Model A Dichotomies

Three layers need to be kept distinct: information dichotomies split information itself, functional dichotomies split Model A positions, and type dichotomies divide whole sociotypes.

Watch

Information, Function, Type

Information dichotomies describe the structure of information itself: perception or judgement, external or internal, detached or involved, and the further splits that distinguish the eight information aspects.

Functional dichotomies describe what happens when an information aspect is placed into a Model A position: public or private, strong or weak, valued or neglected, and so on.

Type dichotomies divide the sixteen whole sociotypes into symmetrical groups of eight. Those are treated on The Types page, because they describe complete types rather than aspects or positions.

Information Styles

Four Ways The Elements Move

Once the four domains have been divided into eight elements, two stylistic dichotomies describe how those elements move: Introverted vs Extraverted and Static vs Dynamic. Their intersection produces four information styles. These are not types or functions; they are movement-patterns of information itself.

Erratic: collage of a pinball's flight across a table, a hand flicking through postcards of possible holidays, a ball striking a bat

Erratic

Extraverted + Static

Elements: Ne, Se

Erratic information moves outward through discrete states. It notices objects, openings, impacts, and options as separate points of initiative. Ne and Se share this style: both expand toward what could be started, taken, tried, or made possible.

Fixed: collage of a cartographer inking a firm boundary line, a stone milestone, a sealed jar of preserves on a labelled shelf

Fixed

Introverted + Static

Elements: Ti, Fi

Fixed information turns inward toward stable distinctions. It clarifies boundaries, categories, loyalties, and principles as settled reference points. Ti and Fi share this style: both reduce information toward an internal standard.

Tranquil: collage of a rowing boat drifting on a still lake at dusk, a woman humming as she stirs a slow pot, the turn of a mill wheel

Tranquil

Introverted + Dynamic

Elements: Ni, Si

Tranquil information turns inward through continuous flow. It follows inner processes, rhythms, narratives, atmospheres, and states of ease or inevitability. Ni and Si share this style: both integrate experience as a moving continuity.

Relentless: collage of a steam train under full power, a printing press running off sheets, a drummer leading a marching band

Relentless

Extraverted + Dynamic

Elements: Te, Fe

Relentless information moves outward through process. It tracks activity, expression, production, momentum, and changing external conditions. Te and Fe share this style: both expand by generating and regulating ongoing movement.

Information Attitudes

Four Ways Information Settles

The final two information dichotomies describe whether information tends toward closure or remains open, and whether it gathers toward integration or separates into sharper distinctions. Crossing Conclusive vs Questionable with Attractive vs Repulsive produces four information attitudes.

Appreciating: collage of a man in a meadow gathering wildflowers into a loose bunch, a curiosity cabinet with its doors open, a welcoming armchair

Appreciating

Questionable + Attractive

Elements: Ne, Si

Appreciating information remains open while drawing things into relation. It notices, gathers, welcomes, and keeps possibilities alive. Ne and Si share this attitude: both preserve openness while moving toward integration.

Resolving: collage of a choir closing on one final chord, a jigsaw's last piece pressed in, a family seated together at a table

Resolving

Conclusive + Attractive

Elements: Ti, Fe

Resolving information reaches closure by drawing things together. It settles meaning into a coherent pattern, principle, atmosphere, or shared conclusion. Ti and Fe share this attitude: both make integration definite.

Differentiating: collage of a woman sorting buttons into compartments, a tailor trying a sleeve and pinning it again, a sieve separating flour

Differentiating

Questionable + Repulsive

Elements: Te, Fi

Differentiating information remains open by separating and testing distinctions. It asks what works, what belongs, what does not belong, and what must be revised. Te and Fi share this attitude: both keep refining by discrimination.

Repudiating: collage of a sea wall turning back a storm wave, a hand raised to stop, a gate barred shut, a ship's bow cutting through ice

Repudiating

Conclusive + Repulsive

Elements: Se, Ni

Repudiating information reaches closure by separating, refusing, or cutting away. It identifies what must be resisted, excluded, overcome, or recognised as inevitable. Se and Ni share this attitude: both make separation definite.

Type Dichotomies

Whole-Type Splits

Type dichotomies operate one level higher. They divide the sixteen complete sociotypes into balanced groups of eight. The first four are the Jungian foundation dichotomies; the remaining eleven are the Reinin dichotomies derived from the sixteen-type matrix.
