UCLA Professors Say eHarmony Is Unscientific and Its Customers Are 'Duped.' Here's Why.

"If you're gonna make scientific claims, act like a scientist. Or don't make scientific claims," UCLA social psychology professor Benjamin Karney says, leaning forward in his chair in his office at UCLA's Franz Hall, his voice rising an octave. "Don't pretend!"

"It just so happens that they tread on your turf! And it pisses you off," Karney's longtime collaborator and colleague, clinical psychology professor Thomas Bradbury responds, laughing. "I get that!"

On Feb. 17, Karney and four co-authors published "Online Dating: A Critical Analysis From the Perspective of Psychological Science," a secondary study that looks at established relationship science to critique dating websites that claim to have a scientific basis for matching singles, including eHarmony, Chemistry (whose methods are "almost crazy," according to Bradbury) and PerfectMatch and GenePartner (whose methods are "basically adorable," according to Karney).

Bradbury and Karney do research, write books and run UCLA's Relationship Institute together, focusing on what makes intimate relationships last.

But Bradbury didn't contribute to Karney's latest project, because, oddly enough, Bradbury works for Santa Monica-based eHarmony as a consultant on the company's Scientific Advisory Panel, a source of some tension and debate between the friends.

Bradbury, naturally, tells Karney he doesn't agree with his contention that eHarmony's pseudoscience is harming people.

"You do know that the American public has gotten hoodwinked since there was a product to be sold," Bradbury says. "The risks associated with the badness of these instruments and these devices in these sites have no long-term cost; it's just money out of someone's pocket. People are getting duped, but it's not a life-or-death situation."

UP NEXT: Why the FTC should "subject the claims of online dating sites to the same degree of scrutiny as is applied to other advertised claims that are relevant to public well-being."

Right !

I think it's what the people at en-duo.com are trying to do.

This story gives short shrift to the empirical research and other work done by the other relationship scientists at eHarmony, notably Dr. Galen Buckwalter and Dr. Steve Carter, who worked for several years before Dr. Gonzaga joined the company. A few minutes on Google should turn up published interviews and quotes. It was built on hard work, not pseudoscience. Chemistry.com, on the other hand...

I wish the very big dating sites would try to substantiate all their claims such as most marriages or relationships.

the average person uses better empirical methodology to determine which singles bar they'll have success at

The idea behind being 'scientific' is that you open up your science to cross-examination, peer review.  eHarmony is keeping their cards closer to their chest than the scientific community would like, apparently.  But then, if they did open up then their methodologies would get drawn into more cross fire and conjecture.  So they're damned if they do, and damned if they don't, and have opted for keeping their science more to themselves.

Actual online dating sites offering compatibility matching methods are only fueled by big marketing budgets and not by serious scientific evidence. No one ( eHarmony/eDarling, Chemistry, PerfectMatch, PlentyOfFish Chemistry Predictor, MeeticAffinity, Be2, RewardingLove, Parship, True, etc) can prove 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 in a peer_reviewed Scientific Paper. They are all like placebo, because* Actual online dating sites offering compatibility matching methods, when calculating compatibility between prospective mates, have less or at least the same precision as searching on one's own. [in the range of 3 or 4 persons compatible per 1,000 persons screened]* That is because they use:a) simplified versions of personality traits, instead of the 16PF5 or similar with the complete inventory (16 variables)b) 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 equations.

Latest Research in Theories of Romantic Relationships Development shows: compatibility is all about a high level on personality* similarity* between prospective mates for long term mating with commitment.*personality measured with a normative test.*similarity: there are different ways to calculate similarity, it depends on how mathematically is defined.

I had reviewed over 55 compatibility matching engines intended for serious dating since 2003, when I had discovered "the online dating sound barrier" problem.

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- 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 7.7.6.8.8.7.6.5.8.7.4.5.7.7.3.4Using a quantized pattern comparison method (part of pattern recognition by cross-correlation) to calculate similarity between prospective mates.

That is the only way to revolutionize the Online Dating Industry.

All other proposals are .............. NOISE

WorldWide, there are over 5,000 -five thousand- online dating sitesbut 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!

eHarmony turned me away, told me I had no matches whatsoever come to find out later on they turned my wife away too saying she had no matches. We have been married for going on 3 years now

Cool anecdote, bro.

EHarmony is pretty full of it.  They don't even let you see the pictures of the person until you've talked to them and by then once you see the 200 pound "curvy" woman,  you realize you've wasted your money, hurt someone's feelings, and it's too late.  Dating is not hard - looks and/or money get your foot in the door and the rest is up to you.  You're not that good looking you say?  well, just lower your expectations.

If you are lame enough to have to hire somebody to find you "somebody", well.......you get what you deserve! Really, blind dating was more fun!

No predictive algorithms cam model real life. The best solution would be to use behavioral algorithms. Startups like mymitra.com recognize this problem and have already found solutions.

And "social psychology " is real scientific....that's why their powers of prediction are so perfect just like physics....(sarcasm alert)

I think cooperation between academia and dating sites is a great idea! I would love to see some of the research the colaboration would make possible. Hopefully, eHarmony and others will realize what a benefit these scientist would be to them if they followed their suggestions!

Fact is psychology is bull fucking shit its not science.

i reject your claim because your fact is bullshit.

 I can tell by your use of swear words and absolutely no facts you have a keen grasp on science.

Boys, if you ain't banging anyone then please keep your comments to yourself.  I have dated some very nice women from EHarmony (and yes, they were very compatible.)  And I never would have met them otherwise.

Aren't there things such as string theory or hydrogen fuel cells you SHOULD be working on?

How dumb must you be? They're not saying anything about whether or not people successfully find partners via eHarmony; they're saying that eHarmony's methods are not rooted in science, as the company claims. That's all.

scientists who research relationships. now there's a contradiction in terms

Haha you'd be surprised. Sure, your physicists or chemists might get a little stereotypical neckbeardy, but in my experience, the softer the science, the hotter the girls involved. My biology program was actually more girls than guys, and fields like psychology and sociology tend to be very mixed gender and socially 'normal'. 

Maybe I'm biased but there's nothing hotter than a girl into the biological sciences...
