Facial dimorphism
How sex-typical features signal and how much it matters
Abstract
Facial dimorphism describes how strongly a face displays sex-typical features. In men, this means a defined jaw, prominent brow ridge, longer lower face; in women, larger eyes, fuller lips, narrower jaw. The literature on dimorphism is the most contested of the major aesthetic dimensions — observers don’t reliably prefer “more masculine” or “more feminine” in linear fashion.
How we measure dimorphism
VERASOMA blends multiple structural features (gonial angle, jaw width, brow ridge prominence, lip fullness, midface contour) into a single dimorphism score, calibrated against the user’s stated sex within their demographic cohort.
What the literature says
Female-typical features in women’s faces robustly increase attractiveness ratings. Male-typical features in men’s faces show mixed effects: some studies find a positive linear relationship, others find an inverted-U (moderate masculinity preferred), and observer characteristics (relationship status, hormonal state) significantly moderate the result.
Why dimorphism is contested
Dimorphism cues different things at the same time: developmental signals, social trait inferences (dominance, warmth), and partner-quality signals. Different observers weight those signals differently. Dating-context preferences differ from short-term attractiveness ratings.
Practical takeaways
A dimorphism score paired with the cohort distribution is more useful than the score alone. Sitting in the middle of your cohort distribution is often the safer-read aesthetic; pushing toward an extreme is a deliberate stylistic choice with reading-context tradeoffs.
FAQ
Are very masculine men universally preferred? No. The literature is mixed and observer-dependent.
Are feminine features always preferred in women? The effect is more consistent than for men, but still bounded — extreme femininity can read as juvenile.
