Personality test results explained: percentages and type changes
Start with the four pairs of scores, then look at the letters. This guide explains the OpenJung result display and helps you choose something useful to try in a real conversation or decision.

What the percentages mean
Each percentage shows where a dimension score falls between the two ends of the scale. The two sides add up to 100% by construction. They do not show the percentage of questions answered a certain way, your rank among other people, or the probability that a type is correct.
For example, an E/I score of 32 becomes I 75% and E 25%. That describes the position of this score; it does not mean you are introverted in 75% of situations. A larger percentage does not establish ability, accuracy or future behavior.
These examples use the current OpenJung implementation. OpenJung adapts item wording and directions. These are its display rules, not a reproduction of every rule in the original questionnaire.
| Dimension score | E | I | Letter |
|---|---|---|---|
| 8 | 100% | 0% | E |
| 24 | 50% | 50% | E |
| 25 | 47% | 53% | I |
| 32 | 25% | 75% | I |
| 40 | 0% | 100% | I |
Reading scores near the midpoint
In the current full test, an E/I score of 24 displays E 50% and I 50%, with the letter E. A score of 25 displays E 47% and I 53%, with the letter I. The letter changes because the score crosses the cutoff. The equal result does not establish a stronger preference for E.
The result summary marks 45–55% as near the midpoint. This is a reading aid, not a statistical confidence interval or a measured uncertainty range. Being outside this band does not establish that your type is certain or will stay the same.
Check the assessment mode and version
The full test has 32 questions, with 8 per dimension. The quick test has 8 questions, with only 2 per dimension. Both use five-point answers.
Full dimension scores range from 8 to 40. Quick scores range from 2 to 10 and are multiplied by four for the same display range. Sharing a display scale does not establish equal precision. One answer can move a quick-test percentage further because there are fewer questions.

Before comparing results, check their mode and version. If an older link does not record them, treat those details as unknown. Choosing the full test gives you more questions to reflect on; neither mode has published validation for this OpenJung adaptation.
When a result changes
- Check whether you used the same test, mode and version. Percentages from other tests may use different calculations.
- Compare each pair of scores before comparing the four-letter code. Notice whether a score crossed the midpoint.
- Think about the situation you had in mind and which answers felt context-dependent. A result alone cannot tell you why your answers changed.
The cutoff example explains how a letter can change after a small score change. It does not show how often this happens or establish the stability of the underlying scores. OpenJung has not published test–retest findings for this version, its quick test or its translations.
Try one practice, then review what happened
Choose a situation that matters to you, rather than an action prescribed by a type. For example, you can try this existing practice regardless of your four letters:
Listen before offering a solution
In your next conversation, ask whether the other person wants you to listen or help find options. Summarize what you heard and check that you understood.
After trying it, ask yourself: What did you understand differently after listening and checking?
In My space, open Weekly review, choose one practice and save it. After trying it, open your practices to record what happened. Weekly review brings together saved reflections from the last seven local calendar days and your currently active practices, so you can choose what to try next.
Practices and reflections stay in this browser. No account is required, and research and usage sharing can remain off. This guide does not read your saved results.
Sources and their limits
- OEJTS 1.2 questionnaire and scoring instructions (2015)
The original PDF identifies a 32-item questionnaire and its scoring rules. It licenses the items under CC BY-NC-SA 4.0. It is not a validation report for OpenJung or its quick test.
- Open Psychometrics item-development background
This page describes selecting items using participants’ self-reported types. It includes differing 48-item and 40-item descriptions, so its participant count should not be read as validation specifically of the 32-item 1.2 form or this adaptation.
- OpenJung scoring source for the examples
The linked implementation supplies the percentage conversion and letter cutoff used above. Source code makes those rules inspectable; it does not establish measurement validity.
