Remember:
IPSATIVE personality tests are OBSOLETE (self-descriptive questionnaires) and should be discarded, not to use in online dating sites like: MBTI (PerfectMatch), DISC (ThomasKnowsPeople), Enneagram (Dopasowani) or other proprietary ipsative tests like the ones used at Chemistry, ButterfliesAgain, Doskonalapara, PembePanjur, LittleHint, oneGoodLove and others.
I had reviewed over 55 compatibility matching engines intended for serious dating since 2003, when I had discovered "the online dating sound barrier" problem.
NORMATIVE personality tests like BIG5 versions used at PlentyOfFish, True, eHarmony/TeAmo, MeeticAffinity, Parship, Be2, and others; are good for guidance (orientation) purposes but not good enough for predictive purposes.
"Because the BIG5 groups the more specific primary-level factors, feedback organized around the five Global Factor scales is more easily understood. For detailed feedback or predictive purposes, one should assess the more specific primary factors. Research has shown that more specific factors like the primary scales of the 16PF Questionnaire predict actual behavior better than the BIG5 Global Factors. For example, one extravert (a bold, fearless, high-energy type) may differ considerably from another (a sweet, warm, sensitive type), depending on the extraversion-related primary scale score patterns, so deeper analysis is typically warranted." Extracted from the 16PF5 Manual
The BIG5 normative personality test is and OVERSIMPLIFICATION.
o·ver·sim·pli·fy (vr-smpl-f)
v. o·ver·sim·pli·fied, o·ver·sim·pli·fy·ing, o·ver·sim·pli·fies
v.tr.
To simplify to the point of causing misrepresentation, misconception, or error.
v.intr.
To cause distortion or error by extreme simplification of a subject.
Online Dating sites have very big databases, in the range of 20,000,000 (twenty million) profiles, so the BIG5 model is not enough for predictive purposes.
eHarmony is the OLDEST site in the Online Dating Industry using the BIG5 test.
eHarmony is a 13+ years old obsolete site, a HOAX, based on a Big Scientific Fraud.
The ENSEMBLE of the BIG5 model is 100,000. If you suppose a normal distribution of personality in a 20,000,000 (twenty million) database of persons, 200 or more persons will be seen as THE SAME, i.e:
20,000,000/100,000 = 200 All Database is 200 times bigger than the ensemble.
Over 60,000 persons will be seen as NEARLY the SAME. Only 0.3% of the database.
Do you remember when eHarmony Japan disclosed "99.7% of eHarmony’s members will not be introduced to you (translated from the failed Japanese site)", i.e. only 0.3% of members will be shown as a compatible partner for you; that is the power of eHarmony's matching algorithm (the effectiveness/efficiency of the matching algorithm.)
0.3% means: 3 persons per 1,000 persons screened in the same range as searching by your own! eHarmony's matching algorithm performs really as placebo.
That explanation shows you why any online dating site using the BIG5 model has a whole precision in the same range or less than you could achieve searching by your own!!!
Now it seems, some Psychologists had understood that mistake, to use the BIG5 normative personality test for online dating purposes and began to encourage the use of other tests,
like
California Psychological Inventory (CPI)
and
The Millon Index of Personality Styles-Revised (MIPS Revised)
but my best recommendation is, of course, the 16PF5 normative personality test.
Nor the CPI nor the MIPS can outperform the 16PF5.
The Online Dating Industry does not need a 10% improvement, a 50% improvement or a 100% improvement. It does need "a 100 times better improvement"
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.
100 times better than Compatibility Matching Algorithms used by actual online dating sites!
The only way to achieve that is:
- using the 16PF5 normative personality test, available in different languages to assess personality of members, or a proprietary test with exactly the same traits of the 16PF5. The ensemble of the 16PF5 is: 10E16, big number as All World Population is nearly 7.0 * 10E9 (estimated OCT 2013)
- 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.
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!
The only way to revolutionize the Online Dating Industry is using the 16PF5 normative personality test, available in different languages to assess personality of members, or a proprietary test with exactly the same traits of the 16PF5 and expressing compatibility with eight decimals (needs a quantized pattern comparison method, part of pattern recognition by cross-correlation, to calculate similarity between prospective mates.)
High precision in matching algorithms is precisely the key to open the door and leave the infancy of compatibility testing.
It is all about achieving the eighth decimal!
With 8 decimals, you have more precision than any person could achieve by searching on one's own, but the only way to achieve the eighth decimal is using analysis and correlation with quantized patterns.
Without offering the NORMATIVE16PF5 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry All other proposals are NOISE and perform as placebo.
