eHarmony USA patched the Questionnaire? 3

In previous posts I had written about patches at eHarmony's Questionnaire in Attitudes and Opinions.
It seems to be an adaptive questionnaire it appears when you nearly finish the last question of the "original & old" questionnaire.

eHarmony USA patched the Questionnaire. 2

Last March eHarmony received a "major" redesign and included the Questions feature.

eHarmony is nearly a 12 years old & obsolete site, and a HOAX with any scientific proof.

I had challenged eHarmony's Team, several times,  to replace eHarmony, a 12 years old & obsolete site, performing as placebo, with a a new site with a new matching algorithm using the 16PF5 test or similar including the 3 latest discoveries in theories of romantic relationships development with commitment.
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.
Also there is a similarity trilogy between genetic, mate choice and personality based recommender systems.
But .... eHarmony's Team don't want to innovate in nothing!

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!


  1. Estimado Fernando: Quizás Usted sepa que soy el titular del sitio El cual promueve vínculos, pero no lo hacemos on-line todavía. En lo personal me interesa su trabajo y me gustaría que me indicara dónde puedo leer más acerca de su algoritmo de compatibilidad y sus bases científicas.
