Phrenology is a science that was developed around 1800 by a man named Franz Joseph Gall.
Phrenology claims the personality of a human being is related to the size and shape of their skull, including the location, size, and shape of any bumps or depressions in the skull.
The established medical community of the time dismissed Phrenology as “quackery”, which is defined as “unproven or fraudulent medical practices”. That dismissal of Phrenology as a valid science has continued into the present day.
While the exact details and claims of Phrenology may not be true, the basic concept of Phrenology is true. The size and shape of the skull, including the location, size, and shape of any bumps or depressions in the skull, are an indicator of the character, personality, and mentality of a human being.
