Many studies, using different averaging techniques, including the use of line drawings and face profiles, have shown that this is a general principle: average faces are consistently more attractive than the faces used to generate them. Furthermore, if a female composite (averaged) face made of 32 different faces is overlain with the face of an extremely attractive female model, the two images often line up closely, indicating that the model's facial configuration is very similar to the composite's. See, for example, the illustration of Jessica Alba on the right.
