Smiles exert subliminal powers. When study subjects are shown an image of a smiling face for just four milliseconds—a flash so quick, the viewers don't consciously register the image—they experience a mini emotional high. Compared with control groups, the smile-viewers perceive the world in a better light: To them, boring material is more interesting, neutral images look more positive, even bland drinks seem tastier.
