Constitutional psychology is a now discredited theory, developed in the 1940s by American psychologist William Herbert Sheldon, associating body types with human temperament types.[1][2] The foundation of these ideas originated with Francis Galton and eugenics.[3] Sheldon and Earnest Hooton were seen as leaders of a school of thought, popular in anthropology at the time, which held that the size and shape of a person's body indicated intelligence, moral worth and future achievement.[3] Sheldon proposed that the human physique be classified according to the relative contribution of three fundamental elements, somatotypes, named after the three germ layers of embryonic development: the endoderm, (develops into the digestive tract), the mesoderm, (becomes muscle, heart and blood vessels), and the ectoderm (forms the skin and nervous system).[citation needed]

In his 1954 book, Atlas of Men, Sheldon categorised all possible body types according to a scale ranging from 1 to 7 for each of the three "somatotypes", where the pure "endomorph" is 7–1–1, the pure "mesomorph" 1–7–1 and the pure "ectomorph" scores 1–1–7.[4][5] From type number, an individual's mental characteristics could supposedly be predicted.[4] Barbara Honeyman Heath, who was Sheldon's main assistant in compiling Atlas of Men, accused him of falsifying the data he used in writing the book.[3] Questions exist about her motivations in making these accusations.[3]

The three types[edit]

Sheldon's "somatotypes" and their supposed associated physical and psychological traits can be characterized as follows:[5][6]

  • Ectomorphic: characterized as linear, thin, fragile, lightly muscled, flat chested and delicate; described as cerebrotonic inclined to desire isolation, solitude and concealment; and being tense, anxious, restrained in posture and movement, introverted and secretive.[5][6]
  • Mesomorphic: characterized as hard, rugged, rectangular, athletically built with well developed muscles, thick skin and good posture; described as somatotonic inclined towards physical adventure and risk taking; and being vigorous, courageous, direct and dominant.[5][6]
  • Endomorphic: characterized as round and soft with under-developed muscles and having difficulty losing weight; described as viscerotonic enjoying food, people and affection; having slow reactions; and being disposed to complacency.[5][6]

Academic evaluations[edit]

Sheldon's work was heavily burdened by his racist, anti-Semitic and sexist views.[1][3] There is evidence that different physiques carry cultural stereotypes. For example, one study found that endomorphs are likely to be perceived as slow, sloppy, and lazy. Mesomorphs, in contrast, are typically stereotyped as popular and hardworking, whereas ectomorphs are often viewed as intelligent but fearful and usually take part in long distance sports, such as marathon running.[7] Stereotypes of mesomorphs are generally much more favorable than those of endomorphs.[citation needed] Stereotypes of ectomorphs are somewhat mixed.[citation needed] Sheldon's ideas that body type was an indicator of temperament, moral character or potential—while popular in an atmosphere accepting of the theories of eugenics—were soon widely discredited.[3][8] The principle criticism of Sheldon's constitutional theory was that it was not a theory at all but one general assumption, continuity between structure and behavior, and a set of descriptive concepts to measure physique and behavior in a scaled manner.[6] His methodology was also criticized.[6]

Modern assessments[edit]

Sheldon's theories enjoyed a vogue as the "pop-psych flavor of the month" through the 1950s.[9] Modern scientists, however, generally dismiss his claims as outdated, if not outright quackery.[6][10][11][12] Sheldon's methodology and theories have been extensively criticized and largely discredited.[1][13]

Sheldon's photographs of naked Ivy League undergraduates, numbered in the thousands, were taken under the guise of a pre-existing program ostensibly evaluating student posture.[9] The photos were in fact collected by Sheldon to provide data for his ideas about somatotypes.[3]
