Best Selfie Angle: Your left cheek or right cheek? Ancient portraits reveal

Another study showed that there was a consistent left-profile bias at 50,000 objects from the stone age to the present and these were found after the early Greeks.

Sam Kean said that this happens “no matter whether the artists themselves were left- or right-handed.”

“Artists tend to paint self-portraits in the mirror, which makes the left half of the face appear on the right side of the canvas. So this ‘exception’ might actually confirm the bias,” he explained when it comes to self-portraits that are mostly facing right.
