What a compatibility test actually measures
A good test predicts neither the length nor the “worth” of a relationship. It makes often-implicit preferences visible: daily pace, how you talk, intimacy needs, priorities, future vision, how you handle tension.
A useful result is an alignment score between two profiles, with detail by theme. It is a snapshot, not a diagnosis. A gap on one theme can be as interesting as agreement: it names a conversation to have.
Be wary of tests that promise a magic percentage or a “soulmates” verdict. Prefer a transparent method: named themes, separate answers, reading the result together.
