2. Phrenolgy Phrenologists believed that the mind has a set of different mental faculties, with each particular faculty represented in a different area of the brain. These areas were said to be proportional to a person's propensities, and the importance of the given mental faculty. It was believed that the cranial bone conformed in order to accommodate the different sizes of these particular areas of the brain in different individuals, so that a person's capacity for a given personality trait could be determined simply by measuring the area of the skull that overlies the corresponding area of the brain.
4. Physigonomy Physiognomy (Greek Language physis , nature and gnomon , judge, interpreter) is a theory and a folk science based upon the idea that the study and judgement of a person's outer appearance, primarily the face, may give insights into their character or personality.
