Method & research
Two people read the line “I stay calm under pressure.” Both tap Strongly agree. One of them has not raised their voice in a year. The other is hoping that saying it makes it true.
How it works, and what it can’t tell you
Before reading on: what one change to the question would tell these two apart?
The obvious fix is a finer scale, or more questions. That makes sense: more detail usually means more signal. But both people can still see which answer sounds best, and a finer scale only gives them more room to pick it.
Calmistry takes the flattering answer away instead. Each round shows one small scene and four reactions to it, all about equally likeable, and asks which is most like you and which is least. Nobody can pick all four, so every choice trades off against the others. Across many rounds those trade-offs add up to a pattern: what tends to get through, how strongly it lands, what happens next, how long it stays and what helps it leave.
Give the two people from the first line one round of four, and their taps split. One picks “I say it plainly and move on.” The other picks “I go quiet and hold it.” Neither answer is better. They are different, and now the difference shows.
A rule for any test you take
Ask: could I have picked the answer I wanted to be true? If yes, read the result as a wish, not a measure.
Where the evidence stops
What is known, what we propose, and what we are still testing
Calmistry by Think North is an exploratory stress-mechanics self-assessment and research project. This is where published research ends and our own ideas begin, in plain words.
-
Known: published research
Findings about stress, emotion and recovery from peer-reviewed studies, each cited with who was studied and how. We keep them apart from our own ideas.
-
Proposed: the 13 measures
Our proposed way of describing how pressure moves through a person. Each one borrows an idea from published research. They are under validation, and none is a validated scale yet.
-
Proposed: the 12 materials
Closest-match interpretations of your answer pattern, not established categories or types. When the match is weak, or two materials sit close together, your result says so.
-
Our own questions
Every scene and reaction was written by Think North. We don’t reproduce published questionnaires: research shaped what we ask about, not the wording.
-
A fixed calculation
Your result is worked out from your answers by the same fixed calculation for everyone. The same answers, on the same version of the questions, always give the same result. Nothing else goes in.
-
Not validated yet
We have not yet shown, with real people, that the questions hang together, give the same answer twice, or tell you more than existing questionnaires do. We are testing this by asking people to answer again weeks later, comparing answers with a free public personality questionnaire, checking the questions work the same for different groups, and adding views from people who know you.
-
Practices: a hypothesis
Each practice we suggest has general research behind it. Matching one to your pattern is our hypothesis: evidence that a practice helps is not evidence that matching it to your material helps more. Try it, and keep what works for you.
-
Not a clinical test
Calmistry is not a clinical or diagnostic test. It can’t rule anything in or out, and it doesn’t tell you how much stress you are carrying right now.
What is measured
One load, five stages, 13 measures
Every result follows pressure from the moment it arrives to the moment it leaves. Calmistry borrows the words engineers use when they load-test a material: we borrow the vocabulary, not the physics. Each measure has one plain-words definition, used the same way on every page.
Stress material: Calmistry’s metaphor for a person’s recurring pattern of response to pressure, across several measured dimensions.
-
What gets in
Does stress bounce off, sink in or go straight out, and how much of other people’s moods gets in?
- Bounces off (Reflect) Bounces off: how often stress meets a boundary first, a joke, a shrug or a calm ’not mine’, before it gets any further in.
- Sinks in (Absorb) Sinks in: how often stress goes inward first and gets held quietly, so you go still and process it inside before anyone else sees it.
- Goes straight out (Transmit) Goes straight out: how often stress leaves quickly as words, visible emotion or immediate action, so you say it, show it or do something before it settles inside.
- How much of the room gets in (Porosity) How much of the room gets in: how much of other people’s moods and a room’s atmosphere gets into you without being invited.
-
What changes when it hits
How much it takes to move you, when it starts to count, how far you bend and whether pressure turns into action.
- How much it takes to move you (Stiffness) How much it takes to move you: how strongly you hold to a set plan, route or expectation once it is in place, and how much changing it costs.
- When it starts to get serious (Yield point) When it starts to get serious: how much load builds up before stress registers with you as stress, from the first small hitch to well past a heavy deadline.
- How far you bend without breaking (Ductility) How far you bend without breaking: whether strain shows gradually over days as you signal and adjust, or stays hidden until it suddenly comes out all at once.
- Whether pressure turns into action (Piezo) Whether pressure turns into action: how often pressure makes you produce something, such as a plan, a list, a fix, a joke or a piece of work, rather than pausing the making.
