I’ve been using online dating as a method of meeting new people, augmenting my social life, etc. for the past ~2.5 years. In that time, I’ve noticed that there is a much better chance of there being a second date with someone if she voluntarily tells me her full (first and last name) before the first date as compared to someone who doesn’t divulge her last name.
So, I did the numbers this evening to see if my theory held true:
Since mid-2003 I’ve met 15 women through online dating (all through The Onion Personals and its companion sites).
Group 1: 10 of them told me their last names before I ever met them in person (and in most cases before any phone calls were made). Of these 10 first dates, 7 resulted in second dates. That’s 70%.
Group 2: The other 5 did not reveal their last names prior to the first date (or ever). Zero of these first dates resulted in second dates. That’s 0%.
My first attempt to explain this discrepancy is that the women in Group 2 were more on the border and less enthusiastic about meeting me, and thus didn’t want to tell me their last names. That may be true, but in most cases, of the women who did reveal their last names, most did so because their last names were part of their email address, and usually did so pretty early on in our pre-date correspondences. I never have asked anyone their last name that I met through online dating. I figure that if they want to tell me, they will.
So, based on this, I am wondering if anyone has seen (or bothered to look for) this trend. If so, any speculations as to the cause? Are secretive people less likely to go on second dates regardless of how well (or awful) the first one went? In order to save time, should I no longer arrange first dates with women who don’t tell me their last names upfront?
