Sheldon went a step further and tried to prove, using questionable methods , that one could reliably predict personality and character based on body shape. The participants were 76 undergraduate students 17 men; average age, 20 years from the University of Texas at Dallas. The stimuli comprised of random, computer generated bodies 70 males, 70 females in neutral standing poses; these images were generated using the skinned multi-person linear model, which is based on the Civilian American and European Surface Anthropometry Resource CAESAR data set.
See video below. The stimuli also included a list of traits — based on the Big Five or the five-factor model of personality extraversion, agreeableness, conscientiousness, neuroticism , and openness to experience.
The final list included 30 terms divided into the five personality categories. Each of the five domains contained six positive and negative personality traits: For example, neuroticism included the three positive traits of calm, easy-going, and self-confident; and the three negative traits of irritable, anxious , and moody.
For each trial, participants saw two views of a computer-generated body from the front and a degree angle , along with the trait list; they then decided whether any of the 30 traits applied to the body. This procedure was repeated until all bodies were rated. Researchers visualized the results separately for male and female bodies.
For both men and women, one axis of body-trait space was related to weight. In general, heavier bodies were linked with more negative terms, and skinnier bodies with more positive ones.
Body weight also corresponded with conscientiousness-related traits. Namely, heavier bodies were more likely to be judged as lazy, disorganized, and careless; slimmer bodies as careful and self-disciplined. The authors speculate that the observed link may be explained by how conscientiousness influences body weight via lifestyle choices.
For example, disciplined and careful individuals are expected to exercise more and watch what they eat. The vertical axis of body-trait space separated traits according to agency, with more agentic personality traits e. Patterns involving this axis appeared more complex and gender -dependent.
Overall, more classically masculine i. wider shoulders and classically feminine shapes i. pear-shaped were associated with greater agency; more rectangular bodies were linked with greater passivity. The bodies of seemingly reserved and passive women were less curvy and more rectangular and heavy; extraverted women, in contrast, had trimmer and more pear-shaped bodies.
Using these models allowed the researchers to know the precise physical measurements of each body shown in the study. A total of 76 undergraduate participants viewed a set of models -- they saw each body from two angles and indicated whether 30 trait words shown on screen applied to that body.
The trait words reflected dimensions of the Big Five personality traits a common measure of personality used in psychology research typically seen as positive e.
The researchers analyzed whether participants consistently associated specific traits with certain types of bodies. Generally, participants judged heavier bodies as being associated with more negative traits, such as being lazy and careless; they judged lighter bodies as having more positive traits, such as being self-confident and enthusiastic.
Furthermore, the participants perceived classically feminine e. Male and female bodies that were more rectangular, on the other hand, were associated with relatively passive traits, such as being trustworthy, shy, dependable, and warm.
In additional analyses, the researchers found that they could reliably predict personality trait judgments from specific combinations of different body shape features. The tendency to infer personality traits from body shape is likely universal, the authors argue, but they note that the exact inferences people make will vary according to their culture, ethnicity, and even age.
And it remains to be seen how other characteristics, such as attractiveness or gender, interact with body shape to influence the inferences that people make.
These findings add a new layer to the science behind first impressions, revealing "the complicated and value-based judgments that people make about strangers based only on their bodies," Hu concludes.

Sheldon's "somatotypes" and their associated physical and psychological traits were characterized as follows: [3] [8] [11].

Understanding these Fat intake and food labels is important for considering how we form first impressions. Previous research has shown that we infer a considerable amount of social information by looking at other people's faces, but relatively little research has explored whether body shapes also contribute to these judgments. Hu and colleagues created realistic body models, of which 70 were female and 70 male. The three-dimensional renderings were generated from random values along 10 different body dimensions, using data from laser scans of actual human bodies. Using these models allowed the researchers to know the precise physical measurements of each body shown in the study.

The leaner a body, the better a person was assumed to be, with characteristics of determination and curiosity. Read: How intelligence leads to stereotyping.
The formal connection between personality and body type in academic research goes back to , when the psychologist William Sheldon established the somatotypes, which are three generalized body shapes that he theorized could be linked biogenetically to personality: ectomorphs, mesomorphs, and endomorphs.
Ectomorphs are people who are tall and thin, and Sheldon expected them to be shy and anxious. And for good reason: Somatotypes were a direct result of the academic popularity of anthropometry and eugenics before World War II. He then assigned each shape personality traits based on his own observations and assumptions about personality and physical appearance.
In doing so, he developed the now-discredited field known as constitutional psychology, which is the study of the link between body and behavior. Eventually, spurred by outcry from the parents of the well-heeled young women he was photographing nude and by the repudiation of his techniques by a longtime research partner , schools washed their hands of him and he died in obscurity.
His papers are now kept out of easy public reach at the National Anthropological Archives, and they require curator permission to view. Although his work has attracted some lingering interest—the writer Camille Paglia discussed somatotypes prominently in her book, Sexual Personae , and they are still routinely used in some parts of the bodybuilding community —it fell out of scientific favor before his death in Read: The shape of your head and the shape of your mind.

Half were female, half were male. The researchers then showed these models each from two different angles on a computer screen to 76 undergraduates students.
The screen also contained 30 words representative of all dimensions of the Big Five personality traits, which are commonly used in psychology research to assess personality. The students were asked to identify the traits they thought were most applicable to each body model. Furthermore, the associations uncovered in the study were so strong that the researchers were able to reliably predict which traits the students would apply to specific combinations of different features of the body shapes.
The study comes with several important caveats. Most notably, its participants were young undergraduates attending the same university. If they had encountered the body shapes in the real world — as actual people — they might have linked different personality traits to them.
We should resist the impulse to make those snap inferences, however, as the idea that body shapes are linked to personality traits has absolutely no basis in scientific fact — and can lead to harmful stigmas.

William Sheldonan American psychologist and physician back in In his thinking, mesomorphs broad-shouldered, well-muscled, straight-backed were energetic, courageous and desirable. Ectomorphs thin, usually tall, lightly muscled were neurotic, introverted and intellectual.
