This used to be a very big deal in the upper class populations during the 1900’s. It was called Phrenology;
A pseudomedicine primarily focused on measurements of the human skull, as indicative of mental faculties and traits of character, especially according to the hypotheses of Franz Joseph Gall; a German doctor, and such 19th centuray adherents as Johann Kaspar.
Later on, Phrenology was for the most part discredited by scientific research.
I’ve seen more than a few Caucasians with the neanderthal skull and brow line over the years. Consistently, they too have been low on the socioeconomic ladder.
