Write to explain what phrenology is about in three sentences.
Phrenology was an attempt by a German doctor Granz Joseph Gall to analyze human behaviors from the person’s bumps on a person’s skull in the early 19th century.
He created a map of a human head that consists of 27 brain functions, such as friendship, bravery or memory, and linked them to a person’s head bumps.
Though the idea interested people of that time, it was later found unscientific to analyze human behavior.
