I confess. In 1979 Pete Bentler and I published an article entitled “Simple Minitheories of Love” in the highest prestige journal on personality and social psychology.
Blame it on the exploits of the greatest psychometrician of his generation and a 28 year-old wanna-be psychometrician, both active personality researchers, trying to convince the field that the new statistical modeling methods (Structural Equation Models; LISREL) they were testing would revolutionize the field (I was wrong on that one, too).
Now ask yourself why neither of these guys — nor any of the other main figures in the fields of psychometrics, sociometrics, personality, social psychology, attraction research — ever went on to start a web site to match individuals on the basis of personality and life style questionnaires (I won’t dignify them by calling them tests); such sites became quite lucrative. This was in spite of the fact that at least one (Huba) had the opportunity to do so during the years when he was the Vice President of R&D for a major psychological testing company and later when most of the other competing testing companies hired him as consultant. Or why did the major personality test developer of his generation and the owner of a psychological testing company (the late Doug Jackson) never consider developing such a product?
See a pattern here? Even the folks who made the most $$$ from psychological instruments and had the most influence in the psychological assessment journals and industry did not develop a Love Site.
I concede that a Love Site may be a good place to find people you might not never meet otherwise through your social and work friends and these might be good mates or sex partners. Or they might be psychopaths, perpetuators of sexual or domestic violence, dependent individuals, or alcoholics.
So far as I can tell from the undisclosed algorithms of the dating sites and their unpublished outcomes, I have no way of knowing for sure if the sites have a good chance of producing a good outcome and avoiding a terrible (and life-threatening) one. I suspect that if there were strong scientific evidence that the sites “work” in both cases, there would be a lot of scientific research published that supports this notion. Where is the incontrovertible evidence? Can I can read it or hear it at professional conventions? Claims on TV that a lot of people got married mean little or nothing without information about comparison groups or negative outcomes.
I would have no problem concluding that the Love Sites are effective if there were psychometric and other scientific evidence that the algorithms used are valid. Without such evidence, I worry that they are more voodoo and “smoke and mirrors” than places where you can find a mate and your date will not result in a rape. Of course I cannot prove my position is right, but neither can the Love Sites. My stance is safer for individuals.
There is that old fashioned system of “meet and greet and respect the people you meet” that did produce so many humans that we now have a problem with world-wide population growth. Sometimes older methods work better if you are patient.
