B32 "Is it a date? How payment affects perceptions of romantic interest"
This study examined the effect of financial payment on perceptions of romantic interest. Results suggest that a meal is more likely to be defined as a date when the man pays fully and that men view partial payment by a man as detrimental to the female partner’s romantic interest.

E46 "Your Torso Can Talk: Visual Cues to Similarity Detection"
People rely on visual cues in the torso area to detect similarity and to translate similarity into attraction. In an experiment, dyads wearing a black garbage bag over their body (head, arms, legs exposed) were less similar (and existing similarity did not lead to attraction) compared to normal, bagless dyads.

PAPER Language Style Matching

Language Style Matching Predicts Relationship Initiation and Stability

(not satisfaction and does not check/assess personality of participants)
Study 1 Method Participants. The analyses reported here included 40 men and 40 women (mean age = 19.6 years, SD = 1.2) who volunteered to take part in a speed-dating study.
Study 2 Method Participants. Eighty-six couples (mean age = 19.0 years, SD = 1.4) On average, the couples had been dating approximately 1.31 years (SD = 1.06).
(They were all too young persons)

The Language Style Matching (LSM) does not measure the kind of vocabulary two persons use, but how similarly they employ function-words, which include pronouns, prepositions, articles, conjunctions, auxiliary verbs, and a small group of similar words that have virtually no meaning on their own.

It is consistent with "You and your friends have very similar minds / FACEBOOK research"

An engine based on Language Style Matching will add a lot of ..... DISTORTION!

Profiling by music preferences to assess personality
video preferences to assess personality
color preferences to assess personality
bookmarks preferences to assess personality
handwriting analysis to assess personality
purchases and buying trends from credit cards to assess personality
and other methods like them
add distortion to the measurement.

Latest Research in Theories of Romantic Relationships Development clearly shows: compatibility is all about a high level on personality similarity between prospective mates for long term mating with commitment.

*Similarity is a word that has different meanings for different persons or companies, it exactly depends on how mathematically is defined.

Two papers debunking speeddating for serious dating

Two NEW & FRESH papers debunking speeddating for serious dating (also a big punch to Behavioural recommender systems like IntroAnalytics, VisualDNA, the one used at PlentyOfFish or other system that learns your preferences)

"Why Mate Choices are not as Reciprocal as we Assume: The Role of Personality, Flirting and Physical Attractiveness" (2010)
..... Lars Penke, ....

Results show that actual mate choices are not reciprocal although people strongly expect their choices to be reciprocated and flirting behaviour is indeed strongly reciprocal. This interesting pattern of results was explained by investigating individual and dyadic effects of flirting, self-perceived mate value and physical attractiveness on mate choices. Results have important implications for understanding mating behaviour, sex differences and the (in)accuracies of mating decisions.

"From Dating to Mating and Relating: Predictors of Initial and Long-Term Outcomes of Speed-Dating in a Community Sample" (2010)
..... Lars Penke, ....

We studied initial and long-term outcomes of speed-dating over a period of 1 year in a community sample involving 382 German participants aged 18–54 years. They were followed from their initial choices of dating partners up to later mating (sexual intercourse) and relating (romantic relationship). Using Social Relations Model analyses, we examined evolutionarily informed hypotheses on both individual and dyadic effects of participants' physical characteristics, personality with Five Factor Model (FFM), education and income on their dating, mating and relating.
The online questionnaire assessed demographic details, health status, stable personality traits and relationship and sexual history including questions about women's contraception usage and menstrual cycle.
Both men and women based their choices mainly on the dating partners' physical attractiveness, and women additionally on men's sociosexuality, openness to experience, shyness, education and income. Choosiness increased with age in men, decreased with age in women and was positively related to popularity among the other sex, but mainly for men.
Partner similarity had only weak effects on (speed)dating success. The chance for mating with a speed-dating partner was 6%, and was increased by men's short-term mating interest; the chance for relating was 4%, and was increased by women's long-term mating interest.
Another way of looking at the probabilities of 6% and 4% is to convert them into time and money spent on multiple speeddating events, assuming independence of the outcomes of each event. Assuming that one has to pay 30 Euros for a speed-dating event lasting 3 hours including everything, finding a relationship partner requires investing 75 hours and 750 Euros on average.
Also confirmed was our expectation that similarity of the dating partners facilitates reciprocated choices. However, after controlling for individual effects the similarity effect was only significant for facial attractiveness. Kurzban and Weeden (2005) found similarity effects for height and BMI, whereas Luo and Zhang (2009) did not find any significant effect for 44 tests of similarity. Together, these findings suggest that similarity effects are weak in studies of brief real dating interactions. This result is different from the conclusions from questionnaire studies of attraction to hypothetical partners, from dyadic interaction studies where similarity effects are confounded with individual effects, and from studies of similarity in couples that regularly find clear similarity effects even after controlling for individual effects (Klohnen & Luo, 2003). It seems that similarity effects need more time to emerge than the 3 minutes provided by speed-dating.

