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 16PF6 test instead and another method to calculate similarity.

The key to long-lasting romance: COMPATIBILITY is exactly STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests or political views".  


Contradictory information from eHarmony and PROOF of FRAUD from the papers they had published using the OBSOLETE NORMATIVE PERSONALITY TEST BIG FIVE.
BIG FIVE NORMATIVE TEST WAS REVEALED AS INCORRECT AND INCOMPLETE MODEL OF PERSONALITY !!!

The Rise of Online Dating, and the Company That Dominates the Market ?

Psychiatrist warns 'gamification' of dating apps is harming our chances of finding love
https://onlinedatingsoundbarrier.blogspot.com/2019/03/psychiatrist-warns-gamification-of.html  


 
Lack Of Innovation & Decadence can summarize the Online Dating Industry.
C-Level executives are more worried about their golf scores than their company’s long term strategy and innovations.
C-level executives are cooking barbecues under the water (selling smoke) and not paying attention to latest research from Academics which could be beneficial for the Online Dating Industry. 


WorldWide, there are over 5,000 (five thousand) online dating sites:

- but no one is using the 16PF5 (or similar) to assess personality of its members!

- but no one calculates similarity with a quantized pattern comparison method!

- but no one can show Compatibility Distribution Curves to each and every of its members!!! i.e. if you are a man seeking women, to show how compatible you are with a 20,000,000 women database, and to select a bunch of 100 women from 20,000,000 women database.

- but no one is scientifically proven!  No actual online dating site  is "scientifically proven" because no one can prove its matching algorithm can match prospective partners who will have more stable and satisfying relationships (and very low divorce rates) than couples matched by chance, astrological destiny, personal preferences, searching on one's own, or other technique as the control group in a peer reviewed Scientific Paper for the majority (over 90%) of its members.


The Online Dating Industry does not need a 10% improvement, a 50% improvement or a 100% improvement. It does need "a 100 times better improvement"

Personality Based Recommender Systems are the next generation of recommender systems because they perform far better than Behavioural ones (past actions and pattern of personal preferences)

That is the only way to improve recommender systems, to include the personality traits of their users.
http://onlinedatingsoundbarrier.blogspot.com.ar/2017/01/paper-comparative-study-of-people-to_14.html  

They need to calculate personality similarity between users but there are different formulas to calculate similarity.

In case you did not see, recommender systems are morphing to compatibility matching engines, as the same used in the Online Dating Industry for years, with low success rates until now because they mostly use the Big Five model to assess personality and the Pearson correlation coefficient to calculate similarity.
Please remember: Personality traits are highly stable in persons over 25 years old to 45 years old. 

The key to long-lasting romance: COMPATIBILITY is exactly STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests or political views".  

Which is the RIGHT approach to innovate in the Personality Based Recommender Systems Arena? 
The same approach to innovate in the Online Dating Industry == 16PF6 test or similar to assess personality traits and a new method to calculate similarity between quantized patterns.
 

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 16PF6 test instead and another method to calculate similarity.

The Big Five normative personality test is obsolete, it has been proven as an incomplete and incorrect model of personality.
The HEXACO (a.k.a. Big Six) is another oversimplification. 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.

http://onlinedatingsoundbarrier.blogspot.com.ar/2016/10/very-easy-to-copycat-eharmony-but-very.html 


eHarmony is ONLY a 19  years old obsolete site and a HOAX, based on a big scientific fraud, only sustained by big marketing budget.
The Big Five normative test used by eHarmony, had been proven/revealed as an incomplete and incorrect model to assess/measure personality of persons.
It is a HOAX, a FRAUD to use the Big Five normative test in year 2019. 


eHarmony was copycatted in several countries like
the online dating sites EliteSingles / SilverSingles in Canada, Australia, USA, UK, Chile, Mexico; eDarling in Spain, German, France, Russia;
also TeAmo in Russia is another copycat of eHarmony;
esync (eSynchrony) in Singapore,
MiMediaManzana in Colombia, Peru, Mexico, Chile, etc.,

and

about article: Does DNA Dating Pass the Genetic Sniff Test?
https://onlinedatingsoundbarrier.blogspot.com/2018/03/about-article-does-dna-dating-pass.html


Pheramor isn’t the first app to prey on people’s scientific ignorance
http://onlinedatingsoundbarrier.blogspot.com.ar/2018/03/pheramor-isnt-first-app-to-prey-on.html

Pheramor DNA-Based Dating Using 'Attraction' Genes Attracts Questions
http://onlinedatingsoundbarrier.blogspot.com.ar/2018/02/pheramor-dna-based-dating-using.html


Genetic Matchmaking is mainly  based on the T_shirt Experiment that only proved:
normally cycling women (not pregnant and not taking contraceptive pills) are (temporarily) attracted by the perspiration scent of clothes used by men with a Major Histocompatibility Complex MHC more dissimilar to theirs,

and not proved: women attracted by those men for long term mating with commitment.
and
2 Scientific Papers debunk their claims.
1) "Human oestrus" Gangestad & Thornhill (2008)
"Only short-term but not long-term partner preferences tend to vary with the menstrual cycle"
http://onlinedatingsoundbarrier.blogspot.com.ar/2017/12/about-article-pheramor-at-gizmodo.html
2) "Does the contraceptive pill alter mate choice in humans?" Alvergne & Lummaa (2009)
".. whereas normally cycling women express a preference for MHC (Major Histocompatibility Complex) dissimilarity in mates, pill users prefer odours of MHC-SIMILAR men, indicating that pill use might eliminate adaptive preferences for genetic dissimilarity."
................
"...., Roberts et al. attempted to eliminate these potential confounds by adopting a within-subject design in which women's mate preferences were assessed before and after they began taking the pill. Women starting the pill showed a significant preference shift towards MHC SIMILARITY compared with three months before the pill was taken, a shift that was not observed in the control group of normally cycling women."
http://onlinedatingsoundbarrier.blogspot.com.ar/2017/09/dnaromance-introduces-chemistry-to.html
Please remember personality = temperament + character
Personality is composed of two basic types of traits:
traits that an individual acquires, dimensions of character;
and
traits with biological underpinnings, dimensions of temperament (Cloninger 1987)


At the paper  "Perceptions of Ideal and Former Partners' Personality and Similarity
The authors had written
".... mismatches in personality are a frequently mentioned cause for relationship break-up. If former partners indeed have dissimilar personalities, our findings underline how difficult it is for many people to select a mate with a similar personality, or, alternatively, how little value individuals put on finding a similar partner in terms of personality.
The present study's results, as well as the results found in previous studies (e.g., Eastwick & Finkel, 2008), may be used to educate people, especially singles, about what really matters in long-term relationships, for instance, similarity in personality, instead of complementarity."
  


Compatibility is all about a high level on personality similarity between prospective mates for long term mating with commitment, and not meet other people with similar interests or political views.
