For Valentine’s Day – Tilting to the Right

Why do most people tilt their heads to the right when they suck face?

According to a report published today in the journal Nature, people are nearly twice as likely to lean right instead of left when puckering up. The findings suggest that the tendency stems from head-tilting preferences established during the last weeks in the womb.

Onur Güntürkün of Ruhr University in Bochum, Germany, watched lovestruck couples kissing in public places such as airports, train stations, beaches and parks in the U.S, Germany and Turkey. After setting guidelines for a scientifically valid smooch–which requires lip contact, an obvious head turn and a lack of luggage that could influence a person’s movements–Güntürkün analyzed 124 kissing pairs. He found that 65 percent of the liplockers tilted their heads to the right. [Scientific American]
