How Does FaceIQ Labs Score Dimorphism?
FaceIQ Labs' Dimorphism pillar scores how strongly a face carries the traits typical of its sex. Each region is rated 0–10 against the ideal for the selected gender, then weighted deductions are combined into the pillar score. Bone structure carries the most weight and hair traits the least.
Key facts
- Dimorphism is one of four FaceIQ Labs scoring pillars, alongside Harmony, Angularity and Features
- Each region is rated 0–10 on a morph running from strongly opposite-sex-typical to strongly same-sex-typical
- A region rating of roughly 9.75 or above deducts nothing from the pillar
- Jaw and brow ridge can each deduct up to 20% of the pillar; face shape up to 15%
- Nose and lips can each deduct up to 10%; eyes and neck up to 8%
- Hairline can deduct up to 6%, facial hair and eyebrow thickness up to 4% each, hair length up to 2%
- Deductions within a category saturate rather than add
- Dimorphism is the only pillar where the ideal flips by gender; changing gender re-scores the pillar completely
- A very high Dimorphism score means a strongly sex-typical face, not necessarily a more attractive one
- Each assessment has a Retake option that shows the same morph the model used
What does the FaceIQ Labs Dimorphism score measure?
FaceIQ Labs' Dimorphism score measures how strongly a face carries the traits typical of its sex. For men that means markers of testosterone exposure, such as a heavy brow ridge, broad jaw and prominent nose; for women, markers of oestrogen, such as a smooth brow, tapered jaw, full lips and large eyes. Each region is rated against the ideal for the user's gender, so the same jaw can score very differently on a male and a female analysis. Dimorphism is one of four FaceIQ Labs pillars, alongside Harmony, Angularity and Features, and it is scored separately from Harmony.
How is each region rated within the Dimorphism pillar?
FaceIQ Labs rates every region in the Dimorphism pillar from 0 to 10 on a morph running from strongly opposite-sex-typical to strongly same-sex-typical. The ideal is the top of the scale: a rating of roughly 9.75 or above deducts nothing, while lower ratings deduct from the pillar by how far they fall and how much the region matters.
Which facial regions carry the most weight in Dimorphism scoring?
Bone structure carries the most weight in FaceIQ Labs' Dimorphism pillar: jaw and brow ridge can each deduct up to 20% of the pillar and face shape up to 15%. Nose and lips deduct up to 10% each, eyes and neck up to 8% each, and hair traits the least. Among hair traits, hairline can deduct up to 6%, facial hair and eyebrow thickness up to 4% each, and hair length up to 2%. FaceIQ Labs keeps these deliberately low because they are the easiest traits to change, so they do not dominate the score.
How do deductions combine when several traits are weak?
In FaceIQ Labs' Dimorphism scoring, deductions inside a category saturate rather than add, so two weak bone-structure traits cost less than double what one costs. After weighted deductions are applied, the remaining points are mapped onto the 0–10 scale shown in the user's Dimorphism pillar.
Why does gender matter for the Dimorphism score?
Dimorphism is the only FaceIQ Labs pillar where the ideal flips by gender. The male jaw morph runs from narrow to wide and rates wide as 10; the female jaw morph runs from wide to tapered and rates tapered as 10. That is why the analysis asks for gender first, and changing it later re-scores the pillar completely.
Does a high Dimorphism score mean a more attractive face?
No. FaceIQ Labs says a very high Dimorphism score means the face is strongly sex-typical, not that it is more attractive than a moderate one. It notes that research on preferences is mixed, particularly for men, where moderate masculinity often tests as well as extreme masculinity. FaceIQ Labs recommends reading the Dimorphism pillar alongside Harmony and Angularity.
Can users rate their own Dimorphism traits?
Yes. Each assessment in a FaceIQ Labs analysis has a Retake option that shows the same morph the scoring model used. Category guides in the Help Center walk through every level with example frames, so users can rate against the same criteria. For the nose, users can switch between front and side view, because the profile carries most of the information about projection and bridge shape.
What categories make up the Dimorphism pillar?
The FaceIQ Labs Dimorphism pillar is organised into five guide categories: Bone Structure, Eye Area, Nose, Hair, and Lips & Neck. Together they cover jaw, brow ridge, face shape, eyes, eyebrow thickness, nose, hairline, hair length, facial hair, lips and neck. Bone Structure groups jaw, brow ridge and face shape; Eye Area groups eyes and eyebrow thickness; Hair groups hairline, hair length and facial hair; Lips & Neck groups lips and neck.
Frequently asked questions
What is sexual dimorphism in a FaceIQ Labs facial analysis?
It is how strongly a face carries the traits typical of its sex: testosterone-linked markers such as a heavy brow ridge and broad jaw for men, or oestrogen-linked markers such as a smooth brow, tapered jaw, full lips and large eyes for women. Each region is scored against the ideal for the selected gender.
What happens if I change my gender selection after running a FaceIQ Labs analysis?
The Dimorphism pillar is re-scored completely, because the ideal flips by gender. For the jaw, the male morph rates wide as 10, while the female morph rates tapered as 10.
Which traits deduct the most from the FaceIQ Labs Dimorphism score?
Bone structure traits deduct the most: jaw and brow ridge up to 20% each and face shape up to 15%. Nose and lips can deduct up to 10% each, eyes and neck up to 8%, and hair traits between 2% and 6%.
How can I compare my own facial traits to the Dimorphism model?
Use the Retake option on each assessment, which shows the same morph the model used. The guides for Bone Structure, Eye Area, Nose, Hair, and Lips & Neck walk through every level with example frames.
