Participants then have to choose how much time they are willing to commit the inferior date from the online service and the superior match that is the blind date. It turns out that a person’s preference for the online date is correlated with how much they had invested in the service.
Those who paid nothing, or very little, for the search were much less willing to choose the online date over the blind date than those who paid a higher fee.
There is an argument to be made, though, that if you do find a match on an online dating site, that match is more likely to commit to meet if they have paid a fee for the service.
A study published last year tests this theory in an online dating simulation where a participant "pays" a fee to search online for potential dates after answering a series of questions describing their perfect mate.
At the end of the search they are informed that a match has been found but that he/she does not have all the qualities the participant is has been searching for (I think we all can relate to that experience).
