DIFFERENT PERSONALITY TESTS FOR ON LINE DATING
&
MORE POWER CALCULATION FOR COMPATIBILITY MATCHING.

Case 1)
Many dating sites are using an adapted Myers-Briggs Type Indicator (MBTI) test.
MBTI is a psychological test designed to assist a person in identifying their personality preferences. It has four BIPOLAR independent variables:
Extraverted (E) or Introverted (I)
Sensing (S) or Intuitive (N)
Thinking (T) or Feeling (F)
Judging (J) or Perceiving (P)
The different possibilities are 2*2*2*2 == 16 (personality types), they name:
ISTJ - The Duty Fulfillers // ESTJ - The Guardians // ISFJ - The Nurturers // ESFJ - The Caregivers // ISTP - The Mechanics // ESTP - The Doers // ESFP - The Performers // ISFP - The Artists // ENTJ - The Executives // INTJ - The Scientists // ENTP - The Visionaries // INTP - The Thinkers // ENFJ - The Givers // INFJ - The Protectors // ENFP - The Inspirers // INFP - The Idealists

Test Result looks like this:

Personality type results: ESTJ

EI: 7 out of 17
Extrovert |-------------------------------------------------| Introvert
...............................|
..............................41%
SN: 8 out of 17
Sensation |-------------------------------------------------| iNtuition
....................................|
...................................47%
TF: 5 out of 17
Thinking |-------------------------------------------------| Feeling
........................|
.......................29%
JP: 5 out of 17
Judging |-------------------------------------------------| Perceiving
........................|
.......................29%

As only 16 personality types are rather few, dating sites upgrade the model using photos, likes and dislikes formulary, etc.

Case 2)
Other dating sites use PROPRIETARY tests or models:

With 10 degrees per independent variable at the results of the test (1,2,3,4,5,6,7,8,9,10):
If only 5 variables are used, like a 5 Traits Inventory, Big-5 dimensions of personality: Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness; the Ensemble (the whole set of different possibilities) is 10*10*10*10*10 == 1 * 10^5 == 100,000 different possibilities (personality types). This is only the whole set of different personality possibilities, the way to compare one to others is a another matter.

With 10 degrees per independent variable at the results of the test (1,2,3,4,5,6,7,8,9,10)
If only 7 variables are used, Big-7 dimensions of personality: Neuroticism, Extraversion,
Openness, Agreeableness, Conscientiousness, Self-Esteem and Self-Doubt; the Ensemble (the whole set of different possibilities) is 10*10*10*10*10*10*10 == 1 * 10^7 == 10,000,000 different possibilities (personality types).

With 3 degrees per independent variable (Mostly agree / Nor agree nor disagree / Mostly disagree), at the results of the test; NOT at the questionnaire.

If only 12 variables are used the Ensemble (the whole set of different possibilities) is
3*3*3*3*3*3*3*3*3*3*3*3 == 1 * 3^12 == 531,441 == 5.3 * 10^5 different possibilities (personality types). This is only the whole set of different personality possibilities, the way to compare one to others is a another matter.

If 16 variables are used the Ensemble is
3*3*3*3*3*3*3*3*3*3*3*3*3*3*3*3 == 1 * 3^16 == 43,046,721 == 4.3 * 10^7 different possibilities

With 5 degrees per independent variable at the results of the test (Highly agree / Mostly agree / Nor agree nor disagree / Mostly disagree / Highly disagree)

If only 12 variables are used the Ensemble is
5*5*5*5*5*5*5*5*5*5*5*5 == 1 * 5^12 == 244,140,625 == 2.4 * 10^8 different possibilities

If 16 variables are used the Ensemble is
5*5*5*5*5*5*5*5*5*5*5*5*5*5*5*5== 1 * 5^16 == 152,587,890,625 == 1.5 * 10^11 different possibilities
More than World Population (WP): nearly 6,400 millions persons == 6.4 * 10^9

Although the validity & reliability of the proprietary tests could be high, i.e. >80%, the main problem / endeavour appears in how to compare and assign compatibility.

A FREE test named IPIP-NEO can be taken at:
http://www.personal.psu.edu/faculty/j/5/j5j/IPIP/

http://ipip.ori.org/
Five broad domains of personality, followed by a more detailed description of personality according to the six subdomains that comprise each domain.

Case 3)
Using a complete 16 Personality Factors model, 16PF test, the Ensemble ( the whole set of different possibilities) is 10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10 == 1 * 10^16 == 10,000,000,000,000,000 of different possibilities (personality types), thus each person is really unique. This is only the whole set of different personality possibilities, the way to compare one to others is a another matter.
The output of the personality test is like this A:05, B:09, C:06, E:06, F:08, G:04, H:07, I:05, L:03, M:06, N:04, O:06, Q1:08, Q2:02, Q3:05, Q4:04.
(A) Warmth, (B) Reasoning, (C) Emotional Stability, (E) Dominance, (F) Liveliness, (G) Rule-Consciousness, (H) Social Boldness, (I) Sensitivity, (L) Vigilance, (M) Abstractedness, (N) Privateness, (O) Apprehension, (Q1) Openness to Change, (Q2) Self-Reliance, (Q3) Perfectionism and (Q4) Tension

World Population (WP): nearly 6,400 millions persons == 6.4 * 10^9
16PF`s Ensemble== E == 1 * 10^16
WP / E == (6.4 * 10^9) / (1 * 10^16) == 6.4 * 10^-7 == 64 * 10^-6
i.e. WP is 64 micro part of E!!!

