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 model or the HEXACO model are not enough for predictive purposes. That is why I suggest the 16PF5 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 16PF5 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry.

Fernando Ardenghi's List of Firsts:

First person in the World to say the entire Online Dating Industry in 1st World Countries is a HOAX.

First person in the World to say many Online Dating sites like eHarmony, PerfectMatch, Chemistry, PlentyOfFish Chemistry Predictor, MeeticAffinity, Parship, Be2 and others are performing as placebo, like patent medicine.

First person in the World to discover the Online Dating Sound Barrier problem.

First and Only person in the World to solve the Online Dating Sound Barrier problem.

First person in the World to suggest the normative 16PF5 test or similar like 15FQ+ to measure personality of daters instead of ipsative tests like PerfectMatch or Chemistry or other normative less powerful tests like the Big5.

First person in the World to say Online Dating sites should check if women are taking contraceptive pills or other hormonal therapy.

First person in the World to reverse engineering several online dating sites offering compatibility matching methods.

First person in the World to notice Personality Based Recommender Systems are like compatibility matching engines.

First person in the World to suggest Online Dating sites should show Compatibility Distribution Curves to every and each dater.

First person in the World to compile research about Theories of Romantic Relationship Development.

First person in the World to openly say Conferences for the Online Dating Industry like iDate and ODS are rubbish.

Do you think you can innovate and revolutionize the Online Dating Industry without taking into account the above list? No way.
