WTF? 11 Weirdest Dating Studies Of 2011 [GALLERY]

People who research love and relationships (as well as the media) often attract readership to their studies by highlighting the most illogical, shocking or "weird" results. I cannot tell you how many times I've clicked on studies with headlines like "women like their cell phones 50 gazillion times more than sex," only to find out that the study was done by a cell phone company that wants you to buy their product.

But once in a while, I come upon a dating/relationships study with findings that are actually surprising. This year, for example, I learned about "partner betweenness," a phenomenon that occurs when the female partner in a long-term relationship has stronger relationships with her husband's friends than he does, effectively coming between him and his friends. (This undermines the man's feelings of autonomy and privacy, which researchers say are central to traditional concepts of masculinity.) Who knew? 

This year, we found out that men are more vain than women, deep voices make women pay attention, and that men prefer to date women who have been dumped. Here, we've rounded up 11 dating studies from 2011 with weird, unexpected results.
