How Personica works

Personica editorial · 4 min read · Updated 24 September 2026

The instrument

The standard questionnaire contains 50 original statements, ten for each of five dimensions. The quick questionnaire contains 12: three each for openness and conscientiousness, and two each for extraversion, agreeableness and emotional sensitivity. Focused trait reflections use the ten standard statements for the selected dimension.

The wording is inspired by the Big Five framework. This is not the IPIP-50, NEO-PI-R or MBTI instrument. We have not published independent reliability, validity or representative norming data for this questionnaire. Evidence supporting a broad personality framework does not automatically validate our questions or interpretations.

Scoring, step by step

1. Responses range from 1 (strongly disagree) to 5 (strongly agree).
2. For a negatively keyed statement, the scored response is 6 minus the selected response.
3. Calculate the mean scored response within each trait.
4. Convert the mean using round((mean − 1) / 4 × 100).

Example: scored responses of 4 and 2 have a mean of 3, which becomes 50. Reverse-scoring means that disagreement with a negatively worded statement may raise the trait score.

Every item must have an integer response from 1 to 5. The report rejects missing, unknown and invalid answers instead of replacing them with neutral scores.

What a score means

A score describes your responses within this questionnaire’s possible range. A 75 is not the 75th percentile. Fifty is the mathematical midpoint, not a measured population average. The report uses scores below 40, from 40 to 60, and above 60 to choose editorial reflection prompts. These are interface choices, not validated psychological cutoffs.

Archetypes and four-letter codes

We split extraversion, openness, agreeableness and conscientiousness at 50. High extraversion maps to E and low to I; high openness to N and low to S; high agreeableness to F and low to T; high conscientiousness to J and low to P. Exact midpoints go to the high pole. Emotional sensitivity does not determine the archetype.

This mapping creates 16 illustrative categories. The codes resemble MBTI codes but are not an MBTI assessment or validated conversion. The report flags scores within ten points of a classifying midpoint. This is a proximity notice, not a statistical confidence interval or a reliability estimate.

Personalized interpretation

Each trait’s score selects a reflection on a possible strength, a trade-off and an exercise. A small set of combinations generates additional prompts. A default seven-day focus uses a score furthest from the midpoint; you can choose another. The advice is authored guidance, not an individually validated prediction.

Archetype profiles are illustrative guides. Their example trait ranges and associations with other frameworks are not population estimates. Use your actual scores and experiences when a general description does not fit.

Careers and comparison

The career explorer filters editorial role examples using activities you choose. It does not derive validated vocational interests from personality, rank 900 occupations, estimate salary or calculate a job-match percentage. O*NET links are external research resources.

Profile comparison subtracts one score from another and offers discussion questions. A difference does not establish compatibility or statistical significance. Different questionnaire lengths and different testing conditions make comparisons less direct.

Privacy and reproducibility

Scoring runs in the browser. Completed result links contain base64-encoded JSON with question IDs, answers, test mode, elapsed time and a timestamp. The fragment after # is not sent in ordinary HTTP requests, but anyone with the whole link can decode it. It is not encrypted. This release loads no ad or analytics scripts.

Version 7.0 keeps the original question IDs and trait scoring so complete version-1 result links remain readable. Career-interest numbers from the earlier derived model are no longer presented to users. Review privacy details before sharing.

Use and limitations

Self-reports depend on interpretation, context and memory. More questions do not by themselves prove reliability. Do not use this tool to diagnose conditions, select employees, determine ability or exclude careers. A change after retesting can reflect response variation rather than lasting personality change.
