What to do?Two conflicting studies on relationships have been released, and the only thing they've proven is that asking science for advice is a lot like asking a room full of your drunk girlfriends for dating tips -- opinions vary, plus all that white wine is giving you a headache.

According to a study from the University of Iowa, casual hook-ups can often lead to serious relationships. At the same time, a study conducted by the Social Science Research Journal says the reason you suck at online dating is because you keep hooking up with the people you meet. The one thing that both studies (sort of) seem to agree on is that casual dating is a quick route to Lonesome Town.

The good news is, no matter what your approach, you have scientific data to prove that yet another failed relationship is not the fault of your lousy personality.
