eHarmony Has Turned To Quantum Physics To Improve Its Relationship Questionnaire

In a recent article, the University of Southern California’s (USC) School of Engineering explains how eHarmony is turning to methods inspired by quantum physics to improve part of its matchmaking system.

Hoping to facilitate long-lasting relationships, eHarmony uses a rather extensive relationship questionnaire to get to know users and offer them the best matches.

And although this questionnaire is now at 145 questions (down from 500), the dating platform feels more can be done to reduce its length.

So, eHarmony’s Dr Jonathan Morra and Jonathan Beber have now called on USC’s Aram Galstyan and Greg Ver Steeg to help whittle down the questionnaire using the process of correlation explanation (or CorEx).

Ver Steeg explains: “The idea behind CorEx is to ask what are the hidden factors that explain correlations in the data.

“For example, how different parts of your brain light up at the same time, or the way you answer question A always predicts the way you answer question B. It could be anything.”

Galstyan adds: “These hidden factors themselves are interrelated and reveal higher-level patterns in the data.

“Answers to questions like, how important is it that a serious relationship needs to be exclusive, and do you think being monogamous causes relationships to be boring over time, reveal something about how caring, empathetic and generous you are.”
