article "Online dating: Behind the 'science' of digital matchmaking"

"eHarmony's predictive model for attraction has improved up to 400 per cent in the past couple of years, Dr Carter says. Which isn't quite as exciting as it sounds. "We've gone from predicting a minuscule amount of the variance to predicting a very small amount."
Carter believes an algorithm for attraction is possible given how much data is available. But the real question is whether that's the direction the industry is heading.
"You talk about all this data being available," he says. "But the biggest thing in the online dating universe ... is an app that doesn't use any information except a photograph." That app, of course, is Tinder."

eHarmony, is a 14+ years old obsolete site and a HOAX, based on a big scientific fraud, only sustained by big marketing budget.

The key to long-lasting romance is STRICT PERSONALITY SIMILARITY, but ...
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.