-
What repeats do
Whether the second time gets easier, whether small hits add up, and what a load that never leaves does.
- Whether repeats make you tougher (Work hardening) Whether repeats make you tougher: whether a hard thing gets easier the second and third time, or still needs a fresh start each time.
- How repeats wear on you (Fatigue) How repeats wear on you: how much many small, repeated stresses add up for you, from a drip that gradually wears you down to small things rolling off.
- How slow, long pressure wears on you (Creep) How slow, long pressure wears on you: how much one heavy load carried for months, such as caregiving, exams or a long project, slowly changes you.
-
What stored stress does
How long it stays and what is still left afterwards.
- How long it stays (Half-life) How long it stays: how long it takes you to get back to your usual baseline after something stressful has passed.
- What’s left afterwards (Residual stress) What’s left afterwards: how much stays with you once a stressful moment is over, such as replayed conversations, unfinished business and leftover tension.

What recovery looks like for you
Practices from families that tend to help, matched to the pattern the measures describe.
Why we ask this way
Harder to game, not impossible
Rating scales (“agree 1 to 5”) are quick, but they invite everyone to agree with whatever sounds good. Forced choice between equally likeable reactions removes the easy flattering answer, and reviews of high-stakes testing find it harder to fake than rating scales, though not immune to it.
It has costs too. It takes longer per round, some rounds feel like choosing between two things that are both true of you, and it is still you describing yourself. People are not always good witnesses of their own reactions, which is why we are adding ratings from people who know you (see “What has been validated”).
So we make a narrower promise than most quizzes: the questions are built so that picking the answer you would like to be true is harder. We do not claim the result is the real you. It is a description of your answers, made as hard to tilt as we could.
What has been validated
Formally, nothing yet. Here is what we have and what is next.
What we have now
- Simulated recovery. We generate thousands of answer sets from known profiles and check whether the scoring gets the profiles back. On the full profile it recovers the measures reasonably well. That shows the arithmetic works; it says nothing yet about real people.
- Materials are labels, not types. In the same simulations, the closest material comes back the same on a retake only about half the time, and the profiles do not fall into twelve natural clusters. So the 12 materials are labels on a smooth range, and the 13 measures are the real output. That is why every result shows the measures and a runner-up.
- Content checks. The blind sort and desirability ratings described above. They check that statements say what they are meant to say, not that the measures predict anything.
Planned, and reported whatever we find
- Does it hold together? Whether real answers fit the intended structure, measure by measure.
- Same answer twice? Test–retest: the same people answering again a few weeks later.
- Does it agree with known measures? Comparison with a public-domain Big Five short form, for the measures that should relate to it, and not for those that shouldn’t.
- Fair across groups? Whether questions work the same way across age, gender, device and the two wordings.
- What do people who know you see? Short ratings from a friend in a pair compare, set against your own answers.
Results will be shared as preprints and summarised on this page, including the parts that don’t work.
Questions
Questions people ask first
Is this basically a personality test?
No. A personality test describes you in general. This looks at one thing: what your system tends to do once pressure lands. That can differ at work and at home, and it can shift over a few months.
Can my material change?
Yes. It names a recurring response pattern, not a fixed trait. Sleep, support, a long wait or a new job can all move it. Take it again in a few weeks and compare.
Why would the same person show different patterns in different situations?
Because the load is different. A deadline and a family dinner press in different places, and each situation quiz looks at one kind of pressure. That’s why two quizzes can name different materials. The full profile reads all 13 measures together.
What does Calmistry actually measure?
Thirteen measures of how you respond to pressure, grouped into five stages: what gets in, what changes when it hits, what repeats do, what stored stress does and what recovery looks like for you. Each comes from your choices between reactions, not from rating yourself 1 to 5.
Has Calmistry been clinically validated?
No, and it hasn’t been validated in any other way yet either. The question format (choosing between equally likeable reactions) and the kind of scoring model come from published measurement research, but our own questions are new and untested with real people. We haven’t yet shown that results stay stable over time or line up with established measures. We’re collecting that data now and will publish what we find, either way. It isn’t a clinical or diagnostic test.
Is this a diagnosis?
No. It’s a way of seeing your patterns. If something feels heavy, talk to someone you trust or a doctor.
How long does it take?
About 12 minutes for a quiz: each round asks you to pick two of four reactions. The full profile takes about 40 minutes, you can pause it, and rounds you’ve already answered in a quiz aren’t asked again.
