Open-source personality assessment
See yourself more clearly.
Cèrcol is three instruments built on public-domain science. Each measures the same five dimensions — at different depths. No score tells you what to think. No result is good or bad.
Every contribution matters. No one is indispensable, but all of us are necessary.
Built in the open
Most personality assessments are proprietary. The items, the scoring, the normative data — behind paywalls or NDAs. You take the test, get a result, and have no way to know if the algorithm is sound. Cèrcol is different. Every question comes from public-domain research. The scoring is on GitHub. Anyone can read it, question it, and improve it. We think personality assessments should work that way.
Go deeper
Five dimensions
Every score sits on a spectrum. Both ends are valid — they describe different ways of being effective.
Presence
How much energy you direct outward. High: you bring people in. Low: you go deep with fewer.
Bond
How you connect and cooperate. High: you prioritise trust and harmony. Low: you hold your ground.
Discipline
How you approach structure and work. High: reliable, methodical. Low: flexible, instinct-driven.
Depth
How intensely you process stress and emotion. High: sensitive, alert. Low: stable, hard to rattle.
Vision
How much novelty and complexity you seek. High: creative, exploratory. Low: practical, grounded.
What Cèrcol is not
- —A diagnostic tool. These results have no clinical validity.
- —A fixed label. Scores shift with context, time, and state of mind.
- —A ranking. No dimension is better or worse than another.
- —A predictor of success. Tendencies describe how you tend to operate — not what you'll achieve.
A note on scores
These are tendencies, not labels. The same trait that creates friction in one context is exactly what's needed in another. Low Discipline isn't failure — it's often what keeps things moving when the plan falls apart.
