Physiognomy Physiognomy Physiognomy (from the Greek φύσις "physis" meaning "nature" and "gnomon" meaning "judge" or "interpreter") is a practice of assessing a person's character or personality from their outer appearance—especially the face. It is often linked to racial and sexual stereotyping. The term can also refer to the general appearance of a person, object, or terrain without reference to its implied characteristics—as in the physiognomy of an individual plant (see plant life-form) or of a plant community (see vegetation). Credence of such study has varied. The practice was well accepted by the ancient Greek philosophers, but fell into disrepute in the
Brain-to-body mass ratio have spinal cords, or in some cases, central nervous systems. Recent research indicates that, in non-human primates, whole brain size is a better measure of cognitive abilities than brain-to-body mass ratio. The total weight of the species is greater than the predicted sample only if the frontal lobe is adjusted for spatial relation. The brain-to-body mass ratio was however found to be an excellent predictor of variation in problem solving abilities among carnivoran mammals. In humans, the brain to body weight ratio can vary greatly from person to person; it would be much higher in an underweight person than an
