Your body shape can tell a lot about you
Turns out, people tend to judge a book by its cover, as they analyse the first impressions of others’ personality, which may depend, at least in part, on their body shape. According to research, people infer a wide range of personality traits just by looking at the physical features of a particular body.
“Stereotypes based on body shape can contribute to how we judge and interact with new acquaintances and strangers. Understanding these biases is important for considering how we form first impressions,” said scientist Ying Hu of the University of Texas at Dallas, who is also the first author on the research.
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.g., enthusiastic, extroverted, dominant) or negative (e.g., quiet, reserved, shy). The researchers analysed 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.g., pear-shaped) and classically masculine (e.g., broad-shouldered) bodies as being associated with “active” traits, such as being quarrelsome, extraverted, and irritable. 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 an additional analysis, the researchers found that they could reliably predict personality trait judgments from specific combinations of different body shape features.
