Many of us have a certain pose for photos, but have you ever noticed which side you naturally turn?

According to US science writer Sam Kean, people tend to turn to the right and show the left side of their faces.

That might be because the left side of our faces looks better than our right side. This may have something to do with our brain. The right side of the brain, which controls the left side of the body, deals more with emotions. So the left half of faces are often more expressive(富有表现力的), The Atlantic reported.

During studies, it is found that more than 60 percent of famous paintings since the 14th century showed people’s left side of the face.

But when it comes to self-portraits, artists have traditionally drawn themselves from the right.

Yet this doesn’t mean the left side phenomenon(现象) is wrong. As Professor Marco Bertamini from Liverpool University explained, self-portraits are usually painted through a mirror. For example, if an artist shows his left side to a mirror, and draws what he can see, the final picture on the paper would show the head facing to the right.

The front-facing camera on smart phones works the same way as a mirror. When people take selfies(自拍照) using a front-facing camera, most of them take a photo with their head facing to the right.

“Our results show that a preference(偏爱) for self-portraits showing one’s left side, even if this appears as a right face in the mirror-reversed(反转的)display,”Bertamini told The Guardian.

Next time, when you take a photo, remember to show your better side to the camera.
