Or the fact that these sites offer too many choices.
Research shows that having too many choices overwhelms us, and can cause us to make either poor decisions or no decision at all.
A second reason is that online dating uses side-by-side comparisons.
What really matters aren't these superficial, surface-level qualities, but rather how two people interact.
John Gottman, a renown expert on marital stability and relationship success, has discovered that in predicting happy relationships, how couples resolve conflicts and whether they exhibit positive affect towards one another matters most.
His research points to interactions, affect and behavior as the indicators of relationship outcomes, rather than searchable traits that these online dating services use for matching.
Algorithmic matching services like e Harmony and Ok Cupid don't fare much better.
Research shows no evidence of algorithm-based matching being effective.
These algorithms focus on searchable traits that aren't predictive of relationship success (measured by long-lasting relationships and satisfaction).Searchable characteristics consist of those easily taken from a person's profile, such as age, religion, income level and race.According to online dating literature, dating services can't really improve relationship outcomes.On dating sites like Match.com, which allow users to make their own dating decisions, daters have difficulty meeting the right partners.Studies show that they are unable to make successful selections.This could be because, as humans, we have a tendency to not know what we really want.
