NEW paper: Assortative Mating and Personality in Human Couples

"Assortative Mating and Personality in Human Couples: A Study Using Cloninger's Temperament and Character Inventory"


The trend toward assortative mating is the rule in Western societies for a large series of factors. The case for personality variables is however not clear, since weak and even negative relationships have been found in correlation analyses between spouses. The present study compared the profiles of members from 145 stable couples living together for more than 5 years, and representative of the Belgian population. Personality measurements were performed using Cloninger's Temperament and Character Inventory (TCI), in order to: 1) determine whether the subject's TCI predicts the partner's profile; 2) determine whether modeling has an important influence between the partners; 3) describe the behavior of personalities with extreme traits; 4) measure whether personalities with extreme traits would favor complementarity over homogamy. In all dimensions but Harm Avoidance and its sub-dimensions, positive associations were found between the partners, indicating a trend toward assortative mating. These differences were significant for Novelty Seeking, Reward Dependence, Persistence and Cooperativeness. Trends were observed in Self-Directedness and Self-Transcendence. Subjects with extreme personality traits were not shown to favor complementarity over assortative mating. Homogamy was thus confirmed here for a series of personality traits, independently of the TCI Temperament or Character classification and on the subjects position in the distribution.

Please remember personality = temperament + character
Personality is composed of two basic types of traits:
traits that an individual acquires, dimensions of character;
traits with biological underpinnings, dimensions of temperament (Cloninger 1987).

Please also see the German paper: "Only the congruent survive - Personality similarities in couples. Personality and Individual Differences" and "Perceptions of Ideal and Former Partners' Personality and Similarity" where the authors has written:
"Our findings strongly support the 'similarity-attraction' hypothesis: Individuals clearly desire a potential partner with a similar personality.
In addition to finding a mate with a similar personality, our study showed that individuals seek a mate who is slightly 'better' than they are: They prefer a mate who is somewhat less neurotic, more agreeable, more conscientious, more open and more extraverted than they are themselves.
.... 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."

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.
*Although no actual fresh paper uses the 16PF normative personality test (they mostly use different versions of the normative Big5 personality test instead) and linear or logistic multivariate regression equations to calculate similarity, they clearly show a connection between personality similarity and marital happiness / dyadic success (stability and satisfaction) for some persons.
**Similarity is a word that has different meanings for different persons or companies, it exactly depends on how mathematically is defined.

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!
but no one is scientifically proven! The only way to revolutionize the Online Dating Industry is using the 16PF5 normative personality test, available in different languages to assess personality of members, or a proprietary test with exactly the same traits of the 16PF5 and expressing compatibility with eight decimals (needs a quantized pattern comparison method, part of pattern recognition by cross-correlation, to calculate similarity between prospective mates.)
High precision in matching algorithms is precisely the key to open the door and leave the infancy of compatibility testing.
It is all about achieving the eighth decimal!
With 8 decimals, you have more precision than any person could achieve by searching on one's own, but the only way to achieve the eighth decimal is using analysis and correlation with quantized patterns.

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 All other proposals are NOISE and perform as placebo.

What comes after Social Networking?
My bet: The Next Big Investment Opportunity on the Internet will be …. Personalization!
Personality Based Recommender Systems and Strict Personality Based Compatibility Matching Engines for serious Online Dating with the normative 16PF5 personality test.
