SLI ↔ ILE MODEL A
Semi-duality

Half of duality — reliably the wrong half. The leading functions cover each other exactly as in duality; the support functions don't. Strong starts, weak rescues.

▸ New to socionics? The 90-second primer

Socionics builds types from eight information elements (Ne, Si, Ti, Fe…) placed into eight fixed slots — the slot decides how the element behaves in you.

The three-letter code (SLI) names the top two slots. It looks like an MBTI type; it doesn't convert cleanly — which is the kind of disagreement this site exists to measure.

Want the fuller version? The basics page covers elements, functions, quadras, and the two models.

slots, in one line: base & creative = native strengths · role = performed on demand · vulnerable = the sore spot · suggestive & mobilizing = what's wanted from others · ignoring & demonstrative = strong but not valued. Full definitions on each type page.

§2 IN PRACTICE

Where it clicks

  1. First meetings run themselves — the lead axis is fully covered.
  2. Interest is real: each has a main strength the other genuinely wants.
  3. Recovery after distance is quick; the opening chemistry re-arms.

Where it grinds

  1. Support fails precisely under load — the helper reaches for a tool the other doesn't want.
  2. Near-miss quality: close enough to retry, wrong enough to fail, repeatedly.
  3. Intimacy plateaus below what the opening promised.
§3 DO THE SCHOOLS AGREE HERE?

MODEL A Intertype relations are classical canon — this page is Model A ground. MODEL G keeps the frame but weights temperament and communication energy differently; where that changes a reading, we say so. Nothing here is invented to manufacture a disagreement. method →
