First Impressions Can Be Influenced by Body Shape Stereotypes

A new study finds that when we meet new people, our first impressions of their personality may depend, at least in part, on their body shape.

“Our research shows that people infer a wide range of personality traits just by looking at the physical features of a particular body,” said psychological scientist Ying Hu of the University of Texas at Dallas, first author on the research.

“Stereotypes based on body shape can contribute to how we judge and interact with new acquaintances and strangers,” she said. “Understanding these biases is important for considering how we form first impressions.”

Previous research has shown that we presume a considerable amount of information by looking at other people’s faces, but relatively little research has explored whether body shapes also contribute to these judgments, according to the researchers.

“We wanted to know whether we could link personality descriptor words to body shape in predictable ways,” said Hu, a PhD student in the UTD School of Behavioral and Brain Sciences. “That is, do people look at a person’s body and make snap judgments about whether the person is lazy, enthusiastic, or irritable?”

The research team created 140 realistic body models, 70 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, the researchers explained.

Using these models allowed the researchers to know the precise physical measurements of each body shown in the study.

Then 76 undergraduate participants viewed a set of models. They saw each body from two angles and then chose from 30 trait words shown on screen those that 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 (enthusiastic, extraverted, dominant) or negative (quiet, reserved, shy), the researchers reported.

The researchers analyzed whether participants consistently associated specific traits with certain types of bodies.

What they discovered is that study 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.

The participants also perceived classically feminine (pear-shaped) and classically masculine (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, the study discovered.

In additional analyses, the researchers said they found they could reliably predict personality trait judgments from specific combinations of different body shape features.

“To our knowledge, this is the first study to consider the role of more nuanced aspects of body shape — beyond height and weight — in personality judgments about people,” said Dr. Alice O’Toole, coauthor and a professor at UTD.

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 added.

According to the researchers, the tendency to infer personality traits from body shape is likely universal. However, the exact inferences people make vary according to their culture, ethnicity, and even age, they said.

It remains to be seen how other characteristics, such as attractiveness or gender, interact with body shape to influence the inferences that people make, the researchers added.

The study was published in Psychological Science, a journal of the Association for Psychological Science.
