We hear all the time that love is chemistry. Hormone releases, brain chemicals, bursts of serotonin and oxytocin delivered at just the right moment. And if science and romantic relationships are so connected, why not use it? So we at Fitil have developed an algorithm that calculates the possibility of compatibility of members of our community.

What an algorithm

The registration of each user in our application begins with a test of 25 sociological and 92 psychological questions, developed on the basis of research by Lyudmila Sobczyk, a specialist in personality identification.

All questions are quite simple, the test takes 10-15 minutes. By answering these 117 questions about yourself, the user can get a psychological portrait with an analysis of weaknesses and strengths. It looks like this:

A psychological portrait is displayed in the form of a diagram with eight rays – character traits that a person possesses to one degree or another (an indicator of six means a clearly defined limit).

The test was developed on the basis of the works of a specialist in the field of personality identification, Doctor of Psychological Sciences, L.M. Sobchik, and it has been used by professional psychologists for over thirty years.

What is the test for? Despite the fact that the algorithm of compatibility of men and women is built on the basis of this test. Its effectiveness has been confirmed by more than 1,200 couples, and the algorithm itself not only calculates the percentage of compatibility, but also gives clear recommendations for building relationships.

Thus, after 15 minutes of registration, the user receives an analysis of his personality, a forecast of compatibility with other participants and access to the poster of events where he can meet them.

What does compatibility percentage mean?

This percentage reflects the possibility of building a harmonious relationship with a member of the opposite sex. The higher the percentage, the more comfortable and interesting the partners will be in the relationship, the easier it will be to negotiate and reach a compromise.

High compatibility – indicator from 60%. Users who are well compatible see each other like this:

Can the compatibility percentage change?

It can change: it can happen both due to updates in our algorithm, and due to passing the test.

1. For example, we are currently working on a small test change. This means that the algorithm will be slightly adjusted.

And in 2022, the percentage of compatibility was calculated based on the user’s ability to empathize – this is how we tested the hypothesis that a person with a high level of empathy better hears and understands his partner and is more likely to have a constructive conversation.

2. The user can retake the test an unlimited number of times.

We advise you to take a psychological test once every six months – or when a person has experienced strong changes in life.

For example, something happened that increased the general level of anxiety. Or extreme circumstances required to develop aggressiveness. The test helps track these changes, and the updated results allow you to provide other participants with the most relevant information about yourself.

For example, our designer Christina took the test for the first time in March 2022. And the second time – already in January 2023. It turned out that during this time she had softened her rigidity (a characteristic that manifests itself in the inertia of attitudes, subjectivism of thinking, critical attitude towards others). And indeed – Khrystyna says that during this time she became less categorical thanks to some life situations, she learns to look at them from different sides and life positions. And she also accepted the fact that she cannot influence absolutely everything, tries to listen to herself and reveal her abilities. It’s nice to be able to see the changes with the test results after working on yourself like this, isn’t it?

And let’s add about the sociological test: it is worth passing if you have changed your attitude towards life, smoking, alcohol – this also forms compatibility between people.

Let’s tell about one of our stories. In the spring of 2022, a couple formed in our community and are still together.

Volodymyr is a referent with pronounced sensitivity, Maryana is a theorist with overwhelming introversion. Their app compatibility is 65%. The theorist and the referent are a good and harmonious pair: the referent-empath is able to feel the introverted theorist, gently attract him to himself and get into the circle of his close people.

We met at one of the events — a tour of the art ghetto of Moscow. It was Maryana’s first event, and Volodymyr had attended sculpting, dancing and jazz before. And, as Volodymyr says, the relationship developed immediately: “apparently, we have a lot in common and we knew exactly who we were looking for.”

What else does the test give?

The high quality of the audience, which is much more important to us than the quantity.

The test screens out mentally unstable people and increases the chances of meeting a mature and reliable partner. And the fact that a person is ready to spend 15 minutes on passing the test confirms his desire to be in the community and desire for mature relationships.

Conclusion

Love cannot be measured, but you can calculate the probability with which people will be able to understand each other – and this is already a good basis for a relationship. Is there a chance of success for a couple with compatibility below 60%? It is quite possible: low compatibility only means that partners will have to make much more effort to overcome crisis situations. And if you want harmony and to be on the same wavelength – welcome to Fitil.
