Take pictures of men, have women rate them for attractiveness. Choose pairs who got similar ratings. Extend their shins in Photoshop. Now have (other) women compare “man A” vs “man B with extended shins”, and other women compare “man A with extended shins” vs “man B”.
This could be verified experimentally.
