Best quote from Body Type and Personality: Sheldon’s Theory of Somatotypes
We are not fixed by the 'germ layers' of our birth; we are a constant work in progress, a complex interplay between the genes we inherited and the world we inhabit.

Frequently Asked Questions
William Herbert Sheldon was an American psychologist who developed the theory of somatotypes in 1940. He proposed that the human body serves as a map of the mind, suggesting that physical structure is inextricably linked to psychological function. By categorizing individuals into specific body types, Sheldon believed he could create a rigorous science to predict whether a person was a natural leader, a sensitive poet, or a relaxed socialite based on their physical build.
Constitutional psychology, also known as biotypology, suggests that our physical structure is an integrated system where form dictates character. This field of study, championed by Sheldon and his predecessor Ernst Kretschmer, looks at embryonic development and germ layers to explain personality traits. The theory posits that measuring physical attributes, such as the roundness of a torso or the width of shoulders, provides a shortcut to understanding a person's heart and temperament.
Ernst Kretschmer was a German psychiatrist who served as a predecessor to William Herbert Sheldon in the study of biotypology. Together, they spent decades trying to prove that physical form is a reliable indicator of psychological traits. Their work focused on the idea that instinctive snap judgments about body types—such as assuming a thin person possesses nervous energy—could be backed by scientific observation of the link between physical structure and internal disposition.
