In a previous post I has written about "Two papers debunking speeddating for serious dating"
"Why Mate Choices are not as Reciprocal as we Assume: The Role of Personality, Flirting and Physical Attractiveness" (2010)
"From Dating to Mating and Relating: Predictors of Initial and Long-Term Outcomes of Speed-Dating in a Community Sample" (2010)
Dr. Paul Eastwick had written 2 fresh interesting papers:
"Perceived, not actual, similarity predicts initial attraction in a live romantic context: Evidence from the speed-dating paradigm"
The "similarity-attraction" effect stands as one of the most well-known findings in social psychology. However, some research contends that perceived but not actual similarity influences attraction. The current study is the first to examine the effects of actual and perceived similarity simultaneously during a face-to-face initial romantic encounter. Participants attending a speed-dating event interacted with ∼12 members of the opposite sex for 4 min each. Actual and perceived similarity for each pair were calculated from questionnaire responses assessed before the event and after each date. Data revealed that perceived, but not actual, similarity significantly predicted romantic liking in this speed-dating context. Furthermore, perceived similarity was a far weaker predictor of attraction when assessed using specific traits rather than generally.
"Do Ideal Partner Preferences Predict Divorce? A Tale of Two Metrics"
Though people report idiosyncratic desires for particular traits in an ideal romantic partner, few studies have examined whether these ideals predict important long-term relationship outcomes. The present 3.5-year longitudinal study of newlywed couples used survival analysis to investigate whether the match between participants' ideal preferences and the traits they perceive in their partner predict the likelihood of divorce. Results depended entirely on whether the match was conceptualized as a match in level (e.g., high ideal preference for a trait with the presence of the trait in the partner) or in pattern (e.g., the within-person correlation of ideals with a partner's traits across all traits). The match between the pattern of ideals and traits negatively predicted divorce with an effect size larger than most established divorce risk factors. However, the match in level was unrelated to divorce, suggesting that perspectives emphasizing ideals for the level of traits may encounter predictive validity problems.
In the paper "Perceptions of Ideal and Former Partners' Personality and Similarity" Pieternel Dijkstra / Dick P. H. Barelds / University of Groningen, The Netherlands
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."
In case you had not understood the above, those papers are big punches to ......... Behavioural recommender systems or other system that learns your preferences.
The 3 milestone discoveries of the 2001 - 2010 decade for Theories of Romantic Relationships Development are:
I) Several studies showing contraceptive pills users make different mate choices, on average, compared to non-users. "Only short-term but not long-term partner preferences tend to vary with the menstrual cycle"
II) People often report partner preferences that are not compatible with their choices in real life. (Behavioural recommender systems or other system that learns your preferences are useless)
III) What is important in attracting people to one another may not be important in making couples happy. Compatibility is all about a high level on personality similarity between prospective mates for long term mating with commitment.
WorldWide, there are over 5,000 -five thousand- online dating sites
but no one is using the 16PF5 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!
but no one is scientifically proven!
Without offering the NORMATIVE16PF5 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry.
Since several years ago, I had been hammering your head, drilling your brain with the personality similarity concept. Please notice I will continue with this policy for the next 10 years, until 2022 if necessary.