If the comparison / matching algorithm “compares” each personality test’s result with the others, for a DataBase with an initial charge of N clients will need [ N * (N-1) ] / 2 comparisons.
For 100,000 clients needs nearly 5,000,000,000 of comparisons.
For 1,000,000 clients needs nearly 500,000,000,000 of comparisons

It is really a hard work, requires time and power calculation!!!

For the Dating Industry, the main problem to solve IS NOT to design personality tests for dating.
The main problem to solve IS TO invent a precise way / method to COMPARE the results of the tests between each others.

The next generation of serious dating and matchmaking will be more scientific than ever.

2005: The Flight to Quality process started.

By 2008: Quality Norms ISO 9001:2000 & Legislation will be expected. The market will divide into two well-identified groups.

*13-25 years old persons (teenagers) not interested in serious dating; they will use the service for fun. They will need exclusive CONTENTS for them. They will also play "people matching people game"; although there is a hierarchy between human relationships where feelings are involved; and could be very dangerous and harmful like a "big liquidizer".

*26-and more years old persons interested in serious dating. They will need quality CONTACTS (compatible real persons), Special Services (professionalism): the next generation of dating and matchmaking will be more scientific than ever, most probably the 16PF5 test in different languages (or similar test) will be a "must have" in compatibility matching. This group will not allow their friends / mums / parents / neighbours / relatives or "interested third parties" to be involved in a private matter as building a personal relationship with future in mind; a process that only concerns two persons.
These clients will have a good reason to pay for the service: avoid being hurt in their feelings by other persons.

Actually, many people try to "improve" their profile, to "retouch" photos and to "exaggerate" when filling likes and dislikes formularies in order to "sell better" their profile. People trend to overstate their qualities, they do not say the exact truth. They can and they will lie and also if the membership is FREE they can appear several times with several profiles.
Lucky, a personality test like 16PF5 works as an independent evaluation of a person; an external point of view.

I noticed that many users / subscribers (to sites that use proprietary tests or models) complaint about an actual big problem in "scientific dating and matchmaking": lack of precision / low precision / low successful matching rates. As far as I could analyze, it seems that proprietary tests or models have great precision in measuring different psychological variables but the matching algorithm has low precision when comparing one psycho-pattern to others.
It could be a great improvement if any dating site that uses "scientific dating and matchmaking"; i.e. applying psycho-test to measure personality items; specifies its ENSEMBLE (the whole set of different valid possibilities) and a figure per each comparison between persons, like: client#01 to client#02 == 74.79865772%
and not a poor bar-graphic or a series of 5 empty / half / full-filled hearts-icon.

Couple Similarity and Marital Quality

Our study presents one of the most comprehensive examinations of the similarity–satisfaction link. The observed similarity–satisfaction correlations suggest that similarity on personality related domains was strongly associated with satisfaction, whereas similarity on attitude-related domains was not. This is an intriguing pattern of findings when considered in conjunction with the just reviewed assortative mating results: Spouses showed substantial similarity on attitude-related domains, but this similarity does not appear to be related to satisfaction; spouses were no more similar than randomly paired couples on personality-related domains, but this similarity appears to be important to satisfaction.
.................
People may be attracted to those who have similar attitudes, values, and beliefs and even marry them (at least in part) on the basis of this similarity. However, once individuals are in a committed relationship, it may be primarily personality similarity that influences marital happiness. This suggests that attitude and value similarity may play a different role in relationship development than personality similarity does. For example, whereas similarity in attitudes and values appears to be important early on in the relationship and may play an important role in relationship progression, personality similarity becomes more important as the relationship reaches greater commitment. Our empirical findings and this proposition are certainly consistent with “filter” or “process” theories of relationship development (e.g., Kerckhoff & Davis, 1962; Murstein, 1980) that hold that patterns of similarity and complementarity on different individual-difference domains play differential roles at different points in the relationship development process.
As discussed above, there are several reasons (visibility, salience, and psychological reward value) why similarity in terms of attitudes and values may influence individuals’ partner choices early in the relationship. However, given the substantial variances in value and attitude similarity we observed, it appears that not everybody is paired with a spouse who holds similar attitudes and values. Because of the visibility and saliency of attitudes and values, it is very likely that partners who are not similar on these domains are nevertheless aware of these differences from the outset and yet chose to marry each other anyway. It thus appears likely that attitudinal and value differences, when they exist, are part of a conscious decision to stay together on the basis of other
important considerations. Personality-related characteristics, on the other hand, take much longer to be known and to be accurately perceived. Thus, they are not likely to play a more substantial role until later in the relationship development process. However, once individuals are in a committed relationship, it is difficult to ignore personality differences, because being in a committed relationship entails regular interaction and requires extensive coordination in dealing with the tasks, issues, and problems of daily living.
Whereas personality similarity is likely to facilitate this process, personality differences may result in more friction and conflict in daily life. We currently do not have the data to examine these ideas; however, because of the importance of these issues to marital success and failure, future research designed to better understand these underlying processes is needed.
