How Typaria works

How Typaria works

You answer 40 statements one at a time. According to the Myers-Briggs framework, personality preferences are often described with four letter pairs — Extraversion / Introversion, Sensing / Intuition, Thinking / Feeling, and Judging / Perceiving. Typaria uses that vocabulary for the four-letter type, plus an Assured / Tidal identity axis of our own. Independent psychometric research treats personality as largely continuous traits and has long questioned cutting those traits into dichotomous type labels.^{(The Myers & Briggs Foundation, 2024)(McCrae, 1989)(Pittenger, 2005)}

You get an instant type code, percentages showing lean on each axis, a compass shape, and optional share / compare tools. Guides and pairing pages are Typaria editorial writing in that shared vocabulary — not clinical reports.

How scoring works

Every answer is a 1–5 value. Each dimension runs from its first letter at 1.0 to its second letter at 5.0 — E→I, S→N, T→F, J→P, A→T. A plain item is worded toward the first letter, so agreeing with it moves the score down: it becomes 6 − value. A reverse-keyed item is already worded toward the second letter and passes through as-is. The dimension is then the mean of its 8 items, rescaled to a percentage:

item   = reverse ? value : 6 − value   → 1 … 5
mean   = Σ(item values) / 8           → 1.0 … 5.0
lean   = round(((mean − 1) / 4) × 100) → 0 … 100  (toward the second letter)
letter = lean > 50 ? second : lean < 50 ? first : second

An exact 50 is a genuine tie: the items found no preference. A four-letter code cannot print “neither”, so a tie resolves to the second letter — deliberately, and the same way everywhere, so a tied result still survives being shared as a link. Any axis within a couple of points of 50 is labelled balanced on your result rather than reported as a firm preference.

So 50% is the exact midpoint of the scale, not a population average. Typaria does not norm your score against other test-takers — a 62% Intuitive means your answers leaned 62% of the way toward the Intuitive pole, not that you are more intuitive than 62% of people.

Why the questionnaire uses this design

8 items per dimension, 20 of the 40 reverse-keyed. Typaria balances forward- and reverse-keyed items as an attempt to reduce simple agreement-pattern responding. Reverse-keyed items are commonly used for this purpose, but psychometric research is mixed: they can also introduce wording effects, confusion, or additional measurement error. Typaria has not independently validated whether this design improves reliability in our instrument.^{(García-Fernández, 2022)(van Sonderen, 2013)(Elek, 2025)}

Eight items per dimension is a product-design choice: it gives a percentage that is less sensitive to a single misread question than a four-item scale would be. Item count alone does not establish reliability or validity. We chose forty questions as a balance between coverage and a session most people finish in about six minutes.

The five axes

Four letters name the type. A fifth — Assured or Tidal — names how you tend to hold that type under pressure. Percentages are a lean, not a talent score.

The four preference pairs use classic Jung–Myers vocabulary as framework terminology. The fifth axis — Assured / Tidal (Typaria’s “Weather” axis) — is our implementation of an additional identity/confidence-style dimension. It has not been factor-analysed against an established scale, and it should be read as the least settled number on your result.

What research supports

• Personality is largely continuous. Independent research relating type indices to broader trait models finds continuous dimensions rather than neat either/or categories. Dichotomizing those dimensions into letters loses information near the middle.^{(McCrae, 1989)}
• Four-letter type instruments need cautious reading. Consulting psychology commentary has long urged care about reliability, validity, and over-interpretation of letter codes.^{(Pittenger, 2005)}
• Framework vocabulary is shared language. The Myers & Briggs Foundation documents E/I, S/N, T/F, and J/P as preference-pair terminology. That explains why many products use similar letters — it does not mean Typaria is affiliated with or validated by that foundation.^{(The Myers & Briggs Foundation, 2024)}

What research questions or challenges

• Type systems cut continuous traits in half. Most measured traits are distributed continuously, with many people near the middle. Someone at 51% and someone at 95% can share a letter; someone at 49% gets the opposite one.^{(McCrae, 1989)}
• Retest instability is a known concern. Preference instruments can flip letters for some people across sittings, especially near midpoints. Read a near-50% dimension as genuinely mixed.^{(Pittenger, 2005)}
• Reverse-keyed items are contested. Studies and reviews find mixed evidence: reverse wording may not automatically remove response bias and can introduce confusion or error.^{(García-Fernández, 2022)(van Sonderen, 2013)(Elek, 2025)}
• Self-report measures self-image. The test records how you describe yourself today, shaped by mood, context, and what you would like to be true.

What Typaria has not validated

• No published reliability (e.g. internal consistency, test–retest) for this item set.
• No criterion or construct validity study against established personality scales.
• No demonstration that reverse-keyed items improve measurement quality in this questionnaire.
• No empirical link between Typaria pairing scores and real-world relationship or workplace outcomes.
• The Assured / Tidal axis is an editorial construct, not an established psychometric scale.

Compatibility methodology

Each of the 120 pairing pages starts from a base of 46 and adds points per preference pair — 18 for a shared Sensing / Intuition preference, 11 for shared Thinking / Feeling, 9 for shared Judging / Perceiving, and 8 for opposite Extraversion / Introversion against 5 for matching. Scores land between 63 and 92. We call this a Typaria pairing score — a reading of the letters inside our model, not a scientific probability of relationship success.

Sensing / Intuition carries the most weight because, in type literature, it often frames what two people find worth discussing; energy direction carries the least and slightly favours difference as a common working pattern in editorial models. The function is symmetric: INTJ & ENFP and ENFP & INTJ are the same number and the same page. Do not use any compatibility model — including this one — to decide whether to date or hire someone.

Editorial policy

Typaria is written and maintained independently by named contributors — writers and engineers, not licensed psychologists. We do not claim clinical expertise or psychological review. Where the framework is contested, we say so on the page. We take no payment for placement, run no advertising, and have no affiliate links.
