eHarmony scams its members with the Big Five Normative test.eHarmony is ONLY a 16+ years old obsolete site and a HOAX, based on a big scientific fraud, only sustained by big marketing budget.
The Big Five normative test used by eHarmony, had been proven/revealed as an incomplete and incorrect model to assess/measure personality of persons.
Moreover eHarmony was copycatted in several countries like the online dating sites EliteSingles in Canada, Australia, USA, UK; eDarling in Spain, German, France, Russia; also TeAmo in Russia is another copycat of eHarmony; esync (eSynchrony) in Singapore, MiMediaManzana in Colombia, Peru, Mexico, Chile, etc.
New compatibility indicators by eHarmony are .... only for fun, for entertainment purposes, with no scientific basis at all!
Very easy to copycat eHarmony, but very difficult to innovate: a 100 times better algorithm than eHarmony.
The key to long-lasting romance; COMPATIBILITY is: STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests".
