eharmony's questionnaire captures your stated values, lifestyle preferences, and self-described personality. Psychometric self-report measures are useful and reasonably reliable. They are substantially less accurate than involuntary behavioural measures, which capture how you actually respond rather than how you perceive yourself.

Self-report vs involuntary response

eharmony's questionnaire measures your self-perception. Attune's emotion AI measures your actual involuntary responses. People consistently overestimate their own positive qualities and underestimate their emotional reactivity in self-report contexts. The gap between who you think you are and how you actually respond is where compatibility predictions fail.

Questionnaires can be gamed

Any self-report system rewards presenting yourself in a socially desirable way. Attune's FACS analysis cannot be gamed: involuntary facial micro-expressions occur faster than conscious control.

The right premise, wrong execution

eharmony was correct that compatibility matters more than physical appearance. Attune agrees — and uses emotional measurement rather than self-report to capture it more accurately.

eharmony had the right idea. Attune has better data.
