eHarmony USA site promotes itself as "Experience the magic of compatibility. Now FREE to communicate".
That is a dirty trick, you can only send an email for free to any suggested match, but you can not read answers unless you paid a subscription.
The old and new styles toggles depending the page you visit. The redesign began 6 months ago, but it is a mess until now. Just seen some problems. See screenshots as proof.
Some screens show links to Jazzed (game over since September 2012) and eHarmony Labs (game over since months).
Last year they made a mistake and revealed
eHarmony’s secret sauce. (the effectiveness/efficiency of the matching
algorithm.)
“99.7% of eHarmony’s members will not be introduced to you (translated from the failed Japanese
site)”, i.e. only 0.3% of members will be shown as a compatible partner
for you; that is the power of eHarmony’s matching algorithm (the
effectiveness/efficiency of the matching algorithm.)
0.3% means: 3 persons per 1,000 persons screened in the same range as
searching by your own! eHarmony’s matching algorithm performs really as
placebo.
Remember eHarmony uses a
Compatibility Matching Algorithm based on personality similarity with
the Big5 normative personality test and Dyadic Adjustment Scale
(invented by Dr. Graham B. Spanier in 1976) as its core. The Guided
Communication Process (a mutual filtering step) is an appendix of its
main matching algorithm. eHarmony is not "scientifically proven" because
eHarmony Labs could not prove eHarmony’s matching algorithm can match
prospective partners who will have more stable and satisfying
relationships -and very low divorce rates- 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.
