Only 4% of women around the world consider themselves beautiful. Based on this facet, Dove, a personal care brand owned by Unilever, made a video that tells you "You are more beautiful than you think." The short film used an FBI-trained sketch artist to draw women first based on their own self-perception and then based on that of a stranger. The stranger's descriptions were regularly more stereotypically attractive and similar to what the subjects actually looked like.
