“Power posing significantly increases confidence and success.”

Two recent meta-analyses provide evidence of a statistical difference between expansive and contracted poses for self-reported feelings and overt behavioral outcomes, but not for hormones, after correcting for publication bias (n = 96 reports , n = 48 reports [27, but see 28]). The most reliable available evidence to date, from large pre-registered studies and registered reports, suggests that the power pose effect on self-reported feelings of power is real, but small (n = 1002 participants , n = 1071 participants ).

In a meta-analytic review, researchers analyzed data from 88 studies with 9,779 participants. They found that compared with low-power poses, high-power poses were linked to more positive reports of self-perception and, to a lesser extent, behaviors indicative of confidence, such as task persistence.

Large analyses seemed to be indicating that while original neuroendocrinal and behavioural claims could not be supported, some promise still remained in the subjective domain… with power posing capable of facilitating significant and potentially beneficial feelings of power in individuals. Their p-curving analyses revealed 'very strong' and 'strong' evidentiary support across their analyses, including those studies specifically examining feelings of power.

Marcus Credé... says there is not a single study to support the claims that power posing works... In a new commentary... Credé reviewed every study on power posing... and found a significant flaw... Striking a power pose... is not going to boost your confidence or make you feel more powerful.

A new meta-analysis from the Department of Psychology and Behavioural Sciences at Aarhus BSS reveals important deficiencies in previous studies that suggest that by power posing for two minutes, you can manipulate yourself into becoming more assertive and thus improve your performance at job interviews. “The result is a meta-analysis in which we show that it is most likely not the power poses that help people gain self-confidence. In fact, there appears to be no difference between a neutral posture or a power pose. So ff anything, research shows that a hunched or closed posture can seemingly have a negative effect and that 'not hunching' is as great as adopting a power posture,” says Emma Elkjær Poulsen.

Cesario's research and the findings from the journal he co-edits do find that holding power poses makes people feel more powerful, but that's where the effect ends. “Feeling powerful may feel good, but on its own does not translate into powerful or effective behaviors,” Cesario said. “These new studies, with more total participants than nearly every other study on the topic, show – unequivocally – that power poses have no effects on any behavioral or cognitive measure."

The evidence seems to be stronger that power posing can help you feel more confident, but largely lacking when it comes to effects on physiology or behaviours... a comprehensive review from 2020 suggested the effects on confidence are actually more likely due to avoiding constrictive postures rather than adopting expansive ones.

Now comes the most definitive evidence to date suggesting that power poses do not improve your life. 'These new studies, with more total participants than nearly every other study on the topic, show -- unequivocally -- that power poses have no effects on any behavioral or cognitive measure,' said Joseph Cesario, MSU associate professor of psychology. Dana Carney, a co-author of the original 2010 power posing study, stated on her website: 'As evidence has come in over these past 2-plus years, my views have updated to reflect the evidence. As such, I do not believe that power pose effects are real.'

The result? In addition to causing the desired hormonal shift, the power poses led to increased feelings of power and a greater tolerance for risk. Not surprisingly, high-power posers of both sexes also reported greater feelings of being powerful and in charge. In addition, those in the high-power group were more likely to take the risk of gambling their $2; 86 percent rolled the die in the high-power group as opposed to 60 percent of the low-power posers.

Power poses don't help boost confidence after all, Penn research shows. When a 2010 study touted that making a power pose—like a Wonder Woman ...

Initial studies on power posing indicated that engaging in expansive body positions will raise testosterone levels, lower cortisol levels, and increase risk ...

The original 2010 Carney, Cuddy, and Yap study claimed power posing increases testosterone, decreases cortisol, boosts feelings of power, and risk tolerance. Subsequent replications and meta-analyses (e.g., Ranehill et al. 2015; Simmons & Simonsohn 2017) failed to replicate hormonal effects, with behavioral effects small or absent; subjective confidence effects persist but are attributed partly to demand characteristics.

While the initial hormonal claims have been debated, research indicates that power posing can reliably influence thoughts and feelings, particularly regarding: Positive mood enhancement; Increased self-esteem; Enhanced feelings of dominance. The idea of postural feedback suggests that our body language can influence our emotions and perceptions. Expansive postures, like those used in power posing, can send signals to our brain that help us feel more confident and powerful.

If you're power posing, it's because you're trying to increase your confidence. You've got something BIG coming up that you want to accomplish and you're ...
