Facial width-to-height ratio (fWHR) measures how broad the face is in relation to the height of the face. FWHR is correlated with such things as dominance, aggression, short term attraction, fighting ability, financial success, trustworthiness, status, etc.
Testoterone (prenatal and pupertal) seems to be the main factor in this. The Ray Peat forum says Vitamin K might have an impact on this as well, so I will throw that out there .

Can anyone parse all this information and put it into a facial recognition software so that we could have a physiognomic reference to identify leftists?
