Amy Cuddys infamous 2012 Ted Talk claimed that power posing was the key to confidence. Critics shut down her theory for years — for good reason — but the latest research indicates that there may be some truth in it after all. A new study published in the American Psychological Associations journal Psychological Bulletin found that yes the way you stand can actually play a huge role in your level of confidence.
“People engaging in dominant or upright body positions report higher self-esteem and experience more positive emotion than people who engage in contractive or slumped body positions” says study author Robert Körner a psychologist at Martin Luther University Halle-Wittenberg in Germany. In other words the researchers found that those who stand tall feel better overall according to data compiled from 130 different studies.
The researchers collected and analyzed past studies to determine whether posture influences a persons self-perception behavior and hormone levels. Examining both published and unpublished studies Körners team found a small-to-medium connection between posture and confidence.So how could posture affect confidence? “Through the life-course we learn to associate large and expansive body positions with competence and self-esteem” Körner says. “For example tall people are more often in leadership positions. Parents are perceived as superior from the perspective of a child.” These learnings he continues lead people to develop associations between height and confidence.
This allows “the psychological concept of confidence” to become grounded in the body he says. “Thus if a person engages in expansive body positions concepts that are associated with expansiveness become activated and the person ultimately feels more confident.” Although people may feel more confident it remains to be seen if they act more confident when standing tall. Some research has found that power posing does affect behavioral traits like task persistence and antisocialness but other studies have not. Only those that have found bigger effects have been published which means researchers havent been able to examine studies with less significant results a phenomenon known as publication bias. “For these reasons it is not entirely clear how strong body positions affect behavior” Körner says.
Körners study also debunked controversial claims from previous research that certain poses can boost the production of hormones such as testosterone and cortisol. His team found minimal support for these claims. There are some study design limitations that prevent the researchers from being able to say that standing tall can directly make you more confident. Most of the studies they analyzed didnt have a control group the researchers didnt compare people power-posing to people standing in a neutral position. Instead they asked participants to adopt either a dominant open or submissive posture.
Control groups Körner explains are extremely important to conducting accurate studies. “This would allow us to test whether the effect of the body positions is driven by power poses and upright postures or by submissive poses and slumped postures.” So its unclear whether an upright posture actually can make you confident or if slumping tanks your self-esteem. Or maybe both. Additionally almost all the studies were conducted in WEIRD societies or Western Educated Industrialized Rich and Democratic. Therefore its not entirely clear whether findings across other cultures would be the same although results didnt differ across genders and age groups.
Try it yourself. Next time you stand stand tall. After all you might just feel more confident.
