Instruments
Three instruments. One scale.
Each instrument measures the same five dimensions — at different depth and resolution. They are designed to be used in sequence, but each stands alone.
Quick snapshot
New Moon Cèrcol
10 questions · ~2 min
Five dimensions. One score per dimension. No facet breakdown.
A radar chart of your position on all five dimensions. Good for a quick orientation. Not precise enough for fine-grained claims about facets — that's what First Quarter is for.
Sample questions
I see myself as:
Extraverted, enthusiastic.
I see myself as:
Dependable, self-disciplined.
I see myself as:
Open to new experiences, complex.
7-point scale: 'Disagree strongly' to 'Agree strongly'. Each point carries meaning — not just two extremes with numbers in between.

First Quarter Cèrcol
60 questions · ~10 min
Five dimensions, each broken into 6 facets — 30 data points. Two items per facet.
Domain chart, 30-facet breakdown, and a first beta read on your role. The facet breakdown is where the useful information lives — the domain totals are just the headline.
Sample questions
I see myself as someone who:
Take charge.
I see myself as someone who:
Worry about things.
I see myself as someone who:
Have a vivid imagination.
5-point scale: 'Disagree strongly' to 'Agree strongly'. Five-point scales are standard for facet-level personality measurement.

Full Moon Cèrcol
Full Moon is a system of two parts used together.
Part 1 · Self-report
120 questions · ~20 min · 5-point scale
The same 30 facets as First Quarter — at twice the resolution. Four items per facet instead of two. In psychometric terms, more items per facet means more reliable scores, especially for facets near the centre of the scale where two items can give a noisy result.
I see myself as someone who:
Seldom feel blue.
I see myself as someone who:
Anticipate the needs of others.
I see myself as someone who:
Get chores done right away.
Part 2 · Witness Cèrcol
Why a Witness?
Self-reports have a known limitation: we don't always perceive ourselves the way we come across to others. People high on Depth may under-report — the emotion feels normal from the inside. People high on Bond may over-report warmth — the intent is genuine but the impact can differ. Self-assessment is a filtered signal. The Witness adds an independent one.
How it works
Each Witness receives a unique link. The task takes about 5 minutes. They see 20 rounds of 5 words — one adjective per dimension — and pick the one that fits best and the one that fits least. Forced choice: no Likert scale, no ability to give all positive answers.
Who is an ideal Witness?
Someone who has worked with you, lived with you, or seen you under pressure. Not your biggest advocate — someone honest enough to mark where you have edges. You can invite up to 12 Witnesses. More Witnesses reduce noise: the scores are averaged.
Privacy
Witnesses never see your scores. You see the averaged result from all Witnesses — not individual responses.
Blind spots
Where your self-report and Witness scores diverge significantly, a blind spot is flagged. Not because one is right and the other wrong — but because the gap itself is informative. A dimension you perceive very differently than those around you is worth examining.
