   That cartoon is not a joke.
   It is a serious denounce about the state of the Online Dating Proposals for Serious Daters.

   The entire Online Dating Industry for serious daters in 1st World Countries, is a big hoax.

   Since the beggining of 2003, I had been testing online dating sites who offer a compatibility matching method to their daters by creating dummy Male/Female profiles and using them as test points for reverse engineering purposes.

   All the algorithms used by eHarmony, True, Chemistry, PerfectMatch, Be2, Meetic, PlentyOfFish Chemistry Predictor, Parship, RewardingLove, MyType, etc. are like placebo, because they will show, to any member, 3 or 4 persons as highly compatible per 1,000 persons screened, so in a 10,000,000 persons database, any member will see 30,000 to 40,000 members as highly compatible; 30,000 persons is the population of an average small city. ["Lois: This is like the phone directory for a small town! Jan: The town of LoserVille."] Any person can achieve 3 or 4 persons as highly compatible per 1,000 persons screened, searching by his/her own or by mutual filtering methods.

   Success Rates of those sites are less than 10%. The majority of their members are not going to achieve a long term relationship with commitment (or marriage).

   I had discovered “the online dating sound barrier”. Breaking “the online dating sound barrier” is to achieve far better precision than searching on one’s own or mutual filtering.

   No actual online dating site offering a compatibility matching method has published any Scientifc Paper peer reviewed by Academics from different Universities (public scrutiny of findings) showing 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.

   And they are not going to publish any Scientifc Paper peer reviewed by Academics from different Universities because they cannot 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.

   Matching based on Self-Reported Data / Bidirectional Recommendation Engines (Collaborative Filtering) will always be in the range of 3 or 4 persons “recommended” per 1,000 persons screened, in exactly the same range of searching on one’s own.
   and
   Compatibility Matching Algorithms used by actual online dating sites (with Big-5 Model or a proprietary model like the ones used by Perfectmatch or Chemistry), are in the range of 3 or 4 persons “highly compatible” per 1,000 persons screened, in exactly the same range of searching on one’s own. They are using simplified versions of personality traits, instead of the 16PF5 or similar with the complete inventory (16 variables) and inadequate quantitative methods to calculate compatibility between prospective mates, like eHarmony which uses Dyadic Adjustment Scale or other sites which use multivariate linear / logistic regression equations o other powerless equations.

   Actual Online Dating Sites == searching on one’s own == mutual filtering / bidirectional recommendation engines == compatibility matching algorithms, they are all in the same range.

   Breaking “the online dating sound barrier” is to achieve at least:
   3 most compatible persons in a 100,000 persons database.
   12 most compatible persons in a 1,000,000 persons database.
   48 most compatible persons in a 10,000,000 persons database.

   The only way to achieve that is:
   - using the 16PF5 normative personality test, available in different languages to assess personality of members, or a propietary test with exactly the same traits of the 16PF5. The ensemble of the 16PF5 is: 10E16, big number as All World Population is nearly 6.7 * 10E9
   (WorldWide, there are over 5,000 -five thousand- online dating sites, but no one is using the 16PF5)

   - expressing compatibility with eight decimals, like The pattern 6.7.6.8.9.6.7.7.8.7.2.5.8.7.3.4 is 92.55033557% +/- 0.00000001% similar to the pattern 7.7.6.8.8.7.6.5.8.7.4.5.7.7.3.4
   Using a quantized pattern comparison method (part of pattern recognition by cross-correlation) to calculate similarity between prospective mates.

   That sounds about right.

   Anonidate.com is like that too.

   Everyone within walking distance is a worthless homosexual drug addict with two significant others.

   Okcupid looks pretty, but no one wants to meet anyone because of the fake profiles.
