Access dating online
Pros: Access to more people and more types of people.
For more on misconceptions about online dating, read my post on 4 Myths about Online Dating. More importantly, that they don't see the problem inherent in the dishonest representation is a huge red flag.
Research suggests that those who are socially anxious (Green, 2001) or introverted (Amichai-Hamburger et al., 2002; Rice & Markey, 2009) feel more comfortable communicating online.
These individuals may have an easier time approaching people and opening up online.
I found that those who met their partners via online dating sites became romantically involved significantly sooner (an average of two-and-a-half months) than those who met in other ways (an average of one-and-a-half years). Typically, they post old photos from when they were 100 pounds lighter and 10 years younger, or they post photos that hide their body shape, which is not just a physical attribute, but a commentary on their lifestyle.
This suggests that online dating sites don’t facilitate slowly finding love the way that we often do offline. As mentioned earlier, those who are introverted or shy may find online dating more palatable than other ways of looking for love. I've had more than a few claim to love physical fitness and healthy eating, only to confess upon meeting, at which point it becomes obvious, that they actually do neither.
Thus, it is not surprising that shy people are more likely to look for romance on dating sites (Scharlott & Christ, 1995; Ward & Tracey, 2004). As discussed, one benefit of online dating sites is access to hundreds, even thousands of potential mates—but having all those options is not always a great thing.
