A prominent psychologist has suggested that a subtle posture could reveal clues about psychopathy, a personality disorder often hidden by charm and manipulation. Susan Krauss Whitbourne, professor emerita at the University of Massachusetts Amherst, said research indicates that individuals who adopt large, open poses are more likely to exploit others.
Study Links Posture to Psychopathic Traits
Whitbourne highlighted a series of five studies conducted by researchers at McGill University in Canada. The studies examined the relationship between posture and personality traits associated with psychopathic tendencies, such as manipulativeness, competitiveness, and belief in social hierarchies.
In four of the studies, participants submitted photographs of themselves standing in natural positions. In the fifth, volunteers visited a laboratory where researchers recorded physical measurements. The research involved 608 young adults in total.
Early findings revealed that people who stood in more upright positions tended to score higher on personality traits linked to psychopathy. These posture patterns remained consistent over time, suggesting the behavior was stable rather than random.
Dominant vs. Submissive Stances
In another phase of the study, participants were instructed to adopt either dominant or submissive stances. Those assigned submissive positions stood with stooped shoulders and bent-forward postures, while those instructed to appear dominant stood upright with their hips pushed forward and torsos leaning slightly back.
However, researchers noted no evidence that simply changing posture altered a person's mental state. In the final stage, scientists confirmed earlier findings and expanded the range of personality traits examined, including psychopathy, manipulativeness, competitiveness, and belief in rigid social hierarchies.
The researchers suggested that individuals displaying more dominant postures may be driven by a strong desire to avoid appearing weak or subordinate. They also noted that standing tall and projecting confidence can influence how others respond, potentially reinforcing dominant behaviors over time.
Implications for Understanding Psychopathy
Whitbourne explained that one major set of cues that can tip you off about someone's intention to boss you around is an open, erect, and expanded posture. Someone who is ready to give in to another person is more likely to slump over and may close up a bit.
She added that people who do not have this dominant orientation are able to vary their posture. Those participants who scored lower on these undesirable traits adopted a wider range of stances rather than always trying to overpower others by appearing strong and tough.
A psychopath refers to individuals with antisocial, manipulative, and callous traits, like fearlessness, superficial charm, and lack of empathy. Often highlighting dramatic or criminal behavior, they are described as cold-hearted, risk-taking, and lacking conscience.
