Personality Key

All Personality Systems

Eight independent lenses for personality and relationship reflection. Each asks its own questions, uses its own scoring, and produces its own results.

Why multiple systems?

No single model asks every useful question. These lenses cover broad traits, motivation, cognitive preferences, relationship patterns, and playful archetypes. Each remains partial and stands on its own.

Independent measurement

Each system runs end-to-end on its own terms. No shared questions, no borrowed scoring, no collapsed dimensions. This means more questions overall, but each result is genuinely what that system claims to measure.

Transparent science

Every item has documented provenance and provisional psychometric fields. Every measured result shows its uncertainty. All eight packs are currently marked as "piloted" — their parameters and norms are illustrative, not validated.

The Five Domains

The science-backed one

How you score across five broad traits — openness, conscientiousness, extraversion, agreeableness, and neuroticism. The most studied model in personality research, shown as a profile rather than a single type.

Tradition five-factor-model
Epistemics typology
Format Adaptive
Scoring

What it measures

A five-domain model of personality with the strongest empirical support of any framework here. This particular instrument, however, is a new one and has not yet been validated on real responses.

Four Preferences

The four-letter one

Four either/or preferences — like preferring quiet nights over big parties — combine into a four-letter type like ENFP. This version also shows how clear-cut each preference was, not just the letter.

Tradition jungian-type
Epistemics typology
Format 40 items
Scoring dichotomize

What it measures

Four forced-choice preferences, reported as letters with explicit margin bands. The best-known weakness of this tradition is that a narrow split and a wide one produce the same letter; this instrument reports the margin so you can see which you got.

The Nine Types

The one about motivation

Which of nine core motivations drives you — the reformer, the helper, the achiever, and so on. Instead of how you act, it asks why you act, which is why it can't be read off the Big Five.

Tradition enneagram
Epistemics typology
Format 45 items
Scoring rankedEndorsement

What it measures

A motive-based typology with a long practitioner tradition and limited empirical validation. It asks what drives you rather than how you behave, which is why it needs its own instrument rather than being read off a trait profile.

Signs and Affinities

The one for reflection

The sign you were born under, and the sign your own answers lean toward — run side by side. Not a measurement and not a claim that the stars cause anything: the gap between the two is what's worth a look.

Tradition western-astrology
Epistemics symbolic
Format 35 items
Scoring

What it measures

A symbolic vocabulary, run two ways at once: the sign you were born under, and the sign your own answers lean toward. Neither is a measurement, and nothing here claims the sky caused anything. The gap between the two is the part worth looking at.

Eight Function-Attitudes

The Jungian functions, continuous

Eight cognitive function-attitudes — Se, Si, Ne, Ni, Te, Ti, Fe, Fi — scored as continuous dimensions. No type reduction, just the raw profile of how you engage with the world.

Tradition jungian-function
Epistemics typology
Format 40 items
Scoring irtTheta

What it measures

Jung's eight function-attitudes (Se, Si, Ne, Ni, Te, Ti, Fe, Fi) scored as continuous traits, never collapsed to a single dominant. This is the move the Singer-Loomis literature argued for and the MBTI's own evidence base concedes: the functions are dimensions, not types, and cutting them loses the most information exactly where it is densest.

Dominant Function

Your leading cognitive function

Which of Jung's eight function-attitudes dominates your psyche? This system ranks them by separation and reports a dominant only when the data clearly supports one — no forced types.

Tradition jungian-function
Epistemics typology
Format 40 items
Scoring rankedEndorsement

What it measures

Jung's eight function-attitudes scored as a ranked vector, with a dominant function reported only when the top two separate clearly. This is the move the Singer-Loomis design argues for — continuous scoring, a dominant selected by separation rather than by a forced dichotomy — applied to the question 'which function do you lead with?'

Care Preferences

How care tends to reach you

Five ways care may feel meaningful, shown as a mixed profile rather than one permanent primary preference.

Tradition relationship-reflection
Epistemics typology
Format 25 items
Scoring irtTheta

What it measures

Five original, continuous scales describing ways care may feel meaningful. The profile does not select one permanent primary preference, rank a partner, or predict compatibility.

Attachment Patterns

Closeness and reassurance, in two dimensions

A continuous look at concern about reassurance and caution around closeness, without a fixed style label.

Tradition adult-attachment
Epistemics typology
Format 16 items
Scoring irtTheta

What it measures

Two continuous adult attachment-related tendencies: concern about reassurance and caution around closeness. No four-style label, diagnosis, or judgment of a relationship is issued.
