Sexual Dimorphism
How strongly a face expresses sex-typical traits; higher dimorphism (very masculine or very feminine) tends to rate higher.
Sexual dimorphism is the degree to which a face shows sex-typical structure. Masculine dimorphism means a strong brow, wide jaw, and defined bone; feminine dimorphism means large eyes, full lips, a small nose, and a compact midface (partly overlapping with neoteny, youthful features).
Attraction generally rewards clear dimorphism — very masculine male faces and very feminine female faces rate higher on average. It is one of the main axes an AI model weighs when scoring a face.
