The 2001 - 2010 decade will end soon.
Only 3 major discoveries can help to revolutionize the online dating industry.
Major online dating sites can not ignore them any more, or they will die instead.
I) Several studies showing contraceptive pills users make different mate choices, on average, compared to non-users.
I.1) "Human oestrus" Gangestad & Thornhill (2008)
"Only short-term but not long-term partner preferences tend to vary with the menstrual cycle"
I.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."
I.3) "Personality and reproductive success in a high-fertility human population" Alvergne, Jokelac & Lummaaa (2010)
The reproductive success of both men and women is influenced by our personality traits, according to the paper.
The study, found that women with higher levels of neuroticism and more extravert men, are likely to give birth to a larger number of children in societies with traditionally high birth rates.
II) People often report partner preferences that are not compatible with their choices in real life.
[uncovered by Eastwick & Finkel (2008); Kurzban & Weeden (2007); Todd, Penke, Fasolo, & Lenton (2007)]
II.1) "Do People Know What They Want: A Similar or Complementary Partner?" Barelds & Dijkstra (2008)
II.2) Also reported in "What lies beneath: The linguistic traces of deception in online dating profiles." Toma & Hancock (2010)
That paper investigates whether deceptions in online dating profiles correlate with changes in the way daters write about themselves in the open-ended portion of the profile, and whether those changes are detectable by either computerized linguistic analyses or human judges.
III) The strict personality similarity axis.
Latest Research in Theories of Romantic Relationships Development shows: compatibility is all about a high level on personality* similarity* between prospective mates for long term mating with commitment.
*personality measured with a normative test.
*similarity: there are different ways to calculate similarity, it depends on how mathematically is defined.
Also 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 and they need to calculate personality similarity between them.
The entire Online Dating Industry for serious daters in 1st World Countries has:
* No Legislation.
* No Quality Norms.
* Low reliable background checks.
The entire Online Dating Industry for serious daters in 1st World Countries is a HOAX, performing as a Big Online Casino, with a low effectiveness/efficiency level of their matching algorithms (less than 10%),
There is a range convergence phenomenon between the 3 mains tools online dating sites offer now: Searching by your own, Recommendation Engines and Compatibility Matching Methods based on proprietary models or the Big5. Any member receives on average 3 to 4 prospective mates as selected / recommended / compatible for dating purposes per 1,000 members screened in the database.
They all 3 are performing the same for serious daters, with a high percentage of false positives, like gun machines firing flowers.
The Online Dating Industry needs innovations, but the innovations the Online Dating Industry needs will come from only one source: the latest discoveries in theories of romantic relationships development with commitment.
WorldWide, there are over 5,000 online dating sites
but no one is using the 16PF5 (or similar test) to assess personality of its members.
Without offering the 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.
