Phrenology is a passé theory in psychology that centered around the belief that you could understand a person’s mental faculties and character traits based on the shape that person’s skull. Phrenologist used to make a healthy living rubbing the temples of patients, and examining the various bumps and lobes on their cranium, before things like the scientific method starting infiltrating the medical field.

Phrenology reached it’s peak during the late 1700’s – early 1800’s, and was superseded by the next fad in the industry: psychoanalysis. This vastly superior theory of psychology was dubiously famous for claiming cocaine as a panacea; and for a fun factoid, Sigmund Freud did enough nose candy to kill a small elephant.
