Scientific foundation - Big Five and 30 facets
Why the Big Five? To understand personality you need a reliable map. The Five Factor Model (Big Five) is the most research-validated model in modern psychology, the result of decades of studies across cultures and populations.
The five dimensions (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) provide a shared starting point. That alone is not enough.
The precision is in the details. Two people can both be highly extraverted. One can be dominant and decisive, the other warm and sociable. The difference is not visible in the main dimension; it shows up in the 30 underlying facets.
By analyzing facets such as "assertiveness" versus "sociability," or "dutifulness" versus "self-discipline," we create a detailed portrait of you specifically.
That precision is the basis for the next step: linking your profile to your actual situation.
