PAPER: Testing, filtering, and insinuating:
Matching and attunement of emoji use patterns as non-verbal flirting in online dating

The key to long-lasting romance: COMPATIBILITY is exactly STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests or political views".  
 
Online Dating sites have very big databases, in the range of 20,000,000 (twenty million) profiles, so the Big Five normative model or the HEXACO normative model are not enough for predictive purposes. That is why I suggest the normative 16PF6 test instead and another method to calculate similarity.

High precision in matching algorithms is precisely the key to open the door and leave the infancy of compatibility testing.
 
Without offering the NORMATIVE 16PF6 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry
