I don't think this is the actual problem. I believe it's often a problem that people either don't know what they want, or they are willing to accept less in the short term than what they want in the long term (which leads to terrible relationships more often than not).
There are also plenty of people, both male and female, who just want short term sex but firmly believe that they should throw up a charade in order to get it.
this is an out-dated, stale, and dare i say sexist interpretation of modern gender relations.
there are lots and lots of men looking for relationships and completely failing to even get a date, much less get laid. there are also plenty of women who just want to hook up with hot caddish guys and have no interest in a LTR any time soon.
you don't need to look any further than tinder or reddit to find plenty of examples of both.
I've never actually seen this proven. Did you scrape profiles? OkC staff have repeatedly claimed that the ratio is around 50/50 for major metro areas:

Among the 26,939 users with a UK email address, for example, there are just 1,596 who identified as female: a ratio of one woman to every 16 men.[1]

Social networks are important to making a dating system work. Facebook is the most successful dating app in the world by far.
even after you start dating, if you emotionally invest yourself in any one person too fast, it's extremely unattractive.
