Conor Clarke contemplates it:
Everyone wants to find good dates — and are wiling to lavish them with expensive dinners and whatnot — and avoid bad ones. But there's a catch. Everyone in the market can pretend to be a good type — say, by lying on their Internet dating profiles. So now you have this market where everyone is presenting themselves as a good type. Some of them are probably lying. You don't know which ones, so you'll value every potential date a little bit less than as good as they look.
(Even in the real world, people are understandably willing to offer less for the prospect of a seemingly good date when they know they might really end up with a psycho killer or a gold-digger or a bore.) That's smart for you, maybe, but it's bad for the good types. Some of them will surely think they're much better than the tepid replies they get from other singles, and they'll respond by leaving the dating market. "Screw OkCupid," they'll say. "I deserve more!"
