Being compatible does not mean being alike. It means wanting the same life where it matters, knowing how to compromise on the rest, and agreeing on what is not negotiable. The difficulty, before a marriage, is to tell these three levels apart: the values that steer a life, the preferences that colour it, and the non-negotiables that close it. This article offers a method for untangling them, and explains how a calculated compatibility can help you talk about them — without ever deciding in your place.
Values, preferences, non-negotiables: what is the difference?
| What it is | Example | What you do with it | |
|---|---|---|---|
| Value | A principle that steers choices, often inherited and thought through | "Family comes before career" | You discuss it: how does it translate into a week, a year, a crisis? |
| Preference | A taste, a comfort, a habit | "I would like to live near my parents" | You talk about it, you negotiate, you may give it up |
| Non-negotiable | A condition without which the marriage makes no sense to you | "I want children" | You state it early and clearly, and you listen for the other person's |
The most common mistake is to present a preference as a non-negotiable — for fear of giving in — or a non-negotiable as a preference — for fear of scaring the other person off. In both cases, the conversation starts on a false footing. The remedy is simple: before meeting anyone, write down your own answers, and be honest about which column each belongs in.
Which values should you discuss first?
The values worth discussing are those that produce decisions. Here are twelve frequent reference points, each with the question that makes it concrete. This is not a form to fill in, but a map so that nothing is forgotten.
- Family — What place for parents, brothers and sisters, the children to come, in your time and in your decisions?
- Faith — How does practice fit into the days, and what do you expect of each other on that point?
- Stability — Do you prefer a predictable frame, or do you accept uncertainty for the sake of a project?
- Career — Is work a means, or part of who you are? For one of you? For both?
- Independence — How much autonomy does each of you need: time, money, decisions?
- Generosity — How do you give: time, money, hospitality? To whom, how far?
- Ambition — What do you want to have achieved, and at what price?
- Education — How much importance do you give to studies, culture, passing things on?
- Community — Do you live turned towards a wide circle, or rather in a small one?
- Simplicity — What is your relationship with comfort, consumption, appearances?
- Openness — How do you welcome what is different: origins, backgrounds, ideas?
- Spirituality — Beyond the rites, what place for inner life, silence, meaning?
You will not give each of these the same weight, and neither will the other person. That is precisely what you need to discover: not a list of shared values, but a shared — or compatible — hierarchy.
Note. Two people can share all these values and fail, because they do not know how to talk to each other; two people can differ on several and succeed, because they do. Values say where you want to go; they do not say how you travel together. Hence the point of also discussing how each of you handles a disagreement.
Why is religious practice not "scored"?
Some services offer to filter or rank profiles by "level of practice". This approach raises a problem of substance and a problem of law.
The problem of substance: practice is a trajectory, not a plateau. It changes with age, with hardship, with the people around you. Reducing it to a scale means comparing snapshots and getting the people wrong.
The problem of law: data revealing religious beliefs belong to the special categories of personal data under Article 9 of the GDPR — what the CNIL, the French data-protection authority, calls sensitive data — and enjoy heightened protection. The regulation applies across the EU, and each country has its own supervisory authority. A serious matrimonial service handles such data with that requirement in mind, and does not turn it into a score.
On Nikaa7, religious practice is described in your own words, in a free-text field, without scale or level; it never enters a compatibility calculation, nor a ranking. It belongs to the conversation, not to the algorithm.
How does Nikaa7 approach compatibility?
Compatibility there rests on what each person declares: their values, chosen from a shared vocabulary, their life plans, their personality, their family and geographical situation. Three principles govern the calculation:
- It is deterministic and versioned. The same information gives the same result, and it is known which version of the calculation produced what. No language model is involved.
- It ranks, it does not decide. The result serves to order plausible proposals between people who are already eligible; it neither permits nor forbids anything. Every proposal is reviewed by a counsellor before it is presented to you, and the counsellor can set it aside.
- It explains itself. A proposal comes with its points in common and its points to discuss, dimension by dimension. These are subjects for conversation, not a verdict.
Your expectations are declared at three levels — preference, important, non-negotiable — and only the last becomes a constraint, respected in both directions: your non-negotiables protect the other person as much as you. Finally, every surface that displays a compatibility reminds you that it is an estimate, not a guarantee. Nikaa7 supports; it does not decide.
Which practical exercises can you do before a meeting?
The three-column list
Take a sheet of paper. Three columns: values, preferences, non-negotiables. Fill them in on your own, without thinking about what "would look good". Then reread: are there more than three non-negotiables? Some are probably preferences in disguise. Is the values column empty or vague? Go back to the list of twelve reference points above.
The story of an ordinary week
Write, in a few lines, an ordinary week of your married life a few years from now: getting up, work, meals, prayer, family, the weekend. Not the ideal week — the normal week. Ask the person you have met to do the same, then compare. Abstract values suddenly become very concrete: who cooks, who commutes, where the parents are, how much time for yourself.
The imaginary disagreement
Choose a plausible scenario — a job offer abroad, a sick parent who has to come and live with you, a large unplanned expense. Each of you says what you would do, then how you would like the decision to be taken. You will learn not only what the other person thinks, but how he or she decides.
Frequently asked questions
How do you know whether you are compatible on children, the extended family or where to live?
By making each subject concrete. "Do you want children?" calls for a yes; "How do you picture the mornings with two children and two jobs?" calls for a vision. Where to live, the place of parents and both spouses' work are the points where values collide with reality: those are the ones to tackle with the story of an ordinary week.
Can a compatibility calculation be wrong?
Yes, and it must be presented as such. It knows only what you declared, at the moment you declared it; it knows nothing of how you talk, listen and change. That is why it ranks proposals without deciding any of them, why a counsellor reviews every proposal, and why the final decision always belongs to you.
