Phrenology
Phrenology is the analyzing of the variance in the shapes and sizes of the skull of different races. Phrenology is craniology taken one step further to use the measurements found as implications on the personal character and mental abilities of a human being. These “scientific” approaches taken in the Enlightenment era by the ambitions of the explorative world, make the measurements of a mouth, chin, nose and forehead have a more social and outward effect than they may have as simple findings for white scientists. After these methods, society gets to act like their prejudice is backed by research.
