Another is to take inspiration from Facebook's playbook and blame the algorithm. eHarmony claims that its algorithm is "based on scientific theories in the relationship literature of assortative mating," and provided a couple of studies as evidence that its claims hold water. > The problem is, one of the studies was apparently a survey taken by couples that proactively told the dating site about their impending nuptials. That's in addition to eHarmony allegedly incentivizing them to do so. Pretty far from a random sample, no?
