Phrenology was a belief that was popular in the 19th century, which stated that a person's character and abilities could be determined by the shape and size of their head. A phrenologist was a person who practiced or studied this belief. Today, the word 'phrenologist' is mostly used in historical and academic contexts, and is not commonly used in everyday language. So, unless you are studying history or philosophy, you are unlikely to encounter this word in your daily life.
