66 questions: 10 for each personality dimension, plus relationship-pattern items
The five BIG5 factors (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) are measured with
10 items each, reversal items included, and analyzed in precision on a 0–100 score.
"This is the detailed-question mode. It includes more questions, but that does not establish validation for research or clinical use. Take your time."
There are 66 questions, taking about 7 minutes. Compared with the 44-question standard version, this mode uses 10 items per personality dimension and includes five score bands, profile shape and paired-factor interpretations. These are the site's interpretations, not a certification of accuracy or validity.
The outward type (32 characters) and the hidden type (your other face, your attachment style) are determined at the same time.

ABOUT THIS TEST
The Precision version takes each of the five factors and breaks it down into finer sub-aspects (facets). For example, the same "high imagination" shows up in daily life completely differently depending on whether the fantasy is rich, the sensitivity to beautiful things is strong, or the leaning is toward intellectual inquiry. Two people with the same total score have different contents inside — separating that is the Precision version's job.
This way of dividing follows the facet structure that personality research has confirmed again and again. The finer the division, the easier it becomes to judge what fits and what does not.
If this is your first time, it suits you to start with the Standard version (44 questions) to get the whole picture. The Precision version suits people who felt that the standard version's result had parts that fit and parts that did not. It is a quiz for breaking down the self that looks contradictory.
Because there are many questions, you may stop partway if you get tired. Answers are used only to calculate your result and for anonymous statistical aggregation. This is not a medical examination; if daily life is being affected, please give priority to consulting a professional institution.

Analyzing 5 factors × 10 items each, plus the 2 attachment axes
So far, the focus has been on what may be happening for the other person. What happens on your side of a relationship deserves its own reflection too.
What you are watching now Big 5 Precision (66 questions, about 7 minutes). Quizzes differ in role by what they measure and how far in they go. In the chart below, check where you are now and which one will mesh if you take it next.
The Precision version measures each of the five factors with 10 items, 66 questions in total. Some of the items are designed as reversal items, so that answering everything in the same direction produces an internal inconsistency. This is a standard technique for keeping answers consistent, and it prevents a mechanically answered result from looking highly accurate. It takes longer, but the reliability of the scores rises accordingly.
The Precision version shows each factor's score band in five steps, and further analyzes the shape of the whole profile and the combinations of factor pairs. For example, high Conscientiousness alone makes a planful person, but when high Neuroticism is layered on top of it, exhaustion from perfectionism becomes likely. The same high score means something different depending on what is next to it — this is the part you cannot see by looking at single factor scores alone.
The Precision version shows each factor not as simply high or low but as one of five score bands. That is because the same "high" comes out in daily life quite differently depending on whether you are in the top twenty percent or the top half. Conscientiousness and Neuroticism in particular can reverse in meaning between a moderate state and an extremely high one. Moderate Conscientiousness works as steadiness, but at an extreme it appears as a perfectionism that cannot get started.
Personality appears not in single factors but in combinations. Someone high in Extraversion and low in Agreeableness is a leader, while someone high in both Extraversion and Agreeableness is sociable — the same high Extraversion changes meaning with the factor next to it. The Precision version analyzes these factor-pair combinations and the shape of the whole profile. Rather than rejoicing and grieving over single scores, grasping it as a shape is more practical.
By measuring the five factors with 10 items each, reversal items included, the score can be calculated while checking the consistency of the answers. Cutting the number of items makes the score-band judgment coarser, and factors in the middle band do not come out correctly. It takes around 10 minutes, but the reproducibility of the result is higher for it.
In addition to each factor's score, the Precision version analyzes the shape of all five factors together. A flat shape with every factor moderate, a shape where only one factor stands out, a shape split into two poles — the strengths and challenges that tend to appear differ by shape. Rather than the height of single scores, looking at this shape gives a better fit with daily life.
The accuracy of a personality test is roughly proportional to how many questions support a single factor. When there are few questions, the situation that happens to come to mind sways the result. Increasing the number of questions mixes in several situations — work scenes, home scenes, scenes alone — so situation-dependent wobble cancels out and the person's average tendency surfaces. This averaging is why the Precision version is worth the time it takes.
Even the same person taking it on a different day will normally move a few points on each factor. So the difference between 63 and 67 has no meaning; what has meaning is a difference of band, such as the 30s versus the 70s. When you handle the result, rounding it to the three steps of high, moderate and low rather than the fine numbers keeps you closer to reality. Personality traits are also known to change slowly with age, and Conscientiousness in particular has repeatedly been reported to rise as people get older.
