Dimorphism

How sex-typical your facial structure is — and why a high score here is not the same thing as a better face.

Dimorphism measures how far your face sits toward the typically-male or typically-female end of the traits that actually differ between sexes — and scores that against the ideal for the sex you selected.

It is the pillar most likely to be misread, so the caveat goes first rather than last.

Why the hair traits are weighted lightly

Deliberately. Hairline, hair length and facial hair are all genuinely dimorphic, and they are also the traits you can change this afternoon.

A pillar that let a haircut swing it would not be measuring your face. So the traits that move easily carry the least weight, and the structural ones carry the most — which has the useful side effect of making this pillar honest about what it would actually take to move.
