How the ICA personality test works
Four dimensions, three faculties, one ranked profile. Here is every step, including what the scores can and cannot tell you.

Forty situations across eight areas of life
Each item describes a concrete situation with four responses. You choose what you would actually do. The 40 items are spread evenly across eight areas, five each:
| Items | Area | What it covers |
|---|---|---|
| 1–5 | Daily orientation | How you begin and organize your day |
| 6–10 | Problem-solving | How you approach problems |
| 11–15 | Social interaction | How you engage with people around you |
| 16–20 | Learning | How you take in new information |
| 21–25 | Decision-making | How you choose between options |
| 26–30 | Stress response | How you handle pressure |
| 31–35 | Creative expression | How you create |
| 36–40 | Relationships | How you connect and maintain bonds |
Scoring in four steps
- Count your answers. Count how many times you chose A, B, C and D. The four counts total 40.
- Convert to dimensions. A is Integrative Synthesis (IS), B is Systematic Analysis (SA), C is Social Attunement (SO), D is Environmental Engagement (EE).
- Calculate faculties. Thinking = IS + SA. Feeling = SO. Willing = EE. The three also total 40, and the highest is your dominant faculty; two within 2 points of each other are reported as dual-dominant.
- Rank the dimensions. First is primary, second supporting, third developing, fourth latent. The order is your profile code, for example IS-SA-SO-EE.

Take the free testThe Orientation Strength Index
The index shows how clearly your first dimension leads: (primary score minus supporting score) ÷ 40 × 100.
| Index | Level | What it suggests |
|---|---|---|
| 0–10% | Balanced | Your dimensions are evenly distributed. You adapt flexibly to different situations. You may feel like different contexts bring out different sides of you. |
| 11–25% | Clear | You have a recognizable preference but can access other dimensions when needed. You are versatile but have a comfort zone. |
| 26–40% | Strong | Your primary dimension clearly leads. Other dimensions serve it. You have a distinct way of approaching the world. |
| Above 40% | Very Strong | Your primary dimension dominates. You have a powerful and specific way of engaging with the world. |
What the scores mean, and what they do not
The four scores always add up to 40, so a higher score on one dimension means lower scores on others. Psychometricians call this ipsative scoring. It describes the balance of preferences within you; it cannot say how much of a trait you have compared with other people, and it supports no percentiles.
Choosing between options reduces some response habits, such as agreeing with everything, but no self-report questionnaire is immune to wanting to look good or to limited self-insight. In high-stakes settings, a meta-analysis found that forced-choice questionnaires inflated scores far less than rating-scale questionnaires, with an overall effect size of 0.06 (Cao & Drasgow, 2019).
Thinking is measured through two dimensions and Feeling and Willing through one each, so Thinking has two routes to a high faculty score. Your dominant faculty and your primary dimension can therefore differ; the result page shows both.
The research behind it
The faculties come from the long tradition of dividing the mind into thinking, feeling and willing, from Rudolf Steiner and the 18th-century "trilogy of mind". Each of the four dimensions has a parallel in three fields: Jung's analytical psychology, behavioral science and neuroscience.
Integrative Synthesis (IS)
- Analytical psychology
- In Jung's analytical psychology, intuition perceives possibilities and patterns rather than concrete detail (Jung, 1921).
- Behavioral science
- Dual-process research separates fast, intuitive, associative thinking from slow, deliberate reasoning; Integrative Synthesis sits on the intuitive, pattern-seeing side (Evans & Stanovich, 2013).
- Neuroscience
- The default mode network is active during self-referential thought, remembering and imagining the future (Buckner et al., 2008). Its role in openness to experience is an active research area (Dubois et al., 2018).
Systematic Analysis (SA)
- Analytical psychology
- Jung's thinking function judges by logical connection and principle (Jung, 1921).
- Behavioral science
- Dual-process research describes deliberate, rule-based reasoning, and the Rational-Experiential Inventory measures a preference for this analytical style (Pacini & Epstein, 1999).
- Neuroscience
- The executive control network (frontoparietal) supports working memory, planning and goal-directed reasoning (Seeley et al., 2007).
Social Attunement (SO)
- Analytical psychology
- Jung's feeling function judges by value and relationship; Social Attunement focuses on its interpersonal side (Jung, 1921).
- Behavioral science
- Behavioral science studies empathy and agreeableness as stable differences between people; Social Attunement is expected to relate to Agreeableness.
- Neuroscience
- Mentalizing, understanding what others think and feel, engages a network including the medial prefrontal cortex and temporoparietal junction (Frith & Frith, 2006).
Environmental Engagement (EE)
- Analytical psychology
- Jung's sensation function perceives concrete, present reality through the senses (Jung, 1921).
- Behavioral science
- Behavioral science distinguishes action-oriented, experience-led styles; Environmental Engagement is expected to relate to the active, assertive side of Extraversion.
- Neuroscience
- The sensorimotor network was among the first brain networks identified at rest (Biswal et al., 1995), and links perception directly to action.
These parallels shaped how the four dimensions were defined. The current study tests the ICA's structure, its stability over time and its relationships with established behavioral measures.

Common questions
How is it scored?
Each answer letter maps to one dimension: A to Integrative Synthesis, B to Systematic Analysis, C to Social Attunement and D to Environmental Engagement. Your four counts always add up to 40. Thinking is Integrative Synthesis plus Systematic Analysis; Feeling is Social Attunement; Willing is Environmental Engagement. Ranking the four dimensions gives your profile.
What happens when two dimensions tie?
Tied dimensions are listed in A, B, C, D order, and the result page shows the other profiles the tie allows. Close or tied scores mean your profile is less settled; a retake may differ.
Why does Thinking have two dimensions?
Because thinking works in two modes: seeing wholes and analyzing parts. Behavioral science draws the same line between intuitive and deliberate thinking, and Jung's analytical psychology between intuition and thinking. It gives Thinking two routes to a high score, so the result page shows your faculty scores and your four dimension scores side by side.

Ipsative scores total the same for everyone, so they compare your own preferences, not you with other people. What that means for forced-choice tests.
