Smile. Pretty obvious, right? In a study done in Wyoming, 100 women were asked to look at a photo of a woman in 4 poses: smiling with an open-body position, smiling with a closed-body position, not smiling/open-body and not smiling/closed-body. The results suggested that the women liked the photos where there was a smile, regardless of body position. As well, when interacting online, a different study found that a smiling profile photo/avatar goes a long way in making you better liked. Plus, if you smile when you first meet someone, you’ll be better remembered.
