ANOTHER HOAX "Pheromone Parties"

ANOTHER HOAX "Pheromone Parties"
On "Pheromone Parties" People Are Matched By Dirty T-shirts

They now offer the same as Basisnote, GenePartner, ScientificMatch and other proposals offering DNA matching which are only 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"

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)


The key to long-lasting romance is STRICT PERSONALITY SIMILARITY
-------------------------------------------------
ScientificMatch, Basisnote, Genepartner (LittleHint) y los que ofrecen DNA matching, son un fraude porque están basados en el experimento de la remera sudada (T-shirt experiment) donde un grupo de mujeres calificaban olores a sudor de varones como atractivos, neutros o repulsivos. En algunos casos las mujeres se sentían atraídas por el olor a sudor de un varón que tuviera un Complejo Principal de Histocompatibilidad (MHC) lo más diferente al de ellas (no atraídas por el varón, sino por el olor a sudor del varón impregnado en una camiseta) Fue refutado por Alvergne & Lummaa en "Does the contraceptive pill alter mate choice in humans?" 2009 Las mujeres que tienen sus períodos en forma normal presentan preferencias de selección de pareja de corto (en la fase ovulatoria) y largo plazo; mientras que las mujeres que usan tratamientos anticonceptivos hormonales (que simulan la concentración de hormonas del embarazo), anulan su preferencia de selección de pareja de corto plazo, buscan pareja estable, eligen compañeros similares a ellas en MHC
