NEW FRESH paper "Personality similarity, perceptual accuracy, and relationship satisfaction in dating and married couples"

For decades, researchers have been striving to identify factors that lead to relationship and marital satisfaction, and the link between personality traits and relationship satisfaction has received much attention. The prediction of marital satisfaction based on personality characteristics of both partners has a long history and previous research has demonstrated the robust relationships between relationship quality, functioning and outcomes, and broad personality traits. A recent meta-analysis of Montoya, Horton, and Kirchner (2008) on the impact of actual and perceived similarity on interpersonal attraction indicated that perceived similarity was a significant predictor of interpersonal attraction. ["Is actual similarity necessary for attraction? A meta-analysis of actual and perceived similarity" Results indicated that the associations between interpersonal attraction and both actual similarity (r = .47) and perceived similarity (r = .39) were significant and large. ] However, in that meta-analysis, relationship satisfaction was considered as a measure of interpersonal attraction and the perceptual and actual personality similarity were not confined to personality traits.


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.
II) People often report partner preferences that are not compatible with their choices in real life. 
III) 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.

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.