Finally, our expectation that women's mating is predicted by the short-term mating preferences of their male matches, whereas men's relating is predicted by the long-term preferences by their female matches was confirmed both 6 weeks and 1 year after speeddating.

[Remember: People often report partner preferences that are not compatible with their choices in real life. uncovered by Eastwick & Finkel (2008); Kurzban & Weeden (2005-2007); Alison P. Lenton,  Lars Penke, Peter M. Todd and Barbara Fasolo (2007)]

C253 "It's that time of the month: The effects of hormonal shifts on female mate value, depressive symptomology, and short term mating orientation."

Heather Adams, MA, and Victor Luévano, PhD
California State University Stanislaus

It is consistent with
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.

PERSOC: A Unified Framework for Understanding the Dynamic Interplay of Personality and Social Relationships

PERSOC is an international network of researchers interested in the fascinating interplay of personality and social relationships.

It will be useless at all, see why at The next generation of matching algorithms

eHarmony / eHarmonyLabs does not promote own papers

Why eHarmony / eHarmonyLabs does not promote the papers published by its brains?

"Assortative mating, convergence, and satisfaction in married couples"


Article first published online: 8 NOV 2010 DOI: 10.1111/j.1475-6811.2010.01309.x

"This work investigates assortative mating and convergence in personality and their effect on marital satisfaction. Measures of personality were collected from a sample of married couples before they met and twice after they were married. Results showed evidence for assortative mating but not for convergence in an average couple. Similarity and convergence in personality predicted later marital satisfaction. These results indicate that similarity and convergence in psychological characteristics may benefit relationships and that while spouses may choose partners with similar personalities they do not become more like their partners in the early part of their marriage."

B13 "Similarity predicts relationship satisfaction in Brazil"
Erina Lee1, Gian C. Gonzaga1,2; 1eHarmony Labs, 2University of California, Los Angeles
Two studies investigated the impact of similarity on relationship satisfaction in Brazil.
In study 1, couples' independent ratings of similarity across personality, values, and interests predicted satisfaction.
In study 2, perceived similarity in personality and interests (coded from open-ended text) predicted satisfaction.
Results support the importance of similarity in relationships.

Surely because eHarmony's Management Team knows eHarmony's personality similarity approach is correct, but how eHarmony assesses personality and how eHarmony calculates similarity is incorrect.

ZOOSK is not a Scientific Matchmaking Service/System.

Online Dating site, ZOOSK is not a Scientific Matchmaking Service/System.
That method is only a HOAX!

Definition of SCIENTIFIC
: done in an organized way that agrees with the methods and principles of science.

Definition of SCIENCE
: an activity that is done by using methods that are known to produce particular results.
: knowledge or a system of knowledge covering general truths or the operation of general laws especially as obtained and tested through scientific method.

No actual online dating site can prove its matching algorithm can match prospective partners who will have more stable and satisfying relationships 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.

South America is an unserved / unexploited market.

Many South American online dating proposals claim "millions of members" in their databases
see how Alexa shows that claim can not be true.
