. The exact order of the contacts is what makes this Semi-duality.
Model A
Function positions and blocks come from the archived Model A and Functions pages (17f5a976a93f…). These contacts hold for all sixteen ordered pairs the table calls Semi-duality, checked against all 256 cells.
