Baby face bias is a design principle in which designers use the generalized human interpretation of baby-faced features (such as large eyes, round head, small nose and mouth) to represent and codify naiveté, innocence and kindness. By emphasizing or exaggerating baby like features in faces, a design can evoke a feeling of protection, ownership, or forgiveness in a viewer. Alternatively. more angular features, less elongated heads, and other more adult features are less likely to be interpreted as innocent, kind, or naïve.
