An inclined front of the head is an indicator. Basically bpd people have a problem with their prefrontal cortex and you can see it for many of them at their skull. Funnily Ashkenazi jews(pic related has Amy winehouse who is Ashkenazi jewish and had bpd) also have that inclined fornt of the head.

A prefrontal cortex is for emotional regulation. Asian people also have bpd quite often since some of them also have a lot of neanderthal DNA. In nations with a lot of people in sales (like China or Turkey) BPD people do not stick out and in nations with a lot of engineers (like Germany) autists do not stick out
