Pheramor DNA-Based Dating Using 'Attraction' Genes Attracts Questions
http://onlinedatingsoundbarrier.blogspot.com.ar/2018/02/pheramor-dna-based-dating-using.html

 Genetic Matchmaking is mainly  based on the T_shirt Experiment that only proved:
normally cycling women (not pregnant and not taking contraceptive pills) are (temporarily) attracted by the perspiration scent of clothes used by men with a Major Histocompatibility Complex MHC more dissimilar to theirs,
and not proved: women attracted by those men for long term mating with commitment.
and
2 Scientific Papers debunk their claims.
1) "Human oestrus" Gangestad & Thornhill (2008)
"Only short-term but not long-term partner preferences tend to vary with the menstrual cycle"
http://onlinedatingsoundbarrier.blogspot.com.ar/2017/12/about-article-pheramor-at-gizmodo.html
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."
................
"...., Roberts et al. attempted to eliminate these potential confounds by adopting a within-subject design in which women's mate preferences were assessed before and after they began taking the pill. Women starting the pill showed a significant preference shift towards MHC SIMILARITY compared with three months before the pill was taken, a shift that was not observed in the control group of normally cycling women."

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

At the paper  "Perceptions of Ideal and Former Partners' Personality and Similarity" 
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."   


 

genetic matchmaking? 23andMe launches first TV ad campaign

Just read the article at Vator "23andMe launches first TV ad campaign"

Unfortunately the information provided from 23andMe (DNA Analysis) is so vague, so imprecise that is only suitable for entertainment/educational purposes than to take it seriously (to change your lifestyle).

The reports are like

Heart Attack:
- You:
2.4 out of 100 men of European ethnicity who share your genotype will get Heart Attack between the ages of 40 and 49.
3.8 out of 100 men of European ethnicity who share your genotype will get Heart Attack between the ages of 50 and 59.
5.3 out of 100 men of European ethnicity who share your genotype will get Heart Attack between the ages of 60 and 69.
11.0 out of 100 men of European ethnicity who share your genotype will get Heart Attack between the ages of 70 and 79.
20.9 out of 100 men of European ethnicity who share your genotype will get Heart Attack between the ages of 40 and 79.


- Average:
2.4 out of 100 men of European ethnicity will get Heart Attack between the ages of 40 and 49.
3.9 out of 100 men of European ethnicity will get Heart Attack between the ages of 50 and 59.
5.4 out of 100 men of European ethnicity will get Heart Attack between the ages of 60 and 69.
11.1 out of 100 men of European ethnicity will get Heart Attack between the ages of 70 and 79.
21.2 out of 100 men of European ethnicity will get Heart Attack between the ages of 40 and 79.

-------------
Please remember, 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.

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)]
(Behavioural recommender systems or other system that learns your preferences are useless)


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.

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!
